Lamprops Sars, 1863 .</p><p>Diagnosis. Antennule flagella well developed, accessory flagellum rarely minute. Antenna of 4 articles in female, flagellum with short articles in male. Mandible navicular or rarely truncate. Branchial apparatus with narrow gill plates. Female with natatory exopods on maxilliped 3 and pereopod 1, exopod may be natatory, rudimentary or absent on pereopod 2, exopod rudimentary or absent on pereopods 3–4. Male with natatory exopods on maxilliped 3–pereopod 4. Female without pleopods or rarely 1 or 2 pairs of rudimentary pleopods. Male with 0– 3 pairs of pleopods, if present, with process on inner ramus. Male with or without penial lobes. Uropod endopod with 2 or 3 articles.

At the time of the initial description of Archaeocuma, no other cumaceans were known with penial lobes in the male or pleopods in the female, so Băcescu (1972) considered these characters so unusual that despite the obvious affinities with the Lampropidae (flattened carapace, 3 terminal setae on the telson, large telson), a new family was proposed for the genus. However, species in the Lampropidae, Nannastacidae, and Leuconidae have now been described with penial lobes ( Campylaspenis, Chalarostylis, Eudorellopsis, Phallolamprops, Phallolampropoides, Phalloleucon, Watlingia), and in this work two new lampropid genera are described with pleopods in the female ( Pseudoarchaeocuma, Doieolamprops). Therefore, it is now clear that the presence of penial lobes in the male and pleopods in the female are not unique characters (although the combination is unique), and Archaeocuma is a member of the Lampropidae .</p><p>The family diagnosis. in Jones (1963) includes “Telson present, of medium or large size, with 3 or more end spines, rarely with 1.” The genus Pseudodiastylis has three terminal setae, although the central seta is much larger and longer than the others. It seems that Jones interpreted this setal arrangement as a single terminal seta, whereas I interpret it as similar to other lampropids in which the terminal setae are unequal in size, and a central seta may be longer or shorter than the others.</p></div>	https://treatment.plazi.org/id/03FD87BAFFE52E2164FFFCDFD04ACBBF	Public Domain	No known copyright restrictions apply.

A meaning “not”, in combination with lamprops, to indicate that these species have been removed from the genus Lamprops sensu Sars. Gender masculine.</p><p>Remarks. All the species initially included by Sars in the genus Lamprops Sars, 1863, had males with a short, clasping antenna ( Lamprops sensu Sars). However, other authors added species with males with long antennae to the genus, without addressing the disparity or discussing the dilution of the generic definition. Where known, adult males of the species in the new genus have a long antenna, extending past the pereon, necessitating their removal from Lamprops . As the majority of cumacean species have a long antenna in the male, species previously included in Lamprops sensu lato in which the adult male is unknown are also included in the new genus. It is unfortunate that the females of Alamprops and Lamprops as restricted here are indistinguishable, except by reference to the individual species descriptions. However, to maintain consistency, and in line with Sars’ (1863) original conception of the genus Lamprops, it is necessary to remove the species from the genus that have a long, or non-clasping, antenna in the adult male.</p></div>	https://treatment.plazi.org/id/03FD87BAFFE72E2064FFFECBD3F7CFD7	Public Domain	No known copyright restrictions apply.

Petropavlovsk Bay, Kamschatka Peninsula; Okhotsk Sea; Bering Sea.</p><p>Remarks. This species was originally described by Derzhavin (1926) from Kamchatka, and placed as a subspecies of A. quadriplicatus by Lomakina (1955). The current understanding of A. quadriplicatus is that the species is restricted to the northwestern Atlantic, on the American and Canadian Atlantic coasts. Thus, A. krasheninnikovi is returned to the original status of a separate species. A record of Lamprops krasheninnikovi by Zimmer (1943) from Vancouver is likely either a new species or a representative of A. augustinensis (Gerken, 2005), but the specimen was not seen. Likewise, a specimen identified by Zimmer as krashenninikovi from Corona del Mar, California (USNM 92076) is not krashenninikovi . Alamprops krasheninnikovi can be distinguished from A. longispina by the outermost pair of terminal setae on the telson being equal to the central seta; in A. longispina the outer most pair is twice as long or more than the central seta. Alamprops krasheninnikovi can be distinguished from A. quadriplicatus by the proportions of pereopods 1 and 2. In A. krasheninnikovi the dactylus of pereopod 1 is 0.8 the length of the propodus, and the dactylus of pereopod 2 is 0.6 the length of the propodus; in A. quadriplicatus the dactylus of pereopod 1 is 0.9 the length of the propodus, and the dactylus of pereopod 2 is equal to the propodus. Alamprops krasheninnikovi can be distinguished from A. augustinensis by the antennal peduncle, in A. augustinensis the first peduncle article is longer than the second, while in A. krasheninnikovi the first peduncle article is equal to the second article.</p></div>	https://treatment.plazi.org/id/03FD87BAFFE32E2464FFFF21D066CE7A	Public Domain	No known copyright restrictions apply.

The uropod exopod article 1 is 1.5 times the length of article 2, which suggests placement in Hemilamprops, not Alamprops and Lamprops, in which the uropod exopod article 1 is otherwise 0.2 or less the length of article 2.

The description of the male is necessary to be certain of the correct generic placement. In the absence of the male, the species is retained in the group ( Alamprops / Lamprops) it was placed in by Tsareva &amp; Vassilenko (1993).</p><p>Within the genus Alamprops, A. pseudosarsi is unique in having 3 lateral ridges on the carapace.

Male with long antennal flagellum.</p><p>Depth. 4–104 m.</p><p>Distribution. Western boreal Atlantic.</p><p>Remarks. This species has been problematic. The original description by Smith is from the western North Atlantic, but several subspecies have been ascribed to this species from the North Pacific, specifically krasheninnikovi from the boreal North Pacific, longispina from Peter the Great Bay and Hokkaido, Japan, as well as quadriplicatus from the Pacific coast of Canada (Derzhavin 1926; Hart 1930; Zimmer 1943). Given the limited dispersal capabilities of cumaceans, and the genetic differentiation that has been described between very close populations in South Africa (Teske 2006), it is unlikely that all of these records represent a single species. As the subspecies are morphologically distinguishable from quadriplicatus, they were returned ( krasheninnikovi) or elevated ( longispinus) to the rank of species. Based on color differences, Zimmer (1980) suggested that Hart’s “ L. quadriplicatus ” is unlikely to be the same species found on the western North Atlantic coasts of Canada and the United States. It is possible that Hart’s quadriplicatus is what was described as A. augustinensis (Gerken, 2005) .</p></div>	https://treatment.plazi.org/id/03FD87BAFFFD2E3964FFFAC4D7CECB2A	Public Domain	No known copyright restrictions apply.

However, species in the Lampropidae, Nannastacidae, and Leuconidae have now been described with penial lobes ( Campylaspenis,Chalarostlyis, Eudorellopsis, Phallolamprops, Phallolampropoides, Phalloleucon, Watlingia), and in this work two new lampropid genera are described with pleopods in the female ( Pseudoarchaeocuma, Doieolamprops). Therefore, it is now clear that the presence of penial lobes in the male and pleopods in the female are not unique characters, although the combination is unique.</p></div>	https://treatment.plazi.org/id/03FD87BAFFFB2E3C64FFFE2DD619CE41	Public Domain	No known copyright restrictions apply.

Chalarostylis elegans Norman, 1879, by monotypy.</p><p>Diagnosis. Carapace not dorsoventrally flattened, marginal carina absent, eyelobe present, pseudorostral lobes short, blunt. Antennule flagella unequal, accessory flagellum shorter than main flagellum. Mandible navicular. Maxillule palp with 2 setae. Pereopod 1 robust, with group of long, stout setae on dactylus.

Female with fully developed exopod on pereopod 2, rudimentary exopods on pereopods 3–4, without pleopods. Male with short antenna, not extending past pereon, with or without penial lobes, with 3 pairs of pleopods.</p><p>Species. C. brenkei (Mühlenhardt-Siegel, 2005), C. bruunae n. sp., C. canadensis (Vassilenko, 1988) C. elegans Norman, 1879, C. guanchi (Reyss, 1978b), C. longisetae (Corbera, 2006) .</p><p>Remarks. Chalarostylis is a deep sea genus, and the first pereopod is frequently broken off at the basis/ ischium joint. Specimens with the first pereopod broken may easily be confused with Hemilamprops, as also observed by Alberico et al. (2014). With the exception of C. canadensis, the accessory flagellum is much shorter than the main flagellum, which serves to differentiate this genus from Hemilamprops . It is possible that the incomplete specimens described as Hemilamprops sp. in Day (1978) represent another species of Chalarostylis, as the anterior margin of the carapace and the dorsal crest are spined, and the telson is less than 0.5 the length of the uropod peduncles.</p><p>The diagnoses of Dasylamprops and Chalarostylis shared the short telson and the accessory flagellum of the antennule much shorter than the main flagellum, unusual characteristics within the Lampropidae . The Dasylamprops diagnosis. also included a robust pereopod 1 with a group of stout setae on the dactylus, apparently differentiating it from Chalarostylis . However, the holotype material of Chalarostylis elegans has the first pereopods missing all articles distal of the basis, and none of the subsequently published records of Chalarostylis before 2007 included any additional description, suggesting the pereopod 1 was broken on all specimens, as is frequently encountered in cumaceans with long first pereopods, including many Hemilamprops, diastylids and gynodiastylids. Gerken &amp; McCarthy (2007) redescribed both the holotype and an additional entire specimen of Chalarostylis elegans, which included a complete, robust pereropod 1 with a group of stout setae on the dactylus. With a complete overlap of the generic diagnoses (short telson, short accessory flagellum, robust pereopod 1), it became clear that Chalarostlyis and Dasylamprops were synonymous, and Dasylamprops was the junior synonym (Gerken &amp; McCarthy 2007).</p><p>Alberico et al. (2014) suggested that the steep angle of the articulation between the merus and carpus of maxilliped 1 be added to the generic diagnosis. However, there is much variation across the Lampropidae in this angle within genera (where it has been observed), therefore it does not seem at present to be of generic value.</p></div>	https://treatment.plazi.org/id/03FD87BAFFC62E0164FFFE91D72FCC72	Public Domain	No known copyright restrictions apply.

However, the robust pereopod 1 with a group of long setae on the dactylus is distinctly Chalarostlyis, and not like the slender pereopod 1 found in Hemilamprops . The species can be distinguished from all other Chalarostylis by the combination of the serrate anterior margin of the carapace, the accessory flagellum more than 0.5 the length of the main flagellum, and the telson more than 0.5 the length of the uropod.</p><p>There is a discrepancy in the length of the male antenna in Vassilenko’s figure (Vassilenko 1990). In Figure 3, the antenna is figured with the flagellum about 4.0 the length of the fifth peduncle article, similar to the proportions seen in C. elegans, but in the full body illustration (Fig. 1, Vassilenko 1988) the flagellum appears to be much longer, and it is possible that this is an artifact of the position of the specimen. The full body seems to suggest that the male antenna is longer than that seen in other Chalarostylis males, but the individual figure of the male antenna resembles the other Chalarostylis males in having a flagellum that is short, about 4.0 the length of peduncle article 5.</p></div>	https://treatment.plazi.org/id/03FD87BAFFC22E0564FFFBF9D2E3CDE6	Public Domain	No known copyright restrictions apply.

The pereopod 3 and pereopod 4 exopods are rudimentary. The antenna was rudimentary and very small, showing no indication of the enlargement that would be expected in an immature male.

Members of Hemilamprops can be difficult to impossible to distinguish from Lamprops and Alamprops if males are not present. There are some problematic species that have been placed in Hemilamprops: H. abyssi Gamô, 1989 and H. bicarinatus Ledoyer, 1988 . Hemilamprops abyssi does not meet the definition of Hemilamprops given above, as the first article of the uropod exopod is 0.4 the length of article 2, rather than 0.5 or more the length of article 2, and is transferred to Pseudolamprops . The description of H. bicarinatus is based on two incomplete female specimens. The carapace sculpturing, which includes a marginal carina, suggests that Hemilamprops is not the correct genus, as does the reduced pereopod 5. However, without specimens that are more nearly complete, and perhaps the adult male, it is not possible to be definitive about the genus placement, so the species is retained in Hemilamprops for the present.</p></div>	https://treatment.plazi.org/id/03FD87BAFFD32E1464FFFD0DD093CCE3	Public Domain	No known copyright restrictions apply.

Within Hemilamprops, the most similar species is H. bacescui from the Weddell Sea. The two species can be differentiated by the lateral setation on the telson.

The new species is named impellucidus from the Latin im, meaning not, in combination with pellucidus, as it is most likely to be confused with Hemilamprops pellucidus .</p><p>Depth. 167–1239 m.</p><p>Distribution. Chatham Rise, Challenger Plateau, New Zealand, 38.618– 45.35°S, 168.943°E– 178.62°W.</p><p>Remarks. Hemilamprops impellucidus is most likely to be confused with H. pellucidus, as the species share an overall similarity in form and the serrate dorsal crest. However, in H. impellucidus the antennule main flagellum is of five long, slender articles, the eyelobe has lenses in both females and males, the telson is similar in length to the uropod peduncles (0.9 in the female, 1.0 in the male), and the telson terminal setae are distinctly unequal, with the central seta longer than the outer pair. In contrast, in H. pellucidus, the antennule main flagellum is of four short, stout articles, the eyelobe is without lenses in either sex, the telson is much less than 0.9 the length of the uropod peduncles, and the telson terminal setae are equal in length. In addition, reproductive individuals of H. impellucidus are 7–8.5 mm, while very immature males and females of H. pellucidus are 6–8 mm, suggesting mature individuals will likely be distinctly larger than mature individuals of H. impellucidus .</p></div>	https://treatment.plazi.org/id/03FD87BAFFA82E6764FFFC10D6E8CFD3	Public Domain	No known copyright restrictions apply.

The most similar species is Hemilamprops impellucidus n. sp., which can be differentiated by the antennule flagellum with five long slender articles, eyelobe with lenses, telson similar in length to uropod peduncles, and unequal telson terminal setae with the central seta longer than the outer pair, while in H. pellucidus the antennule flagellum is of four short, stout articles, the eyelobe is without lenses, the telson is much shorter than the uropod peduncles, and the telson terminal setae are equal in length. Another similar species is H. cristatus from the North Atlantic, which can be differentiated by four or fewer pairs of lateral setae on the telson, while in H. pellucidus there are at least five pairs of lateral setae on the telson.</p></div>	https://treatment.plazi.org/id/03FD87BAFFA32E6464FFFF21D130C961	Public Domain	No known copyright restrictions apply.

The types were inspected closely under high magnification, and a temporary stain (chlorazole black) was applied, to highlight a ridge if present; no ridge was evident. The specimens recorded as H. ultimaspei in Mühlenhardt-Siegel, 2003 have a short ridge on the carapace, as shown in her figures and as observed by this author. The ridge is consistent in that material, but is simply not present in the types. In combination with the difference in the lateral setation of the telson, the specimens recorded by Mühlenhardt-Siegel appear to be referrable to a new species of Hemilamprops, H. chilensis Gerken &amp; Haye, 2018 and not H. ultimaspei .</p><p>Ledoyer (1993) identified material from 610–1223 m in the Weddell Sea as Hemilamprops ultimaspei; however, it is clear from his illustrations that his material is neither H. ultimaspei nor H. chilensis . Ledoyer illustrated specimens without a ridge on the carapace, like H. ultimaspei, but the uropod endopod is shown with article 2 distinctly shorter than article 3, and in both H. chilensis and H. ultimaspei article 2 and article 3 are equal. In addition, the distribution is unlikely, especially in light of recent work (Teske et al. 2006) describing significant genetic structuring in closely co-located coastal populations of cumaceans. The Ledoyer material represents an undescribed species, and is thus not included in the distribution of H. ultimaspei . Additionally, material reported by Corbera (2000) as H. ultimaspei from the South Shetland Islands has the uropod endopod article 2 shorter than article 3, and therefore is also not H. ultimaspei (Corbera, pers. comm.).</p></div>	https://treatment.plazi.org/id/03FD87BAFFBC2E7A64FFFA22D1F1C82F	Public Domain	No known copyright restrictions apply.

It is likely that specimens from the North Pacific and Arctic ascribed to L. fuscatus by Hart (1930), Derzhavin (1929), Lomakina (1955, 1958), and Given (1965) are L. northwindae, a species with a very similar carapace, or possibly several species. Lamprops northwindae from the Laptev Sea can be differentiated from L. fuscatus by the lack of an antennal notch, blunt pseudorostrum, and large eyelobe. In L. fuscatus, the antennal notch is weak but present, the pseudorostrum is pointed, and the the eyelobe is small.</p><p>In the genus Alamprops, the most similar species are A. affinis, A. carinatus, A. obfuscatus, and A. serratus . In Lamprops fuscatus, the telson is longer than the uropod peduncles, while in A. affinis, A. carinatus and A. obfuscatus the telson is shorter than or equal to the uropod peduncles. The most similar species A. serratus, which has a strongly serrate anterolateral corner on the carapace, and the telson terminal setae have the outermost pair long, and the central three setae are equal in length and short. In L. fuscatus, the anterolateral corner of the carapace is smooth, and the telson terminal setae are all long, with the outermost pair slightly longer than the central three setae.</p></div>	https://treatment.plazi.org/id/03FD87BAFFBE2E7864FFF89FD299C8D8	Public Domain	No known copyright restrictions apply.

The new species can be distinguished by the combination of no antennal notch, blunt pseudorostrum and a large eyelobe. In comparison, L. fuscatus has a weak antennal notch, pointed pseudorostrum, and a small eyelobe. In addition, L. northwindae n. sp. is known from the North Pacific, while L. fuscatus was originally described from the North Atlantic. It is probable that the records of L. fuscatus from the boreal Pacific are actually L. northwindae or related species. Lamprops northwindae has the telson longer than the uropod peduncles in both sexes, which differentiates it from the similar species in Alamprops, A. affinis, A. carinatus, A. obfuscatus, in which the telson is shorter or subequal to the uropod peduncles in length. Lamprops northwindae has no antennal notch, and the anterolateral corner is entire, unlike A. serratus in which the antennal notch is present and the anterolateral corner is strongly serrate.</p></div>	https://treatment.plazi.org/id/03FD87BAFFBF2E7164FFFA7CD6FECBF8	Public Domain	No known copyright restrictions apply.

Deposition unknown. Kamchatka Peninsula, USSR. Not seen .</p><p>Diagnosis. Carapace without lateral ridges, antennal notch absent, pseudorostrum pointed, eyelobe small. Telson 1.0 length of uropod peduncles, 0 pairs lateral setae, 5 terminal setae. Uropod peduncle with 1 medial seta. Adult male entire antenna including flagellum only as long as uropod.</p><p>Depth. 0–92 m.</p><p>Distribution. Northern boreal Pacific, Bering Sea.</p><p>Remarks. There is only one other species of Lamprops with a single lateral ridge on the carapace, L. beringi; however, L. beringi and L. sarsi can be differentiated by the telson setation. In L. beringi the telson has 3 terminal setae, while in L. sarsi the telson has 5 terminal setae. The most similar species in Alamprops is A. pseudosarsi, which has three ridges on the carapace, although the posterior ridge may be quite weak.</p><p>The placement of this species in Lamprops is quite clear, as the male is without pleopods and the antenna 2 is quite short. However, uropod exopod article 1 is distinctly longer than article 2, which suggests that the use of uropod exopod article ratios is not an exceptionally useful character to differentiate genera.</p></div>	https://treatment.plazi.org/id/03FD87BAFFB62E7164FFFA8CD6DBCDB0	Public Domain	No known copyright restrictions apply.

Mesolamprops bispinosus Given, 1964, by original designation.</p><p>Diagnosis. Carapace not dorsoventrally flattened, marginal carina absent, eyelobe present, pseudorostral lobes short, blunt. Antennule flagella well developed, accessory flagellum at least 0.5 length of main flagellum. Mandible navicular. Maxillule palp with 2 setae. Pereopod 1 slender, basis as long as all other articles together. Pereopod 5 longer than pereopod 4 basis. Telson long, at least 2/3 length of uropod peduncles. Uropod endopod of 3 articles. Uropod exopod article 1 at least 0.5 length of article 2. Female with fully developed exopod on pereopod 2, rudimentary exopods on pereopods 3–4, without pleopods. Male with long antenna, extending past pereon, without penial lobes, with 2 pairs of pleopods.</p><p>Species. Mesolamprops abyssalis Reyss, 1978a, M. bispinosus Given, 1964, M. denticulatus Ledoyer, 1988, M. dillonensis Gladfelter, 1975, M. hartleyi Shalla &amp; Bishop, 2007, M. japonicus (Zimmer, 1937) .</p><p>Remarks. Given’s original description (1964) of the genus included reduced pleopods in the male, in which the exopod, or lateral ramus, which is normally bi–articulate is reduced to a small projection. However, subsequent papers (Gladfelter 1975; Reyss 1978a; Ledoyer 1983) included species that possess two pairs of pleopods, but the state of the pleopods varies from that described by Given (1964). In Mesolamprops dillonensis, the pleopod is illustrated with equal rami, with a bi–articulate lateral ramus and a uni-articulate medial ramus. In M. abyssalis the pleopod is illustrated with 2 equally small uni-articulate rami, and in M. denticulatus the pleopod is illustrated with unequal rami, and the shorter lateral ramus is bi-articulate. The pleopod was not illustrated for M. hartleyi by Shalla &amp; Bishop (2007). The only species with a pleopod that is like that of M. bispinosus is M. japonicus . In the additional description of M. japonicus provided by Tsareva (1999), it is clearly illustrated with a pleopod in which the lateral ramus is reduced to a small projection.</p><p>The species described by Gamô (1999) as Mesolamprops bacescui is clearly a member of the Diastylidae, as it has long articles in the male antennal flagellum, two pairs of pleopods without the medial process in the adult male, two terminal setae on the telson in both males and females, and distinct pre and post-anal sections of the telson. In comparison, all male lampropids with fully developed pleopods have a process on the medial ramus, short articles in the adult male antenna flagellum, no obvious pre and post-anal division of the telson, and three or more terminal setae on the telson. Thus, this species is hereby referred to Diastylis, as Diastylis bacescui (Gamô 1999) comb. nov.</p></div>	https://treatment.plazi.org/id/03FD87BAFFB72E7064FFFF21D7D2CE8A	Public Domain	No known copyright restrictions apply.

Sars (1887) defined the genus Paralamprops by the combination of the flattened carapace and the lack of a maxillule palp, noting that the lack of the palp was extremely unusual. Some subsequent authors ignored this character, and added species to the genus with a flattened carapace that also possess a normal maxillule palp with 2 setae. There are some species in which the state of the palp is not known. A flattened carapace is a character shared with several other genera, and is almost certainly associated with the water content and grain size of the sediments on which the organisms live. Therefore, I am defining Paralamprops as without the maxillule palp, sensu Sars, and removing species that possess a maxillule palp, and those in which the state of the maxillule palp is unknown, to the genus Platytyphlops . Species in which the palp state is unknown are removed to Platytyphlops, because the basal state of the palp is to be present with 2 setae.</p></div>	https://treatment.plazi.org/id/03FD87BAFF892E4E64FFFBC2D118CDB7	Public Domain	No known copyright restrictions apply.

In Hemilamprops, pereopod 1 has the basis shorter than the rest of the articles together, while in the new genus pereopod 1 has the basis longer than all other articles together. In Lamprops, article 1 of the uropod exopod is usually less than 0.5 the length of article 2, while in the new genus, article 1 of the uropod exopod is much greater than 0.5 the length of article 2. Unfortunately, without adult males, there is no way to differentiate between the Phallolamprops and Phallolampropoides, except by differentiating among the different species.</p></div>	https://treatment.plazi.org/id/03FD87BAFF9C2E5A64FFFA85D687CAE2	Public Domain	No known copyright restrictions apply.

Phallolamprops californiensis females can be distinguished from P. pribilofensis females by the pseudorostrum, which is blunt in side and dorsal views in P. californiensis, and pointed in side and dorsal views in P. pribilofensis . Also, in P. californiensis the telson terminal central seta and outer pair of setae are long, and the inner pair is very short, while in P. pribilofensis the terminal setae are much more equal in length. The adult males can be distinguished from each other by the form of the penial lobes and the ventral elaboration of pleonites 1 and 2. In P. californiensis the penial lobes are distinctly hooked, pointing anteriorly, while in P. pribilofensis the penial lobes are simple tubes, and do not appear hooked. In P. californiensis the ventral structure on pleonite 1 has only two pairs of setae, while the ventral structure on pleonite 1 in P. pribilofensis has seven pairs of setae.</p></div>	https://treatment.plazi.org/id/03FD87BAFF9D2E5C64FFFE48D747CC3F	Public Domain	No known copyright restrictions apply.

Pribilof Islands, Bering Sea, 56°N, 169°W</p><p>Remarks. Female Phallolamprops californiensis can be distinguished from female P. pribilofensis by the pseudorostrum, which is blunt in side and dorsal views in the former, and pointed in side and dorsal views in the latter. Also, in P. californiensis the central and outer pair of setae are long, and the inner pair is very short, while in P. pribilofensis the terminal setae are much more equal in length. The adult males can be distinguished from each other by the form of the penial lobes and the ventral elaboration of pleonites 1 and 2. In P. californiensis the penial lobes are distinctly hooked, pointing anteriorly, while in P. pribilofensis the penial lobes are simple tubes and do not appear hooked. In P. californiensis the ventral structure on pleonite 1 has only two pairs of setae, while the ventral structure on pleonite 1 in P. pribilofensis has seven pairs of setae.</p></div>	https://treatment.plazi.org/id/03FD87BAFF9B2E5564FFF9E5D188CE03	Public Domain	No known copyright restrictions apply.

Male with short antenna, not extending past pereon, without penial lobes, with 3 pairs of pleopods.</p><p>Species. Platysympus brachyurus (Zimmer, 1907), P. camelus Day, 1978, P. compressus Day, 1978, P. depressus Day, 1978, P.japonicus Gamô, 1975, P. muranoi Gamô, 1980, P. ovalis Gamô, 1987, P. pacificus Corbera, 2006, P. phylloides Day, 1978, P. quadrangulatus Gamô, 1987, P. tricarinatus Hansen, 1920, P. typicus (Sars, 1870) .</p><p>Remarks. The most similar genera to Platysympus are Aplatysympus and Paraplatysympus, which are differentiated by the state of the maxillule palp and pereopod 5. In Aplatysympus pereopod 5 is longer than the pereopod 4 basis, as in Platysympus, but the maxillule palp is present and bears 2 setae. In Paraplatysympus the maxillule palp is present and bears 2 setae, and pereopod 5 is shorter than the basis of pereopod 4.</p></div>	https://treatment.plazi.org/id/03FD87BAFF692EAD64FFFA11D6AECB2B	Public Domain	No known copyright restrictions apply.

North Atlantic, Norway to Mediterranean Sea.</p><p>Remarks. There has been discussion about the lack of distinction between Platysympus typicus and P. tricarinatus, due to the varying presence of “dorsal keels” in P. typicus, as discussed in Corbera &amp; Galil (2001, and references within). However, Hansen (1920) illustrated the telson of P. tricarinatus with lateral setae, and there has been no reference to P. typicus having lateral setae on the telson. The edges of the telson may be serrate, and the strength of the serrations may vary in P. typicus (Corbera &amp; Galil 2001), but there are no setae present.</p></div>	https://treatment.plazi.org/id/03FD87BAFF652EA264FFFAEAD75ACDD1	Public Domain	No known copyright restrictions apply.

The species placed in Platytyphlops resemble Paralamprops, but possess a maxillule palp with 2 setae, and those for which the state of the palp is unknown. When Sars (1887) established Paralamprops, he noted the unusual absence of the maxillule palp. Despite this, species with a palp were ascribed to Paralamprops by Fage (1929), Gamô (1984), Day (1978), Petrescu &amp; Wittmann (2003), and Jones (1971). Most of these authors did not address the issue of the palp, ignoring the absence of the palp as a defining character for the genus. Calman (1912) and Day (1978) did address the issue of the palp, acknowledging the taxonomic significance of the palp absence. However, while both Calman (1912) and Day (1978) suggested that Paralamprops should be separated into two genera, those with and without the palp, neither of them did so, and in fact Day synonymized Platytyphlops, a genus with a maxillupe palp with 2 setae, with Paralamprops . Day’s (1978) justification for mixing species with a palp and without a palp in the genus Paralamprops sensu lato was the difficulty in accessing the character as well as the lack of information for some species. However, both of these difficulties exist for mature male characters used in generic definitions, when it is very common in the Cumacea to encounter only females or immature males. However, the male characters are utilized because they are seen as of considerable systematic value, as is the palp. In keeping with Sars’ (1887) original concept of Paralamprops as lacking a maxillule palp, all species placed in Paralamprops to date that possess the palp are removed to Platytyphlops . As the basal state of the maxillule palp is to be present and with 2 setae, it is most conservative to assume that species in which the state of the palp is unknown possess a palp with 2 setae. Thus, species formerly placed in Paralamprops in which the state of the palp is unknown are also included in the genus.</p></div>	https://treatment.plazi.org/id/03FD87BAFF662EA164FFFF21D03CCFEE	Public Domain	No known copyright restrictions apply.

Platytyphlops echinatus is most similar to P. bamberi, P. petrescui and P. tuberculatus . Platytyphlops bamberi is easily distinguished by the presence of spines on the carapace ventral of the marginal carina, and unequal terminal setae of the telson; in P. echinatus there are no spines on the carapace ventral of the marginal carina, and the telson terminal setae are subequal in length. Platytyphlops tuberculatus is easily distinguished by the expanded article 1 of the antennule; in P. echinatus article 1 of the antennule is the same width as article 2. Platytyphlops petrescui can be distinguished by the carapace, pleonites and pereonites covered with blunt tubercles, setose antennule, equal flagella of the antennule, telson equal to the uropod peduncles, and six pairs of lateral setae on the telson; in comparison, in P. echinatus the dorsal surfaces of the carapace and pereonites are covered with sharp spines, the antennule has only two setae, the accessory flagellum is distinctly shorter than the main flagellum, the telson is shorter than the uropod peduncles, and there are only two pairs of lateral setae on the telson.</p></div>	https://treatment.plazi.org/id/03FD87BAFF7C2EBE64FFF9BFD2ADC9B7	Public Domain	No known copyright restrictions apply.

The species is named in honor of Iorgu Petrescu, in recognition of his extensive contributions to cumacean systematics.</p><p>Depth. 3658–3674 m</p><p>Distribution. Weddell Sea; Tasman Plain, off Australia.</p><p>Remarks. This species is similar to Platytyphlops echinatus and P. tuberculatus, in that the ornamentation of the carapace is dorsal to the marginal carina, and there are no other obvious ridges. Platytyphlops petrescui can easily be distinguished from P. tuberculatus by the antennule; in P. tuberculatus the first article of the antennule is greatly expanded, but in P. petrescui the first article is the same width as the second article. Platytyphlops petrescui can be distinguished from P. echinatus by the type and pattern of ornamentation, the setation of the antennule, and the proportions and armature of the telson. In P. echinatus the carapace and dorsal surfaces of the pereonites are covered in spines, the antennule peduncle has only two small setae, the accessory flagellum is shorter than the main flagellum, the telson is distinctly shorter than the uropod peduncles, and there are only two pairs of lateral setae on the telson; in comparison, in P. petrescui the dorsal surfaces of the carapace, pereonites and pleonites are covered in blunt tubercles, the antennule peduncle bears many long plumose setae, the flagella are equal in length, the telson is as long as the uropod peduncles, and the telson has six pairs of lateral setae.</p></div>	https://treatment.plazi.org/id/03FD87BAFF722E8964FFFB51D1A6C923	Public Domain	No known copyright restrictions apply.

The new genus is similar to Paralamprops and Platytyphlops in overall form, being dorsoventrally flattened with a marginal carina</p><p>Species. Quasiparalamprops chathamensis n. gen., n. sp.</p><p>Remarks. Quasiparalamprops is extremely unusual in that the maxillule palp is present, but apparently bears no setae. Among the telson bearing families, Diastylidae, Gynodiastylidae, Lampropidae and Pseudocumatidae, the absence of the maxillule palp is restricted to a few genera within the Lampropidae, as is the presence of a single seta on the maxillule palp. Quasiparalamprops is the first genus having a palp without setae. On the adult male paratype of Q. chathamensis, both maxillules were observed very closely at high magnification and neither setae nor setal bases (indicating broken setae) were observed on the palp. The maxillule of the female was not observed, because it could not be accessed without destroying the carapace of the holotype of Q. chathamensis, an unacceptable amount of damage to a holotype. While it is possible that this male is a single aberrant individual, there are no indications of aberrant development in the maxillule, the two endites are of the typical form with the typical arrangement and length of setae. It is unlikely that this is a sexually dimorphic difference, adult male mouthparts are typically similar or identical to functional mouthparts of the female. It is also unlikely that this is a case of end stage degeneration of mouthparts in the terminal male. Degenerate mouthparts have been observed in the ovigerous females of Atlantocuma Băcescu &amp; Muradian 1974 and Pseudopicrocuma Akiyama 2012 (Akiyama 2012), but these are unusual cases, and degenerate mouthparts have never been reported in the adult male of any cumacean. In the case of Atlantocuma, the degeneration included decalcified mandibles, reduced setation on the maxilla, maxillules, maxilliped 1 and maxilliped 2, as well as slender maxillipeds 1 and 2, but the maxillule palp was still present and had 2 setae. In the case of Pseudopicrocuma, the degeneration included decalcified mandibles, reduced or lost setae on the maxillae and maxillules, and reduced setae on maxipellids 2 and 3, but the maxillule palp again was present and bore 2 setae.</p></div>	https://treatment.plazi.org/id/03FD87BAFF422E8464FFF9F9D016C900	Public Domain	No known copyright restrictions apply.

Platytyphlops lathierae Reyss, 1978b .</p><p>Remarks. Platytyphlops was erected by Stebbing (1912) to accommodate a new species, P. peringueyi, based on males without pleopods. However, Stebbing’s material only included early juvenile males. Stebbing (1912) included Platyaspis orbicularis in Platytyphlops, because the description of the species by Calman (1905) was incomplete and adult males were not known. However, Calman (1912) completed the description of Platyaspis orbicularis, including adult males with 3 pairs of pleopods, and transferred the species to Paralamprops (transferred herein to Platytyphlops). Day (1978) described the adult male of P. peringueyi, with 3 pairs of pleopods, and also transferred the species to the genus Paralamprops (transferred herein to Platytyphlops). This effectively placed Platytyphlops in synonymy with Paralamprops, but Platytyphlops has been resurrected (see remarks for Platytyphlops). However, Reyss (1978b) described a new species, Platytyphlops latheriae, a species in which the males are without pleopods, but which cannot be accommodated in Platytyphlops as resurrected. Băcescu (1988) declared “ Platytyphlops latheriaeí ” incertae sedis and suggested that a new genus would need to be erected to accommodate the species. The genus Reyssia is therefore erected for the species described as latheriae Reyss, 1978b .</p></div>	https://treatment.plazi.org/id/03FD87BAFF582E9F64FFFD0DD3EECC7D	Public Domain	No known copyright restrictions apply.

Watlingia cassis and W. chathamensis are very similar, but can be distinguished by the number of telson lateral setae and the carapace morphology. In W. cassis the telson bears 3 pairs of lateral setae; in W. chathamensis the telson bears 4–5 pairs of lateral setae. In W. cassis the carapace is without tubercles, while in W. chathamensis the carapace has 1–3 pairs of large tubercles, a pair of posterior dorsal swellings, and a median posterior crest. The posterior dorsal swellings are the most easily visible distinguishing characteristic, making a distinct dorsal hump in the side view, while the tubercles vary amongst individuals and may not be very obvious. In addition, W. chathamensis is larger than W. cassis, being closer to 5 mm in length while W. cassis is closer to 3 mm. In the samples examined, W. chathamensis is also much more commonly encountered than W. cassis, although they do co–occur.</p></div>	https://treatment.plazi.org/id/03FD87BAFF5B2E9064FFFF21D368CED0	Public Domain	No known copyright restrictions apply.
