Sydney Harbour, NSW.</p><p>Remarks. As recognised previously by Lang (1973) and others, the brief original description of a female specimen of Paratanais ignotus Chilton, 1885 relates to a species of Leptochelia rather than to Paratanais, as indicated by a uropod endopod with 5–7 articles, and a pair of spiniform processes on antennule article-2. In an attempt to clarify affinities of this poorly-known species, collections of epifaunal invertebrates were made at the type location, Mrs Macquarie’s Chair in Sydney Harbour. No leptocheliids were obtained in these collections, the only tanaidacean recorded comprising Zeuxo normani (Richardson 1905), a species likely introduced at that site (Edgar 2008). Conditions at the type locality had, however, degraded badly over the past century, with little macrophyte cover, relatively high silt levels and high turbidity.</p><p>Accordingly, the search for Leptochelia ignota was expanded to Quarantine Bay on the sheltered inner side of North Head in Sydney Harbour, a site ca. 8 km seaward from the type locality but with dense macro-algal cover and better water quality. Numerous Leptochelia of the species illustrated were collected. With minor exceptions in characters as discussed below, collected specimens matched the morphological description of Leptochelia ignota by Chilton (1885), which included figures of antennules, antennae, pereopods 1, 2 and 5, and uropods. Consequently, the newly-collected individuals are attributed to L. ignota . A neotype has been assigned given that Chilton’s holotype of Paratanais ignotus was deposited in an unknown location and is assumed lost.</p><p>Labelling of the figures of pereopods 2 and 5 and uropods is inconsistent in Chilton’s original description. The figure caption to figs 2a–c in his plate XLVII describes these illustrations as belonging to “ Paratanais tenuicornis . Haswell. (? or P. i g n o t u s, sp. nov.)”, while the text description for Paratanais ignotus references these figures as pertaining to the type description of P. ignotus . Given that the illustrated appendages clearly belong to a leptocheliid species rather than Paratanais tenuicornis Haswell, 1882 —now Zeuxo tenuicornis (Haswell, 1882), following Sieg (1980) —we consider them to unambiguously relate to L. ignota, the caption label perhaps reflecting initial uncertainty in Chilton’s mind as to whether P. ignotus differed from P. tenuicornis . Chilton (1885) considered the two very similar, stating “( P. ignotus) is very closely related to P. tenuicornis, Haswell, but differs in the presence of spines on the undersurface of the peduncle of the lower antennae and other minor points”.</p><p>Although brief by today’s standards, sufficient information is provided in Chilton’s description for specimens collected from Quarantine Bay to be assigned to L. ignota with reasonable confidence. In common with our Quarantine Bay specimens, Chilton’s illustrations indicate that the mature female L. ignota possess a uropod endopod with five articles (although five to seven is mentioned in the P. ignota type description), a uropod exopod with a single article about equal in length to article-1 of the endopod, an antennule with three longer articles plus minute distal article, a pereopod-1 basis with length about four times width, a propodus slightly shorter than dactylus plus claw, and an antennule article-1 about three times longer than wide. The relative proportions of antennule, antennae and pereopod articles in Quarantine Bay specimens and L. ignota generally match well, other than that the propodus of pereopods 2 and 5 appears slightly more elongate in the L. ignota description, and the basis of pereopod-5 narrower. Chilton’s written description does, however, state that the basis of pereopod-5 is “very stout, greatest width half its length”, which agrees with our Quarantine Bay specimens and differs from the illustration provided for P. ignotus, where this ratio is about 2.3:1 rather than 2.0:1. Setation of appendages of the Quarantine Bay specimens matches well with illustrated setation for L. ignota, with the notable exception that our specimens possess a distal seta on the basal antenna article whereas this seta is lacking on the L. ignota figure.</p><p>The validity of L. ignota as a species name remains to be confirmed because of the possibility that the species described by Haswell as L. ignota is the same as another member of the Leptochelia dubia / savignyi complex described from an overseas location prior to 1885. Although it is now clear that the Leptochelia dubia / savignyi complex includes numerous sibling species, many localised in distribution (Larsen &amp; Rayment 2002; Bamber 2008; Bamber 2010), it is also possible that one or more circumglobal Leptochelia species exist. Any species strongly associated with fouling organisms on ship’s hulls would have been readily transported across ocean basins in the nineteenth century, a period when Sydney Harbour was a major shipping port. Whereas the presence of six or seven long setae on the maxilliped basis unambiguously distinguishes the species diagnosed here from other welldescribed species of Leptochelia (see Table 1 in Bamber 2005), a comparative examination of type specimens in the Leptochelia dubia / savignyi complex that predate L. ignota ( L. algicola Harger, 1878, L. dubia Kröyer, 1842, L. edwardsi Kröyer, 1842, L. kroyeri Kossmann, 1880, L. limicola Harger, 1878, L. neapolitana Sars, 1882, L. savignyi Kröyer, 1842) is needed to definitively resolve the status of L. ignota (see Lang 1973).</p><p>With respect to other Australian Leptochelia species, female specimens recognised here as L. ignota are very similar to L. opteros Bamber, 2008, keying as that species in Bamber (2008). These two taxa differ from each other primarily in minor details of setation and the proportions of pereopod articles. Female Quarantine Bay specimens possess three rather than a single spiniform setae on the carpus on pereopods 2 and 3, maxilliped basis with seven rather than four long setae extending to third palp article; and wider pereopod-1 basis, longer merus on pereopods 1, 4 and 5, and longer uropod exopod than L. opteros .</p><p>Male Quarantine Bay specimens differ in a number of characteristics from the L. opteros male figured by Bamber (2008), keying as L. daggi . Compared to L. opteros, Quarantine Bay specimens possess a more elongate carpus and propodus, greater separation between the two tooth-like apophyses on the cutting edge of the fixed finger, and propodus on pereopod-1 that is similar in length rather than shorter than the merus plus carpus together. Quarantine Bay males differ from L. daggi in possessing a uropod exopod that is longer than the proximal article of endopod, antennule second article less than half length of first article (c.f. 85% length in text description of L. daggi, but with figure showing about half length), and a cheliped dactylus that is smoothly curved without proximal setose crenulations along the cutting edge.</p><p>The possibility that the male specimens diagnosed and illustrated here belong to a species that differs from the figured females cannot be excluded, although all females collected in Sydney Harbour appeared to belong to a single species, as did the set of males.</p></div>	https://treatment.plazi.org/id/4D340E78FFC3905046A3FCA2FDDEFF5A	Public Domain	No known copyright restrictions apply.

This species is named in honour of David Evans, CSIRO senior technician, who assisted with field surveys at the type location.</p><p>Distribution. Rottnest Island to Dongara, WA.</p><p>Remarks. Leptochelia evansi n. sp. belongs to a well-defined group of Leptochelia with males possessing chelipeds that are long, slender and chelate—a group referred to by Lang (1973) as Leptochelia group 1, and by Bamber (2005) as Leptochelia minuta aggregate. This group includes L. erythraea (Kossman, 1880), L. forresti (Stebbing, 1896), L. longichelipes (Lang, 1973), L. longimana Shiino, 1963, L. minuta Dana, 1849, L. mirabilis Stebbing, 1905 and L. vimesi Bamber, 2005 . The smoothly curving fixed finger and dactylus of the male distinguish L. evansi from others in the group. Leptochelia forresti, L. longichelipes and L. longimana all possess a male cheliped with a fixed finger that has a turning point in convexity (apophysis) about one-third distance to end (see Shiino 1963; Lang 1973), rather than smoothly curved as in L. evansi . The chelipeds of Leptochelia mirabilis are about twice as long as the body (Brown 1957), and both this species and L. minuta possess a protuberant process at the distal end of the inner margin of the fixed finger (Larwood 1954). Leptochelia erythraea differs from L. evansi in inter alia having an antennule article-3 that is more than half (cf. about one-sixth) the length of article-2 (Larwood 1954).</p><p>The only previously-known Australian species in this group, L. vimesi from Albany, Western Australia (Bamber 2005), possesses prominent hyposphenia below pereonites 2–4. It also differs from L. evansi in possessing a longer antennule (three-quarters body length), cheliped dactylus with low apophysis on inner margin, and uropod with two-articled exopod and six-articled endopod in well-developed males.</p></div>	https://treatment.plazi.org/id/4D340E78FFCA905546A3FEF9FC2DFA31	Public Domain	No known copyright restrictions apply.

The name recognises the lifetime studies of Gary Poore on the systematics of temperate Australian crustaceans.</p><p>Remarks. Species within the genus Leptochelia show a pronounced cline in the degree of attenuation of male characters (antennules, antennae, cheliped, pereopods, uropods), with Leptochelia gadgeti at the most elongate extreme and species belonging to the Leptochelia dubia complex relatively compact. Species now assigned to the genus Poorea comprise a homogeneous group located at the robust end of this cline, with compact antennules and chelipeds, in particular. Males are immediately distinguished from Leptochelia species by the compact cheliped propodus at right angles to the main cheliped axis. The genus includes three known species, Poorea wrighti n. sp., Poorea johannesi n. sp. and Leptochelia nobbi Bamber, 2005, which is transferred here to Poorea as Poorea nobbi n. comb.</p></div>	https://treatment.plazi.org/id/4D340E78FFD3904946A3FEDAFF38FA13	Public Domain	No known copyright restrictions apply.

Similar to female other than with more and longer setae.</p><p>Etymology. This species is named in honour of Alistar Robertson for initiating investigations of seagrass epifauna that led to this study.</p><p>Distribution. Rottnest Island to Dongara, WA.</p><p>Remarks. Bird (2011) noted a number of major character differences that distinguished species in the genera Konarus and Parakonarus from Pseudoleptochelia, including, for females, stout antennules, a lack of spine-like processes on antenna articles 2–3, a dense group of setae on the ventral cheliped merus, a cheliped carpal cuff, similar meral setation on pereopods 4–6, and elongate propodus on male cheliped. He recognised a single Parakonarus species ( Parakonarus kopure) and two species of Konarus ( Konarus crassicornis and Konarus cheirus). Features that differentiate female Parakonarus from Konarus include pereonites 1–3 together shorter rather than about equal to total length of pereonites 4–6, greater number of spiniform setae on pereopods (e.g. carpus of pereopods 4 and 5 with three small spiniform setae rather than two), and uropod exopod with one rather than two articles.</p><p>Parakonarus robertsoni n. sp. has close affinities with P. kopure . For females, P. robertsoni differs from P. kopure in antenna article-3 possessing two rather than one distal setae, maxilliped basis possessing four rather than five distal setae, and uropod endopod possessing six rather than five articles; for males, the antennule flagellum is longer (11 rather than 7 or 8 articles), and, most notably, the cheliped propodus is four times rather than twice the length of the opposed fixed finger.</p><p>Female P. robertsoni is also close to southwestern Australian Leptochelia fairgo Bamber, 2005, differing in subtle features only—about eleven rather than five ventral setae on the cheliped merus, wider cheliped carpus, and a longer, more slender uropod with relatively shorter exopod. Bird (2011) also noted the close relationship between P. k o p u re and L. fairgo, remarking that L. fairgo “shares certain characters with Parakonarus, such as stout antennules, thin setae on antenna articles 2–3, a dense setal group on the cheliped merus, a cheliped carpal cuff, similar meral setae on pereopods 4–6 and a subchelate male cheliped with an inferior carpal process.” These features are shared with P. robertsoni . The original description of L. fairgo makes no mention of an obvious demarcation of the second thoracomere, as is present in both P. robertsoni and P. kopure, although inspection of type specimens indicates that this demarcation is also present in L. fairgo (Andrew Hosie, Western Australian Museum, pers. comm.). Given the close relationships between these three taxa, L. fairgo is transferred to the genus Parakonarus as Parakonarus fairgo n. comb.</p><p>Male P. robertsoni differ from P. fairgo in the form of the cheliped carpus, the distal margin being relatively straight rather than produced into a pronounced apophysis. Antenna article- 5 in male P. robertsoni is also considerably more elongate than in L. fairgo, and the cheliped merus possesses many more setae. This latter feature, plus similar slender uropods, and co-occurrence in the same samples, unify the male and female specimens described here.</p><p>In addition to collections at the temperate type location near Albany, WA (Bamber 2005), P. fairgo has been recorded at subtropical Moreton Bay, Queensland (Bamber 2008). Notably, however, female specimens from Moreton Bay attributed to P. f a i rg o possessed more setae on the cheliped merus than specimens collected at Albany, no males were examined, and the collection locations are widely-separated geographically (~ 4,000 km coastal distance) and biophysically (~6o water temperature difference); consequently, it seems likely that the Moreton Bay taxon represents a sibling species rather than being conspecific. If this supposition is correct, then at least four Parakonarus species exist— P. fairgo, P. robertsoni, P. k o p u re and the undescribed Moreton Bay species.</p><p>Another Australian leptocheliid species, Pseudoleptochelia straddi Bamber 2008, could potentially belong to Parakonarus, given the elongate dactylus of the male cheliped that align this species more closely with Parakonarus and Konarus than with other Pseudoleptochelia, and 11-articled antennule flagellum. No female P. straddi are known. However, P. straddi is immediately distinguishable from known Parakonarus species because of the presence of a large rounded apophysis on the ventral margin of the cheliped propodus, and may in fact comprise the male corresponding with females attributed to Konarus cheiris at Moreton Bay (Bird 2011, Bamber pers. comm.).</p><p>The habitat preference of P. robertsoni appears distinct from other known Australian Parakonarus taxa but is similar to that of P. kopure in New Zealand. Parakonarus robertsoni is only known from algae and seagrasses in the shallow sublittoral fringe around low water mark (&lt;1 m depth), whereas P. fairgo appears restricted to sandy substrata, in water depths of 23–40 m in W. A. and in 3–10 in Moreton Bay (Bamber 2008).</p></div>	https://treatment.plazi.org/id/4D340E78FFD8907A46A3FA10FB5CF83A	Public Domain	No known copyright restrictions apply.
