The unifying feature of all genera in this tribe is that the propleura extend mesad to meet at the midline, thereby concealing most or all of the prosternellum. Cataractocoris was recently revised (Sites et al. 2013) and includes three species in Mesoamerica. Carvalhoiella also was recently revised (Rodrigues et al. 2016) and includes five species in the Neotropics. Hygropetrocoris is monotypic and was described from two male specimens collected on a rock seep in Guyana (Sites 2015). Ambrysus occurs from the northwestern United States (La Rivers 1951, Clark 2014) south to Argentina (La Rivers 1971) and its 92 species make it the most species-rich genus of Naucoridae (see Reynoso-Velasco et al. 2016, Reynoso-Velasco &amp; Sites 2016a, b).</p></div>	https://treatment.plazi.org/id/03BB115251249B6A479FFD45FEECFB83	Public Domain	No known copyright restrictions apply.

News 45: 197–201 (original description).</p><p>Ambrysus (Syncollus) maldonadus: La Rivers 1965 . Biol. Soc. Nevada Occas. Pap., 4: 5 (subgenus designation).</p><p>Diagnosis. Body length 10.24–11.20 mm. The dorsum is shiny. A series of pits lines the anterior margin of the posterior transverse band on the pronotum (Fig. 1). Tergum VI of the male lacks an accessory genitalic process (Fig. 2). The mesal margins of the laterosternites (evident on segments III–VI of both sexes) are slightly offset from one another and the abdominal venter is brown with a wide, glabrous, yellow marginal band. The midline of sterna V–VIII (males) and V–VII (females) are mostly glabrous and impubis. The pseudoparameres (medial lobes of tergum VIII) are large, broad, posterolaterally directed, with apices broadly rounded and overlapping the lateral lobes (Fig. 3). The proctiger is setose in the middle third and nearly devoid of setae in the lateral thirds (Fig. 5), and the parameres have an apical tuft of elongate setae (Fig. 6). The ventral margins of the phallosoma are mostly unmodified, although sclerotized lobes overlap near the base of the endosoma (Fig. 7). The distal margin of the female subgenital plate is broadly convex medially with roundedly-produced posterolateral corners (Fig. 4).</p><p>Discussion. In the original description, La Rivers (1954) recognized the distinction of A. maldonadus from other species of Ambrysus because of the "conspicuous black procts" (=pseudoparameres or medial lobes of tergum VIII) and the outline of the subgenital plate. Later, La Rivers (1963, 1965) further recognized the degree to which this species was atypical by suggesting that it might merit its own subgenus. In the original description of Ambrysus montandoni, La Rivers (1963) made extensive comparisons with A. maldonadus, which he considered to be closely related.</p><p>This species is known only from Venezuela and bears superficial resemblance to Carvalhoiella nitida in that their size, shape, and glossy appearances are similar; however, Ambrysus maldonadus exhibits other diagnostic attributes consistent with Carvalhoiella, including the loss of setae on the abdominal mediosternites, the head is not produced anteriorly, the anterior margin of the pronotum is only slightly concave to receive the head, the mesal margins of the laterosternites are diagonally offset from one another, the ventral abdominal lateral band is wide, and the pseudoparameres are large and posterolaterally directed (Table 1). It lacks many of the distinguishing features of the genus Ambrysus, including deep invagination of the head into the pronotum, continuous ventral abdominal hair pile, continuous mesal margins of the laterosternites, narrow ventral abdominal lateral band, small male pseudoparameres, and the male accessory genitalic process of tergum VI (Table 1). Thus, Ambrysus maldonadus is transferred to the genus Carvalhoiella .</p><p>Type locality: Venezuela, Territorio Amazonas, Mount Marahuaca, Upper Cunucunuma River.</p><p>Type repository: California Academy of Sciences (holotype ♂ by original designation).</p><p>Material examined.

Body length 11.20–12.96 mm. The dorsum is tuberculate, dull, and irregularly mottled (Fig. 8). A sharp sulcus marks the anterior margin of the posterior transverse band on the pronotum. Tergum VI of the male lacks an accessory genitalic process (Fig. 9). Laterosternites are absent on III–V (males) and III–IV (females) and the abdominal venter is lightly colored with a wide, glabrous, yellow marginal band. The midline of sterna V–VIII (males) and V–VII (females) are mostly glabrous and impubis. The pseudoparameres are large, broad, sharply angled posterolaterad, with angulate apices, and overlapping and extending beyond the lateral lobes of tergum VIII (Fig. 10). The proctiger is setose in the lateral thirds and nearly devoid of setae in the middle third (Fig. 11). The parameres have an apical tuft of elongate setae (Fig. 12). The ventral margins of the phallosoma have two hemispherical, lamellate, sclerotized lobes near the base of the endosoma (Fig. 13). The distal margin of the female subgenital plate is deeply cleft medially (see Rodrigues et al. 2012, Fig. 8).</p><p>Discussion. The expression of laterosternites has been partially suppressed in this species. Laterosternites III– V in males and III–IV in females are absent, and the mesal margin of V in females is incomplete; the laterosternites are complete thereafter, although difficult to discern beneath the dense hair pile. Although this large species is superficially reminiscent of Cataractocoris, it shares diagnostic attributes consistent with Carvalhoiella, including the loss of setae on the abdominal mediosternites, the head is not produced anteriorly, the anterior margin of the pronotum is only slightly concave to receive the head, the mesal margins of the laterosternites are diagonally offset from one another, the ventral abdominal lateral band is wide, and the pseudoparameres are large and posterolaterally directed (Table 1). It lacks many of the distinguishing features of the genus Ambrysus, including deep invagination of the head into the pronotum, continuous ventral abdominal hair pile, continuous mesal margins of the laterosternites, narrow ventral abdominal lateral band, small male pseudoparameres, and male accessory genitalic process of tergum VI (Table 1). Thus, Ambrysus montandoni is transferred to the genus Carvalhoiella .</p><p>This species is known only from the Guiana Shield in Brazil, Guyana, and Venezuela. It is perhaps most famously known from El Tobogan de la Selva in Venezuela, which is a large, smooth, rolling granitic slide where water flows in a laminar fashion. Carvalhoiella montandoni can be found here along with C. maldonadus in cracks in the rock and under dead leaves. At El Tobogan, this species was collected with Ambrysus shorti Sites, Carvalhoiella maldonadus (La Rivers) (Naucoridae), Fontidessus toboganensis Miller (Dytiscidae), Berosus garciai Oliva &amp; Short, and Oocyclus petra Short &amp; García (Hydrophilidae) .</p><p>Type locality: Venezuela, Territorio Amazonas, Mount Marahuaca, Upper Cunucunuma River.</p><p>Type repository: California Academy of Sciences (holotype ♂ by original designation).</p><p>Material examined.

Ambrysus has been organized into five subgenera (La Rivers 1965, Nieser et al. 1999).

Picrops differs from the remainder of the genus Ambrysus in a much greater suite of characters than was originally presented by La Rivers. Both sexes of Picrops have four or more distal comb rows of spines on the hind tibia (three or fewer in Ambrysus). The midline of the abdominal sternum is clothed with a heavy band of elongate hairs on segments III–VIII in males and III–VII in females, similar in appearance to the thick mid-ventral band of hairs in species of Laccocorinae and more profuse than in most species of Ambrysus . The accessory genitalic process of male tergum VI is absent, whereas it is present in most species of Ambrysus . Mediotergite VII in males is enlarged and bears a lateral process on each side (sometimes absent on the left side); no species of Ambrysus has such modification of mediotergite VII. The pseudoparameres of tergum VIII are reduced or absent, whereas the condition of these structures has recently been shown to be informative at the species complex or species level in Ambrysus (Reynoso-Velasco &amp; Sites 2016a, b). The parameres are asymmetrical and wrap over the phallosoma, whereas they are symmetrical and generally lie to the sides of the phallosoma in Ambrysus . The femora and tibiae are exceptionally slender for this family. The lateral margin of the eye appears as a sharp point, hence the name Picrops . The dorsal surface is a mottled pattern of dark and light brown with hints of rose on the head, pronotum, forefemora, and connexiva. This genus is among the most dorsoventrally flattened naucorids. The asymmetrical parameres and modified mediotergite VII are autapomorphies of Picrops within Ambrysini . These features together clearly distinguish members of this subgenus from all other species of Ambrysus . Thus, we elevate the subgenus Picrops to full generic rank.</p></div>	https://treatment.plazi.org/id/03BB115251239B6C479FFA82FDA4FF49	Public Domain	No known copyright restrictions apply.

This species was known from the Guiana Shield countries of Brazil, French Guiana, Guyana, and Suriname (Nieser 1975). While examining many specimens from these countries in addition to Bolivia, Peru, and Venezuela it became evident that this genus is not monotypic. Differences in the female subgenital plate and male mediotergite VII were apparent. Female subgenital plates exhibited two forms: one with straight, convergent lateral margins and no tubercle (Fig. 18), the other with sinuate lateral margins and a median tubercle (Fig. 19). Variation in expression of male mediotergite VII included shape-related differences in the right lateral process and presence/ absence and shape differences in the left process. More specifically, the right process is always present and varied from elongate and narrow (Figs. 27, 28) to truncate and as wide as long. When present, the left process varied from acuminate (Fig. 27) to a short, rounded production (Fig. 28). We found multiple character states of mediotergite VII within populations; thus, this character apparently is variable and not taxonomically informative. However, the female subgenital plate condition was consistent within populations and is the only character we found that was able to distinguish between species.</p><p>The holotype and two paratypes of P. usingeri are from Beruri in Beruri municipality near Manaus in the state of Amazonas, Brazil (Fig. 20, green dot). Because the holotype and paratype in the Snow Museum in Kansas (SEMC) are both males, they cannot be determined to species because the female subgenital plate is the only reliable diagnostic character that we have found. However, the topotypic paratype in the Essig Museum at Berkeley (EMEC) is a female; it lacks a tubercle and has straight, convergent margins (Fig. 18), thereby establishing this as the form of P. usingeri . A non-topotypic female paratype from Suriname, housed at EMEC, has a tubercle on the subgenital plate and represents a second species (see below).</p><p>Picrops usingeri is widespread throughout much of the Amazon Basin and into the Guiana Shield (Fig. 20). Because females are required for identification, samples represented by only males are marked on the map with white circles (Fig. 20); however, specimens from the localities south of the Guiana Shield, especially those in Bolivia, Peru, and Rondônia, probably are P. usingeri . This is the first record of P. usingeri in Venezuela, and of Picrops in Bolivia and Peru. At Sipaliwini in Suriname, P. usingeri was collected with Ambrysus stali La Rivers and Limnocoris burmeisteri De Carlo.</p><p>Published records.

Both species of Picrops are easy to recognize to the generic level by their general physiognomy. They are among the most dorsoventrally flattened naucorids with among the most slender legs. These together with the peculiar angular head, pronotal shape, and mottled coloration makes this genus recognizable at a glance. Distinguishing between the species requires female specimens, as is the case with certain groups of Ambrysus (e.g., A. hybridus species group [Reynoso-Velasco &amp; Sites 2016b]). The female subgenital plate of P. tuberculatus has a prominent, hairless, sometimes lightly pigmented tubercle on the midline near the posterior margin (Fig. 19). In addition, the lateral margins of the subgenital plate are sinuate. In contrast, P. usingeri females lack the tubercle, the lateral margins of the subgenital plate are straight and convergent (Fig. 18), and the posterior margin is usually straight, although in some specimens it can be slightly notched or concave. In males, the right process of mediotergite VII was always digitate in specimens of P. tuberculatus, whereas its condition in P. usingeri was either digitate or short, wide, and truncate. The process of the left side for each species could be acuminate, produced, or rounded. Populations of each species were found to include male specimens with more than one condition of mediotergite VII. We also found variation in male genitalia in the shapes of the pygophore and parameres; however, the variation was not consistent geographically and multiple conditions were present within populations. As such, we considered the male characteristics to be intraspecifically variable and not taxonomically reliable; males must be identified by association with contemporaneously collected females.</p><p>Habitat description. The habitat of this species is very similar to that of Picrops usingeri: leafpacks in relatively small, shallow, slowly-moving, sandy-bottomed streams running through moist tropical forest (Fig. 29). Adults and nymphs can be found among masses of intact, dead leaves floating on the surface. We collected P. tuberculatus syntopically with Ambrysus stali La Rivers and A. partridgei De Carlo at or adjacent to the type locality.</p><p>Discussion. The only known congener, Picrops usingeri, occurs widely throughout much of the Amazon Basin and Guiana Shield, whereas P. tuberculatus n. sp. apparently is restricted to the Guiana Shield. Distribution patterns such as this with a widespread species and congeners with restricted ranges are common in other groups of aquatic Heteroptera.</p><p>Etymology. The species is named for the median tubercle on the female subgenital plate.</p><p>Repositories. The holotype is deposited in the Muséum National d'Histoire Naturelle—Paris (MNHN). Paratypes will be deposited in the University of Missouri (UMC), University of Kansas (SEMC), University of California—Berkeley (EMEC) and the United States National Museum of Natural History (USNM).</p><p>Type material examined.
