Head with reddish clypeus, frons and vertex darkened, brown blackish; pronotum brown blackish, laterally broadly testaceous; elytra brown with broad, irregularly shaped, basal orange band reaching suture. Pronotum with short longitudinal strioles laterally. Each elytron with six complete discal striae and one submarginal stria: all striae beginning at base; stria 1 longest, ending close to apex; striae 2–5 somewhat shorter, ending subapically, even striae generally shorter than odd striae; stria 6 ending at apical fourth; submarginal stria long, beginning before elytral mid-length and ending at apical fourth (Fig. 2). Median lobe of aedeagus in lateral view sickle-shaped, narrowing in apical fourth to skewed, dorsally slightly extended apex; dorsal and ventral side of apical part straight (Fig. 31). Parameres moderately broad, ‘C’-shaped; apex short and broad; apical lobes long, club-shaped (Fig. 32). Female similar to male, strioles on pronotum more numerous. Comments on the classification. Guignot (1952) synonymized C. chinensis with C. japonicus Sharp, 1884 based on the drawing of median lobe of the latter species by Balfour-Browne (1947). However, the dissection of the holotype of C. chinensis revealed that the genitalia of both taxa are quite different (see Figs 31 and 39). Therefore, we reinstate C. chinensis as a valid species. Copelatus collocallosus was described twice, based on a single teneral female (Fig. 3); the first brief description (Falkenström 1932) was subsequently supplemented with a differential diagnosis from C. chinensis: pale colouration, different body shape, indistinct punctation, small number of extremely short strioles on the pronotum, rather long submarginal stria (Falkenström 1933). Gschwendtner (1939) was the first who considered C. collocallosus as a synonym of C. chinensis; however, probably based on synonymy of C. chinensis with C. japonicus by Guignot (1952), Satô (1982) mentioned C. collocallosus as a synonym of C. japonicus – a state which was largely accepted until now (cf. Nilsson 1995, Nilsson & Hájek 2022a). However, our study confirmed specific status of C. chinensis (see above). Further, in accordance with Gschwendtner (1939), the comparison of the C. collocallosus holotype with the extensive material of C. chinensis showed that both taxa are morphologically indistinguishable, including identical punctation of dorsal surface, presence of strioles on pronotum and length of elytral striae. Therefore, we consider C. collocallosus as a junior subjective synonym of C. chinensis, although we are aware that the identity of C. collocallosus is doubtful as the teneral female does not possess characters usable for species identification – the species of the C. japonicus complex are recognisable predominantly based on male genitalia. Anyway, the synonym of C. chinensis and C. collocallosus also seems reasonable from a biogeographical point of view: C. chinensis is widely distributed in Central China, and its type locality in Hubei lies only ca. 100 apart from the border of Chongqing Municipality (a presumed type locality of C. collocallosus). Collection details. In Tianmushan (Zhejiang), Copelatus chinensis was collected in number in exposed side pool of a river with sandy bottom (Fig. 71); few specimens were found also in shaded forest puddle with muddy bottom. Distribution. Central and eastern China (Hubei, Hunan, Shandong, Sichuan or Chongqing, and Zhejiang provinces) (Fig. 81).Published as part of Jiang, Zhuo-Yin, Zhao, Shuang, Yang, Zhen-Yu, Jia, Feng-Long & Hájek, Jiří, 2022, A review of Copelatus Erichson, 1832 of Mainland China, with description of ten new species from the japonicus complex (Coleoptera: Dytiscidae: Copelatinae), pp. 251-295 in Zootaxa 5124 (3) on pages 253-254, DOI: 10.11646/zootaxa.5124.3.1, http://zenodo.org/record/641069

Gyrinus (Oreogyrinus) colombicus Regimbart 1883
No full textGyrinus (Oreogyrinus) colombicus Régimbart, 1883 (Fig. 47) Gyrinus colombicus Régimbart, 1883: 180 (original description). Gyrinus (Oreogyrinus) colombicus: OCHS (1953): 184 (new status). Type locality. ‘Colombia’. Typematerial examined. SYNTYPE: J, ‘Colombie [beige label, handwrittenblack ink]’ ‘MUSEUM PARIS / COLL. MAURICE REGIMBART / 1908 [green label, typed black ink]’ ‘R. Mouchamps vid., 1955 / GYRINUS / colombicus Rég / [white label, R. Mouchamps vid., 19- typed black ink, -55 GYRINUS colombicus Rég. Handwritten black ink]’ (MNHN). Other material examined. VENEZUELA: without additional data (1 spec. BMNH). Non-Venezuelan material examined. COLOMBIA: ‘Colombie’, Sharp Col. 1905-313 (1 spec. BMNH). SUCRE: Cuenca (1 spec. BMNH). Without locality: Sharp Col. 1905-313 (2 spec. BMNH). Diagnosis. Body form oval, in lateral view strongly convex; pronotal disc with transverse creased strongly impressed, laterally with sparse wrinkles; elytral disc of female with at most intervals I–II non-reticulate, III–X strongly reticulate, XI non-reticulate; female elytral striae VI–IX sulcate, only VII–IX strongly so; elytrallateral marginweakly interrupted before apex; metanepisternal ostiole present; aedeagus (Fig. 47) with median lobe evenly narrowed for 2/3 length, weakly expanded towards apex in apical 1/3, apex broadly rounded; parameres truncate apically. Gyrinus colombicus is most similar to G. venezolensis having a relatively weakly wrinkled pronotum. The strongly reticulate female elytra of G. colombicus should easily prevent confusion with females of both G. venezolensis and G. vinolentus sp. nov. as the reticulation covers nearly the entire elytron (at least to interval II), whereas in G. venezolensis and G. vinolentus sp. nov. females the reticulation is present up to at most interval IV. The aedeagus (Fig. 47) will easily distinguish males of G. colombicus from both G. venezolensis and G. vinolentus sp. nov. Redescription. Size. Female length = 5.5– 6.0 mm, width = 3.5 mm; male length = 4.5–5.0 mm, width = 3.0 mm. Habitus. Body form evenly oval, attenuated anteriorly and posteriorly, slightly more so posteriorly, widest point just posteriad of humeral region; in lateral view dorsoventrally strongly convex, greatest convexity posterior to scutellar region, evenly depressed anteriorly and posteriorly. Coloration. Dorsally, head, pronotum, elytra black, with blue reflections; laterally reflections bronzy yellow and green, especially in females whose elytral lateral reticulation appears strongly bronzy green. Venter overall darkly colored; mouthparts, ventral surface of antennal pedicel, hypomeron, elytral epipleuron, mesoventrite medially, mesocoxae, and ultimate abdominal ventrite lighter in color – reddish brown to darker orange yellow; legs yellow in color; remainder of venter dark brown to black. Sculpture and structure. Pronotum ofboth sexes with broad riffled lateral margins; pronotal disc laterally weakly wrinkled, wrinkles present anteriorly and associated with pronotal transverse impressed line, wrinkles also present posteriorly near posterior margin of pronotum. Female elytra with striae I–IV non-sulcate, elytral striae Vweakly sulcate medially, VI slightly more sulcate medially, VI–IV strongly sulcate posteriad of humeral region with linear punctures medially, stria X non-sulcate, stria XI strictly marginal. Female elytral disc nearly entirely reticulate with at most intervals I–II free of reticulation, XI never with reticulation, reticulation composed of scale-like sculpticells. Male elytra with striae I–VII non-sulcate; VIII–IX weakly sulcate just posterior to humeral region, ending before apical 1/3 of elytron; stria X non-sulcate; stria XI strictly marginal. Male elytral disc with intervals I–XI without reticulation. Elytra ofboth sexes withlateralmargins weakly interrupted inapical 1/5 by minor swelling; elytral apex truncate to weakly rounded. Metanepisternal ostiole small. Male genitalia (Fig. 47). Aedeagus with median lobe narrow, shorter than parameres, attenuated towards apex in basal 2/3, in apical 1/3 weakly laterally expanded towards apex, apex broadly rounded, medially weakly raised; in lateral view median lobe thick, strongly dorsally curved; parameres with apex strongly truncate. Variability. Of the few female specimens examined, there was variability in the extant of the reticulate region of the elytra. Two of the three specimens examined had the reticulation extending to elytral interval II, while the third had the reticulation extending all the way onto interval I, reaching the elytral sutural border in areas. Habitat. Unknown Distribution. Colombia. Discussion. This species is primarily known from historical specimens from Colombia and ‘Venezuela’, often withlittle orno further specific localityinformation (RÉGIMBART 1907, OCHS 1953). In his first treatmentof the Venezuelan Gyrinidae, OCHS (1953) included G. colombicus stating the species is likely to be found in western Venezuela. However, he only examined specimens from Colombia, and believed most of the historical Colombian specimens to be from Bogotá (OCHS 1953). In our study, only a single historical specimen was examined with the locality of ‘Venezuela’ from the BMNH, and the species was not recollected during the Venezuelan aquatic insect survey, despite multiple sampling localities in the western Venezuelan Andes. It seems likely the historical specimens from ‘Venezuela’ are in error, and that the species does not truly occur in Venezuela. For this reason, we did not extensively treat G. colombicus, but to aid in its identification, should it be found in Venezuela in the future, we provide a redescription of the specimens examined and an image of the aedeagus of a syntype in the MNHN.Published as part of Gustafson, Grey T. & Short, Andrew E.
