description: 6. Ocypus (Pseudocypus) fusciculminis sp. nov.
(Figs. 6-1, 6-2)
Type locality: CHINA, Sichuan Province, southwest of Jiulong County.
Type material. Holotype male, CHINA: Sichuan Province: southwest of Jiulong County, 3675 m, grassy marshland and Cyclobalanopsis glauca shrub, pitfall traps, 10–13.VII.2001, coll. Xiaodong Yu & Hongzhang Zhou (IZ-CAS). Paratypes: CHINA: Sichuan Province: 4 males, same data as holotype (IZ-CAS); 1 male, north of Jiulong County, 3750 m, grassy marshland, pitfall traps, 11–14.VII.2001, coll. Xiaodong Yu & Hongzhang Zhou (IZ-CAS).
Measurements. Body length: 14.7–19.3 mm. CL: 0.55; EL: 2.33; ELS: 0.96; EW: 2.88; HL: 2.54; HW: 2.93; PO: 1.42; PL: 2.91; PW: 2.59.
Description. Medium to small sized species. Body slender, black, with elytra paler; maxillary and labial palpi brown; antennae dark brown, gradually becoming paler towards apex; legs brown; protibia and protarsus covered with dense brown pubescence; pubescence of dorsal side of body uniformly brownish-black.
Head of rounded quadrangular shape, with curved lateral sides, wider than long (ratio 1.15). Eyes small and slightly protruding, considerably shorter than tempora (ratio 0.38) in dorsal view. Punctation and pubescence on dorsal surface of head moderately dense and fine, puncture intervals distinctly larger than diameters of punctures; punctation gradually becoming sparser toward clypeus; impunctate midline indistinct; interspaces between punctures with fine and dense microsculpture. Gular sutures distinctly separated, and gular become strip-shaped in midsection, distinctly dilated toward apex. Antenna moderately long, segment 3 about as long as segment 2, segments 4 and 5 longer than wide, segments 6 to 10 about as long as wide to slightly wider than long; segment 11 shorter than two preceding segments combined. Pronotum vaguely longer than wide (ratio 1.12), with almost parallel lateral sides; narrow marginal groove disappearing downwards at about half of pronotal length; disc with entire and relatively distinct impunctate midline; punctation and pubescence on disc sparser than that on dorsal surface of head. Pronotal hypomeron lacking microsetae. Scutellum finely punctate and setose on entire surface. Elytra short, wider than pronotum, distinctly depressed at base, slightly dilated posteriad; elytral length shorter than pronotum along midline, with a ratio of 0.32 along suture and a ratio of 0.79 along sides; elytral punctation much finer and denser than head disc, combined with very dense microsculpture. Wings markedly reduced. Abdominal tergite 2 with punctures and pubescence on entire surface, gradually becoming sparser toward basal parts; all visible abdominal tergites finely and densely punctate, punctation gradually becoming sparser toward apex of abdomen; no yellowish tomentose pubescence present on visible tergites 4 and 5.
Male. Sternite 8 with obtusely triangular medioapical emargination (Fig. 6-2 H). Sternite 9 relatively elongate, apical emargination deep and subacute; tapered basal portion rather short (Fig. 6-2 G). Tergite 10 relatively narrow, with subacute apex, moderately setose (Fig. 6-2 E). Aedeagus simple and elongate, shaped as in Figs. 6-1 B, C, 6-2 B–D; apical portion of median lobe knife shaped, distinctly asymmetrical (Fig. 6-2 F); paramere lingulate, with obtusely rounded apex; sensory peg setae on underside of paramere arranged along lateral sides, not numerous (Figs. 6-1 D, 6-2 A).
Female. Unknown.
Distribution. Ocypus fusciculminis sp. nov. is at present known only from Jiulong County in southern Sichuan Province.
Notes. Ocypus fusciculminis sp. nov. can be distinguished from congeners, by its pale brown antenna and legs and characters of the aedeagus.
Etymology. The specific epithet, fusciculminis, is from Latin words " fuscus " (brown colored, to indicate the special color of the legs and antennae) and " culmen " (culminis, tip, top).
