FIGS 389-394

TergitesVIII; Ochthephilusnitidus (Cameron) (389), O. schuelkei sp. n. (390), O. nepalensis (Scheerpeltz) (391), O. incognitus sp. n. (392), O. enigmaticus sp. n. (393), O. championi (Bernhauer) (394). Scale bar = 0.1 mm for 391, 393, 0.11 mm for 389-390, 0.13 mm for 394.

REDESCRIPTION: Forebody as in Fig. 550. Measurements (n=10): HW = 0.65 (0.62-0.69); TW = 0.60 (0.58-0.63); PW = 0.77 (0.74-0.80); SW = 1.00 (0.96-1.06); AW = 1.09 (1.02-1.20); HL = 0.51 (0.48-0.54); EL = 0.20 (0.18-0.21); TL = 0.11 (0.10- 0.12); PL = 0.63 (0.60-0.64); SL = 1.15 (1.06-1.18); SC = 1.05 (0.96-1.10); FB = 2.36 (2.24-2.50); BL = 4.45 (4.00-4.80) mm. Head, pronotum and abdomen dark brown with an occasional reddish tint. Elytra reddish medium to dark brown, darker around scutellum to shoulders and in a transversal stripe at elyral apex. Legs, mouthparts and antennae reddish medium brown, but antennae (except basal articles) sometimes dark brown. In some specimens mid-tibiae dark brown but femora (except apex) remaining dark. Body moderately lustrous due to not so deep punctation on head and pronotum, but distinct coriaceous microsculpture covering interspaces; very short but strong elytral setation. Pubescence on elytra short but strong and rather dense (regularly spaced), in contrast with much less conspicuous setation of head and pronotum: with rather fine and moderately dense setae. Abdominal tergites with setae just as thick as elytral ones but much longer, especially at apices of tergites and adjacent to laterosternites. Head anteriad eyes and near inner posterior margin of eye with stronger and much longer bristles, as well as pronotal margin; at middle of tibiae with darker bristles. Elytral apex with occasional stronger and longer setae near sutural corners. Last tarsomere with a few setae only.

Forebody. Antenna as in Fig. 425. Clypeus (Fig. 388) sparsely punctate (colliculate microsculptured), trapezoid, corners rounded, anterior edge gently arched; separated by impressed transversal line (frontoclypeal suture) across a shinier area. Supraantennal prominences well developed, feebly separated from clypeus/vertex by impressions. Vertex with oblique impressions in middle almost joining in V-shape. Temples bulging, evenly curved, little shorter than half of eye length. Neck separated by an impressed transversal groove, microsculpture much stronger than on head, with transverse cells, no setation. Pronotum with a narrow marginal bead, visible to anterior pronotal corners. Posterior pronotal angles well-formed, just slightly obtuse-angled, sides in posterior 1/3 very gently concave. 'Anchor' fully formed, longitudinal midline as a slightly elevated, impunctate, weakly microsculptured line, parallel to this line two gentle, semi-longitudinal elongate elevations in anterior half of disc. In corners of anchor feeble, oblique impressions directed outwards, in middle at sides of midline two smaller impressions. Elytra (Fig. 411) slightly broadening posteriorly, sutural corners narrowly rounded; apical sides slightly oblique and in inner halves more or less straight. Elytral surface rather even with two shallow, very elongate impressions behind scutellum. Head with fine coriaceous/colliculate microsculpture, fading on elevated parts, stronger in impressions, on pronotum microsculpture slightly stronger and more even. Punctation on head more dense on confined posterior part and sides, on pronotum more evenly spaced, very fine, average interspaces much larger than puncture diameters; elytral punctation more even and regularly spaced, average interspaces (with indistinct coriaceous microsculpture) about as puncture diameters, punctures discrete. Elytral apex without conspicuous setae.

Abdomen. Compared to forebody, abdomen with much more sparse, finer, less distinct punctation, microsculpture on tergal apices fine coriaceous with moderately transverse cells. Tergite VII posterior margin with palisade fringe broadened in middle (Fig. 412) with more coarse spiniform processes. Tergite VIII basal edge evenly arched, with small concavity in middle of basal sclerotized band; apical edge with sinuate (protruding) corners, and broad, moderately deep emargination in between. Sternite VIII with rounded apical corners, apex in males shallowly concave laterally, gently sinuate in middle; in females slightly more sinuate (convex) in middle. Tergite X unmodified, apex very slightly wider in males than in females. Aedeagus as in Fig. 413. Female ringstructures as in Figs 414-415.

COMPARATIVE NOTES: This species is superficially similar to O. sericinus (in fact one of the paratypes of O. ketmenicus has turned out to be O. sericinus ), similarly sized and coloured. Attention to details (lack of antennal modification, different elytral setation, lack of small incisions at apex of tergite X), however, reveals its identity.

DISTRIBUTION: The species is so far known from Kazakhstan, Kyrgyzstan and

Tajikistan.

BIONOMICS: Specimens were collected under stones, boulders, debris alongside stream.
