DESCRIPTION: Forebody as in Fig. 537. Measurements (n=10): HW = 0.52 (0.50-0.53); TW = 0.47 (0.45-0.48); PW = 0.57 (0.52-0.59); SW = 0.71 (0.67-0.74); AW = 0.72 (0.68-0.76); HL = 0.37 (0.38-0.41); EL = 0.17 (0.16-0.18); TL = 0.08 (0.07- 0.09); PL = 0.44 (0.42-0.45); SL = 0.88 (0.84-0.92); SC = 0.80 (0.78-0.84); FB = 1.75 (1.66-1.90); BL = 3.10 (2.72-3.36) mm. Head, pronotum and abdomen blackish dark brown with slight reddish tint, head sometimes even darker, but elytra conspicuously light, reddish medium brown, scutellar area (variously broadly) darker, somewhat blackish. Legs medium brown, antennae and mouthparts dark brown. Body with greasy lustre mostly due to elytral setation plus forebody punctation and microsculpture. Pubescence rather fine and moderately dense, shorter and stronger (regularly spaced) on elytra, abdominal tergites with finer and longer setae, especially adjacent to laterosternites. Head anteriad eyes and near inner posterior margin of eye with stronger and darker bristles, as well as pronotal margin and middle of tibiae. Elytral apex without conspicuous setae. Last tarsomere with a few setae only.

Forebody. Antenna as in Fig. 227, antennomere 6 shorter and less wide than neighbours (articles 5 and 7). Clypeus (Fig. 252) almost impunctate (colliculate microsculptured), trapezoid, corners rounded, anterior edge gently arched; separated by an impressed transversal line (frontoclypeal suture) across a shinier area. Supraantennal prominences well developed, feebly separated from clypeus/vertex by longitudinal impressions. Vertex with two deeper impressions with two larger, setiferous punctures in them. 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 2/3 very gently concave/bisinuate. '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. 253) slightly broadening posteriorly, sutural corners narrowly rounded; apical sides slightly oblique and in inner halves gently convex. Elytral surface rather even with two shallow, very elongate impressions behind scutellum. Head with fine coriaceous/colliculate microsculpture, very strongly fading on all elevated parts, leaving surface predominantly shiny, on pronotum even more expressed. Punctation on head sparse and mostly fine, average interspaces 2-3x puncture diameters, pronotal punctation extremely fine but distinct, average interspaces 3x puncture diameters; elytral punctation more even and regularly spaced, average interspaces (with indistinct coriaceous microsculpture) about as puncture diameters, punctures discrete.

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 unmodified in middle (nearly uniform breadth). Tergite VIII (Fig. 392) 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. 369, inner sclerites as in Figs 370-371. Female ringstructures as in Figs 372-373.

ETYMOLOGY: The latin name of this species refers to this taxon remaining unrecognized among similar congeners for a long time.

COMPARATIVE NOTES: This is an unusually light coloured species in the O. omalinus group, and by this distinguishes it from all other (possibly co-occuring) group mates in the region, besides different genital structures.

DISTRIBUTION: Currently only known the Ozarks in the USA, very likely endemic to this area.

BIONOMICS: Specimens were collected from under stones and in sand on streambank.

ETYMOLOGY: The species is named after Jakov D. Kirschenblatt who first recognized this new species under the name 'alticola' (unpublished). Being aware of the different spellings required by modern transcription rules, when naming the species after him I deliberately follow the one that Kirschenblatt himself used on his labels and in his writings.

COMPARATIVE NOTES: A small species; very much unlike other members of the

O. omalinus group with relatively small eyes and large temples.

DISTRIBUTION: Currently only known from China (around the Plateau of Tibet and the Dzhungarian Basin).

BIONOMICS: No bionomical data of any kind are recorded for the few known specimens, but it is probable that they were collected on bank of water.

Head anteriad eyes and near inner posterior margin of eye with stronger and darker bristles, as well as pronotal margin and middle of tibiae. Elytral apex without conspicuous setae. Last tarsomere with a few setae only.

Forebody. Antenna as in Fig. 380, antennomere 6 (Fig. 357) shorter and less wide than neighbours (articles 5 and 7). Clypeus (Fig. 324) 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 (Fig. 352) 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 2/3 very gently concave/bisinuate. '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. 325) slightly broadening posteriorly, sutural corners narrowly rounded; apical sides slightly oblique and in inner halves gently convex. 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 sparse, mostly confined to posterior part and sides, on pronotum more evenly spaced, 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.

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 (Fig. 386) with palisade fringe unmodified in middle (nearly uniform breadth). Tergite VIII (Fig. 391) 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. 374, inner sclerites as in Figs 375-376. Female ringstructures as in Figs 377-378.

COMPARATIVE NOTES: From other members of the O. omalinus group can be separated by the inner sclerites of the aedeagus: the secondary sclerite is so large that it almost reaches the size of the primary sclerite; in most other related species much smaller, except in O. andalusiacus . The specimens in the main range of the Himalaya have much more slender/elongate antennae compared to the ones from China, but male genitalia are identical.

DISTRIBUTION: The species is so far known from the High Himalayas (from Kashmir through Nepal and North India to Sikkim) and the Chinese province of Sichuan.

BIONOMICS: Specimens were collected from gravelbank of a river and from under large stones at a mountain river.

Body dark brown, head and pronotum sometimes darker, blackish. Antennae, mouthparts and legs also dark brown, blackish. Body with above average lustre mostly due to short elytral setation and sparse forebody punctation with large, smoother interspaces. Pubescence rather fine and moderately dense, shorter and stronger (regularly spaced) on elytra, abdomen with long but rather sparse setae. Head and pronotum with sparser than average setae (also stronger than usual). Head anteriad eyes and near inner posterior margin of eye with stronger and darker bristles, as well as pronotal margin and middle of tibiae. Elytral apex without conspicuous setae. Last tarsomere with a few setae only.

Forebody. Antenna as in Fig. 577, antennomere 6 shorter and less wide than neighbours (articles 5 and 7). Clypeus almost impunctate (microsculpture fading colliculate), 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 2/3 insignificantly concave/bisinuate.

In corners of anchor feeble, oblique impressions directed outwards, in middle at sides of midline two smaller impressions. Elytra slightly broadening posteriorly, sutural corners narrowly rounded; apical sides slightly oblique and in inner halves gently convex. 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 sparse, mostly confined to posterior part and sides, on pro- notum more evenly spaced, 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.

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 unmodified in middle (nearly uniform breadth). Tergite VIII (Fig. 389) 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. 319, inner sclerites as in Figs 320-321. Female ringstructures as in Figs 322-323.

COMPARATIVE NOTES: This species stands out by its shinier head and pronotum (with faded microsculpture between scattered punctures) and thereby can be distinguished from the other members of the O. omalinus group in the region.

DISTRIBUTION: The species is so far known from Kashmir, N-India and Nepal.

BIONOMICS: Very little bionomical data exist for this apparently frequent species, some specimens were sifted from wet mosses.
