Wholebodyverydarkbrown, headdarkest, almost black, elytra sometimes very slightly lighter but still dark brown, scutellar area to shoulders black. Antennae, mouthparts and legs dark brown, antenna blackish, tarsi and both ends of tibiae occasionally somewhat lighter. Body with greasy lustre due to rather fine and shallow punctation on head and pronotum, but distinct coriaceous FIGS 498-508

microsculpture on interspaces everywhere; elytral punctation fine, shallow but rather dense. Pubescence on elytra short, strong and regularly spaced, in contrast with somewhat less conspicuous setation of head and pronotum: with rather fine and dense setae. Abdominal tergites with setae finer than 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 without conspicuous setae. Last tarsomere with a few setae only.

Forebody. Antenna as in Fig. 482. Clypeus almost impunctate (colliculate microsculptured), trapezoid, corners rounded, anterior edge gently arched; separated by impressed transversal line (frontoclypeal suture) across a shinier area. Vertex with two oblique impressions almost joining in a v-shape in the middle; midlongitudinal line very slightly elevated. Temples slightly bulging, evenly curved, barely longer than half of eye length. Neck separated by a gently impressed line differing by lack of setation and punctation but with similarly strong microsculpture. Posterior pronotal angles well-formed, just slightly obtuse-angled, sides in posterior 1/3 very gently concave. Pronotum with a narrow marginal bead, getting inconspicuous anteriorly with pronotal corners strongly curved in ventral direction. '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 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 and pronotum with strong coriaceous microsculpture providing a greasy lustre. Punctation very deep and pronounced, interspaces slightly less than diameters. Elytra with twice as coarse punctation but with indistinct microsculpture, as a result elytra much more shiny.

Abdomen. Compared to forebody, abdomen with much more sparse, shallow, less distinct punctation except basal ridge and a narrow transversal furrow posteriad, not too strong coriaceous microsculpture. Tergite VII posterior margin with palisade fringe broadened in middle with more coarse spiniform processes. Tergite VIII basal edge evenly arched, without 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. 467, paramere from side view as in Fig. 468. Spermatheca as in Fig. 469, female ringstructures as in Figs 470-471.

ETYMOLOGY: The species is named after Anna L. Tichomirova, one of very few female staphylinidologists who had great influence despite her short life.

COMPARATIVE NOTES: From the most closely related species, O. ritae , it is virtually indistinguishable externally, but the two have different genitalia. The features separating O. tichomirovae from O. szarukani and O. kleebergi are listed under FIGS 509-513

Ochthephilus kleebergi sp. n.; head and pronotum (509), side of head (510), antenna (511), elytra and base of abdomen (512), left side of tergite VII (513). All SEM, dorsal views. Scale bar = 0.17 mm for 510, 0.19 mm for 513, 0.4 mm for 509, 0.5 mm for 511-512.

O. ritae . From the other black species outside the O. monticola complex, O. zerchei , it is distinguishable by size.

DISTRIBUTION: Known from Kashmir, N-India, Nepal and the Chinese provinces of Sichuan and Yunnan.

BIONOMICS: Specimens were collected from under stones at riverbank, gravelbank of river.
