FIGS 483-492

(483-485) Ochthephilus merkli sp. n.; aedeagus (483), female ringstructures (484-485). (486-488) O. kleebergi sp. n.; aedeagus (486), female ringstructures (487-488). (489-492) O. szarukani sp. n.; aedeagus (489), spermatheca (490), female ringstructures (491-492). Scale bar = 0.07 mm for 487-488, 490, 0.1 mm for 491-492, 0.14 mm for 483-486, 0.17 mm for 489.

DESCRIPTION: Forebody as in Fig. 560. Measurements (n=10): HW = 0.66 (0.64-0.68); TW = 0.60 (0.57-0.61); PW = 0.74 (0.69-0.79); SW = 1.02 (0.95-1.07); AW = 1.08 (1.01-1.19); HL = 0.51 (0.48-0.55); EL = 0.24 (0.23-0.25); TL = 0.105 (0.10-0.11); PL = 0.61 (0.57-0.63); SL = 1.16 (1.10-1.20); SC = 1.04 (0.98-1.08); FB = 2.36 (2.22-2.44); BL = 4.41 (4.02-4.79) mm. Whole body very dark brown, head darkest, 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 shallow and very fine punctation on head and pronotum, but distinct and dense coriaceous microsculpture on interspaces everywhere; elytral punctation fine, shallow but dense, setation more dense than is closest congeners. Pubescence on elytra very dense, strong and very 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. 586. Clypeus 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 slightly 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, getting inconspicuous anteriorly with pronotal corners strongly curved in ventral direction. Posterior pronotal angles well-formed, just slightly obtuse-angled, sides in posterior 1/3 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 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 stronger coriaceous/colliculate microsculpture, fading on elevated parts, stronger in impressions, on pronotum microsculpture slightly stronger and more even. Punctation on head fine, more dense on 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 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 with more coarse spiniform processes. Tergite VIII basal edge evenly arched, without

FIGS 493-497

Ochthephilus indicus sp. n.; head and pronotum (493), side of head (494), antenna (495), elytra and base of abdomen (496), left side of tergite VII (497). All SEM, dorsal views. Scale bar = 0.17 mm for 494, 0.2 mm for 497, 0.4 mm for 493, 0.45 mm for 496, 0.5 mm for 495.

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. 489. Spermatheca as in Fig. 490, female ringstructures as in Figs 491-492.

ETYMOLOGY: The species is named after Dr. István Szarukán, professor at the University of Debrecen, my teacher of applied entomology when it was still Agricultural University and one of the key figures in my starting a career in Entomology.

COMPARATIVE NOTES: From the similarly large black species (the pair of O. ritae and O. tichomirovae , plus O. kleebergi ) it can be separated by its different pronotal shape (similar to that of O. indicus in Fig. 493). From the other black species outside the O. monticola complex, O. zerchei , it is distinguishable by size.

DISTRIBUTION: All known specimens are from the Chinese province of Sichuan .

BIONOMICS: Specimens were collected at streambank, from moss and gravel, also by sifting moist to wet moss and debris among low shrubbery.
