Head of rounded quadrangular shape, with obtuse to rounded posterior angles, usually vaguely dilated posteriad, wider than long (ratio 1.22), eyes moderately large, rather flat, tempora longer than eyes from above (ratio 1.80); dorsal surface of head finely and densely punctate, interspaces between punctures on disc distinctly narrower than diameters of punctures, punctation gradually becoming denser toward posterior and lateral margins, less dense toward and on clypeus, interspaces between punctures without microsculpture; impunctate midline absent, V-shaped front portion of epicranial suture present in most specimens; dorsal side of neck with punctation finer and denser than that on head. Antenna moderately long, segment 3 longer than segment 2 (ratio 1.25), segments 4 to 8 slightly longer than wide, becoming gradually shorter, segments 9 and 10 about as long as wide, last segment short, considerably shorter that two preceding segments combined. Pronotum slightly longer than wide, subparallelsided or slightly narrowed posteriad, moderately convex, narrow marginal groove disappearing downwards just in front of middle of pronotal length; impunctate narrow midline usually apparent on posterior third of pronotal length, or only in front of posterior margin of pronotum; punctation on disc fine and very dense, appreciably finer and denser than that on disc of head. Pronotal hypomeron without microsetae. Scutellum densely punctate and dark brownish pubescent, with patch of black tomentose pubescence at apex. Elytra rather short, parallelsided to vaguely dilated posteriad, at suture distinctly shorter (ratio 0.68), at sides somewhat shorter than pronotum at midline (ratio 0.82); punctation very fine and very dense, granulose. Wings each reduced to short, nonfunctional stump. Abdomen with fifth visible tergite lacking pale apical seam of palisade setae; tergite 2 (anterior to first visible tergite) entirely punctate and pubescent; all tergites evenly, densely and very finely punctate; interspaces with very fine, dense, transversely meshed microsculpture. Male. Sternite 8 with moderately wide and deep triangular medioapical emargination. Genital segment with sternite 9 with very narrow basal portion, apical portion gradually narrowed toward minutely emarginate apex (Fig. 17). Tergite 10 moderately wide, with narrowly arcuate apex (Fig. 18). Aedoeagus (Figs. 19–21) of quite characteristic shape; median lobe in ventral view highly asymmetrical, with right portion conspicuously dilated and extended at side close to paramere into short, narrow apical portion with narrowly arcuate apex; apical half of paramere in ventral view markedly turned and twisted laterad, with subtruncate apex; underside of paramere lacking sensory peg setae, apical setae minute, situated as in Fig. 21. Female. Tergite 10 of genital segment relatively narrow, apical portion gradually, evenly narrowed toward acute apex (Fig. 22). Length 17.0–19.0 mm. <b>Etymology.</b> The species is named in honor of the outstanding coleopterist and my dear friend, Dr. Josef Jelínek, Praha, in fond memories of several joint collecting trips, particularly the one undertaken in 1964 to southern Hungary together with Dr. Ivan Löbl, Genève, Switzerland, a trip that was outstanding and memorable in many aspects. <b>Bionomics.</b> Very little is known about the habitat requirements of this species. Most specimens were taken from pitfall traps, but nothing is known about the habitats the traps were set in, except that most were operating at elevations between 1300–2000 m. A few specimens (from Hubei) bear the habitat note ‘for. park’ (assuming that it means forest park). <b>Geographical distribution.</b> <i>Ocypus jelineki</i> sp. nov. is at present known from Henan, Hubei and Shaanxi. <b>Recognition and comments.</b> <i>Ocypus jelineki</i> sp. nov. may be distinguished from the two remaining species of the <i>lewisius</i> -lineage instantly by the entirely punctate and pubescent abdominal tergite 2, and by the characteristic shape of the aedoeagus. The pubescence of the abdominal tergites shows some variability, the patches of black tomentose pubescence on visible tergites 1 to 3 vary in size and are absent in some specimens and so does also the number of pale brownish hairs surrounding them; the number of intermixed paler hairs in general abdominal pubescence varies to such extent that the paler hairs may be dominant in some specimens that at the same time often lack one or both patches of golden-yellowish tomentose pubescence on visible tergites 4 and 5, and bear pale, yellowish hairs on temporal area of the head (specimens from Shaanxi). Due to the character of the pubescence, the specimens of the Shaanxi population seem to be specifically different. However, both the male and female sexual characters are identical to those of the specimens from Henan and Hubei; the Shaanxi specimens are therefore not considered to represent a different taxon.
