Chinecallicerus transversus View in CoL nov.sp. ( Figs 16 View Figs 7-16 , 20-23 View Figs 17-23 , Map 1 View Map 1 )
T y p e m a t e r i a l: Holotype ♀: " CHINA: N-Sichuan, Minshan Mts, Baima pass, 3000 m, 5.-20.VII.2005 [collector not specified] / Holotypus ♀ Chinecallicerus transversus sp. n., det. V. Assing 2018" (cAss). Paratype ♀: same data as holotype (cAss) .
E t y m o l o g y: The specific epithet (Latin, adjective) alludes to the distinctly transverse head and pronotum.
D e s c r i p t i o n: Body length 6.7-7.6 mm; length of forebody 2.9-3.0 mm. Habitus as in Fig. 20 View Figs 17-23 . Coloration: forebody blackish with the postero-sutural portions of the elytra slightly paler, more or less distinctly and more or less extensively pitchy-reddish; abdomen blackish, with the posterior margins of tergites III-VI indistinctly and very narrowly, those of tergites VII-VIII more distinctly and more broadly dark-reddish; legs brown with dark-yellowish tarsi; antennae and maxillary palpi dark-brown to blackishbrown.
Head ( Fig. 21 View Figs 17-23 ) distinctly transverse, approximately 1.2 times as broad as long; punctation dense and fine, but distinct; interstices with distinct microreticulation. Eyes distinctly convex and protruding from lateral contours of head, 0.7-0.8 times as long as postocular region in dorsal view. Antenna ( Fig. 22 View Figs 17-23 ) long and slender, approximately 2.4 mm long; antennomeres IV-X all distinctly oblong.
Pronotum ( Fig. 21 View Figs 17-23 ) distinctly transverse and large in relation to head, approximately 1.15 times as broad as long and nearly 1.3 times as broad as head, broadest slightly anterior to middle; disc very weakly convex in cross-section; punctation dense and rather fine, slightly more distinct than that of head; microsculpture practically obsolete.
Elytra ( Fig. 21 View Figs 17-23 ) large, approximately as long as pronotum; punctation very dense and slightly asperate; interstices with microsculpture. Hind wings fully developed.
Abdomen ( Fig. 23 View Figs 17-23 ) narrower than elytra; tergites III-VI with pronounced anterior impressions; punctation moderately fine and dense, only slightly sparser on tergite VII than on anterior tergites; anterior impressions of tergites III-VI with sparse and very fine punctation; fine transverse microsculpture present in places, but nearly obsolete, visible
only at high magnification (100 x); posterior margin of tergite VII with palisade fringe.
♂: unknown.
♀: posterior margin of tergite VIII distinctly concave in the middle ; posterior margin of sternite VIII broadly and distinctly concave in the middle; spermatheca ( Fig. 16 View Figs 7-16 ) with long and slender distal portion.
C o m p a r a t i v e n o t e s: This species is distinguished from all its congeners by a distinctly transverse head, a large, transverse, and weakly convex (cross-section) pronotum, long and slender antennae, the presence of a pronounced anterior impression on the abdominal tergite VI (unique), the distinct concavity in the middle of the posterior margin of tergite VIII, and by the shape of the spermatheca.
D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The type locality is situated in Min Shan, North Sichuan ( Map 1 View Map 1 ). The type specimens were sifted at an altitude of 3000 m.
