Assing 2010 / Panscopaeus andrewesi (Cameron) , det. V. Assing 2010" ( BMNH ) . Comment: The original description is based on an unspecified number of syntypes , among them at least one male , from "Nilgiri Hills (H. L. Andrewes)" CAMERON (1931) . Two syntypes , a somewhat teneral male and a female, were located in the collections of the BMNH. The male is designated as the lectotype . Redescription: Body length 4.1-4.8 mm . Coloration: head blackish-brown; pronotum reddish-brown; elytra yellowish-brown with yellowish anterior, lateral, and posterior margins; abdomen reddish-brown, with segment VII infuscate and the narrow posterior margins of the segments and the apex reddish-yellow; legs dark-yellowish; antennae reddish. Head strongly transverse, 1.18-1.23 times as wide as long ( Fig. 37 ); posterior margin distinctly concave; postocular region weakly convex in dorsal view; posterior angles marked; neck slender, approximately 0.2 times the width of head in dorsal view; punctation of dorsal surface very dense and fine, but distinctly noticeable in the microreticulation; interstices narrower than diameter of punctures ( Fig. 38 ); dorsal surface with subdued shine. Eyes large and bulging, somewhat longer than postocular region in dorsal view. Antenna similar to that of P. yakushimanus . Pronotum ( Fig. 37 ) weakly transverse, approximately 1.05 times as wide as long and approximately 0.9 times as wide as head, widest at anterior angles; punctation and microreticulation similar to those of head ( Fig. 39 ); midline more or less distinct, narrowly less matt than lateral portions. Figs 35-43: Panscopaeus formosanus ( 35-36 ) and P. andrewesi , lectotype ( 37-43 ): median dorsal portion of head ( 35, 38 ); median portion of pronotum ( 36 ); forebody ( 37 ); posterior portion of pronotum ( 39 ); male sternite VIII ( 40 ); aedeagus in lateral view ( 41 ); aedeagus in ventral view ( 42 ); apical portion of aedeagus in dorsal view ( 43 ). Scale bars: 37: 0.5 mm; 40-43: 0.2 mm; 35-36, 38-39: 0.1 mm. Elytra ( Fig. 37 ) 1.0-1.07 times as long and 1.25-1.30 times as wide as pronotum; punctation dense, much less fine than that of head and pronotum; interstices without distinct microsculpture. Hind wings apparently fully developed. Metatarsomere I distinctly longer than II, approximately as long as the combined length of II and III. Abdomen narrower than elytra; punctation very fine and dense; interstices without distinct microsculpture; posterior margin of tergite VII with palisade fringe. ♂ : sternite VII unmodified; posterior margin of sternite VIII strongly concave ( Fig. 40 ); aedeagus ( Figs 41-43 ) approximately 0.63 mm long; ventral process strongly asymmetric, apically not bifid in ventral view. Comparative notes: Panscopaeus andrewesiandrewesi is distinguished from both P. stilicinus and P. breviusculus by the more distinct punctation of the head and pronotum, the more transverse head, the larger eyes (longer than postocular portion), the relatively shorter elytra, the much more strongly concave posterior margin of the male sternite VIII, as well as by the morphology of the aedeagus. Distribution and natural history: The species has become known only from the type locality in southern India . Bionomic data are not available .
