Episcapha (Ephicaspa) yunnanensis sp. n.
( Figs 2–13 View Figs 2–13 )
Description. Body elongate, length: 8.2–9.0 mm; width: 3.5–4.0 mm (bl/bw = 2.35–2.52; average = 2.43); general color black, slightly shining; mouthparts and tarsi dark brown to reddish brown. Each elytron with 2 orange bands; anterior band extending from lateral border to the middle of the second elytral interval, reaching the shoulder at lateral border, with 3 teeth on anterior and posterior borders; posterior band at seventh from base of elytron, almost quadrate, extending from the suture to near the lateral border.
Male ( Fig. 2 View Figs 2–13 ). Head ( Fig. 3 View Figs 2–13 ) strongly and sparsely punctured on vertex, with distinct depression at each side along inner border of eye. Clypeus finely and closely punctured, with anterior border nearly straight, with a fovea on each side of the base. Eyes large, prominent laterally; interocular distance 0.74 times as long as width of head. Antennae ( Fig. 8 View Figs 2–13 ) long, extending a little behind posterior border of pronotum; antennomere III about 1.4 times as long as IV; antennomere VIII slightly wider than VII, as long as wide; antennomeres IX and X semicircular; antennomere XI pentagonal, slightly constricted in middle; relative lengths of antennomeres II–XI: 8.5: 12.0: 8.5: 8.0: 9.1: 9.0: 9.0: 8.8: 9.0: 11.5. Mentum ( Fig. 5 View Figs 2–13 ) broadly pentagonal, pointed apically, with fine punctures; submentum sparsely and roundly punctured.
Pronotum ( Fig. 4 View Figs 2–13 ) widest at base (pl/pw = 0.68–0.73; average = 0.70); sides slightly curved, gradually narrowing in basal half, then strongly so in apical half. Pronotum distinctly punctured on median area; strongly and closely punctured on lateral areas; punctures near lateral margins fine and nal sac in anterodorsal view.
close. Anterior angles projected; posterior angles obtuse. Prosternum ( Fig.6 View Figs 2–13 ) strongly and closely punctured on the lateral areas, strongly and sparsely punctured on median area, covered with golden hairs. Prosternal process moderately dilated apically; anterior border almost straight with narrow margin; prosternal lines sinuate.
Scutellum broadly pentagonal, with fine and spare punctures.
Elytra (el/ew = 1.59–1.64; average = 1.61), widest at basal fourth, then gradually narrowing to apex; each elytron with 8 striae; intervals with fine and sparse punctures, which are relatively finer than those in striae.
Mesoventrites ( Fig. 7 View Figs 2–13 ) finely and sparsely punctured, with a median obtrapeziform depression.
Aedeagus ( Fig. 13 View Figs 2–13 ) strongly curved; median lobe narrow, with apex hooked in lateral view; median strut short, as long as median lobe. Anterior end of internal sac as in fig. 13.
Female genitalia ( Figs 11–12 View Figs 2–13 ) with narrow styli at apex of coxite; proctigeral lobes rounded apically; female spermatheca as in fig. 10.
Type material. Holotype male, CHINA: Yunnan Province, Gengma County, N23°34’ E99°25’, 26 August 2004, Jing Li and Cai-Xia Yuan leg. ( MHBU) GoogleMaps Paratypes: 5 males and 2 females, same date as the holotype.
Etymology. The specific name derives from the type locality: Yunnan Province.
Diagnosis. This new species is closely allied to Episcapha (Ephicaspa) lewisi NAKANE , but differs from the latter in the characters listed in Table 1.
Distribution. China: Yunnan Province.
