Qiu, Lu, Che, Yan-Li & Wang, Zong-Qing, 2017, Contribution to the cockroach genus Ctenoneura Hanitsch, 1925 (Blattodea: Corydioidea: Corydiidae) with descriptions of seven new species from China, Zootaxa 4237 (2), pp. 265-299 : 283-285

Ctenoneura qiuae sp. nov.

( Figs. 12 , 13 C, 16 F, 24)

Type material. Holotype: CHINA: Yunnan: male ( SWU), Butterfly Valley / Hudiegu (º&ȁ), Ma’andi Township (ŞṚẨş), Jinpin County, 14.V.2015, Jian-Yue Qiu leg.

Diagnosis. This species is very close to C. misera in the shape of subgenital plate, but differs in the following characters: 1) Body brown in general, head and antenna dark brown ( Figs. 12 A–B ), while body rusty yellow, head chestnut brown, antenna brownish yellow in C. misera ( Bey-Bienko 1969) ; 2) hind margin of pronotum not hyaline, while hind margin of pronotum hyaline in C. misera ( Bey-Bienko 1969) ; and 3) subgenital plate with an extending structure, hind margin with several long setae, right part of subgenital plate not protruded, stylus short, originating from one process on the left side of the subgenital plate ( Figs. 16 F, 24 F–G); while subgenital plate lacks an extending structure (or may be not distinct), right part protruded, stylus long, originating from the left side of an incision on the subgenital plate in C. misera ( Fig. 16 I).

Description. Male. Body length 7.1 mm; overall length including tegmen 10.2 mm; pronotum length×width 2.3×3.0 mm.

Coloration: Body brown. Head dark brown, eyes black, ocelli white, antennal sockets white, antennae dark brown. Pronotal disk dark brown, with broad hyaline lateral areas. Hind margin of pronotum dark brown. Tegmina and wings with dark brown venations. Legs, abdomen brown. Cerci dark brown ( Figs. 12 A–B ).

Head: slightly exposed ( Fig. 24 A), vertex round, eyes wide apart, interocular space greater than the distance between antennal sockets, antennal sockets round and big, ocelli small, face with a Y-shaped convex. Pronotum: subcircular, with hind margin slightly convex ( Fig. 24 A). Tegmina and wings: fully developed extending well beyond the end of abdomen, venations well defined; tegmen with Sc and branches of R oblique, M with 3 branches, intercalary vein interrupted ( Fig. 24 B); wing with intercalary vein present, M with two branches, CuA with 7 branches, CuP slender ( Fig. 24 C). Legs: front femur type C1, covered with several spines, the base of hind margin rough ( Fig. 24 D). Pulvilli absent, arolia small, tarsal claws symmetrical, simple. Abdomen: supra-anal plate in dorsal view transverse, the middle hyaline, each lateral with one small sharped processes; cerci long, covered with long setae ( Fig. 12 C–D , 24 E). Subgenital plate asymmetrical, hind margin with several long pubescence, right with a small eds, left with an incision, the inner space of the incision transparent, one short stylus on the left side of the incision, originated from one small process, stylus with about five long setae ( Figs. 12 E–F , 16 F, 24 F–G); in dorsal view, the eds forming a small groove towards right, sgs present, curved, basal portion expanded, flat and round, near the basal portion bent circularly, the rest slender, slightly heliciform (apical portion missing) and nested in the eds groove ( Figs. 13 C, 24 G–H). Genitalia: left phallomere: anterior apex blunt, right margin straight, lvp with an extending process towards left, apex acute, ldp with a stout cvp. Right phallomere: R1M tortuose; R2 with rop strong, slp with apex not inflated, elp with membrane and setae, apex round; R3 with acute anterior apex. Transverse sclerite (tvs): twisted; right apex sharpened, near the apex bent obtusely, the bent point with one small process; left portion twisted.

Female. Unknown.

Distribution. China: South Yunnan ( Fig. 3 ).

Etymology. This species is named in honor of Ms. Jian-Yue Qiu who not only collected this species, but also helped collect many other cockroaches for us.
