Genus Longiaedeagus View in CoL gen. nov.
Type species: Longiaedeagus flavofasciatus sp. nov.
Description. Ground coloration brown, forewing with large yellow markings.
Small sized. Head distinctly wider than pronotum, anterior margin of crown in dorsal view round, crown slightly shorter medially than next to eyes ( Fig. 1A View FIGURE 1 ). Ocelli hyaline, around with black markings, situated near ends of lateral frontal sutures ( Fig. 1B View FIGURE 1 ). Face, without median longitudinal ridges, lateral margins broadly convex; anteclypeus flat, short and wide, constricted medially; upper part of face with fine arcuate striations ( Fig. 1B View FIGURE 1 ). Pronotum and scutellum each broader than long. subapical cells; appendix wider than inner apical cell and bordering inner three anteapical cells ( Fig. 1F View FIGURE 1 ). Hind tibia with several stout and long macrosetae, AV with 4 macrosetae in distal half, PV with ~15 macrosetae becoming longer distally, AD with 6–7 macrosetae and PD with 13–14 macrosetae. Hind femur apical macrosetae formula 2 + 0 ( Fig. 1C, D View FIGURE 1 ).
Male genitalia. Pygofer nearly triangular in lateral view, with vertical cleft dorsally near base and membranous area medially; processes absent. Subgenital plates ligulate, approximately as long as pygofer, dorsal margin with dense slender setae. Style moderately long, middle area of apophysis wide, constricted preapically with dense preapical patch of long, fine setae; apex truncate with two acute points. Connective relatively short and narrow with pair of short anterior arms and broad, emarginate stem. Aedeagal shaft slender, slightly asymmetrical, strongly curved dorsad in lateral view, with single (unpaired) long retrorse dorsal process arising preapically and extended based; gonopore large, near midlength of shaft on posterior surface ( Fig. 1H View FIGURE 1 ).
Female genitalia. Female ovipositor strongly projecting beyond pygofer. Sternite VII truncate posteriorly ( Fig. 2A View FIGURE 2 ). First valvulae with striate sculpturing ( Fig. 2B View FIGURE 2 ). Second valvula abruptly beyond midlength in lateral view, dorsal margin of distal part arcuate with numerous irregular teeth ( Fig. 2 View FIGURE 2 C–E).
Distribution. China (Yunnan).
Etymology. The new generic name is derived from the words “ longi ” and “ aedeagus ”, indicating that the aedeagus is slender. The gender is masculine.
Remark. Longiaedeagus gen. nov. is similar to Lambirocerus Xue & Zhang in the long and slender aedeagal shaft and forewing venation, but this new genus can be distinguished from Lambirocerus by the broad style, aedeagus apex not bifurcation, and subapical with long and wide processes in ventral marginal.
