Yinglun WANG & Rungang TIAN, by light trap; 2♂♂ 18♀♀, Hainan, Bawangling, 25-V-1983, Yalin Zhang; 1♂6♀♀, 17-VI-1983; 1♂2♀♀, 20-VI-1983; 3♀♀, 19-VI-1983; Guangdong, Zhaoqing, Dinghushan Mountain, Yalin ZHANG, by light trap (NWAFU).
Description. Body length: male 2.9–3.3 mm, female 3.0–3.4 mm.
Ground color light yellow. Crown, pronotum anteriorly, mesonotum and frontoclypeal area with irregular milky to creamy yellow patches (Figs 18, 19). Eyes greyish yellow (Figs 18–21). Forewing and hindwing semitransparent (Figs 18, 22, 23). Abdomen yellow. Legs pale yellow.
Basal abdominal apodemes extending to near midlength of sternite IV (Fig. 24). Male pygofer in profile rounded apically, bearing 3–5 rigid setae along posterior margin (Figs 25–29); dorsal bridge in dorsal aspect slightly less than half of total length of pygofer (Figs 25, 29). Pygofer appendage broadened and spatulate, apical margin truncated, ornamented with not numerous microtrichia (Figs 26, 28, 30). Anal tube appendage short, tapered (Fig. 27, 36). Subgenital plate far surpassing end of pygofer side, A group with 3 slender setae, B group setae very short and arranged in irregular row, C-group setae (Figs 27, 34) biseriate subbasally and thence uniseriate toward apex, D-group setae long and gracile, arising subbasally near dorsal margin of plate, scattered in 2–4 irregular rows (Figs 26, 27, 34). Paramere with 6–8 teeth on dentifer, 6–9 setae and sensory pits subapically, apex needle-like, bent dorsad in lateral view (Fig. 35). Connective inverted T shaped, basal margin incurved, caudal margin incised medially (Fig. 33). Aedagal shaft nearly half length of preatrium, curved and narrowed apically, gonopore apical on ventral side (Figs 27, 31, 32).
Etymology. The specific epithet is an adjective derived from the Latin word “ complanus ”, referring to the spatulate ventral pygofer appendage of the new species.
Remarks. This new species is similar to A. apicoserrata but differs from the latter in having ventral pygofer appendage short (not reaching end of pygofer lobe), apical part spatulate and bearing tiny hairs along truncated margin (ventral pygofer appendage surpassing end of pygofer lobe, razor-like and serrated at tip in A. apicoserrata); in having aedeagus constricted and rounded apically in ventral aspect (aedeagus truncated apically and emarginated medially in A. apicoserrata).
Distribution. China (Sichuan, Yunnan, Hainan, Guangdong).
