description: Mileewa xiaofeiae Yang, Meng & He, sp. nov.
(Figs 45, 77–91)
Length of males 4.7–5.0 mm, female 4.8 mm.
Coloration. Head, thorax and forewing black in dorsal view. Pronotum and mesonotum markings as a whole Y-shaped: pronotum with median yellowish-brown line, and mesonotum with pair of oblique yellowish-brown line extending to scutellar suture. Scutellum with apex yellowish-white. Forewing with one hyaline marking near apex on costal margin. Face with basal portion black, venter of thorax, and legs white. Abdomen black in ventral view, sternites with posterior margins pale.
External features. Head anterior margin broadly rounded in dorsal view, median length five-sixths interocular width; coronal suture indistinct and only present at basal portion of crown; ocelli located on line between anterior eye angles; frontal suture extending onto crown and attaining ocelli. Face with frontoclypeus convex, muscle impressions distinct, transclypeal suture distinct and complete. Pronotum slightly broader than head, posterior margin approximately transverse.
Male genitalia. Pygofer with posterior margin subangular, ventral margin with small setae; ventral process short, dorsally upturned, with acute apex. Subgenital plate extending posteriorly slightly beyond pygofer apex, surface with uniseriate macrosetae obliquely, near outer lateral margin with long microsetae. Connective Y-shaped. Style slender, with thumb-shaped process and small setae near middle, apex acute. Aedeagus slender and nearly straight, base with short dorsal process and pair of long branched processes, apex with pair of short ventral processes and pair of long laterodorsal processes.
Female genitalia. Sternite VII in ventral view with posterior margin medially conically produced with blunt tip. Valvulae I in lateral view broadly expanded near middle and tapered to attenuate apex; with columns of dorsal sculpture oriented posteroventrad, with dorsal sculpturing imbricate, ventral area with imbricate sculpturing in apex and indistinct strigate sculpturing in distal two thirds. Valvulae II in lateral view broad, strongly broadened near midlength and tapered distally; base of blade with dorsal unpigmented area, distal tapered section finely crenulate, small and closely spaced crenulate and extending to ventral margin near apex.
Etymology. This species is named after the collector of the type series.
Material examined. Holotype, male, China, Guizhou Province, Mt. Fanjing, 25 September 2011, coll. Yu Xiao-fei. Paratypes: 2 males, 1 female, same data as holotype.
Remarks. This new species is similar to M. lackstripa Yang & Li, but differs in the pronotum with a median yellowish-brown line and the mesonotum with a pair of oblique yellowish-brown lines extending to the scutellar suture. Based on male genitalic characteristics, M. xiaofeiae differs from M. lackstripa in having the aedeagus with a basal branched processes, preapical ventral processes and long apical processes, while M. lackstripa has only one pair of apical processes. In addition, the style in M. xiaofeiae has a thumb-shaped process near the median portion, whereas in M. lackstripa the style has no process.
