Microptila hamatilis n. sp.
( Fig. 3 View FIGURE 3 )
Diagnosis. The new species is somewhat similar to Microptila hintama OLÁH 1989 from Vietnam in having a broad subgenital plate with lateral margins curling up in dorsal view. However, M. hamatilis n. sp. differs from it by having 1) the posterior margin of the dorsum of segment IX has a median U-shaped concavity in dorsal view (with a mesodorsal triangular projection in M. hintama ); 2) the distal half of the aedeagus is not protruding basally but its apex forms a slender hook (with a triangular protrusion at the base of distal half and its apex is not hooked in M. hintama ); and 3) the inferior appendages are fused for their basal 1/5, with the distal portions gradually diverging in ventral view (the inferior appendages are not fused at base, with their inner margins very close, almost parallel to each other in M. hintama ).
Male. Length of each forewing 2.7–2.8 mm (n=2). Antennae each 20–22-segmented (n=2). Ventral process on sternum VII absent.
Male genitalia. Abdominal segment IX short dorsally, with lower half of anterior margin on each side strongly produced forward and with posterior margin roundly convex in lateral view ( Fig. 3 View FIGURE 3 A); anterior margin of dorsum IX with deep semicircular excision, concavity on posterior margin U-shaped in dorsal view ( Fig. 3 View FIGURE 3 B); in ventral view, anterior margin with deep triangular excision. Segment X membranous, only about 2/3 times as long as wide with posterior margin roundly convex in dorsal view, with its tip tilted slightly upward in lateral view ( Fig. 3 View FIGURE 3 A, 3B). Inferior appendages stout, each about 2.5 times as long as wide and with blunt tip almost 2/3 times as tall as its midheight in lateral view; in ventral view, inner margins of inferior appendages fused at their basal 1/5, then widely divergent, lateral margins roundly convex; in dorsal view, inner surface of each appendage concave such that its dorsomesal margin looks ridge-like ( Fig. 3 View FIGURE 3 B). Subgenital plate forming broad hood with rounded apex and with two lateral margins curling up in dorsal view ( Fig. 3 View FIGURE 3 B), its tip extending to 2/3 distance of inferior appendage from base in lateral and ventral views ( Figs. 3 View FIGURE 3 A, 3C); Aedeagus long, with proximal half 1.3 times as long as distal half, spiral titillator circling aedeagus 1.3 times and apex of aedeagus reduced to slender hook ( Fig. 3 View FIGURE 3 D).
Holotype. Male, CHINA: Yun-nan Province, Da-li City, Zhong-he Village, N25.35°, E100.13°, alt. 2200 m, 22 May 1996, Coll. WANG B-x. and GUI F-r. Paratype. Si-chuan Province, Lu-ding County, 5 km south of Muo-zigou, N29.55°, E102.14°, alt. 1350 m, 7 June 1996, Coll. YANG L-f. and WANG X-h. 1 male and 1 female.
Etymology. Latin, hamatilis = with hooks, or hooked, referring to the hooked apex of the aedeagus.
