 front and on extreme lateral margins; with 4 large bristles, usually 

 also with 2-3 smaller hairs. 



Legs (fig. 81c): Yellowish; coxae, trochanters, extreme apices of 

 tibiae, and tarsomere V brownish; fore femur with faint posterodorsal 

 infuscation broadly on midportion; claws (fig. 81i) long and slender, 

 as long as V, basal tooth half as long as claw; I— III with strong ventral 

 spines as: fore leg 1-2-1, 0-0-1, 0-0-2; mid leg l-(2-4)-2, 0-0-2, 

 0-0-2; hind leg 1-0-1, 0-0-1, 0-0-1. Hind leg with femur to V lengths 

 as 88-98-56-28-11-9-17; TR 2.0; hind tibial comb with 6-8 spines. 



Wing (fig. 81e): Faintly brownish, with 11 small dark brown spots 

 as figured; 1 over IRC, r-m and stem M; 1 on and just behind the 

 beadlike swelling near tip of R4+5; a fainter hourglass-shaped spot 

 subapically at anterior margin of cell R 5 ; 4 linear spots just before 

 apices of veins M 1} M 2 , M 3+4 , and Cu x ; 2 linear spots just beyond 

 midlengths of veins M x and M 2 ; 1 at midlength of M 3+4 ; and 1 at the 

 juncture of the mediocubital fork. CR 0.74; IRC extremely small, 

 cell space sometimes indistinguishable; vein Ri oblique, arising slightly 

 proximad of the vertical r-m; r-m to stem M lengths as 5:4; macro- 

 trichia absent; 4-5 setae along proximal half of radius. Halter with 

 stem pale, knob dark brown with a pale subapical ring. 



Abdomen: Terga brownish without color pattern; setae (fig. 81/) 

 sparse, mainly toward the sides; I with cluster of 15-20 setae on each 

 side. Spermathecae (fig. 81g) ovoid with short sclerotized necks, 

 slightly unequal, measuring 0.056 mm by 0.042 mm and 0.053 mm by 

 0.036 mm. Genital sclerotization (fig. 81 h) with lobes of sternum IX 

 elongate, triangular; internal lamellae also expanded triangularly 

 caudad. 



Male.— Length of wing 1.30 (1.13-1.36, n=20) mm. 



Similar to the female with the usual sexual differences; antennal 

 plume dark brown throughout. Genitalia (fig. 81;'-/) with sternum IX 

 moderately broad, with shallow caudomedian excavation, the ventral 

 membrane spiculose a short distance; tergum IX elongate and tapering 

 on distal portion; basistyle elongate, slightly broadened mesally at the 

 short, anteriorly pointed, mediangular process; dististyle slender, 

 nearly straight distad; aedeagal sclerites distinctively bent bisinuously, 

 each with lateral end slender, broadly rounded outer expansion to- 

 ward midportion, distomesal end slender, with a long curving neck 

 ending in pointed tip, dorsal submedian lobes moderately sclerotized; 

 parameres each with detached basal apodeme broadened at mesal end 

 and narrowed laterally, main body in form of moderately stout straight 

 column slender at base, slightly narrowed subapically, with distal tip 

 slightly broadened, obliquely truncated with fine irregular serrations. 



Distribution. — Thailand; Ceylon, India, Malaya, Philippines.
