hairs, these evenly distributed on II-IV, the pubescence normal; 

 I with pale mesal area nearly reaching sides. Spermatheca (fig. 88d) 1, 

 ovoid without sclerotized neck, measuring 0.105 mm by 0.067 mm. 

 Genital sclerotization as in figure 886. 



Male. — Length of wing 1.6 mm. Similar to the female with the 

 usual sexual differences; features of abdominal terga as in figure 88h. 

 Genitalia (fig. 88e-g) as in subviridis, but basidorsal process of basistyle 

 strong; dististyle with blunt, bent tip; aedeagal sclerites fairly broad, 

 bases bent, tip with 1 oblique wrinkle; paramere with tip abruptly 

 bent. 



Distribution. — Malaya. 



Types. — Holotype female, Kuala Lumpur, Selangor, Malaya, 

 Sept. 1959, H. E. McClure, light trap (USNM 69481). Allotype 

 male, same data but collected Aug. 1958 by R. Traub. 



Discussion. — This species strongly resembles nudisthmostheca, new 

 species, and differs from subviridis in the distal paleness on the mid 

 tibia and the absence of a sclerotized neck on the spermatheca, but 

 differs from both in the evenly scattered bristles on the second to 

 fourth abdominal terga.
