along proximal of radius, on Ri bordering IRC, and along R 4+5 

 behind 2RC; alula fringed; macrotrichia sparse along wing margin 

 between 2RC and vein M 2 . Halter with pale stem, knob yellowish 

 brown. 



Abdomen (fig. 57e) : Yellowish brown, terga slightly brownish; I 

 with cluster of 8-9 hairs on each side; II and beyond each with 

 irregular double row of hairs on posterior half and along side margins. 

 Spermathecae (fig. 57/), 2 large functional, highly sclerotized, plus 1 

 small oval rudimentary, the 2 large ones oval without necks, with 

 small hyaline perforations, slightly unequal, measuring 0.116 mm by 

 0.088 mm and 0.109 mm by 0.070 mm. Genital sclerotization as in 

 figure 57o. 



Male. — Length of wing 1.41 mm. As in the female with the usual 

 sexual differences; antennal plumes yellowish brown; claws short, 

 equal, tips blunt, not bifid. Genitalia (fig. 57h-j) short, broad, and 

 well sclerotized brownish; sternum IX broad, ventral membrane with 

 minute spicules; tergum IX narrowed distad with long pubescent 

 caudal lobes, the dorsal surface with 8-10 long bristles on distal 

 portion, bare proximally; basistyle stout, broadest at midportion, the 

 mediangular processes suppressed but their locations connected by a 

 narrow sclerotized band; dististyle short, stout, with blunt tip; 

 aedeagal sclerites bisinuate, narrow basally but unusually stout 

 distally, with the knobbed caudomedian ends meeting on midline; 

 parameres faintly sclerotized, with arcuate lateral arm from bases 

 of each, main body stout, clublike, slightly bent toward the blunt, 

 rounded tip. 



Distribution. — Sarawak; Malaya. 



Types. — Holotype male, allotype female, Limbang, Sarawak, Dec. 

 1951, D. H. Colless, swept from foliage (USNM 69458). Paratypes, 1 

 male, 1 female, same data as types. MALAYA: Selangor, Subang 

 Forest Res., 1959, H. E. McClure, trap. 



Discussion. — This species appears to be related to clavicula Toku- 

 naga and similisegmenta Tokunaga in general features and genitalic 

 structure, especially in the shape of the parameres; however, in both 

 related species the aedeagal sclerites have slender, sharp caudomedian 

 points.

Female. — Length of wing 1.07 mm; breadth 0.040 mm. 



Head: Yellowish brown, antenna and palpus brownish throughout. 

 Eyes nearly contiguous mesad, but separated by a narrow wedge- 

 shaped interocular space (fig. 58a) at upper margin. Antenna (fig. 26)
