REVISION OF SPECIES OF STILOBEZZIA KIEFFER 49 



2RC and vein M 2 and a few anteriorly at tip of cell M 2 ; radius with 

 1 seta at basal arculus; CR 0.82. Abdomen (fig. 546) with numerous 

 strong bristly hairs on terga as figured, I with 14-15 hairs on each 

 side. Genitalia (fig. 54c-e) dark brownish, well sclerotized, short and 

 broad, rounded in profile in dorso ventral aspect; sternum IX narrow, 

 with shallow caudomedian excavation, the ventral spicidation scarcely 

 perceptible; tergum IX short, rounded caudad, with small laterally 

 directed pubescent caudal lobes; basistyle greatly expanded mesad 

 on basal portion, expanded portion provided ventrally with dense, 

 long hairs; distal portion slender; mediangular process short, a small 

 sclerotized bridge present; dististyle stout, moderately curved, apex 

 blunt; aedeagal sclerites bisinuate, a broad expansion on outer mar- 

 gin in midportion, distomedian tip pointed; parameres each with 

 long arcuate lateral arm at base, a small anterior process on this 

 basal sclerite, main portion stout, with a rather pronounced swelling 

 at base, stout and fairly straight on midportion, somewhat abruptly 

 narrowed toward tip, then abruptly bent ventrocephalad in a short 

 ventral point. 



Distribution. — Malaya. 



Types. — Holotype male, King George V. Nat. Park, Pahang, 

 Malaya, 4-6 Nov. 1959, H. E. McClure, light trap (USNM 69455). 

 Paratype, 1 male, same data as type. 



Discussion. — This species is distinguished especially by its fairly 

 large size, robust legs, bristly body and legs, uniformly pale color, 

 the densely hairy mesal expansion at the base of the basistyle, and 

 by the strong, nearly straight paramere with short ventrally directed 

 point.
