REVISION OF SPECIES OF STILOBEZZIA KIEFFER 101 



lamellae stout. Male genitalia with tergum IX usually rather elongate; 

 basistyle usually elongate with poorly developed basal processes; 

 dististyle long and slender, not strongly curved; aedeagal sclerites 

 varying specifically, aedeagus with well-developed dorsal submedian 

 lobes; parameres with well-developed basal arm; main body columnar 

 with distal tip modified. 



Species included: Stilobezzia inermipes Kieffer, India to Micronesia 

 and Ryukyu Islands; poikiloptera Ingram and Macfie, West Africa; 

 punctivenosa, new species, India to the Philippines; quatei, new species, 

 Viet Nam and Thailand.

dark spots on tips only 2 



Medium-size species; 11 dark spots on wing; veins M b M 2 , and M 3+4 with 

 dark spots on midportions as well as at tips . . punctivenosa, new species 



2. First radial cell with distinct lumen; distal sector of vein R! in a vertical 



line with r-m crossvein; dark spots at tips of veins Mi, M 2 , and M 3+4 

 larger; abdominal tergum I with lateral cluster of 35-40 hairs in female; 

 male genitalia with sternum IX not convex caudad, dististyle gently in- 

 curved, swollen at base; narrow band between mediangular processes of 

 basistyle intensely sclerotized; parameres each with stout, short basal 

 apodeme, main body stouter caudad, caudal tip obliquely truncated and 

 bearing a stout, heavily sclerotized lobe directed ventrad. 



quatei, new species 

 First radial cell nodular; distal sector of vein R^ quite oblique, the r-m cross- 

 vein nearly vertical; dark spots on tips of veins M 1; M 2 , and M 3+4 smaller; 

 abdominal tergum I with lateral cluster of 20-25 hairs in female; male 

 genitalia with sternum IX convex caudad; dististyle strongly incurved 

 from slender base; narrow band between mediangular processes of basi-
