REVISION OF SPECIES OF STILOBEZZIA KIEFFER 71 



spinipes, new species, Philippines, North Borneo; subflava, new 

 species, Malaya; traubi, new species, Malaya. 



Key to the Oriental Species of the Boharti Group ' 



1. Larger species; legs stout with many spinelike bristles; male genitalia gen- 

 erally massive and heavily sclerotized, though ninth sternum oddly narrow ; 

 basistyle stout with a knobbed mediangular process showing no distinct 

 tubercles; dististyle long, stout to tip; aedeagal sclerites slender; parameres 

 quite robust with basal lobe expanded winglike and main body crooked 

 in proximal half with spinulelike process dorsad, distal half strongly ex- 

 panded laterad but gradually tapered caudad to bluntly rounded tip. 



fortipes, new species 



Medium-size species; legs normal in size and vestiture; male genitalia neither 



generally massive nor intensely sclerotized; other characters not as 



above 2 



2. Wing with several macrotrichia along radius; male legs with heavy blackish 



tibial spines; male genitalia with mediangular process of basistyle quite 

 elongate, tip linearly extended and blackish with a group of 3 tubercles 

 basad; dististyle strongly incurved beyond middle, inflated preapically; 

 aedeagal sclerites bisinuate, slender, straight on mesal third, distal tip 

 short and bent; parameres each with main body slender and tapering 



distad to a fine blackish point spinipes, new species 



Wing with 1 or 2 macrotrichia along radius; tibial spines never unusually 

 thick; male genitalia not as above 3 



3. Yellowish brown species; antennomere XV of female with stout apical seta; 



wing with 1 seta at base and another at midlength of radius; vein R4+5 

 meeting costa quite obliquely; halter slightly infuscated; legs moderately 

 spinose; male genitalia with mediangular process of basistyle short, thick, 

 with basal group of 3 tubercles; dististyle short and slightly narrowed 

 in middle; aedeagal sclerites bisinuate, with distinct expansion caudo- 

 medially; parameres each with main body moderately stout, slightly 



outflexed, with stout rounded tip rotunditheca, new species 



Wing with only 1 seta on radius at base; halter pale; otherwise not as above . 4 



4. Greenish yellow to greenish brown species; antennomere XV of female without 



any apical seta; R4+5 meeting costa at right angle; legs sparsely spinose; 

 male genitalia with mediangular process of basistyle short, thick, without 

 basal group of tubercles; dististyle quite long, gently incurved, and tapering 

 to a rounded tip; aedeagal sclerites relatively short with slightly caudo- 

 median expansion; parameres each with main body columnar, tip sharp 

 pointed and abruptly bent ventrad with hyaline swelling at the bend. 



subflava, new species 

 Dark brown species; antennomere XV of female with a stout apical seta; 

 R4+5 meeting costa quite obliquely; legs moderately spinose; male genitalia 

 with mediangular process of basistyle short and thick, obliquely extended 

 mesad with a group of 3 tubercles at base; dististyle rather short, evenly 

 incurved distad with pointed tip; aedeagal sclerites quite elongated and 

 slender, without any caudomedian swelling; parameres each with main 

 body columnar and almost straight, with finely rounded caudal tip bearing 

 a long whiplike appendage traubi, new species 



1 In the absence of specimens, we are unable to place boharti Tokunaga accurately in this key.
