REVISION OF SPECIES OF STILOBEZZIA KIEFFER 69 



Key to the Oriental Species Groups of the Subgenus Stilobezzia 



Medium to large-size species; wing brownish, sometimes interrupted by broad 

 pale areas, often with one to several dark spots, alula always bearing 

 fringing hairs; tarsomere V of female of uniform thickness, unarmed or 

 armed ventrally with one or more pairs of stout spines or batonnets on hind 

 legs or on all legs; abdominal terga mostly dark, sometimes with character- 

 istic color pattern on anterior segments; tergal setae often stout and 

 clustered on anterior segments; spermathecae, usually 1 functional or 2 

 functional with a third rudimentary 2 



Small to medium-size species; wing clear gray to brownish without markings, 

 alula lacking fringing hairs; tarsomere V of female strongly swollen at base 

 and bearing a pair of stout spines but no batonnets ventrally; abdominal 

 terga pale basad, distal terga dark; tergal setae sparse; only 2 functional 

 spermathecae, very unequal, the rudimentary third absent (fig. 99). 



Sybleae Group 



Female antennae with III to X quite cylindrical, almost totally pale, with or 

 without apical setae on XV; wing with one to several dark markings; 

 1 RC small to large but 2 RC always well developed, tarsomere V of female 

 with or without batonnets but when present, not more than 1 pair per 

 leg; tarsomeres III and IV very unequal in length; tergal setation though 

 sometimes weak, often including stout setae centrally clustered at least on 

 segments II to IV 4 



Not as above 3 



Female antenna with III-X strongly cylindrical, nearly uniformly dark, with 

 apical seta on XV; vein R^s thickened only near apex; tarsomere V of female 

 on all legs with several sharp-tipped ventral batonnets; tarsomeres III 

 and IV slightly unequal in length; abdomen uniformly brown to brownish 

 with terga lightly setose; male genitalia massive with basistyle showing a 

 distinct ventral lobe; mediangular process short and thick, often obliquely 

 extended at apex and bearing basad a group of 3 setigerous tubercles 

 (fig. 70) Boharti Group 



Female antenna with III-X somewhat vasiform, short, bicolored; XV without 

 any apical seta; vein R4+5 conspicuously thickened in its entire length; 

 tarsomere V of female with a subbasal pair of stout batonnets except on 

 hind leg; tarsomeres III and IV very unequal in length; abdomen pale with 

 showy color pattern on terga, which are moderately setose with conspicuous 

 clumps of long stout setae centrally at least on terga II-IY; male genitalia 

 of moderate bulk, basistyle subrectangular with an additional flange besides 

 the thick, short, basidorsal process (fig. 79) Pictipes Group 



Wing with 2 pale anterior areas and 3 dark spots; tarsomere V in female usually 

 with a pair of ventral batonnets on fore and mid legs; sometimes also on 

 hind leg; abdomen with prominent clusters of strong black setae mesally 

 on terga II-IV in female, to V in male; tergum IV of both sexes dark brown 

 with at least 4 pale spots; female with adjacent terga before and behind 

 IV mostly pale, male with pattern of tergum IV usually repeated to VI, 

 VII, or VIII, though in a weaker form; two functional subequal sperma- 

 thecae with few indistinct hyaline perforations; male genitalia with basi- 

 style short and stout, basidorsal process foot shaped, parameres long and 

 sickle shaped, aedeagal sclerites simple, slender, and straight without any 

 dorsal median lobes (fig. 71) Notata Group
