Taxonomic Treatment 



Genus Stilobezzia Kieffer 



(See detailed illustrations: figures 45, 47, 71, 80; for synonymy, see citations 

 under subgeneric headings.) 



Generic diagnosis. — Species usually of moderate to large size, 

 slender, with body hairs not numerous. 



Head: Eyes bare, their inner margins nearly contiguous to broadly 

 separated; interorbital bridge gently curved, bearing a seta in front 

 (female) or shaped as inverted V with no seta in front (male) . Female 

 antenna (figs. 1-40) with III-X oval to barely cylindrical with smooth 

 contour, and XI-XV strongly cylindrical with rugose contour. Male 

 antenna with well-developed plumes; XIII-XV long and strongly 

 cylindrical with rugose contour, III-XII oval to a little elongated 

 with vasiform base. Female mandible abruptly tapering on distal 

 third with few strong teeth on inner side; often with fine toothlike 

 serrations on outer margin near apex. Maxillary palpus in both 

 sexes with III and V subequal to slightly unequal, III with short to 

 long sensilla usually borne in a small, round, shallow, subapical 

 sensory pit. 



Thorax: With or without color pattern, anterior margin of scutum 

 evenly rounded or sometimes narrowed and more convex with a 

 distinct median tubercle. Humeral pits present but inconspicuous; 

 transverse suture distinct laterally. 



Legs: Slender, unicolorous, or ornamented with definite color 

 markings usually indicative of group relations. Claws of female 

 usually large, strongly unequal, sometimes appearing as a single 

 claw with a subbasal tooth (which we interpret as a specialized 

 feature produced by reduction of the small claw and its more com- 

 plete fusion with the larger) ; male claws equal (rarely unequal) , 

 nearly always with tips bifid a very short way; no visible empodium. 

 Tarsomere V in female unarmed (as in the male) or armed with 

 strong spines sometimes modified into specialized, long, blunt-tipped 

 batonnets, usually 2 in number, rarely more. Tarsomere IV bilobed 

 or cordate distally, sometimes the lobes armed with spines; I— III 

 variably bearing stout, usually dark, sharp spines ventrally, usually 

 distally but sometimes at base and midportions. Tarsomeres I— II of 

 all legs beset with ventral rows of uniformly smaller thorny setae 

 (bulbous setae of Kieffer, Clastrier, etc.) usually in 1 row per tarsomere 

 on fore and midlegs, in 2% to 3 rows on I, and 2 rows on II on hind legs.
