 legs, anterior: foreleg (A), mid leg (b) 



Right 



Prothorax shorter and narrower than meso- and metathorax 

 (Figure 591, A); pronotum light, without pattern; median suture thin, 

 indistinct; dark brown posterior margin with a groove; anterior angles 



rounded; lateral margin near pleural 

 articulation with a reddish brown spot 

 posterior to spot of posterior-angle 

 process; this spot then surrounds the 

 epimeron, extends ventrally and almost 

 reaches the median line. 



Anterior-angle seta straight, thin 

 and brown; a smaller secondary seta 

 near it. Anterior margin setae forming 



3 groups: a median, an intermediate and 

 a lateral group; first two groups 

 situated at a distance from the anterior 

 margin; each group consists of 2 setae, 

 a long brown posterior seta, and a 

 shorter and thinner seta anterior to it; 

 the lateral group contains a long seta 

 situated near the margin; the thickened 

 margin of the sclerite bears 3 thin, 

 transparent, small setae between this 

 seta and the anterior-angle setae. 

 Surface setae also forming 3 groups; 

 posterior part of the sclerite with 



4 setae: a long brown seta, 2 short thin 

 setae and one small seta near the long seta; the intermediate group contains 

 2 small indistinct setae; the lateral group consists of a long seta near the 

 margin and a short seta at a distance from the margin. 



Mesonotum (Figure 591, B) larger than metanotum; anterior margin of 

 both sclerites broader than posterior margin; median suture absent; meso- 

 notum with 2 long anterior-angle setae; a short, thin, small seta on the angle; 

 anterior-margin setae large, situated at a distance from the margin; medio - 

 anal seta long, lateral and especially intermediate seta short and thin. 

 Setae of metanotum similar. 



Propleuron (Figure 592) wide; trochantin oblong-conical, sclerotized, 

 with soft, sucker-shaped, projecting apex; setules near the apex transparent; 

 one of them thick at the base, second setule straight, thin; seta near base of 

 trochantin small, spoon-shaped; process of epimeron surrounding the coxa, 

 extending to the ventral side, where the sclerites of both sides end, not 

 reaching the median line; seta of epimeron situated near the pleural suture, 

 small, spoon- shaped. 



Episternum of meso- and metathorax well developed, prolonged anteriorly 

 like the trochantin, with 2 minute setules; seta of episternum (trochantin) 

 situated on the thick margin of the sclerite, near the articulation with the 

 coxa; epimeron, especially that of metathorax, little developed; seta of 

 epimeron thin, small and situated on a membrane. 



Legs yellow, without pattern, relatively short and thin (Figure 593); 

 relative length of legs 80:100:104; dorsal groove of coxae absent. 



Fore coxa with a dorsal indentation that reaches to about the middle of 

 the segment. Both anterodorsal setae short and strong, massive, dark
