Pronotum (Figure 659) with concave anterior margin, and large, pointed, 

 anterior -angle processes; anterior margin thick, brown, surrounding entire 

 angle process and extending to anterior part of lateral margin as a narrow, 

 dark brown stripe; posterior margin black, brown at triangular, posterior- 

 angle process; base of triangular process with a brown stripe representing 

 beginning of the brown, curved, lateral ridge extending forward on sclerite 

 surface; other surface yellowish. Primary anterior -angle seta situated 

 near end of process; 2 similarly thick dark setae situated medially at 

 small intervals; 4 short brown setae situated between thick setae, and 

 lateral to them; 2 large, dark setae situated close together near distal end 

 of ridge some distance from anterior margin, a short thin seta near process; 

 2 long, dark, and a small, thin seta in middle of pronotum; dark area of 

 lateral margin with 3 short thin setae and several small, light, conical 

 spinules. 



Mesonotum incompletely and irregularly sclerotized; median tergite 

 large, divided by median suture, distinct mainly anteriorly, with a smaller 

 anterior -angle tergite on each side; median tergite with a thicker, wide, 

 brown oblique area in each half, with a large dark chestnut brown spot 

 posteriorly, other surface yellow, thin, with pale, tapering processes 

 posteriorly; anterior -angle tergites small, narrow, with a group of 6 dark 

 setae at anterior margin, including 3 large setae (one of them primary), 2 

 shorter and one small, thin seta; anterior -margin setae short, situated near 

 margin in light median part; medioanal seta long, similar to anterior -angle 

 seta, dark; intermediate and lateral seta small, thin. 



Metanotum membranous, with small, oblong, anterior -angle sclerites; 6 

 setae situated at anterior margin, primary and secondary setae longer than 

 on mesonotum; anterior -angle setae situated on sclerotized dots; surface 

 setae situated close together on a small oblique sclerite; medioanal seta 

 moderately long, other 2 setae short, intermediate seta much smaller than 

 lateral. 



Propleuron with oblong, brown plate; pleural suture dark, oblique; 

 epimeron smaller than episternum; seta of epimeron dark brown, short, 

 situated near suture; trochantin large, sickle-shaped, covered with 

 numerous, rough, spine -shaped processes, and small light setae, among them 

 the short, dark, primary seta of trochantin at base of segment; small 

 setules among small setae. 



Pleurites of meso- and metathorax in form of brown triangular plates 

 with dark pleural suture from apex to base; distal margin with dark and 

 light areas; both setae moderately long, dark, seta of epimeron slightly 

 shorter. 



Ventral side of prothorax with a small, thin, yellowish, median sclerite 

 with 2 small dark processes at anterior margin. Mesosternites paired, 

 brown, transverse, small, with a narrow dark stripe. Metasternites 

 similar but much smaller, almost intersegmental at posterior margin. 



Forelegs shorter and more massive than other legs; hind legs much 

 longer and thinner; ratio of length of legs 55:100:152. 



Fore coxa (Figure 660, A, D) short, massive, wider basally with shallow 

 distodorsal indentation; basal margin narrowly dark reddish brown. Setae 

 dark, strong, reddish brown; both anterior dorsal setae situated close 

 together, apical seta situated at margin of indentation, basal seta some 

 distance further, much longer; posterior distodorsal seta similarly long;
