Propleuron yellowish brown, with broad, black, pleural suture; epimeron 

 oblong, with a small, black spot laterally; seta situated near suture, strong, 

 reddish brown; trochantin mainly blacky seta situated distally, both setules 

 transparent, situated at anterior margin. 



Mesopleuron light, metapleuron lighter, whitish yellow, with dense, dark 

 dots on dark background along pleural suture; episternum with 3 — 4 large 

 dots; setae chestnut brown, with dark dots at base. 



Prosternite yellowish, with indistinct, brown stripe at posterior margin, 

 with small, chestnut brown, sclerotized dots laterally. Horn large, chestnut 

 brown. Mesosternite represented by a number of dark, sclerotized dots, 

 and a small sclerite on each side. Metasternite in form of pale pinkish 

 dots (Figure 482).

Legs (Figure 483) reddish brown. Fore coxae, femora, and tibiae with 

 large distinct dots; mid- and hind legs with indistinct dots; large setae 

 moderately long; a row of small, light spinules at ventral margin of all 

 tibiae and femora, but not on tarsi; fore femur with a tuft of light, hairlike 

 chaetoids similar to those on trochanter ventrally near base; such chaetoids 

 absent near basal margin of mid- and hind femora. Primary ventral setae 

 of fore femur represented by 2 large, light yellow spines of almost the 

 same length situated close together; posterior seta dark, thin, situated 

 slightly distally above spine resembling posterior distal seta of trochanter. 

 Primary ventral setae of mid-femur in form of 2 large, strong, brown 

 spines of equal size, situated in middle of femiur, basal spine slightly thinner 

 than apical; primary ventral setae of hind femur in form of a similar spine 

 in middle of segment, and a dark, strong, moderately long seta situated 

 more distally. 



Dorsal process of abdominal segment 1 small, conical, retracted in fixed 

 specimens, apex represented by a dark brown spot; lateral processes 

 normally developed; 6 — 7 small dark setae on dark, sclerotized dots between 

 dorsal and lateral processes; each half of segment with 2 small, ventral 

 sclerites with several small setae.
