Meso- and metanotum (Figure 669) larger than pronotum; color of 

 background and covering setae similar, thinner and sparser on metanotum; 

 light median stripe is broad. Numerous small dots and a dark stripe 

 extending obliquely from the anterior angle to the curvature of the trans- 

 verse suture anteriorly; larger and sparser dots posterior to the suture. 

 Minute setae at anterior margin shorter, thinner and slightly lighter than 

 on pronotum, but more numerous, 70—80 on mesonotum and 50—55 on 

 metanotum; surface setae concentrated in anterior third and posterior to the 

 transverse suture; a relatively large, light brown seta and 2 smaller light 

 setae medial to it in the anterior third, at a distance from the light stripe; 

 one seta laterally, anterior to the median group of dots, closer to the 

 anterior margin; a long light brown seta (medioanal seta?) posterior to the 

 suture near the median stripe, 2 small, light setae situated lateral to the 

 curvature of the suture. 



Pleural sclerite of prothorax yellowish brown, slightly oblong, irregularly 

 quadrangular, with dark pleural suture from the posterodorsal angle to the 

 anteroventral angle; a large black spot near the end of the suture in anterior 

 4 69 part of episternum and in posterior part of epimeron; episternum convex, 

 with indistinct large grayish spots; epimeron with a thin brownish primary 

 seta near the rounded posterior angle and several secondary setae, which 

 form reddish brown, short spinules or smaller hairlike spinules. Trochantin 

 free, conical; primary seta straight, thin, relatively long in middle of the 

 ventral margin; both setules light, whitish, situated on a membrane near 

 the distal end; dorsal side with 2 thick and several thin spinules. 



Pleural sclerites of meso- and metathorax of irregular form, with pointed 

 dorsal angles; posterior margin of epimeron rounded; anterior margin 

 of episternum concave; pleural suture brown basally, light in the middle, 

 broadly blackish brown apically, continuing in the broad apical margin of 

 the episternum; epimeron with indistinct, grayish coarse dots; epimeral 

 seta near margin short, straight, light; sclerite also with 8 thin and thick 

 spinelike setae. Trochantin tongue -shaped, not fused with episternum; its 

 basal margin brown; seta at its base straight, dark brown, longer than 

 epimeral seta; 3 spinelike setules, 2 primary and 1 secondary seta slightly 

 further distally. 



Anterior margin of large sternite of prothorax narrowly blackish brown, 

 with a blunt median process; a transverse curved groove at which the 

 sclerite is inclined at an obtuse angle in the middle; posterior part of 

 sclerite with a quadrangular reddish brown spot in the middle. 



Mesothorax with one tufted gill near the base of the legs; such a gill 

 also on the metathorax near the base of the legs and ventrally near the 

 midline. 



Covering setae of membranous areas of thoracic segments as dense and 

 small as on the sclerites but lighter and softer; a similar covering present 

 on the membranous surface of the abdominal segments. 



Forelegs (Figure 670) prehensile, short, directed anteriorly; midlegs and 

 especially hind legs much longer; ratio of length of legs: 70:100:110. Legs 

 brown, without dots or with small indistinct dots; sclerites with brown, 

 curved, covering setae, which are either very small or slightly longer; they 

 are uniformly interspersed with thin light hairlike setae adpressed to the 

 sclerite. Primary and secondary setae dark, blackish brown, brown or 

 yellowish. Chaetotaxy of legs rather variable.
