Propleuron (Figure 753) wide; pleural suture forming reddish brown 

 stripe; episternum without setae; setae of epimeron shorter and thicker 

 than in Macronema; they form massive spines and spinules; a short, 

 thin, primary seta, and 2 or 3 small setae near suture. Trochantin conical, 

 shorter than in Macronema, with teat-shaped membranous apex; unlike 

 in Macronema, strong, light setae present along whole dorsal margin; one 

 of these setae thicker than others (primary seta?); ventral side with 

 2 subapical setules. 



Sternite of prothorax forming a short, transverse plate which is yellowish 

 brown posteriorly, whitish yellow anteriorly, and covers posterior half of 

 ventral surface. 



Meso- and metapleuron form a small, compact sclerite articulated with 

 its dark reddish, brown ends to processes of coxa and notum, brownish 

 black in middle; its dark, median spot has a small, pointed anterior process 

 which represents the trochantin; it has 2 light setules at the end and a seta 

 slightly further basally; seta of epimeron small, thin, situated near posterior 

 margin. 



Forelegs slightly shorter and broader than midlegs; hind legs of same 

 form as midlegs but slightly longer. Legs yellow or yellowish brown. 



Fore coxa (Figure 753) slightly concave anteriorly, convex posteriorly; 

 as in Macronema radiatum, it has a basodorsal conical process and 

 a dark spot near its base; distodorsal indentation deep. Anterobasal dorsal 

 seta near the spot moderately long, strong, brownish; 2nd anterodorsal 

 seta situated subapically, short, spinelike and brown; a row of thin, long, 

 secondary setae at margin of indentation; primary posterior seta thicker
