several short setae, including 2 thicker primary setae; ventral secondary- 

 setae thin, moderately long; posterior distoventral primary seta strong, long. 



Anterior seta of trochanter short, strong: a thin, secondary seta situated 

 slightly more basally: posterior primary seta longer and thinner; primary 

 basoventral seta long, strong; 2 other anterior setae represented by strong 

 spines, one apical and one subapical; both posterior setae long, dark, longer 

 than basal seta: ventral side with a row of thin, secondary setae and sparse, 

 white chaetoids together with primary setae.

 larval case. 



Femur with short and moderately long, thin setae dorsally and subdorsally, 

 basodorsal seta and apical dorsal seta longer than the others; anterior 

 surface with a row of 5 — 6 short setae, subapical primary anterior seta 

 larger and stronger than the others; posterior surface with short to 

 moderately long setae, a long, strong, primary posterior seta subventrally 

 in basal part; ventral side with a row of 11 small spines closer to anterior 

 margin, spines alternating with primary setae, one of them in form of a 

 large spine; thin, white chaetoids in addition to spines. 



Tibia short, distoventral process less developed than inOe. ochracea; 

 small lobe- shaped spinules apically and subapically; setae moderately long 

 and short, dorsally on anterior surface, several thin setae posteriorly;
