Tibia, straight, thin, with a ventral comb of spinules; anterior distal setae 

 (dorsal and subdorsal) smaller than posterior setae, which are very long; 

 anterior ventral seta situated subapically in form of a sharper and longer 

 spine than the smaller posterior seta. 



Tarsus long, almost as long as tibia; all 4 setae situated apically and 

 subapically, both posterior setae longer than anterior setae, which are 

 short and thin. Claw long, with thin, basal spine. 



Abdominal segment 1 with high, conical, pointed dorsal process; blunt, 

 lateral processes wide, apical spinules numerous, thick, dark. Lateral 

 line on segments 3—8 with thin, dark, dense spinules which are longer in 

 the posterior part of the segments. 



Anterior -angle seta of each segment dark in middle; medioanal seta 

 large, dark, longer on posterior segments, on segment 8 long, thicker, 

 resembling this seta on segment 9 but slightly smaller; intermediate 

 and lateral setae small, thin. 



Gills on segments 1—8.

 Medioanal seta long, thick; lateral seta longer; intermediate and anterior- 

 angle setae light, thin, the latter anterior to the former; a yellowish 

 anterior-angle seta on each side. 



Sclerite "b" of anal legs brown or reddish brown, without dots; reddish 

 brown dots near base of thick setae; 2 apical-dorsal setae thin, brown, 

 of the same length; further laterally a dark but shorter seta; a short, 

 thin seta situated closer to the median line and slightly anterior to the thick
