 acetabular pit; outer tubercle with a straight or slightly curved, relatively 

 short brown basoventral seta near the base on the distal side; distodorsal 

 seta situated nearby, in a saddle-shaped notch anterior to the tubercle; 

 it is curved and light. Apex of right mandible with two teeth separated by a 

 notch, one on the little marked upper blade and one on the lower blade; the 

 latter has a serrated part; basal margin of this part with a large conical 

 process; the tubercles at the base resemble those on the left mandible; 



279 median tubercle slightly smaller than that on the left mandible; outer 

 tubercle is larger; setae similar.

 seta short and yellowish; stipes with a sharp, dark, longitudinal rib; both 

 setae situated on a membrane; basal seta strong and dark. Palpiger 



280 shorter than the 1st palp segment; distal seta on the membrane large and

 dark brown; the 1st segment (not the 2nd) is the longest; the 3rd 

 segment is the shortest; galea short with numerous long, light hairs.
