the lower group is approximately the same size, located laterally, and 

 reaches the frontal surface where, however, the ocelli do not adjoin, 

 leaving a free median part. Antennae I have a short, three-segmented 

 peduncle and are slightly bulged in males; the 1st segment is equal in 

 length and width; the 2nd-3rd segments are strongly reduced; the 1st 

 segment of the flagellum broadens proximally, tapers distally, is slightly 

 longer than the peduncle, and densely pubescent ventrally and medially; 

 the distal part of the flagellum consists of small cylindrical segments. 

 Antennae I in females are thin and short and the lone virgate segment of 

 the flagellum has an obtuse tip. Antennae II in males with fused lst-2nd 

 segments; the 5th-6th segments are the longest. Antennae I and II are 

 almost equal in length. 



The pereon is slightly longer than the pleon; the dorsal line is 

 not even; the place of fusion of the coxal plates with the pereon is 

 marked by a shallow groove. The 1st (geminate) somite of the pereon 

 is longer than the mutually equally long somites III-IV and is equal
