Genital segment of holotype female specimen slightly wider than 

 long, lateral margins broadly rounded, posterior lateral regions 

 forming large lobe. Fifth legs visible as two minute spinules and 

 single plumose setule from ventral posterior lateral surface of genital 

 segment (fig. 15c). 



Width of genital segment of allotype male specimen equal to 

 length, lateral margins broadly rounded, posterior lateral regions 

 forming smaller lobes than in female. Fifth and sixth legs distinct; 

 fifth legs as two finely plumose setae from slight indentation of 

 posterior lateral margin; sixth as two finely plumose setae and third, 

 short, naked setule from distal end of lobate ventral posterior lateral 

 surface (fig. I5d). 



Abdomen of holotype female specimen rudimentary, fused to 

 posterior surface of genital segment; line of division indistinct except 

 in one paratype specimen and discontinuous in this specimen (fig. 15c). 



Abdomen of allotype male specimen distinct, not fused to genital 

 segment, width approximately twice length (fig. 15d). 



Spermatophores visible on paratype female specimens as two large, 

 circular structures attached to genital segment by necklike connection. 

 Egg strings short, thick, approximately three-fourths length of ceph- 

 alothorax, with four to six large eggs in each string. 



Antennule of holotj^pe female specimen two-segmented, excluding 

 frontal plate, attached to cephalothorax at posterior edge of frontal 

 region, appearing not to be attached to frontal region. First segment 

 of general triangular shape, proximal end wider than length of seg- 

 ment, anterior margin curving sharply to narrow distal end, bearing 

 21 plumose setae; distal margin with three plumose setae, anterior 

 dorsal surface with two nailed setae. Second segment slender, club- 

 shaped; length equal to length of first segment, with naked seta from 

 middle of posterior margin and 10 naked setae from distal surface 

 (fig. 15c). 



Antennule of allotype male specimen similar to that of female 

 though second segment much longer, approximately one and a half 

 times that of female (fig. 15/). 



Second antenna of holotype female specimen three-segmented, 

 attached posterior to antennule base. First segment forming artic- 

 ular surface for second. First segment short, well developed, with 

 long, triangular, distally pointed, posteriorly directed process. Second 

 segment short, well developed, width approximately two-thirds 

 length; with depression on distal surface forming articular surface 

 for third segment. Thud segment with recurved, acuminate terminal 

 process; segment and process longer than combined lengths of first 

 two segments, provided with two small, simple, spinelike processes
