Legs rather long and slender in both sexes, sparsely hirsute ; basal 

 joint longer than broad; joint 2 very short; joints 3, 4, and 7 long, 

 subequal; joint 5 slightly shorter; joint 6 still shorter. Pedigerous 

 laminae minutely reticulated, not striate, 



Gonopods quite similar in appearance to those in Carnbala, indi- 

 cating rather close relationship with that genus. 



Segment 6 of the male with the ventral posterior margin behind 

 each leg expanded backward and inward over the gonopods, form-

 male, posterior view ; d, seventh leg of male, posterior view ; e, seventh leg of female ;

ing two flaplike pieces whose mesial margins lap well beyond each 

 other instead of being in contact along the middle line of the body. 

 In segment 7 the opening through which the gonopods are thrust 

 is broadly rounded behind, the margin raised and thickened, and 

 the median ventral suture is open. 



Males with the first three pair of legs somewhat reduced in size; 

 legs 4 to 7 inclusive with joint 5 expanded on the inner-posterior 

 side into a large truncated lobe projecting obliquely distad to near 

 the middle of the last joint (fig. 10, c, d). Leg 7 of female shown 

 in figure 10, e.
