426. Dimerogonus kaorinus, sp. nov. 



Type.— M. C. Z. 4,865. Paratypes.— M. C. Z. 4,866. New 

 Zealand: Kaori Forest, near Swainson (W. M. Wheeler). 



Differs from P. atcr chiefly in the character of the gonopods. The 

 anterior median plate offers an easy means of distinction; this is con- 

 stricted at middle, expanding from here clavately distad with the end 

 bifurcate, the mesal excavation between the arms deep and rounded 

 at bottom. The inner distal process of the coxal or anterior piece of 

 the first gonopods is shorter, and differs in being clavately widened 

 distad and in curving distoectad instead of being essentially straight. 



The lower part of collum narrower, the lateral edge arising from the 

 caudolateral corner more obliquely than in atcr. 



Coloration nearly as in afrr. 



Number of segments, forty-six to fifty-four. 



Diameter of male, 3.1 mm.; of female to 3.9 mm.
