contiguous, with four long hairs at the posterior border ; a spur at the 

 postero-external angle, increasing in size from I-IV, where it is about 

 thrice as long as broad ; a short flat spur at the postero-internal angle 

 on coxae I— III, decreasing in size backward. Tarsi long, tapering 

 abruptly (step-wise) ; claws long, pad almost as long. 



Female : unknown. 



From description by Neumann, based on 1 / from Sekroe, New 

 Guinea, collected by S. Schadler (Leyden Mus. Nat. Hist.). In general 

 form this species approaches /. holocyclus (which is Australian) rather 

 than /. rasus (which is African).
