In Blackburn's table would be associated with niflr/i- 

 collis, from which it differs in being considerably smaller, and 

 by the remarkably wide front tarsi of the male ; from, small 

 specimens of ritfip.es it differs in the very different clothing 

 of upper-surface and different shapes of the inflated front 

 tarsal joints of the male ; in size it is about equal to pitberitfa, 

 but the sculpture and clothing are very different. The tip:- 

 of the clypeus are obscurely diluted with red.

 the claws black, tips of front tibiae reddish. With white, 

 moderately-long setae or elongate scales, fairly dense on head 

 (denser on tips of clypeus than elsewhere), moderately dense 

 on sides, base, and along middle of pronotum (and a few 

 scattered about elsewhere), and forming feeble lines on 

 elytra ; under-surface and legs with moderately-long white

 of tarsi. 



Head shagreened and with crowded, partially concealed 

 punctures; clypeus distinctly and evenly narrowed from base,

 notch almost U-shaped. Prothorax moderatelv transverse, 

 but much longer than the apical width, which is about half 

 that of the base, base bisinuate, but truncate at scutellum,

 median line (except for its clothing) vaguely defined, lateral 

 impressions rather small deep foveae ; finely shagreened'
