New name. 



Temple weakly to moderately convex, about 0.75 to 0.95 as long 

 as eye; sculpture of pleura and propodeum moderately fine and dense; 

 apex of male clasper with a broad oblique truncation, its lower apical 

 corner distinctly accentuated, somewhat nipplelike; upper edge of 

 male clasper with a polished, submarginal, rounded ridge. 



Male: Black. Facial orbit, often central part of clypeus, man- 

 dible except its base and apex, sometimes base of tegula, stripe on 

 under side of front first trochanter, and often apical spot on front 

 coxa, 3^ellow; maxillary palpus bro^vn, its second segment more or 

 less yellow; legs beyond trochanters fulvous, the hind tibia usually 

 a little darkened and the hind tarsus usually yellow with the basal 

 0.7 ± of the first segment and all or most of the last segment dark

The male clasper of this subspecies (and of perplexus) is usually 

 quite distinct from those of the subspecies laborator and fabricii, 

 but is variable. In some specimens it approaches the shape of the 

 clasper of one or the other subspecies, and occasionally it is not 

 really different.
