diversus Fall - SPECIES GROUP
Det. E. G. Riley, 2011

The species most likely to be confused with the present one are diversus, abdominalis [w. N. Amer.] and longus [AZ] but all are quite easily separated by the tabular characters. In addition to the more remote eyes both diversus and abdominalis have the front claws distinctly enlarged in the male and the ocular lines are more conspicuous. (2)
