 The species is very close to divisus and sicamus* but is distinct from 

 these two species in the structure of the genitalia. The species also 

 may be. according to Wagner's statement, based only on the male of 

 Megarthroglossus bisetis Jordan and Rothschild, which was taken 

 from a Neotoma,
