This species, the smallest of the North American members of the 

 genus, may be separated from the other North American species of 

 Nemobius belonging to the subgenus Neonemobius by its very small 

 size, slender build, and very dark solid coloration. 



The species resembles N. confusus closely in general appearance, 

 but examination quickly shows that species to belong to the subgenus 

 Eunemobius. 



The closest affinity is found in N. cubensis, from which species it 

 differs in being smaller in the great majority of cases, of darker and 

 more solid coloration, without tegminal markings of any kind. 

 In the male the tegmina are almost always less broad, and in the 

 female are usually more abbreviate.
