Genus Pteronemohius Jacobson and Bianchi, 1904 



The genus Pteronemohius differs from Nemobius Serville in the 

 number of spines of the posterior tibiae, which in Nemobius is always 

 three on each margin in both sexes; the first internal spine is never 

 speciahzed in the male as it is in Pteronemobius. The macropterous 

 condition is not known in the species of Nemobius and no species of 

 the genus has 3^et been found in America.
