The genera Homalolinus Sharp, 1885 and Ehomalolinus Bierig, 1934 are revised, and a cladistic analysis, a key to the species, generic redescription, description of new species, and distributional records are included. According to the cladistic analysis, based on 57 characters from the external morphology and male genitalia, Ehomalolinus is paraphyletic in relation to Homalolinus ; the former is thus proposed as a synonym of the latter. The monophyly of Homalolinus is based on 23 synapomorphies. Twenty species are described as new.
