Pseudomethocadonaeanae(Cockerell&Fox) wasdescribedbasedonfemalesonly,while P. russeola Mickelwas describedbased onmales only. Manley (1999) synonymized P. russeola with P. donaeanaeafterassociatingamalethatsuperficiallyresemblesP. russeola withP. donaeanae. Close examination of male genitalia of specimens currently identified as P. donaeanae, along with additionalmorphological characters, suggests thatthree species are actuallybeing misidentified as asinglespecies. OurcomparisonofthemaleassociatedwithP. donaeanaewiththetypespecimenof P. russeola (male) suggests that these species are not synonymous. The male of P. donaeanae is described for the first time, and P. russeola new comb., is resurrected from synonymy and redescribed. The third species, P. ajattara sp. nov. also superficially resembles P. russeola and P. donaeanae,buthasdefinitivegenitaliawithhookedsetaelocatedventrallyalongtheinternalmargin ofthe parameres. The females ofneither P. russeola or the undescribed species are known.

A study of male genitalia and problems stem from the relative lack of other characters in Pseudomethoca led to the obvious characters useful for diagnosing discovery of three unique species that species based on males. While many currently are identified as P. russeola, with females have unique coloration schemes, all possessing the unique coloration.
