The genus can roughly be broken down into species that are larger than 5.0 mm and those smaller than 5.0 mm. The smaller species are quite uniform in appearance.
(3) This genus is for the most part is extremely difficult to determine to species as available key characters are very subjective, and almost all reliable species ID's require genitalic dissection. Even then there are no available illustrations of genitalic characters for the synonomized genera listed above. G. Hanley (2020) is currently attempting to match all known species with new genitalic imaging.If you have a series of specimens and you can spare a few, Guy can dissect for ID...Pictures of this genus can rarely be taken to species with any confidence.
