Identification The genus can roughly be broken down into species that are >5.0 mm and smaller ones. The smaller spp. are quite uniform in appearance. (3) Species identification tends to be extremely difficult (key characters being subjective) and usually require dissection. Even then there are no available genitalia illustrations for the synonomized genera. G. Hanley (2020) is 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... Photos can rarely be taken to species with any confidence.
Keys (use with caution):
Range New World: throughout NA and south to Argentina & Chile (8)
