| Summary: | Subdivision of Apetaenus (Apetaenus) litoralis Eaton into subspecies Eaton’s species is widely distributed in the subantarctic archipelagos, from Macquarie Island, south of New Zealand, to Marion Island, the westernmost island of the Kerguelen Biogeographical Province. After studying this species from various subantarctic sites, I have concluded that this species includes at least three distinct and easily recognizable geographical races, which are herein formally ranked at the subspecific level (see further). Apetaenus litoralis is a flightless, micropterous fly strictly dependant on the nature of the soil microhabitats, like many other terricolous/lapidicolous arthropods, such as spiders and beetles. It is likely that some events of microspeciation can have taken place indeed in those organisms characterized by very scarce vagility, that is with a weak capability of dispersal, rather than in strongly flying insects which are influenced mainly by passive—e.g. storm winds—and active dispersal.
