Haplocampa
two-pronged bristletails
Haplocampa is a genus of two-pronged bristletails (Diplura: Campodeidae) established by Silvestri in 1912. The genus contains at least five described species, including four named by Silvestri in 1912 and 1933, and one described in 2019 from Vancouver Island, Canada. Species in this genus exhibit varying degrees of cave adaptation, with some showing only slight morphological modification for subterranean life. The genus demonstrates biogeographic connections across the North Pacific, with close affinities to Pacificampa (Japan/Korea), Metriocampa (Siberia), and Eumesocampa (North America), suggesting historical dispersal via the Bering Land Bridge.
