Pachylaelapidae

Pachylaelaps sp., copyright Matthew Shepherd.


Belongs within: Eviphidoidea.

The Pachylaelapidae are a group of predatory mites found in soil habitats such as litter or animal nests; dispersal is often by means of phoresy in association with beetles (Lindquist et al. 2009).

Characters (from Lindquist et al. 2009): Tarsus II in female and male usually with one or two of the distal setae enlarged into stout spines (if lacking such spines, female with a genitiventral shield closely bordered by an anal shield or with peritrematic-exopodal shields extending posteriorly beyond coxae IV to fuse with metapodal plates); tibia III and genu and tibia IV each with one anterolateral seta.
