Chicken mite Dermanyssus gallinae, from here.

Belongs within: Gamasina.

The Dermanyssidae are a group of ectoparasitic mites in which females have the second segment of the chelicera much longer than the basal segment. Species of the genus Dermanyssus are found only on birds whereas Liponyssoides may be found on rodents.

Characters (from Evans & Till 1979): Tritosternum present; chelicerae in nymphal stages and female with second article conspicuously elongated, slender, stylet-like with digits minute; tarsi III and IV of male with seta pv2 modified into short tooth-like projection.
