Eylais

Eylais sp., copyright Tom Murray.

Belongs within: Protohydrachnidia.

Eylais is a cosmopolitan genus of mites found in ponds and temporary pools. Larvae are subelytral parasites on various aquatic Coleoptera and Hemiptera. Deutonymphs and adults predate on ostracods and cladocerans. Species that breed in temporary pools spend much of the year in diapause as larvae attached to their hosts while pools are dry (Walter et al. 2009).

Characters (from Walter et al. 2009): Mouth opening surrounded by distinct membranous fringe; prodorsal plate noticeably wider than long, constricted near middle, bearing one pair of setae; genital acetabula conspicuous.
