Speleognathinae

Dorsal (left) and ventral views of Boydaia sturni, from Skoracki et al. (2012).

Belongs within: Procurvata.

The Speleognathinae are a group of mites endoparasitic in the nasal mucosa of birds and mammals. They have no active instars between larva and adult with all three nymphal instars being calyptostatic within the larval skin (Walter et al. 2009).

Protohydrachnidia

Rhyncholimnochares sp., copyright Ray Fisher.

Belongs within: Hydrachnidia.
Contains: Eylais.

The Protohydrachnidia are a clade of water mites in which the lateral eyes lack muscles, the last pair of idiosomal dorsoventral muscles are arranged in a median position, and the ejaculatory complex has the distal-sclerite arms and apical setae reduced.
