Drawings of Halolaelaps marinus by Anthonie C. Oudemans.


Belongs within: Gamasina.

The Halolaelapidae are a group of mesostigmatan mites found primarily in damp organic microhabitats, such as compost, manure or intertidal debris (Evans & Till 1979).

Characters (from Evans & Till 1979): Dorsum of idiosoma in deuteronymph and adult with two subequal shields; metasternal setae free on unsclerotised cuticle or on metasternal shields posterior to the sternal shield; leg II of male spurred; tibia and genu of leg I with two anterolateral setae; tibia I of deuteronymph and adult with three ventral setae; genu IV normally with 5 dorsal setae in deuteronymph and adult; palp apotele three-tined.
