Haemogamasus hirsutus, illustrated by Anthonie Cornelius Oudemans.

Belongs within: Laelapidae.

Haemogamasus is a genus of nest-dwelling mites characterised by two or three denticles in each of the anterior rows of hypognathal denticles. Females have small, subovate metapodal shields and the opisthogenital shield is narrow (Evans & Till 1979). Members of the genus vary in habits from free-living scavengers to obligatory haematophages.
