Laelaps hilaris, drawn by Anthonie Cornelius Oudemans.

Belongs within: Laelapidae.

Laelaps is a genus of mites found primarily in the nests of rodents, from which they may feed on lymphatic secretions or blood. They are characterised by the presence of an opisthogenital shield in females and holoventral shield in males (Evans & Till 1979).

Characters (from Evans & Till 1979): Idiosoma with mediodorsal series of setae (jJ) comprising eleven pairs, setae rarely short subspinose, two pairs of Zx setae present; genu III with nine setae; genu IV with ten setae (pl2 present); male with holoventral shield; female with opisthogenital shield present, anal shield free, metasternal setae not situated on sternal shield.
