Copidognathus

 Diagnostic figures of generalised Copidognathus, from Bartsch (2006).

Belongs within: Halacaridae.

Copidognathus is a large genus of primarily marine mites (though a few live in fresh water). Species are found living on a wide variety of substrates. They are distinguished by the absence of setae on the penultimate palp segment (Luxton 1990).

Characters (from Luxton 1990): Female with three pairs of perigenital setae and one pair of subgenital setae; palps four-segmented, penultimate segment lacking setae; genu I shorter than either femur I or tibia I; tibia I with three unpaired ventral setae.
