Eutegaeidae

Eutegaeus bostocki, photographed by Stephen Thorpe.

The Eutegaeidae are a family of oribatid bites characterised by the presence of long humeral processes on the notogaster, together with a thickened bothridium. In the genera Dudichella, Porrhotegaeus and Pterozetes, these processes are ventrally reflexed, and these genera have also lost the interlamellar setae, leading some authors to separate them as the Pterozetidae. Among other eutegaeids, the New Guinean Birotegaeus biroi is distinguished by the presence of nine pairs of setae on the notogaster (vs eight pairs otherwise) which also possesses a single small knob on the posterior edge (Balogh & Balogh 1992).

Characters (from Balogh & Balogh 1992): Prodorsum with true lamellae. Bothridium long, tubular. Notogaster with long horizontal humeral process, at least as long as half the length of prodorsum. Legs monodactyle.

Belongs within: Circumdehiscentiae.
