Astegistidae

Furcoribula furcillata, photographed by R. Penttinen.


Belongs within: Circumdehiscentiae.

The Astegistidae are a cosmopolitan family of mites, most diverse in warm temperate regions of the world (Norton & Behan-Pelletier 2009). Astegistes, Furcoppia, Furcoribula and Maorizetes ferox have tridactyle legs; members of the remaining genera are monodactyle. The Chilean genus Lamellozetes has extremely long lamellae that are longer than the underlying prodorsum (Balogh & Balogh 1992).

Characters (from Norton & Behan-Pelletier 2009): Length 350–600 µm. Integument smooth. Subcapitulum diarthritic; chelicerae chelate-dentate. Prodorsum with true lamellae. Scalps absent. Notogaster glabrous or with ten pairs of notogastral setae; lenticulus absent. Genital plates large; distance between genital and anal plates usually less than length of anal plates. Anal plates with two pairs of setae; three pairs of adanal setae, positioned adanally and postanally. Tarsus I with two solenidia.
