Celaenopsoidea

Dorsum (left) and venter of Celaenopsis austriaca, from Evans & Till (1979).


Belongs within: Trigynaspida.

The Celaenopsoidea are a diverse group of mites associated with various arthropods and reptiles (Lindquist et al. 2009b).

Characters (from Lindquist et al. 2009b): Deutonymph with separate podonotal, mesonotal, and pygidial shields; adults usually with holodorsal shield bearing an unpaired median seta at its anterior margin (adults of Neotenogynium retain free shields as in deutonymph). Mesogynal shield small, triangular, and free or amalgamated with latiglynal and/or ventral elements; latigynal shields free or fused to ventral plate; vaginal sclerites well developed. Sternal shield bearing 3-4 setae; free metasternal shield bearing st4 and stp3 often present. Venter covered by single extensive plate, or plate flanked by free lateral and/or anal shields. Palptibia and tarsus distinct, unfused; palpgenu with 5-7 setae; chelicerae with robust, dentate digits, movable digit with large proximal tooth and dendritic or brushlike excrescences. Male genital opening on anterior margin of sternal shield.
