Epicriopsis Berlese

Epicriopsis Berlese, 1916: 34 .

Type species: Gamasus horridus Kramer, 1876 (= Epicrius mollis Berlese, 1887 ), by original designation.

Diagnosis. Fixed cheliceral digit with 3–5 teeth in addition to the apical tooth; movable digit edentate, with one tooth or with fine irregular denticles; membranous lobes attached either to fixed digit or movable digit or both. Dorsal shield heavily sclerotised, ornamented with star-shaped tubercles, minute circular tubercles (in E. walteri ), or without tubercles but with rows of spine-like structures (in the new species here described); with at most 25 pairs of stout and lightly or distinctly serrate setae, of which at least one pair longer than half the length of the dorsal shield. Opisthogaster with 5–6 pairs of opisthogastric setae in addition to circumanal setae, all of which on unsclerotised cuticle (except E. palustris Karg, 1971a , with one pair of opisthogastric setae on ventrianal shield).
