Mites of medium size, deep brownish in colour, strongly sclerotised. Idiosoma elliptical, with wide vertex. Dorsal shield weakly arched, surrounded by narrow marginal shield. Ventral opisthosoma with distinctive ornamentation and chaetotaxy, with 9–14 pairs of long, wide, flattened setae. Epigynial shield of female large, with straight lateral edges, its posterior margin behind level of coxae IV. Sternal region with four pairs of sternal setae, of which st4 are the longest, 3–4 times as long as st1–st3. Anus surrounded by two pairs of adanal setae (Ad), of which the anterior pair is very short, the posterior pair much longer. The unpaired postanal seta is absent. Peritreme relatively short, hookshaped, reaching the lateral edge of the idiosoma, without a poststigmatal extension. Gnathosoma with short horn­like corniculi. Hypostomal setae simple; h1, h3 very long, h2 and h4 short. Tarsi I have short claws and a very long terminal seta. The tarsi of legs IV are very long. The pedofossae of legs IV are directed transversely, displaced towards the podosoma.
