Trematurella Trägårdh, 1942: 111 .

Type species Trematurella stylifera Trägårdh, 1942: 111 , by monotypy.

Diagnosis — Medium size mites, highly sclerotized, with characteristic sculpture. The idiosoma is oval and flat at the dorsal part. The unique characteristics of this species: the large dorsal shield is surrounded by a rather narrow marginal shield. The dorsal setae are serrated, very long and massive, of the same width at the whole length. The female genital shield is large, wide at the base and becomes more and more narrow towards the front (the shape resembles the foot of the iron), with a long narrow appendix at the front, intensively sculptured. The male genital shield is oval, smooth and has no paragenital setae. They have five pairs of sternal setae, two pairs of adanal setae Ad (1-Ad2), and single postanal seta Pa (). There are cavities for the leg hiding, the last ones, hiding the fourth pair of legs, are located across and do not overlap with the opisthosoma. At the first pair of tarsus there is a single claw. The first pair of hypostomal setae (h1) is needle-shaped and smooth, the other ones h2-h (4) are feather-like.

Also the setae at the trochanters of palps are feather-like.
