On the posterior edge of the prosoma two areas with ca. 10 transversal stridulatory furrows with a deep petiolar groove between them. Sternum and labium light brown, but darker than prosoma. Chelicerae light brown, with five large tooth-like outgrowths. Metatarsi I and II slightly curved, ventral sides bearing a row of low sharp spines. Abdomen grey, with white spots. Lateral and posterior parts of the abdomen with a brown, lobated folium, whose center gradually fading, the outer side has a white margin. Ventral side with a wide dark longitudinal stripe and a dark ring around the spinnerets. Above the petiolus there is a semicircular sclerotised rim with two stridulatory teeth.

Knwon from southern Moravia, thus expected in adjacent Pannonian parts of Austria and perhaps also Slovakia and Hungary.
