Prosoma black, female: black, head region mostly provided with yellow hairs. Male: black. Legs short and robust. Female: black, provided with bluish light grey hairs. Male: black or reddish, annulated with white, III and IV with red hairs. Opisthosoma female: appears velvety black due to shiny hairs.

Additional information
in colonies in burrows of up to 10 cm depth (1 cm diameter), covered by small shield- or funnel-like web. Female carries lens-shaped cocoon (8-10 mm diameter, approximately 65-100 eggs) to sunny places during the day. Hatching juveniles stay in the female's burrow and feed on her after her death.
This species can bite humans (Nentwig et al., 2013). A bite into a finger caused pain, spreading to the axilla, with fever-like symptoms and an increased heart rate. After one hour the patient had partially recovered and after 2 hours the symptoms had alleviated, but a strong headache lasted for one day and the finger remained sensitive for several days.
