Eresidae  C. L. Koch, 1845 / Eresus  Walckenaer, 1805   19 species

Eresus sandaliatus  (Martini & Goeze, 1778)


Conductor distally long and pointed, with deep furrow. Prosoma 4 mm long. Legs III and IV entirely black, without red hairs. Opisthosoma with 3 pairs of black spots that are usually not bordered with white hairs.

Body length male: 6-11 mm

Epigyne almost rectangular, anteriorly not divided. Vulva narrow anteriorly. Entrance ducts hardly lobed. Prosoma black and grey, never with yellow hairs. Prosoma 7.9 mm long.

Body length female: 8-20 mm
Additional information

35-80 eggs in cocoon, biology presumably similar to E. kollari. In dry sandy heathland.

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.
