Ebrechtella tricuspidata is a species of crab spiders belonging to the family Thomisidae. [2]

Subspecies

[edit]

Subspecies include: [3]

  • Ebrechtella tricuspidata tricuspidata (Fabricius, 1775) - Palearctic realm
  • Ebrechtella tricuspidata concolor (Caporiacco, 1935) - Karakorum

Distribution

[edit]

This species is widespread in the Palearctic realm (Europe, Turkey, Caucasus, Russia to Central Asia, China, Korea, and Japan).[4][5] It is not found in Great Britain.[6]

Habitat

[edit]

These medium-sized crab spiders inhabit dry meadows and sunny forest edges, waiting for prey well camouflaged in flower and foliage. [7]

Description

[edit]

Ebrechtella tricuspidata can reach approximately a body length of 5–6 millimetres (0.20–0.24 in) in females, while males are smaller, reaching a body length of 2.5–3.5 millimetres (0.098–0.138 in).[8] The cephalothorax (Prosoma) is light green in females, with sometimes indeterminate reddish markings on the back of the whitish-yellowish abdomen. These reddish markings usually consist of two broad rear-connected bands. Also legs are light green.

Males are clearly different-looking (sexual dimorphism). They have light brown cephalothorax with bright median stripe and the first two pairs of legs, while the bottle-shaped abdomen (Opisthosoma) is usually pale green, laterally with dark brown markings. [7]

Biology

[edit]

Adults from both sexes can be found in May and June.
