Dysdera aculeata Kroneberg, 1875
Description
Female
D. concinna is significantly larger than D. aculeata (carapace length 5.1-5.4 mm vs. 4.5-5.0 mm). The diameter of the front eyes is larger than their distance in D. concinna but comparable in D. aculeata. Both species also differ in leg spination: D. concinna has no spines on coxae and patellae I-IV; femur I with less antero-apical spines (2.1-2.1.0 vs. 3.2-3.2-3.1) and femur IV with more dorsal spines in basal position (2.2.1.1.1 vs. 2.1.1). Male copulatory organs also differ.
Additional information
This species of Asian origin is not native to Europe (alien species). It had been introduced to Europe at least once and did establish.
