Icius congener

Male I. congener can be distinguished by the shape of the bulb's apex and the distinctive tibial apophysis. The tibial apophysis is elongate and triangular, directed outward with a short tip that turns inward, and has a thickening at its base without a process. The embolus is moderately curved and very small, with the distal portion of the bulb much longer than wide. Females have straight, parallel copulatory canals that widen at the opening, where the diameter is greater than that of the canal itself. This distinguishes them from closely related species like Icius hamatus, where the canals have a narrow apical portion that curves outwardly. Both sexes show a dark dorsal pattern on the opisthosoma (abdomen) with a central lighter pattern, which is more pronounced in females. Males typically measure 3.5 mm in length, while females are larger at 5.2–5.3 mm.

I. congener is distributed around the western Mediterranean region. It has been recorded from Portugal, Spain, Andorra, France (Corsica), Italy, Malta, Algeria, and Libya. Simon (1937) also reported its presence in Sicily and Sardinia. The species gravitates around the western Mediterranean Basin.
