(Fig. 4 a)

Habitat. 20 specimens were collected under stones.

Localities in Tunisia from bibliography. This species was collected previously in Salambo (Zghal & Tekaya 1980) and recently in lagoon of Tunis (Charbagi-Barbirou et al. 2011).

Other localities in the world. Naples (Wilhelmi 1909); Marseille (Chandebois 1954).

Remark. Chandebois (1954) mentioned that Procerodes lobatus and Procerodes dohrni have never been found in association in the Gulf of Marseille. The author revealed the difference allowing distinction between both species:

Shape: body is more elongated and narrower in P. lobatus than in P. dohrni

Auricles: straight and horn-shaped in P. dohrni (Fig. 4 a) and flat, broad, triangular in P. lobatus (Fig. 4 b)

Prepharyngeal area including head is representing third of body in P. dohrni (Fig. 4 a) and half of body in P. lobatus (Fig. 4 b)

Testes are smaller in size in P. lobatus than in P. dohrni
