Description. Colour yellowish to olive-green. Maximal length, including ultimate legs, ca. 60 mm. Head plate with 2 paramedian sutures occupying the posterior half of head plate (Fig. 14). Antennae composed of 17 articles, the basal 6 glabrous. Tooth plate with 3+1 teeth, the lateralmost one well separated from the others. Trochanteroprefemoral process moderately expanded bearing 4 tubercles (Fig. 15). Legs 1-20 with two spurs on tarsus 2. Spiracles small and rounded. Tergites 1-20 with 2 paramedian sulci (those on first tergite not reaching anterior border), tergite 21 with a complete median suture. Sternites 2 to 20 with two complete paramedian sutures which are well separated anteriorly and posteriorly and narrowing in the middle of sternite. Sternite 21 trapeziform, broader anteriorly. Ultimate pair of legs: coxopleuron with one lateral spine and long and slender process bearing 2 terminal spines; pores not reaching posterior border of coxopleura. The length of coxopleural process varies considerably between specimens. Prefemur, femur and tibia strongly swollen with dorsal furrow, tarsus 1 wider than tarsus 2; prefemur with 2 ventrolateral rows of 3-5 spines, and 8-10 ventromedial and medial teeth and 2-6 dorsomedial ones (Figs 16-17). Pretarsus finely serrated ventrally, longer than tarsus 2.

General distribution. Spain, Algeria, Tunisia, Azerbaijan ( Minelli 2006)

Distribution in Tunisia ( Map 3 View Map 3 ). Widespread in North and Central Tunisia. The range covers the Mogods-Kroumirie Mts. in the west (Feidja, Beni Mtir) and spreads to the eastern part of the Tunisian Ridge (Jebel Mansour and Jebel Zaghouan) and the main coastal area of the Gulf of Tunis (Bizerta, Tunis, Ariana) including the Cap Bon Peninsula (Oued el Abid). Further south it has been found also in the Sahel (Bou Ficha in the district of Sousse). In the past recorded from Tunis, Souk el Arba, Babouch and Ain Draham ( Silvestri 1896, Attems 1908). Dobroruka (1968) reported the species from Savoual (Zaghouan Region) but we were unable to find this locality on the map.

Altitudinal range in Tunisia. Known from sea level up to approx. 800 m.

Habitats. Mixed oak formations dominated by either Quercus faginea   or Q. suber   , coniferous forests dominated by P. halepensis   , mixed forests of Q. faginea   and Q. suber   , Q. faginea   and Pinus pinaster   , P. halepensis   and Quercus ilex   , Q. coccifera   and P. halepensis   . It is also found in semidry open areas, garigue with Olea europaea   , suburban habitats and coastal grasslands.

Remarks. The morphological characters of the specimens examined correspond well with the description of this species given by Attems (1930) which was the most recent description. Cormocephalus   , which currently comprises about 70 species, was divided into three supergroups, each composed of several species-groups ( Schileyko and Stagl 2004). In this tentative division, C. gervaisianus   belongs to the gervaisianus   species group of supergroup III, which is characterized by the presence of complete (rarely somewhat shortened) paramedian sulci on tergite 1; paramedian sulci complete from tergite 2; prefemur of ultimate leg-pair usually bearing ventrolateral spines; coxa of terminal legs with well developed coxopleural process; and pretarsus of ultimate legs longer than tarsus 2.
