Glomeremus pileatus (Krauss, 1902)
Material examined. Socotra, Di Lisha 4.IV.2008, B.Massa on Croton sp. (13); Ra’s Shoab 6.IV.2008, B.Massa (1Ƥ); Wadi Zerig 8.IV.2008, B.Massa (13); Wadi Ayev 20.II.2009, P.Lo Cascio & F.Griti (1Ƥ).
Remarks. The typical pattern of the pronotum with two dark bands in the middle of the pronotum (Figs. 1, 2) and microscopic stridulatory ridges, covered by setae, along the sides of the 2nd and 3rd terga consent to ascribe them to G. pileatus . Types (1 male and 2 females) came from Ra’s Shoab (Krauss 1907), and according to Uvarov and Popov (1957) and Wranik (2003) it appears a rare species, known on the area of airport and Hadibou plain. The ovipositor is very thick, with an evident central furrow along its upper side (Figs. 3, 5); the subgenital plate is provided with an arc-like swelling (Figs. 4, 6). This species, lacking of scale-like tegmina, is possibly more related to G. capitatus Uvarov, 1957 than to G. mediopictus Uvarov, 1957 . It shares with the latter the presence of stridulatory ridges, lacking in the former; conversely, the ovipositor of G. mediopictus (Fig. 7) and the general structure of the body are weaker than those of G. pileatus .
