Gymnomerus laevipes (SHUCKARD 1837) ( Fig. 1 )

M a t e r i a l e x a m i n e d: 1 specimen from Greece: Messinia, Artemissia, Nédoussa, 15.VI.1995, P.L. Scaramozzino leg.

D e s c r i p t i o n. Length: 11.5 mm; fore wing length: 9.7 mm. General appearance female-like, metasoma bearing a normally developed sting, without traces of male genital capsule structures, with male traits located exclusively on head (fig. 1). Clypeus moderately asymmetric in shape due to the presence of mixed male and female characters, moderately convex, with medial lobe deeply emarginated, thus resulting in two acute teeth; right half female-like, extensively black with a wide transverse yellow stripe close to fronto-clypeal suture, and tooth weakly shorter than left one; left half male-like, yellow except margins, black. Right antenna female-like, entirely black, quite shorter than left one, stout, moderately clavate, 12-segmented, with scape 3.3 longer than wide, and antennomeres 4-12 transverse (about as long as wide). Left antenna malelike, black with a longitudinal dorso-lateral yellow stripe on scape, 13-segmented; scape 2.7 longer than wide, apex (last three antennomeres) not curved (as normal for male); antennomeres shape intermediate between female and male, less elongate and slender than a normal male antenna; last antennomere incompletely developed and not clearly separated from previous one.
