Andrena cyrenaica nov.sp. ( Libya): differential diagnosis to A. tiaretta s.str. and A. orientalis nov.sp.

The specimens of Libya are characterised by colour of flagellomeres (light brown; Fig. 20a), of thorax (reddish-brown), of tibia and basitarsus (reddish-brown) and of wings and metasoma (very light toned, pterostigma yellowish and brown marginated, veins yellow- ish or reddish-brown). There is a similarity to A. orientalis nov.sp. in the pubescence of the head (paraocular area whitish and no brown hairs), scapus and antennal socket (long white hairs, no difference between dorsal and ventral), genal area (whitish hairs; Fig. 20a) and vertex (whitish hairs). The metasoma of the studied specimens is scarcely hairy but there is a possibility that the hairs are rubbed. Concerning all these morphological features it can be concluded that the specimens from Libya are more similar to A. orientalis nov.sp. than A. tiaretta s.str. Clearly different to A. orientalis nov.sp. and A. tiaretta s.str. is the structure of the gonocoxit, with a well exposed and dominant dorsal lobus (Fig. 23b).
