Map 9: Distribution of Medon nifiventris (Nordmann) in the Eastern Mediterranean and adjacent regions, based on revised re- cords. Comparative notes: For separation from the similar M. pythonissa, quite possibly its sister species, with which M pocofer was frequently confused in the collections examined, see diagnosis above. From M rufiventris, M. pocofer is distinguished especially by larger size, denser puncturation of head and pronotum, a more deeply and broadly excavate posterior margin of the male sternite VII, and by the much larger aedeagus. All other conge- ners occurring in the region have a less shining head, ei- ther because of very dense and coarse puncturation or due to much more pronounced microsculpture. Comments: The types, which according to HORN et al. (1992) are kept either in Beyrouth or in Paris, were not examined; they were not found in the MNHN (N. Berti, Paris, pers. comm. 2002). The species was pre- viously referred to as either Medon pocofera or Medon pocofenis; the correct spelling of the adjectival species name, however, is pocofer (A. Smetana, Ottawa, pers. comm. 2002). Distribution and bionomics: According to Coiffait (1984), M pocofer occurs in Western Europe and the Western Mediterranean, including Northwest Africa. The only record from the Eastern Mediterranean is from Montenegro (Map 8). M. pocofer, a littoral species (Coiffait 1984), is the only Western Palaearctic Medon restricted to coastal Figs. 57 - 60: Medon rufiventris (Nordmann): Aedeagus in lateral and in ventral view (57, 58); posterior margin of male stemite VII (59); outline of posterior margin of male stemite VIII (60).
