Myrmecophilus baronii Baccetti, 1966: biogeography and genetics (Orthoptera: Myrmecophilidae)

In this article the systematics of the genus Omphreus is revisited, describing a new subgenus for the Greek species previously attributed to Paromphreus. Elladomphreus n. subg. differs from Paromphreus in the lateral gutter of pronotum deep and narrow all along, with 2-6 pore punctures, the striae deep and impunctate, the elytral surface smooth and shiny, the mandibles even longer and thinner. A new species belonging to this group is also described: Omphreus (Elladomphreus) eggeri n. sp. was collected on the Oros Panachaiko near Kalanistra (northern Peloponnese) in an interstitial forest environment. O. eggeri shows an average size smaller than O. krueperi but larger than O. aetolicus, with mandibles very elongated, pronotum smooth, narrower at base than at apex, elytra narrow, subparallel, with clearly marked humeral angles and with several setigerous pore-punctures on stria 6 and interval 7.
