Diagnosis. A subgenus of Omphreus characterized as follows: very elongated, falciform mandibles, very small and flat eyes, protarsomeres of the male not dilated; basal pits of the pronotum very elongated, diverging anteriorly and reaching half the length; in the lateral gutter of the pronotum deep and narrow along the entire length, with 2-6 setae, each of which starts from a small pore-puncture located in the gutter, the striae deep and smooth, the elytral surface smooth and shiny, the mandibles very long, the elytra more or less parallel, with well impressed striae and isodiametric microsculpture but sometimes very weak, partly disappearing.

Description. Body narrow and elongate, completely black, smooth on head and pronotum, with very lightly impressed microsculpture on elytra. Head (Figs 4, 5, 6) very long and narrow, with long falciform mandibles: the right one flattened, the left almost conical; antennae with first article as long as the following two and a half; labrum short, with 4 setae near the anterior margin; all palpi very elongate, with the last article securiform.

Pronotum (Figs 4, 5, 6) very elongate, much longer than wide, sometimes wrinkled, but without microsculpture and micropunctuation. Lateral gutter well marked all along, narrow, with 2-6 pore-punctures: the posterior one more or less at one-fifth of the length, the anterior one (or more) in the anterior half. The basal pits impunctate, anteriorly diverging, reaching forward slightly more than the middle of the length. Prosternum smooth and without microsculpture; the epimera visible from above.

Elytra (Figs 8, 9, 10) elongate, rather parallel-sided, with evident humeral tooth. Striae well marked, smooth, intervals flat or weakly convex, microsculpture absent or isodiametric, but always giving the elytra a very shiny appearance. Lateral gutter narrow; umbilicate series continuous all along the 9th interval.

Legs rather long and slender, protarsi simple in both sexes; tarsi dark brown to black, superiorly not furrowed, onychium inferiorly with two rows of short bristles, nails smooth.

Genitalia (Figs 12, 13, 14): median lobe of aedeagus rather small, in lateral view curved at obtuse angle and with short and pointed tip almost rectilinear; in dorsal view with long ostium, very narrow apical lamella and broadly rounded apex. Last segment of gonaphophyses rather short, attenuate at apex, with 3 long nematiform setae internally (Fig. 17), while these in Paromphreus are longer, with apex very broad and internally with two short spines.

Type- species: Omphreus ( Elladomphreus) krueperi Reitter, 1885 .

Affinities: A subgenus of Omphreus similar to Paromphreus Ganglbauer, 1887 in the large size, undilated male protarsi and sickle-shaped mandibles, but pronotum with basal pits arcuate and reaching slightly more than one half of length (instead of prolonged until the anterior margin); lateral gutter deep and well marked for all its length (instead of very superficial and almost vanishing); lateral setae varying in number from 2 to 7 and mainly placed in the anterior half (instead of 6-10 along the whole length of pronotum) and with pore-punctures small and not evident (instead of very large and evident), placed in the gutter itself (instead of internally with respect to the gutter); elytral striae deep and well marked (instead of very superficial, punctate and hardly visible), elytral microsculpture weak, giving the elytra a very shiny appearance (instead of very strong, giving the elytra a very opaque appearance); apex of aedeagus short and rounded (instead of long and pointed).

While the Turkish species are diffused only in the southern Anatolian peninsula, in an area limited to the east of the province of Mugla and the west of the province of Antalya, the Greek species are distributed in the Pindos chain and in the Peloponnese. The minimum distance between the distribution areas of the two groups is about 400 km .

Here we describe a third species from Greece , collected on the Oros Panakhaikon in the northernmost part of the Pelo-

ponnese, recently discovered by Manfred Egger during the repeated research campaigns he has been conducting for several years also by means of baits in the southern Balkans and in Greece , aimed in particular at the trogloxene and troglobitic fauna.
