Fig. 5-6: (5) Cryptophagus bipedes REITTER, 1963, Turkey, habitus; (6) Cryptophagus dilatipennis REITTER, 1888 Georgia.

E t y m o l o g y: Named after the Peloponnese peninsula in Greece.

D e s c r i p t i o n: Male, 2.0 mm, reddish-brown, membranous wings absent, legs and antennae slender. Shiny, surface with puncture strong and moderately dense on pronotum, finer and sparser on elytra (basal third). Covered with uniform pale pubescence, hairs decumbent but coarse, somewhat erected on margin and apex of elytra. Pronotum with a few long hairs projecting the side margin distinctly.

Head without any features and eyes medium-sized with just a few ommatidia. Punctures on head strong and denser as on pronotum.

Pronotum with prominent anterior callosities, moderately short (long as the distance between them and median tooth), surface of callosities poorly visible from above. Median tooth located in the middle of the side margin. Side margin straight behind the tooth, narrowed distally, with a few small teeth. Surface convex, puncture strong, distance between smaller than the diameter. Pronotum moderately transverse (1.4 x broader than long).

Elytra elongated, slightly rounded, side margin partly nearly straight, humeral callus indistinct.

Antennae moderately slender, 11-segmented including a 3-segmented club. Segment 1 nearly round, broader than 2, 2 and 3pear-shaped, 3 somewhat smaller. Segments 4 to 8 more (4, 5, 6, 7) or less (8) longer than broad. Segment 9 and 10 transverse, 11 long as broad and strong asymmetrical. Tarsal formula 5-5-4 (females with 5-5-5). Parameres shown in fig. 2.

C o m m e n t: Similar to Cryptophagus axillaris REITTER, 1875 (fig. 3), C. brisouti REITTER, 1875 (fig. 4), C. bipedes BRUCE, 1963 (fig. 5), C. dilatipennis REITTER, 1888 (fig. 6) and C. reflexicollis REITTER, 1877.

D i s t r i b u t i o n: Currently known only from Greece, Peloponnese peninsula. The specimens were found around Mt. Chelmos, Mt. Erymanthos and Kyllini Oros. The most similar species (see above) were restricted on the Carpathian Mountains (C. axillaris RTT.), Caucasus (C. dilatipennis RTT.), Pyrenean Mountains (C. brisouti RTT.) and Northwest of Turkey (C. bipedes BR.). C. reflexicollis RTT. is distributed in parts of the Carpathian Mountains and Balkans.
