Fig. 71 : Type locality of Cephennium jordanicum . Ajlun Castle is visible in the background. Etymology : The specific epithet is an adjective derived from the Latin noun unguis (claw) and alludes to the conspicuous pair of claw-shaped structures in the internal sac of the aedeagus. Description : Body length 1.0– 1.1 mm . Habitus as in Fig. 22 . Punctation of pronotum more distinct than that of elytra. Eye rudiments minute, composed of three or four weakly defined ommatidia without pigmentation. Other external and male secondary sexual characters as in C. marasicum and C. corruptum , except as follows: : metaventrite not impressed, only indistinctly depressed in the middle at most; aedeagus ( Fig. 59 ) small, broad, and apically truncate, 0.23-0.25 mm long; internal sac with a pair of large and strongly curved claw-shaped structures; paramere apically extending to apex of median lobe, with short apical seta. Comparative notes : Cephennium unguicum is distinguished from the species of the C. corruptum subgroup by the presence of claw-shaped spines in the internal sac of the aedeagus. For characters separating it from other species of the C. unguicum subgroup see the comparative notes in the following sections. Distribution and natural history : The type locality is situated in Dilek Dağı (in the peninsula close to the Greek island Samos), Aydın province , Southwest Anatolia ( Map 3 ). The specimens were collected at an altitude of 410 m .
