21) Sepiana Zeuner, 1941 ( Figs. 21 , 50 , 94 , 118)

Characters. Head just larger than long, ratio maximum width/length of head (from vertex to clipeus): 1.1–1.2. Micropterous, pronotum rounded, laterally triangular, humeral excision absent, keel not evident; Ƥ subgenital plate very short, depressed and provided with a wide emargination; ovipositor regularly recurved; Ƥ VI–VII th modified; hind femora very long, hind femora/pronotum length 3Ƥ: 3.9–4.2; 3 X th tergite with two short processes, cerci broad and flattened. Basal arms of titillators with spines. Colour of lateral lobes of the pronotum is blackish bordered with a white stripe.

Remarks. Zeuner (1941) also included within this taxon species later transferred to the genus Modestana Beier, 1955 ; pronotum shape is the only character similar in the two taxa. It has been treated at genus level by Harz (1969) and Heller et al. (1998), while others have included it within the subgenera of Platycleis . The particular shape of the pronotum, the shortness of the female subgenital plate, the shape of male cerci and processes of the 3 X th tergite are not shared by other taxa.

Distribution. From W Europe to Mediterranean (excluded N Africa) and Turkey.

Number of species known (after Eades et al. 2010): 1) sepium (Yersin, 1854) (type species).
