14) Eobiana Bei-Bienko, 1949 (Figs. 26, 55, 91) Characters . Brachypterous, pronotum just excised, flat, median keel present in metazona; Ƥ subgenital plate longer than wide, with a basal keel, side sclerites large, fused with the subgenital plate, apical lobes pointed and deeply incised; ovipositor black, stout, short and regularly curved; hind femora/pronotum length 3: 3.4-3.8, Ƥ: 3.2-3.9; 3 X th tergite incised in the middle, with pointed processes (they may be well separated or semicircularly close); cerci just flattened, rounded and pointed after the inner tooth. Titillators a little divergent, apically hooked. Colour of lateral lobes of the pronotum is blackish; the white stripe is more or less distinct. Remarks . Zeuner (1941) included within Metrioptera all species until then known; Bei-Bienko (1949) described Eobiana as subgenus of Metrioptera , but Storozhenko & Yamasaki (1993) raised it to generic status, including only two species. Ishikawa & Wada (2001) considered it as a valid genus and described other three species. Eobiana may be considered the Japanese and East Asian representative of Metrioptera , from which it differs by the shape of male processes, ovipositor and female subgenital plate. Distribution . E Asia and Japan. Number of species known (after Eades et al. 2010): 5: 1) engelhardti (Uvarov, 1926); 2) gladiella Ishikawa, 2001; 3) japonica (Bolivar, 1890) (type species); 4) nagashimai Wada et Ishikawa, 2001; 5) nippomontana Ishikawa et Wada, 2001. : Published as part of Massa, Bruno & Fontana, Paolo, 2011, Supraspecific taxonomy of Palaearctic Platycleidini with unarmed prosternum: a morphological approach (Orthoptera: Tettigoniidae, Tettigoniinae), pp. 1-47 in Zootaxa 2837 on page 15, DOI: 10.5281/zenodo.296570 : {"references": ["Bei-Bienko, G.
