Description
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.
