description: Genus Eponisiella Emeljanov, 1984
Eponisiella Emeljanov, 1984: 481.
Eponisiella – Tsaur et al. 1986: 98. — Rahman et al. 2014: 326.
Type species Eponisiella guttulinervis (Matsumura, 1914), designated by Tsaur et al. 1986. (= Nisia paludicola Vilbaste, 1968,
original designation, synonymized by Tsaur et al. 1986).
Diagnosis
Body very small. Head concave apically with a stripe medially. Vertex with two posterolateral areolets at base. Lateral carinae of frons ending at frontoclypeal suture strongly convergent apically. Lateral carinae of postclypeus absent. Pronotum without carina, mesonotum with a weak median carina. Tegmina broadened apically with blackish markings, MP 1+2 not branched. Wings with RP not forked. Metatibiotarsal formula: (3+5)-7-5. Male genitalia with pygofer strongly produced in a dorsocaudal angle in lateral view; in caudoventral view, strongly concave medially, each side with a finger-like process with hairs lateroapically.
Distribution
Japan, Russia, Korea, China (Taiwan, Hubei, Jiangsu, Guizhou, Shandong) (Fig. 21).
