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.
