Remarks. This new species is similar to E. ishidai (Matsumura, 1932) (Dworakowska, 1982), but differs as follows: 1) first process of aedeagus curved in caudal view; 2) second process of aedeagus straight in caudal view; 3) second process of aedeagus curved gently in lateral view.

Etymology. The specific name is derived from the Latin adjective “curvus” (curve), which refers to the shape of the 1st process of the aedeagus (Fig 1-D).
