Libengaia (Nandiana) subgen. nov.

Type species: Litura bharatiensis Malhotra & Sharma , here designated.

Diagnosis. Crown as along medially as next to eyes, subgenital plate without apical membranous appendage, each aedeagal shaft with apical process or processes, a constriction precedes origin of ventral process and ventral process forked close to base.

Description. The new subgenus differs from the nominotypical subgenus by the following characters: a) Crown as long medially as next to eyes (crown longer medially than next to eyes in nominotypical subgenus); b) subgenital plate without distal membranous appendage (present in typical subgenus); c) aedeagal shaft longer than ventral processes rarely shorter, each shaft with apical process or processes (aedeagal shaft short, shorter than ventral process, each shaft without apical processes in nominotypical subgenus); d) preatrial processes are paired and of unequal length (atrial process in the nominotypical subgenus single and distally bifurcate); e) junction between preatrium and ventral process constricted (not constricted in the nominotypical subgenus), and f) ventral process of the aedeagus forked at base so much so they appear pair of processes (in the typical subgenus the ventral process of the aedeagus is single and forked near apex).

Etymology. The name of the subgenus is derived from the Sanskrit word “ nandi ” meaning joy, satisfaction, to which the suffix “iana” is added; gender feminine.
