Charadra Walker

Charadra Walker, 1865: 445 .

Type species: Charadra contigua Walker, 1865, a junior subjective synonym of Charadra deridens (Gueneé) .

The generic placement of Charadra in relation to other pantheine genera, especially Pseudopanthea and Colocasia, is in need of review, and more than one genus for the species currently placed in Charadra may need to be recognized. Th e morphology of the genus is quite heterogeneous, but important shared genital characters include the following: apex of uncus with slight to very pronounced medial notch; clasper parallel to ventral valve margin (perpendicular in Panthea Hübner) but absent in C. nitens; dorsal tegumen lacking process (lobed in Panthea, prong-like or flange-like in Colocasia); basal costal process absent or highly developed; vesica with two strongly sclerotized cornuti (absent in C. nitens); female ductus bursae sclerotized laterally; corpus bursae lacking signa. Some of the character states treated as autapomorphic for Panthea by Fibiger et al. (2009) are also present in Charadra, including a dorsally membranous aedeagus and the presence of cornuti on the vesica.
