Key to the Species of Oronoqua Fennah

1. Fore wings with reticulate cross venation through whole length ( Gnezdilov et al. 2010, fig. 3B); rostrum with 3 rd segment longer than 2 nd one, narrowing apically ( Fig. 20 ). Panama............. O. ibisca Gnezdilov, Bonfils, Aberlenc and Basset, 2010

– Fore wings with cross venation developed only in its apical half ( Figs. 3 , 6 ); rostrum with 3 rd and 2 nd segments equal in length, not narrowing apically ( Fig. 21 ) ............. 2

2. Ventral aedeagal hooks slightly S-curved in its basal half, without lateral processes and teeth, tapered to apex ( Gnezdilov et al. 2010, fig. 5A). Guyana, French Guiana ................ ................................ O. deina Fennah, 1947

– Ventral aedeagal hooks not sinuate, each hook either with short lateral process near its middle, serrated distally on outside margin beyond lateral process ( Figs. 26, 27 ), or expanded into apical asymmetrically bifid cup-like structure ( Figs. 33–35 ), Ecuador................. 3

3. Generally face and fore wings with dark brown to black stripes and spots ( Figs. 6 , 10 ). Ventro-lateral margins of male anal tube (in lateral view) with two subequal concavities ( Fig. 30 ); apex of ventral aedeagal hook expanded into broad, spoon-like structure bearing an apical and subapical projections ( Fig. 33 ); lateral serrations absent ................. .................................................... O. feria sp. n.

– Generally pale (face and fore wings missing dark stripes and spots) ( Figs. 3 , 7 ). Ventrolateral margins of male anal tube (in lateral view) once concave subapically ( Fig. 24 ). Ventral aedeagal hooks with short lateral process near its middle and with serrated outside margin below lateral process ( Figs. 26, 27 ) .............................. O. orellana sp. n.
