( Figs. 7, 8 , 25, 26 , 43 ).

Diagnosis. Gildita versicolora sp. nov. is easily recognizable by its color pattern that includes the FW with basal three fifths brown and the distal two fifths white. In the male genitalia, the posterior end of the ganthos has a membranous lobe, the sacculus of the valva has a sclerotized process and the cucullus is membranous. G. luteonigra is yellow in color with dark brown or black fascia on the FWs, the gnathos is subtriangular and the valva has sacculus and costa sclerotized, without process ( Beéche 2014).
