Corita morai Urra sp. nov.

( Figs. 1, 2 , 19, 20 , 37, 38 ).

Diagnosis. Corita morai is easily recognizable from other species of Corita by having a white FW with abbreviated basal and medial fascia from the anal margin and a grey HW. In C. amphichroma the FW is clay colored, with three black discal spots and two buff spots on the costa; C. nandoi Urra, 2016 and C. guillermoi Urra, 2018 have a brown FW, while in C. attenboroughi Urra, 2017 the FW is white or light grey ( Clarke 1978; Urra 2016b, 2017b, 2018a). The FW of C. morai is comparatively narrower than the other species. Furthermore, the known species of Corita have a narrow uncus and sclerotized anellus, and a sclerotized antrum; C. morai does not share these characteristics. The valva of C. morai is similar to that of C. amphichroma and C. attenboroughi with a subparallel ventral edge and costa, while in C. nandoi and C. guillermoi the valva has a constriction at the end of the sacculus.
