Diagnosis
. This species of predominantly ochre with a characteristic white band on the forewing and a small dot in the cell. It belongs to a group of species characterized by a strongly curved sacculus with a horn-shaped protuberance in the dorsal corner, i.e.,
C. terenaula
Meyrick, 1927
,
C. orphnoceros
Meyrick, 1937
,
C. corniapicella
Baldizzone
(in press),
C. sneeubergensis
Baldizzone
(in press), known only from
South Africa
. From these related species,
C. riftella
sp. nov.
it is distinguished by the white band in the middle of the forewing, and in the male genitalia by the shape of the phallotheca, with the longest of the juxta rods ending in a curved and slender point, and by the cornuti, more numerous and larger than the other species.
