Fig. 9 , 17

Diagnosis. Superficially, C. parintina is similar to C. ocelliferana and C. macrospina . The male genitalia are easily distinguished by the conspicuously subtriangular cucullus, the narrower neck of the valva, the absence of spines above the sacculus, and the presence of a small dorsoterminal thorn of the phallus.

Description. Head. Brownish cream; labial palpus reddish brown, dorsum of second segment with bluishblack, narrow, longitudinal stripe; third segment mostly bluish black, slightly metallic. Thorax. Nota brownish cream. Forewing ( Fig. 9 ) length 5.5 mm (n = 1); forewing weakly expanding terminally, termen straight; ground color cream with distinct brownish grey admixture and somewhat darker, dense straitionss and dots; costal strigulae weak, more or less concolorous with ground color, divisions rust in distal 0.33 of costa followed by four short black stripes; a series of minute refractive dots along termen; small spot black at distal end of discal cell with refractive scales in inner dot. Fringe cream brown, rust orange in costal 0.33. Hindwing pale brownish. Fringe cream. Abdomen. Male genitalia ( Fig. 17 ) with uncus stout, rounded-bifurcate apically, with cluster of long setae on each bifurcation; valva somewhat parallel-sided in basal 0.5, with rhomboidal cucullus; sacculus with dense group of setae in posterior half; marginal spines of cucullus rather short; phallus stout, with short flange distally and a single cornutuslike spine (uncertain whether it is attached to the vesica or the outer surface of phallus). Female unknown.
