Diagnosis. Because the lectotype lacks its abdomen, it is impossible to unequivocally associate other specimens with C. ocelliferana   . Under this species name we include a large number of specimens from Brazil, Paraguay, and Venezuela that lack the distinctive white costal strigulae characteristic of C. albistrigulana   and C. osana   , and share similar male and female genitalia. The male genitalia are characterized by a more-or-less rounded outer margin of the valva and a flattened, finlike, hooked flange from the dorso-distal tip of the phallus. The female genitalia are characterized by a distinctly V-shaped posterior margin of sternum 7, similar to that of C. macrospina   and C. tonsana   .

In the lectotype, the bend in the distal 0.4 of the costa of the forewing is at a greater angle than in other specimens associated with the name; however, this feature appears to be somewhat variable among individuals throughout its geographic range. For example, in a pair of specimens from Cacaulandia, Rondônia, Brazil, collected on the same date (Becker no. 80239), one has a distinctly angled costa of the forewing as in the lectotype of C. ocelliferana   ( Fig. 7 View Figures 6–13 ), whereas the other has a more evenly rounded costa. Figure 7 View Figures 6–13 , an image of the lectotype, NHMUK, is considerably darker brown than other images, but this is partially an artifact of lighting.

In the male genitalia of the specimens examined, there is subtle variation in the shape of the valva and in the number of spines along the sacculus, the latter often variable from the left to the right valva of the same specimen. In the female genitalia, the shape of the signum is somewhat variable, as well. Hence, it is likely that the specimens examined represent a species complex rather than a single species, and the trees ( Fig. 1–3 View Figures 1–3 ) also suggests this, although based on short sequences. In specimens from Brazil the signum may have a pair of long slender spines ( Fig. 23 View Figures 22–26 ) or a more typical spindle-shaped signum subtended by a small pair of short slender spines; rarely there is only a spindle-shaped signum (e.g., in specimens from Paraguay).

Redescription. Head. Reddish-brown to brown; labial palpus reddish brown, dorsum of second segment with bluish-black, narrow, longitudinal stripe; third segment mostly bluish black, slightly metallic. Thorax. Nota reddish-brown to brown. Forewing ( Fig. 7 View Figures 6–13 ) length 6.0–7.0 mm (n = 6), pale reddish-brown with faint refractive pale-blue striations and scale patches, a small rounded, upraised patch of silverwhite scales near distal end of discal cell, surrounded by small dark-brown circular patch; costa reflexed downward at approximately 0.6 length from base to apex; distal 0.2 of costa faint orange with few black strigulae; median part of the costa weakly tinged with orange; two pale-cream spots at mid-costa; costa without well-defined areas of dense silver-white striae. Fringe pale-orange tinged with brown, black at apex. Hindwing brown; male with long, well defined anal roll. Fringe brown, paler in the anal area. Abdomen. Male genitalia ( Fig. 15 View Figures 14–21 ) with uncus short, stout, apically bifid, with dense cluster of long spines on each bifurcation; tegumen with rounded dorsal half; socius digitate, slightly broader basally, pendant, finely hairy; valva mostly parallel-sided in basal 0.5, upturned, attenuate, densely spined in distal 0.5; cucullus with a few strong setae along ventral edge in basal half, one basal and one subbasal setae conspicuously larger; patch of long, slender, hairlike setae at venter immediately basad of cucullus; a distinct triangular subbasal process of valva bearing a single spine; juxta shield-shaped; phallus short stout, vesica lacking cornuti. Female genitalia ( Fig. 23 View Figures 22–26 ) with papillae anales unmodified; sterigma mostly membranous with a strongly sclerotized, mesal, suborbicular plate and a pair of narrow lateral flanges postero-laterally; antrum long, spindle-shaped, occupying posterior 0.33 of ductus bursae; ductus bursae relatively narrow, membranous beyond antrum, gradually broadening to corpus bursae without distinct junction; corpus bursae irregularly pear-shaped, weakly and evenly punctuate throughout; signum variable with one or two spindle-shaped blades from an irregularly rounded, sclerotized patch; ventro-posterior margin of segment 7 with deep V-shaped excavation mesally, resulting in a pair of rounded, sublateral lobes.

Types. Lectotype ♂ (abdomen missing), Brazil, Amazonas , Ega ( NHMUK).

Distribution and biology. We record this species throughout much of Brazil, south to Paraguay, and northwest to Venezuela, from approximately 100 to 1000 m elevation. A specimen in the NHMUK from Peru may or may not be conspecific with C. ocelliferana   . Nothing is known of the early stages. Captures throughout the year suggest that the species may have continuous generations.
