TYPE MATERIAL. Holotype. “ PERU: Dpto. Amazonas / Cordillera Colán , E La / Peca, el. 10,000 ft. 13– / 15- IX- / 1978 L.J. Barkley // collected / in pajanal (sic) // LSAM / 0300513 ” one male ( LSAM).

REMARKS. This new species is one of a few species of Carineta to have large opercula including C. basalis , C. bitorquata n. sp., C. carayoni and C. crumena . The distinctive bronzing and maculation of the fore wing and the spot of infuscation and bronzing of the hind wing quickly distinguish this new species from the others with large opercula.

ETYMOLOGY. The name is a combination of castane - (L., castanea, of the color of chestnuts) and - opercula (L., operculum, cover, lid) in reference to the large castaneous male opercula found in this new species.

Hind wing venation ground color except castaneous anal vein 3, spot of infuscation on proximal apical cell 4 extending into distal medial cell and proximal apical cells 3 and 5, double lines of infuscation in distal apical cells and on marginal area of hind wings, infuscation on ambient vein and surrounding margins of anal cell 2.

Legs. Legs greenish testaceous, castaneous mark on distal hind coxae, femora striped with castaneous, distal tibiae castaneous, metatarsus marked with piceous, pretarsal claws ground color at base with piceous tips. Fore femora proximal spine largest, adpressed to femur, elongated reaching to base of secondary spine, small secondary spine almost upright, very small angled tertiary spine and angled apical spine slightly longer than tertiary spine, all spines castaneous with piceous tips. Tibial spurs and combs castaneous with darker tips. Legs with long piceous pile on coxae, trochanters, femora and proximal tibiae, tibiae radiating long golden pile. Meracanthus short, broadly triangular, ochraceous, reaching over anterior opercular margin.

Opercula. Male operculum large, inflated, roughly forming an equilateral triangle, castaneous with piceous mark on base extending to anterolateral margin covered, with silvery pile on base, radiating long golden pile, rounded posterolateral and medial margins, not meeting medially extending only to medial meracanthus, reaching to posterior of sternite V.

Abdomen. Abdominal tergites castaneous with piceous anterior margin, piceous expanding on lateral tergites 4–8, tergites 2 and 3 with central dorsal regions dark testaceous, tergites covered with long piceous pile, long silvery pile posterior of dorsolateral tergite 3–6, extending further laterally in tergites 4–6 reaching maximum length in tergite 5, long piceous pile radiating from piceous auditory capsule. Timbal exposed, white with nine castaneous ribs.

Epipleurites dark testaceous medially, dark castaneous laterally with silvery pile on posteromedial corner and radiating long piceous pile.

Genitalia. Male pygofer testaceous with castaneous margin, piceous spot on ventral margin between basal and upper pygofer lobes, radiating long piceous pile.

Female is unknown.

MEASUREMENTS (MM). N = one male. Length of body: 25.40; length of fore wing: 37.25; width of fore wing: 13.15; length of head: 3.85; width of head including eyes: 7.20; width of pronotum including suprahumeral plates: 11.95; width of mesonotum: 10.25.

DIAGNOSIS. Similar large male opercula are found within the genus only in C. basalis , C. bitorquata n. sp., C. carayoni and C. crumena . This new species can be distinguished from other large opercular species by the distinctive bronzing and maculation of the fore wing and the spot of infuscation and bronzing of the hind wing. In addition, the new species can be distinguished from C. basalis by the piceous fascia on the dorsal pronotal midline, the hyaline fore wings in C. basalis . The new species has significantly more dorsal marking and the very large castaneous opercula not found in C. bitorquata n. sp. and lacks the double banding pattern on the pronotal collar of that species. It can be distinguished from C. carayoni by the lack of bronzing in the wings, the lack of wing maculation, the highly contrasting pronotal collar, the basal lobe appendage with expanding to terminate with four points and not crossing the midline, and the smaller opercula that have a semicircular posterior margin of that species. Carineta crumena can be distinguished by the lack of bronzing in the wings, the lack of wing maculation, the smaller body length (20 vs. 25 mm), the piceous fascia on the dorsal pronotal midline, the basal lobe appendage which is a short, spine-like appendage reaching only the length of the basal pygofer lobe, and the smaller opercula that reach only to the middle of sternite IV. The new species can be quickly distinguished from the other species with a spot of infuscation in the hind wing by a combination of the bronzed fore wings, the infuscation on the fore wings radial and radiomedial crossveins and the large opercula.

DISTRIBUTION. The species is known only from the holotype collected in Cordillera Colán , Dept. Amazonas, Peru. The locality (Pajonal) is a high steppe dominated by dwarf shrubs, upright forbs and grasses ( Catorci et al. 2015).
