TYPE MATERIAL. Holotype. “ PERU: San Martin Dept. / Moyabamba, vic. / Ecológico “ Rumipata ” / 13–18-X-2012 J. E. Eger // S 06º 04’32.0”, W / 076º 58’ 07.5” 970 / m, MV & UV Light” male ( FSCA).

REMARKS. This new species is part of a group of species that are of similar size and general morphology including C. aratayensis , C. cyrili , C. dicrophyrxothrix n. sp., C. dolosa , C. doxiptera , C. ensifera , C. gemella , C. hamata , C. rumipataensis n. sp., C. socia , C. ventrilloni , and C. viridicata . It is one of the smaller species of the group.

ETYMOLOGY. The name is a combination of the common name of the type locality (rumipata -) and - ensis (L., suffix denoting place, locality).

DESCRIPTION. Ground color is ochraceous but fresh specimens are probably green. Color fades to ochraceous in older specimens of originally green species of Carineta .

Head. Head not as wide as mesonotum, ground color without markings. Ocelli rosaceous, eyes ochraceous. Dorsal head radiating dense, long piceous pile, long silvery pile posterior to eye. Gena, lorum, postclypeus and anteclypeus ground color covered with long silvery pile and radiating long piceous pile. Postclypeus centrally sulcate from anterior to posteroventral margin to around apex, with ten transverse ridges, silvery pile on lateral margin, long piceous pile denser on dorsal surface. Mentum ground color, labium ground color with lateral fascia that is castaneous at base becoming piceous distolaterally with castaneous tip, reaching to anterior of hind coxae. Scape, proximal pedicel and annulus on distal pedicel ochraceous, remaining antennal segments castaneous.

Thorax. Dorsal thorax ground color. Pronotum unmarked, mesonotum with castaneous mark in anterior wing groove, metanotum unmarked. Pronotum and mesonotum radiating long piceous pile, long golden pile on mesonotum between anterior arms of cruciform elevation, posterior to anterior arms of cruciform elevation, on lateral and posterior mesothorax, within and radiating from wing groove, and on posterolateral metanotum. Ventral thoracic segments ground color covered with long and short silvery pile.

Wings. Fore wing and wings hyaline, distal half of apical cells lightly bronzed. Venation ground color becoming darker distally. Basal cell hyaline, slightly infuscated at base, pterostigma present, longitudinal lines of infuscation in apical cells, apical cell 1 with a series of tangential lines, and on marginal area of fore wings, basal membrane of fore wing grayish with ground color posterior margin. Hind wing venation ground color becoming darker distally. Anal cell 3 and anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2 grayish, anal cell 3 with ground color posterior margin.

Legs. Legs ochraceous, castaneous on distal trochanter margin, distal tibiae and distal pretarsal claws. Fore femora proximal spine largest, angled to greatest degree, secondary spine slightly angled with curved tip, tertiary spine with slightly curved tip, angled slightly more than secondary spine, all spines castaneous with darker tips, very small piceous apical spine emerging from distal base of tertiary spine. Tibial spurs and combs castaneous with piceous tips. Legs radiating long golden pile. Meracanthus broadly triangular, ground color, reaching middle of medial opercular margin.

Opercula. Male operculum ground color covered with long golden pile, lateral base extended laterally with straight lateral margin, posterior to base lateral margin angled slightly medially, rounded posterolateral and straight posterior margin, slightly widened and rounded medial margin, not meeting medially, reaching medial meracanthus, partially covering tympanum reaching to middle of lateral sternite II, sinuous with right angle laterally when viewed from the posterior.

Abdomen. Abdominal tergites ground color, tergites covered with golden pile, long golden pile surrounding timbal cavity and radiating from auditory capsule. Timbal exposed, white with castaneous ribs, eleven long ribs and ten intercalary ribs. Male sternites and epipleurites ground color with short golden pile and radiating long golden pile.

Genitalia. Male pygofer ground color, dorsal midline and dorsal beak castaneous. Dorsal beak narrow, slightly longer than castaneous anal styles. Pygofer basal lobe about half-length of pygofer, angled laterally at base, angled mediad at right angle in middle with medially rounded apex radiating dense golden pile. Upper pygofer lobes flattened with curved tip, adpressed to pygofer, with dense, very long golden pile emanating from tip. Claspers wide at base straight midline not meeting medially with curved posterior terminus. Basal lobe appendage flattened, semicircular at base, sinuate thin extension from posterior corner, not crossing midline, widening distally, curving at obtuse angle and terminating with two spines, posterior spine longer and larger. Aedeagus tubular, castaneous.

MEASUREMENTS (MM). N = one male. Length of body: 22.85; length of fore wing: 28.65; width of fore wing: 10.10; length of head: 3.90; width of head including eyes: 7.15; width of pronotum including suprahumeral plates: 9.35; width of mesonotum: 7.80.

DIAGNOSIS. This new species is very similar to a group of species that are of similar size and general morphology including C. aratayensis , C. cyrili , C. dicrophryxothrix n. sp., C. dolosa , C. doxiptera , C. ensifera , C. gemella , C. hamata , C. lichiana , C. rumipataensis n. sp., C. socia , C. ventrilloni , and C. viridicata . Carineta acommosis n. sp., C. lichiana and C. modesta are smaller versions with a similar appearance.

The basal pygofer lobe appendage is unique in each species of Carineta . Carineta rumipataensis n. sp. is one of the smaller species of the group along with C. lichiana with body lengths less than 24 mm (although some C. lichiana can be larger). This new species can be distinguished from C. aratayensis , C. dicrophryxothrix n. sp., C. ensifera , C. gemella , C. hamata , C. socia , and C. viridicata by the curved rather than straight posterior margin of the operculum in these species. Carineta gemella and C. lichiana have a contrasting darker abdomen rather than the abdomen the same color as the head and thorax characteristic of C. rumipataensis n. sp. The finger-like medial extension to the operculum in the new species is distinct from the tapering medial extension found in C. cyrili , C. dolosa , C. doxiptera , C. hamata , and C. ventrilloni . In addition, specimens of C. hamata can be quickly distinguished by the piceous stripe on the ventral abdomen.

DISTRIBUTION. The species is known only from the holotype collected in San Martin Department , Peru.
