( Fig. 14 )

TYPE MATERIAL. Holotype. “ PERU. Loreto / Tingo Maria / 9 Feb. 1977 / J. R. Robertson // LACM ENT 403496 ” male ( LACM) . Paratypes. “ PERU. Loreto / Tingo Maria / 9 Feb. 1977 / J. R. Robertson // LACM ENT 403453 ” one male ( LACM); “Peru / Tingo Maria / H. & M. Cohen Coll. / 1981 Feb. 20 ” one male ( BNSN); “ Peru / Tingo Maria / Feb. 21, 1981 ” one male ( BNSN); “Peru / Tingo Maria / Feb. 16, 1981 ” one male ( AFSC) .

REMARKS. Carineta tingomariaensis is most similar to C. acommosis n. sp.,. C. apicalis , C. maracayensis , C. modesta , C. naponore , and C. spoliata . It is another small to medium sized non-descript species. The bronzing is very light and restricted to the distal half of the fore wing apical cells in this new species.

ETYMOLOGY. The name is a combination of the common name of the type locality (tingomaria -) and - ensis (L., suffix denoting place, locality) in reference to the type locality of the species.

DESCRIPTION. Ground color testaceous, probably green in fresh specimens as color fades in older specimens of other species of Carineta . Abdomen partially or mostly castaneous in some specimens but appears to be an artifact as the color is not uniform.

Head. Head not as wide as mesonotum, ground color without markings. Ocelli rosaceous, lateral ocelli faded to ochraceous in holotype, ochraceous in some paratypes. Eyes castaneous. Head covered with dense, long, piceous pile radiating from dorsal head, long silvery pile posterior to eye. Ventral head ground color with short silvery pile and dense, long white pile. Postclypeus ground color, centrally sulcate from anterior to posteroventral margin to around apex, with twelve transverse ridges, short silvery pile on lateral margin, long piceous pile radiating from dorsal and ventral surfaces, denser on dorsal surface. Anteclypeus ground color with short silvery pile, radiating dense, long white pile and long piceous pile. Mentum ground color, labium tawny proximomedially with lateral fascia that is castaneous at base becoming piceous distally with castaneous tip, reaching to anterior of hind coxae. Antennal segments castaneous except ground color proximal scape, distal scape, and proximal pedicel.

Thorax. Dorsal thorax ground color with radiating long piceous pile, some dark stippling in sigillae of some paratypes where muscle attaché internally. Mesonotum covered with long silvery pile on lateral and posterior mesothorax, within and radiating from wing groove, and on posterior metanotum. Ventral thoracic segments ground color covered with short silvery and dense, long white pile, sparse, long piceous pile on anepisternum 2.

Wings. Fore wing and wings hyaline, distal half of apical cells lightly bronzed. Venation ground color becoming darker distally. Basal cell hyaline, pterostigma present, longitudinal lines of infuscation in distal apical cells, and on marginal area of fore wings, basal membrane of fore wing grayish with piceous posterior margin. Hind wing venation ground color becoming darker distally, castaneous spot on base of anal veins 2 and 3, anal vein 3 less than half as long as anal vein 2 with curved distal terminus. Anal cell 3 and anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2 grayish, anal cell three with piceous posterior margin.

Legs. Legs ground color except castaneous distal tibiae, proximal and distal tarsi, and proximal pretarsal claws, pretarsal claws with piceous tips. Fore femora proximal spine largest, acutely angled to greatest degree, secondary spine perpendicular to femoral axis with curved terminus, intermediate in length, tertiary spine parallel to primary spine, all spines ground color with castaneous tips. Tibial spurs and combs castaneous. Legs with long white pile on coxae, long castaneous pile on distal fore femora and proximal fore tibiae, radiating long silvery pile on remaining segments. Meracanthus broadly triangular, ground color, reaching middle of medial opercular extension.

Opercula. Male operculum ground color covered with long golden pile, long silvery pile at base, lateral margin straight, parallel to long body axis, extended rounded posterolateral margin and sinusoidal posterior margin, base roughly rectangular with hemispherical extension posterolaterally and a finger-like extension angled posteromedially from posteromedial region, rounded medial margin, not meeting medially, reaching to lateral coxa, not covering tympanal cavity completely, reaching to posterior of lateral sternite II, right angled laterally with sinuous posterior margin when viewed from the posterior.

Abdomen. Abdominal tergites ground color, castaneous in some paratypes, tergites covered with golden pile, denser on lateral tergites 2–3, long piceous pile on dorsum of tergites 2–6, long golden pile surrounding timbal cavity and radiating from tergites, denser on lateral tergites 6–7 and all of dorsal tergite 8. Timbal exposed, white with castaneous ribs, six long ribs visible. Male sternites and epipleurites ground color radiating long silvery pile, sternite VIII V-shaped when viewed from the posterior, radiating long castaneous pile.

Genitalia. Male pygofer ground color, castaneous in one paratype, dorsal beak darker. Dorsal beak narrow, longer than piceous anal styles. Pygofer basal lobe about half-length of pygofer, angled laterad at base, curving mediad and expanding to medially rounded apex, radiating dense, long golden pile. Upper pygofer lobes adpressed to pygofer, short, flattened, bent posteromedially at base. Claspers with straight lateral margin, with short, knob-like, rounded medioposterior prior to terminus. Basal lobe appendage flattened, curving and narrowing posteriorly, not crossing midline, bifurcating near terminus to form two sharp points. Aedeagus tubular, castaneous.

Female is unknown.

MEASUREMENTS (MM). N = five males, mean (range). Length of body: 18.08 (17.45–18.95); length of fore wing: 24.83 (24.20–25.95); width of fore wing: 8.83 (8.40–9.25); length of head: 3.45 (3.35–3.70); width of head including eyes: 6.00 (5.85–6.20); width of pronotum including suprahumeral plates: 8.15 (8.10–8.30); width of mesonotum: 6.80 (6.55–6.95).

DIAGNOSIS. Carineta tingomariaensis is most similar to C. acommosis n. sp., C. apicalis , C. maracayensis , C. modesta , C. naponore , and C. spoliata . It is a smaller version of the species group composed of 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 that have a similar general appearance but larger body size (> 25 mm).

This new species can be distinguished from C. acommosis n. sp., C. modesta , and C. spoliata by narrower posterior prothorax and the parallel sides of the abdomen in these species. In addition, the frons is at an approximate right angle to the vertex in C. acommosis and C. modesta . This new species can be distinguished from C. apicalis and C. naponore by the abdomen tapering toward the posterior in these species and the basal lobe appendages are large flattened lobes in C. apicalis , similar but smaller lobes in C. naponore and short and curving to a point in C. tingomariaensis n. sp.

The most similar species is C. maracayensis from Venezuela. This new species can be distinguished by the finger-like extension of the posterior male operculum beind a straight continuation of the posterior opercular margin, the eight timbal ribs, and the basal pygofer lobe appendage forming a single sharp point in C. maracayensis .

DISTRIBUTION. The species is known only from the type series collected in Loreto Department, Peru.
