ETYMOLOGY. The name is a combination of tri - (L. tres, three) and - cuspis (L. cuspis, point, point at the end of anything) in reference to the three points on the basal pygofer lobe appendage of the male.
REMARKS. This is a tawny species marked with piceous that is very similar in general appearance and coloration to Carineta quadrofastigiata n. sp. differing primarily in the shape of the basal pygofer lobe appendage and operculum.
DESCRIPTION. Ground color of head and pronotum tawny, mesonotum and abdomen castaneous marked with piceous. The pronotal collar is greenish-tawny in several paratypes suggesting some tawny regions may be greenish-tawny in fresh specimens.
Head. Head not as wide as mesonotum, ground color, piceous posterior to eye. Ocelli rosaceous, eyes castaneous. Dorsal head radiating dense, long piceous pile, long silvery pile posterior to eye. Ventral head ochraceous. Postclypeus ochraceous ventrally, tawny dorsally, centrally sulcate from anterior to posteroventral margin to apex, with ten transverse ridges, short silvery pile on lateral margin, radiating long piceous pile, denser on dorsal surface. Anteclypeus ochraceous. Ventral head and lateral anteclypeus with short silvery and long white pile, radiating long piceous pile. Mentum ochraceous, labium greenish ochraceous proximally with piceous lateral stripe and distal region, tip castaneous, reaching to anterior of hind coxae. Scape castaneous with tawny distal margin, proximal pedicel tawny, remaining antennal segments castaneous.
Thorax. Dorsal thorax ground color. Pronotum tawny, unmarked, radiating long piceous pile. Pronotal collar ground color, greenish-tawny in some paratypes, radiating long piceous pile. Mesonotum castaneous, cruciform elevation greenish-castaneous in some paratypes, piceous marks outlining submedian sigillae, expanding in posterior of submedian sigilla, expanding along medial margin in paratype, piceous mark anterior to anterior arms of cruciform elevation including scutal depressions laterally, extending anteriorly along midline terminating between posterior submedian sigillae, lateral margin of mesonotum piceous, mark expanding to cover posterior mesonotum, piceous spot on anterolateral wing groove. Metanotum castaneous medially, ochraceous laterally, with piceous spot on anterolateral margin. Long silvery pile between anterior arms of cruciform elevation, posterior to anterior arms of cruciform elevation, on lateral mesothorax, posterior mesothorax, radiating from posterior wing groove, and on posterior metanotum. Long piceous pile radiating from mesothorax. Ventral thoracic segments ochraceous with short silvery and long white pile, radiating long piceous pile on anepisternum 2 and katepisternum 2.
Wings. Fore wings and hind wings hyaline, with eight and six apical cells respectively. Venation ground color, becoming piceous distally, except castaneous radius anterior and subcostal vein distal to node, piceous proximal and castaneous distal anal vein 2 + 3, pterostigma present. Paired linear infuscation in apical cells. Wing margin infuscated, marginal area with linear infuscations appearing to extend from apical cells. Basal membrane grayish. Hind wing venation ground color becoming piceous distally, except castaneous anal vein 2 and anal vein 3. Anal vein 3 very short, about one quarter the length of anal vein 2, forming small anal cell 3 and plaga. Anal cell 3 and plaga gray, anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2 margined with gray. Wing margin infuscated.
Legs. Ground color, greenish-ochraceous in some paratypes, except castaneous tip of distal pretarsus, and distal pretarsal claws, long silvery pile radiating from legs. Fore femora with proximal spine longest, forming an acute angle, secondary spine angled slightly more than primary spine, about as long as tertiary spine, tertiary spine parallel to secondary spine, and very small apical spine emerging from distal base of tertiary spine. Spines castaneous with darker tip. Tibial spurs and comb castaneous with dark castaneous tips. Meracanthus broadly triangular, ochraceous with castaneous posterior base, reaching to middle of medial opercular extension, female meracanthus extending beyond posterior opercular margin.
Opercula. Male operculum ochraceous with castaneous spot on medial and piceous spot on lateral base, medial spot reduced and lateral spot castaneous in some paratypes, covered with long silvery pile, lateral margin curved, bent dorsally on lateral body, sinuate posterior margin, roughly rectangular with finger-like posteromedial extension, rounded medial margin, not meeting medially, not reaching medial to meracanthus, not covering tympanum, reaching to anterior of lateral sternite II, sinuous with right angle laterally when viewed from the posterior. Female operculum of similar shape and color to male except medial extension reaching middle of meracanthus, operculum reaching to anterior of sternite II.
Abdomen. Abdominal tergites ground color with darker castaneous dorsum and piceous posterior margin, tergites covered with short silvery pile, long silvery pile surrounding timbal cavity, long piceous pile radiating from lateral tergites 7 and all of tergite 8. Timbal exposed, white marked with castaneous, only timbal plate visible. Male sternites ground color, darker along midline, radiating silvery pile, epipleurites ground color, with silvery pile. Female tergites and sternites similarly colored to male. Female sternite VII with deep V-shaped medial notch, posterior notch extending as a point beyond arching posterolateral margin. Female abdominal segment 9 ground color with dark castaneous ventral margin, dark castaneous ventroposterior corner, radiating long piceous pile. Dorsal beak about twice as long as ground color anal styles. Posterior margin of abdominal segment 9 curved.
Genitalia. Male pygofer ground color, distal shoulder margin piceous, upper pygofer lobes ochraceous, dorsal beak piceous. Dorsal beak narrow, longer than piceous anal styles. Pygofer basal lobe about half-length of pygofer, angled laterad at base, bent mediad at approximate right angle with medially rounded apex radiating dense golden pile. Upper pygofer lobes adpressed to pygofer, not reaching distal shoulder, bent at approximate right angle near base, with dense long golden pile radiating from posterior margin. Claspers small, curved laterally with straight medial margin with a notch for the aedeagus, forming a knob-like extension dorsally, radiating long golden pile. Basal lobe appendage curving from base meeting on midline then rotating laterally towards tip, with flattened expanded terminus exhibiting three points, a single large extension medially and a lateral extension that has a short point dorsally and a larger point medially, the two larger points form a C-shaped claw when viewed from the ventral side. Aedeagus tubular, castaneous.
Gonocoxite IX castaneous. Female gonapophyses VIII and IX dark castaneous, gonapophysis X piceous extending beyond dorsal beak with radiating piceous pile.
MEASUREMENTS (MM). N = 10 males or two females, mean (range). Length of body: males 16.34 (15.05–16.80), females 16.98 (16.55–17.40); length of fore wing: males 20.80 (19.35–21.70), females 21.00 (20.95–21.05); width of fore wing: males 7.31 (6.65–7.90), females 7.30 (7.15–7.45); length of head: males 3.02 (2.90–3.35), females 2.85 (2.80–2.90); width of head including eyes: males 5.43 (5.10–5.55), females 5.35 (5.25–5.45); width of pronotum including suprahumeral plates: males 6.52 (6.20–7.00), females 6.60 (6.50–6.70); width of mesonotum: males 5.55 (5.35–5.50), females 5.43 (5.35–5.50).
DIAGNOSIS. This is another of the few species of small Carineta that possess mesothoracic markings and lack prothoracic markings including C. digitata n. sp. and C. quadrofastigiata n. sp. Carineta digitata n. sp. can be distinguished by the primarily castaneous abdomen, markings on the medial submedian sigillae margin, the parallel fore femora spines, and the two finger-like extensions on the end of the basal pygofer lobe appendage found in this species. Similarly, C. quadrofastigiata n. sp. can be distinguished by the expanded piceous markings on the anterior and lateral mesothoracic margins, the lateral margin of the timbal forms a right angle with the posterior timbal margin when viewed from the posterior, and the four points on the terminus of the basal pygofer lobe appendage found in this species.
DISTRIBUTION. The species is known from several localities in Peru.
