REMARKS.— Carineta tiarata n. sp. is a small to medium sized dichromatic species with a curved marking on the head. The type locality is now part of Guayas Province, Ecuador.

ETYMOLOGY.—The name tiarata (Gr. tiarata , turbaned, tiara) in reference to the tiara shaped marking on the frons and vertex in this species.

DESCRIPTION

Ground color of head and thorax is ochraceous, probably green in live or fresh specimens, and a castaneous abdomen. The only marking is a curved marking on the frons and vertex of the head.

Head

Head not as wide as mesonotum, ground color with dark castaneous frons, castaneous marks extending posterolaterally from frons to encircle all but posterior lateral ocelli, mark terminates in posterior cranial depression, mark extends laterally to medial margin of eye, expanding on posterior eye, marks expanded or reduced in paratypes but tiara shaped mark always present. Ocelli rosaceous, eyes dark castaneous. Head covered with short golden pile, longer and denser silvery posterior to eye, long, piceous pile radiating from dorsal head. Gena castaneous with ground color margin with anterior lorum, lorum castaneous with ground color anterior margin and anterolateral corner, covered with short golden and long silvery pile. Postclypeus ground color with castaneous transverse ridges, castaneous fascia connecting medial transverse ridges, centrally sulcate from anterior to posteroventral margin to around apex, with eleven transverse ridges, short silvery pile on lateral margin, sparse, long piceous pile radiating from dorsal and ventral surfaces. Anteclypeus castaneous with ground color anterior margin and carina, ground color expanded in some paratypes, carina with a pair of castaneous spots posterior to middle, with short golden and long silvery pile. Mentum ground color, labium ground color with distal castaneous lateral fascia not reaching tip, rostrum reaching to posterior of hind coxae. Antennal segments castaneous.

Thorax

Dorsal thorax ground color. Pronotum covered with short golden pile and radiating longer piceous pile. Mesonotum ground color, parapsidal suture slightly darkened in some paratypes, mottling within submedian and lateral sigillae where muscles attach internally in some paratypes, scutal depressions, along anterior arms of cruciform elevation and posterior mesonotum all castaneous, marks reduced in some paratypes. Metanotum ground color with castaneous spot on anterolateral corner. Mesonotum covered with short golden pile, long golden pile 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 except castaneous basisternum 2, trochantin 2, meron 2, posterior anepimeron 2, anteromedial and posteromedial katepimeron 2, trochantin 3, and basisternum 3, covered with long and short golden pile, long piceous pile radiating from anepisternum 2, katepisternum 2, and trochantin 2.

Wings

Fore wing and wings hyaline, lightly bronzed. Venation ground color becoming castaneous distally, cubitus posterior + anal vein 1, anal vein 2+3, and castaneous spot on base of cubitus anterior. Basal cell clouded, pterostigma present, longitudinal lines of infuscation in apical cells, and on marginal area of fore wings, basal membrane of fore wing grayish with darker 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 mottled with red in some paratypes.

Legs

Legs castaneous except ground color medial coxae, anteromedial trochanter, distal femora, proximal tibiae, piceous mark on anterolateral coxae, distal pretarsal claws piceous. Fore femora proximal spine straight, largest, most acutely angled, secondary spine curved narrower, about half the length of primary spine, tertiary spine angled almost as much as primary spine, about as long as secondary spine, all spines castaneous with lighter tips, and very small, castaneous apical spine. Tibial spurs and combs castaneous with darker tips. Coxae with short golden pile, remaining leg segments radiating long golden pile. Meracanthus broadly triangular, ground color with castaneous base, reaching anterior margin of medial operculum in male, female meracanthus extending beyond posterior opercular margin.

Opercula

Male operculum ground color with large castaneous spot on anterolateral base, expanding over anterior operculum in some paratypes, covered with short golden pile, radiating long golden pile especially from posterior margin, lateral margin with a slight rectangular lateral extension at base, smoothly curved lateral, posterolateral and posterior margins, rounded medial margin, not meeting medially, not reaching medial margin of tympanal cavity, barely covering tympanum posteriorly reaching to anterior of lateral sternite II, anteromedial margin smoothly curved, not covering tympanal cavity. Female operculum and meracanthus similarly shaped and colored except medial extension more acuminate, operculum reaching to anterior of sternite II, medially not reaching medial meracanthus.

Abdomen

Abdominal tergites dark castaneous with piceous lateral spots, piceous marks on anterior dorsolateral tergite 8, tergites covered with golden pile, dense surrounding timbal cavity and radiating from piceous auditory capsule, radiating from tergite 8. Timbal exposed, white with castaneous ribs, six long ribs and five intercalary ribs. Sternites dark castaneous, male sternites VII and VIII with transverse posterior margins, long golden pile radiating from sternites, epipleurites dark castaneous radiating long golden pile. Female tergites and epipleurites as in male. Female sternite VII with deep U-shaped medial notch anteriorly, diverging posteriorly to triangular extension of posterior notch beyond arching posterolateral margin. Female abdominal segment 9 dark castaneous with ground color marks anteroventrally and ventral to stigma, radiating long golden pile, denser on ventral and lateral surfaces. Castaneous dorsal beak curving dorsally, about twice as long as castaneous anal styles. Posterior margin of abdominal segment 9 smoothly curved.

Genitalia

Male pygofer dark castaneous, dorsal beak with castaneous tip. Dorsal beak narrow, longer than castaneous anal styles. Pygofer basal lobe about half-length of pygofer, curving mediad, radiating dense golden pile. Upper pygofer lobes small, knob-like. Claspers wide at base, termini narrowed, tooth-like, diverging laterally. Basal lobe appendage wide at base, flattened, not crossing midline, angled posteriorly, sword-like, with ventral margin curved to tip. Aedeagus tubular, dark castaneous.

Female gonocoxite IX, gonapophysis IX and gonapophysis X castaneous, distal gonapophysis IX piceous. Ovipositor sheath extends beyond dorsal beak. Long golden pile radiating from ovipositor sheath.

MEASUREMENTS (MM).—N = five males or five females, mean (range). Length of body: males 19.05 (18.55– 19.80), female 20.65 (19.50–22.00); length of fore wing: males 24.40 (24.15–25.15), female 25.62 (24.05–26.45); width of fore wing: males 9.10 (8.90–9.40), female 9.51 (8.80–9.85); length of head: males 3.24 (3.15–3.35), female 3.28 (3.05–3.45); width of head including eyes: males 6.42 (6.20–6.55), female 6.54 (6.30–6.75); width of pronotum including suprahumeral plates: males 8.25 (8.00–8.60), female 8.33 (7.70–8.75); width of mesonotum: males 7.19 (6.95–7.40), female 7.33 (6.80–7.70).

DIAGNOSIS.—The body shape, lack of anterior extension of the postclypeus forming a triangular head, and the contrasting abdominal coloration separate this new species from most in the genus. Only C. ecuatoriana , C. strigilifera and C. titschacki have the non-prominent head and basic coloration patterns similar to this new species. The new species can be distinguished from C. titschacki by the fascia outlining the submedian sigillae. Carineta tiarata n. sp. is most similar to C. strigilifera in general appearance but that species has a rostrum that reaches to the posterior trochanters, the triangular opercula, a dorsal beak extending only as long as the anal styles, and the basal lobe appendage that is curved at an approximate right angle with a transverse terminus forming two points on the distal corners rather than the sword-like basal lobe appendage with the ventral margin curved to the tip of the new species. Carineta ecuatoriana also has a similar general appearance (illustrated in Goding (1925)) but can be distinguished quickly by the infuscation that is restricted to the fore wing and hind wing marginal area distal to apical cells 1–3, the longitudinal infuscation in the apical cells that are restricted to the distal apical cells, and are found on the entire marginal area of both the fore and hind wings in C. ecuatoriana .

DISTRIBUTION.—The species is known only from the type series collected Bolivar Province and two localities in Guayas Province, Ecuador.
