REMARKS. This is one of the smaller Bolivian species of Carineta . It is unique in the lack of significant piceous markings along with the unique structure of the male genitalia.

ETYMOLOGY. The name is in reference to the male claspers that terminate in a hook-like structure (L., uncinatus, hooked).

DESCRIPTION. Ground color of head and thorax dark ochraceous marked with piceous and castaneous, abdomen tawny marked with green in holotype, castaneous marked with piceous in paratype. Green may predominate in fresh specimens as there is a significant proportion of green on tergite 8 of the holotype.

Metanotum ground color with castaneous spot on midline. Short silvery pile between anterior arms of cruciform elevation and anterior sigillae, long silvery pile on posterior mesothorax, radiating from posterior wing groove, and on lateral metanotum, denser in paratype. Ventral thoracic segments ground color except for piceous within basisterna 2 and 3 and castaneous trochantin 2 and 3, covered with long and short silvery pile.

Wings. Fore wings and hind wings hyaline, with eight and six apical cells respectively. Venation ground color becoming darker distally, except piceous curve in anal vein 2 + 3, piceous spot at junction of cubitus anterior 2 and cubitus posterior + anal vein 1, pterostigma present, light linear bronzing in fore wing apical cells of paratype, marginal area beyond apical cells 1–5 radiating lines of infuscation, piceous spot on fore wing base. Basal membrane grayish with darker posterior margin. Hind wing venation greenish-ochraceous becoming darker distally. Anal cell 3 gray, anal cell 2 along proximal anal vein 3, anal cell 3 along anal vein 3 margined with gray. Anal cell 3, posterolateral half of anal cell 2 and along gray area of anal cells 1 and 2, distal anal cell 1 and spot on posterior wing margin infuscated, infuscation expanding into distolateral anal cell 2 of paratype.

Legs. Ground color except castaneous lateral coxae, femoral stripes, dark castaneous spot at base of primary spine in paratype, and distal tibiae, fore tarsi castaneous, middle and hind coxae ground color with castaneous distal pretarsus, pretarsal claws castaneous in middle with piceous tips, long golden pile radiating from legs. Fore femora with proximal spine longest and most oblique, secondary spine upright and of intermediate length, tertiary spine angled greater than and slightly smaller than secondary spine, secondary and tertiary spines curving to tip, very small apical spine emerging from distal base of tertiary spine, spines ground color in middle with castaneous bases and tips, apical spine dark castaneous. Tibial spurs and comb ground color at base becoming castaneous with piceous tips.

Operculum. Male operculum ground color with castaneous spot on lateral base, covered with short silvery pile and radiating longer pile, lateral margin straight, angled mediad to rounded posterior margin to straight posterior margin than angles anteriorly medial to meracanthus to rounded medial margin, not meeting medially, anteromedial margin straight curving to base, not covering tympanal cavity anteromedially, reaching to anterior of sternite II, slightly domed laterally. Meracanthus ground color, broadly triangular with tip curved mediad, just passing anteromedial opercular margin. Female operculum ground color at base, posterior darker, piceous spot on lateral base, with straight lateral margin angled slightly mediad, rounded posterolateral margin to straight posterior margin, medial margin acutely angled with rounded terminus reaching medially to middle meracanthus not covering tympanal cavity, covered with and radiating long golden pile. Female meracanthus broadly triangular, pointed, extending beyond posterior margin of operculum, ground color with piceous lateral margin, radiating long golden pile.

Abdomen. Abdomen tergites tawny, tergite 2 with green posterior and lateral regions, auditory capsule ground color anteriorly becoming castaneous then piceous posteriorly, tergite 3 with green anterolateral margin and green posterior margin, tergites 4–7 with green posterior margin, tergite 8 castaneous with dorsolateral posterior regions and lateral posterior margin green, tergites covered with silvery pile, long silvery pile radiating from lateral tergites 7 and 8. Timbal completely exposed, timbal with eight long ribs and seven intercalary ribs. Female abdominal segment 9 castaneous with piceous fascia on anterior dorsolateral surface, piceous dorsal beak, piceous ventral margin expanding dorsally to encompass stigma, and tawny ventral region, golden pile dorsally and radiating long golden pile ventrally and laterally. Posterior margin of abdominal segment 9 sinuate.

Female sternite VII with deeply curved notch almost reaching anterior margin, lateral posterior margin curving anteriorly from notch to posterolateral terminus.

Genitalia. Male pygofer ground color, dorsal beak dark castaneous, castaneous spot on dorsoanterior base. Dorsal beak narrow, extending to level of anal styles, covered with short and long silvery pile. Pygofer upper lobe small, knob-like. Pygofer basal lobe extended, adpressed to pygofer, curving mediad distally, dense, long golden pile radiating from distal region. Uncus absent, claspers small meeting posterior to anal styles, long golden pile radiating from base. Basal lobe appendage flattened, broad at base curving at right angle to produce extension that splits to form a curved point dorsally and transversely flattened ventral extension with a small spine extending from dorsal side. Aedeagus dark castaneous with two short pseudoparameres.

Female gonapophyses VIII and IX castaneous with piceous tip, gonapophysis X castaneous extending beyond dorsal beak with radiating golden pile. Gonocoxite IX tawny. Anal styles castaneous margined with piceous, about half as long as dorsal beak.

MEASUREMENTS (MM). N = one male and one female. Length of body: male 14.3, female 17.25; length of fore wing: male 18.5, female 22.85; width of fore wing: male 6.7, female 8.0; length of head: male 2.15, female 2.4; width of head including eyes: male 4.7, female 5.15; width of pronotum including suprahumeral plates: male 6.1, female 7.0; width of mesonotum: male 4.95, female 5.45.

DIAGNOSIS. Carineta uncinata n. sp. can be distinguished from most species of Carineta by its small size and lack of significant piceous markings. Similar species in Bolivia are C. garleppi and C. tetraspila but this new species can be distinguished by the mesothorax lacking piceous markings rather than being outlined by piceous. Carineta uncinata n. sp. is also similar to C. pictilis n. sp. but can be distinguished by the lack of piceous mesothoracic markings, reduced prothoracic markings, the lateral pronotum diverging posteriorly rather than being almost parallel, the small castaneous marks on the abdominal sternites, and although the genitalia are similar to C. pictilis n. sp., the base and terminus of the basal lobe appendage differ in that smaller and more heavily marked species. A species of similar size not inhabiting Bolivia is C. tigrina Boulard, 1986a but it can be quickly distinguished by the piceous markings of the pronotum and mesothorax.

DISTRIBUTION. The species is known only from the two specimens of the type series collected near Coroico in La Paz Department.
