TYPE MATERIAL. Holotype. “ Santa Cruz, Bolivia / Buena Vista elev. 350m / near Hotel Flora & Fauna / Nearns,Morris&Wappes— 11/15/03 ” male ( FSCA).

REMARKS. This is a small species of Carineta with extensive markings.

ETYMOLOGY. The name is in reference to the thoracic markings of the species (L., pictilis , colored, painted, embroidered).

DESCRIPTION. Ground color tawny marked with castaneous and piceous.

Head. Head not as wide as mesonotum, tawny, piceous medially except for small tawny triangle on posterior margin, piceous expands anterolaterally along medial supra-antennal plate and posterolaterally to enclose posterior cranial depression, eye margined with piceous. Head covered with short silvery pile dorsally, radiating long golden pile, longer and denser silvery posterior to eye. Ocelli rosaceous, eyes castaneous. Ventral head piceous except tawny medial and posterior on gena. Postclypeus centrally sulcate, tawny except castaneous within central sulcus, eleven transverse ridges and dorsal surface, radiating long golden pile. Anteclypeus piceous with castaneous carina with piceous spots on either side of middle of carina. Long silvery pile on lorum, gena, lateral postclypeus and anteclypeus. Mentum tawny, labium castaneous becoming piceous distally. Rostrum reaching to anterior of posterior coxae. Scape, proximal pedicel, distal annular mark on pedicel tawny, remaining antennal segments piceous.

Thorax. Dorsal thorax tawny marked with castaneous and piceous. Prothorax with tawny, castaneous fascia on either side of midline fusing anteriorly and posteriorly, anterior lateral disc castaneous, piceous in anterior half of lateral fissure, on central lateral disc, on dorsolateral disc and piceous fascia medial to posterior lateral fissure recurving mediad from posterior, sparse silvery pile in fissures. Pronotal collar tawny, sparse silvery pile on lateral angle. Mesothorax tawny, castaneous spot on anterolateral margin, lateral sigillae castaneous with piceous anterior margin, castaneous extending and curving laterad onto disc almost reaching posterior curve, submedian sigillae piceous, castaneous between and posterior submedian sigillae with mark extending to between anterior arms of cruciform elevation, scutal depressions piceous, and castaneous posterolateral and posterior. Sparse silvery pile on dorsum, longer and denser in wing groove and on posterior margin. Metanotum tawny with silvery pile on posterior margin. Ventral thoracic segments tawny with piceous marks on basisternum 2, lateral trochantin 2, meron 2, basisternum 3, medial episternum 3, and trochantin 3. Thoracic sternites covered with dense silvery pile.

Wings. Fore wing and wings hyaline with eight and six apical cells respectively. Venation tawny-ochraceous at base becoming darker distally except piceous along basal cell anteriorly at base and piceous proximal half of anal vein 2 + 3, pterostigma present, basal membrane of fore wing grayish with darker posterior. Hind wing venation coloration similar to fore wing. Anal cell 3, anal cell 2 along anal veins 2 and 3, and anal cell 1 along anal vein 2 grayish, infuscation along gray in anal cell 2 and anal cell 1, distal anal cell 2 and marginal area of hind wing along anal cell 1.

Legs. Legs tawny, anterior and posterior coxae, marks on anterior and posterior trochanters, femora except distal margin, distal half of fore tibiae, distal middle tibiae, fore tarsi, distal half of middle pretarsus, and distal margin of hind pretarsus castaneous, pretarsal claws ground color at base, becoming castaneous with piceous tips. Fore femora with proximal spine largest, angled, secondary spine less angled and smaller than primary spine with curved posterior, tertiary spine smaller, with greatest angle, and small triangular apical spine extending from tertiary spine base, all spines piceous at base becoming castaneous with lighter area proximal to tip. Tibial spurs and combs dark tawny with castaneous tips. Legs with long silvery pile.

Operculum. Male operculum tawny with castaneous spot on lateral base, piceous on proximal lateral margin becoming castaneous, covered with short silvery pile radiating long silvery pile, lateral margin straight angled mediad posterior to base, rounded posterolateral margin, posterior margin straight to semicircular medial margin, not meeting medially, anteromedial margin smoothly curved to base, not covering tympanum posteriorly or anteromedially, not reaching to anterior of sternite II, domed laterally. Meracanthus broadly triangular, pointed, tawny with castaneous base, extending posteriorly to anteromedial opercular margin.

Abdomen. Abdomen tergite 1 tawny, light castaneous laterally, tergite 2 tawny, castaneous medially, piceous spot on anterodorsal surface adjacent to timbal cavity, piceous spot in middle of margin to timbal cavity, piceous auditory capsule, posterior margin castaneous with piceous dorsum, tergite 3 castaneous with piceous posterior and lateral margins and tawny anterolateral spot, tergite 4 piceous anteriorly and laterally, castaneous posteriorly, tergite 5 dark tawny piceous lateral surfaces and piceous dorsolateral surface on right side, tergites 6–8 tawny with piceous anterior margin and lateral portions, castaneous on dorsoposterior midline, tergites covered with silvery pile, long silvery pile on ventrolateral tergites 7 and 8. Timbal completely exposed with nine long and eight intercalary ribs. Male sternites I and II castaneous with tawny posterior, sternite III dark tawny anteriorly, castaneous posteriorly, sternites IV and V castaneous with darker posterior margin, sternite VI piceous, sternite VII piceous anteriorly, castaneous posteriorly, sternite VIII castaneous with open U-shaped notch posteriorly, epipleurites 3–5 castaneous, epipleurite 6 tawny anteriorly, castaneous posteriorly, epipleurite 7 piceous, sternites and epipleurites with silvery pile, longer pile radiating from sternites, epipleurites piceous.

Genitalia. Male pygofer tawny, dorsal beak and anterolaterally castaneous, castaneous spot on dorsoanterior base, piceous surrounding base of dorsal beak, dorsolateral surface with silvery pile. Dorsal beak narrow, extending to level of anal styles, radiating long silvery pile. Pygofer upper lobe small, knob-like. Pygofer basal lobe extended, adpressed to pygofer, curving mediad distally, radiating long golden pile, denser distally and medially. Uncus absent, claspers small meeting posterior to anal styles, long golden pile radiating from base. Basal lobe appendage flattened, expanding from base, curving at right angle to produce flattened extension that splits to form a curved point ventrally and a dorsal extension that splits to form a claw-like structure with the ventral extension and a small triangular spine extending from dorsal side. Aedeagus dark castaneous with two short pseudoparameres.

Female is unknown.

MEASUREMENTS (MM). N = one male. Length of body: 14.3; length of fore wing: 18.5; width of fore wing: 6.7; length of head: 2.15; width of head including eyes: 4.7; width of pronotum including suprahumeral plates: 6.1; width of mesonotum: 4.95.

DIAGNOSIS. Carineta pictilis n. sp. can be distinguished from most species of Carineta by its small size and piceous markings. The most similar species in Bolivia are C. garleppi and C. tetraspila but can be distinguished by the smaller body size and mesothoracic sigillae being completely or mostly filled with piceous in the new species rather than being outlined by piceous along with the piceous markings on the abdominal tergites of the new species. Carineta uncinata n. sp. is slightly larger and 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. uncinata n. sp., the base and terminus of the basal lobe appendage differ in that larger and less marked species. A species of similar size not inhabiting Bolivia is H. tigrina ( Boulard, 1986a) n. comb. but it can be quickly distinguished by the piceous markings of the pronotum ambient fissure and the submedian sigillae are surrounded by piceous and the head being wider than the mesonotum in this species.

DISTRIBUTION. The species is known only from the holotype collected near Buena Vista.
