REMARKS. Carineta acommosis n. sp. is most similar to C. apicalis Distant, 1883, C. maracayensis Sanborn 2020a, C. modesta Sanborn, 2011a, C. naponore Boulard, 1986a, C. spoliata (Walker, 1858a), and C. tingomariaensis n. sp. It is a small to medium sized non-descript species.
ETYMOLOGY. The name is a combination of a - (Gr. a -, not, without) and - commosis (Gr., kommosis, ornamentation) in reference to the lack of markings in the species.
DESCRIPTION. Ground color of head and thorax is green, abdomen varies from greenish, greenish-ochraceous, ochraceous to tawny or a combination. Green fades to ochraceous in older specimens.
Head. Head not as wide as mesonotum, ground color without markings. Ocelli ochraceous, greenish or margined with rosaceous in some paratypes. Eyes castaneous. Head covered with silvery pile, longer posterior to eye, long, piceous pile between ocelli, extending laterally while decreasing in density to anteromedial eye continuing on anterolateral vertex anterior to eye and terminating posterior to supra-antennal plate, density of piceous pile reduced in some paratypes. Gena and lorum ground color covered with long silvery pile. Postclypeus ground color, centrally sulcate from anterior to posteroventral margin to around apex, with ten transverse ridges, short silvery pile on lateral margin, long piceous pile radiating from dorsal and ventral surfaces. Anteclypeus ground color with long silvery pile, radiating long piceous pile. Mentum ground color, labium ground color with distal lateral fascia that is castaneous surrounding piceous, reaching to anterior of hind coxae. Scape and proximal pedicel ochraceous, remaining antennal segments castaneous.
Thorax. Dorsal thorax ground color. Pronotum covered with short silvery pile, longer pile radiating from lateral part of pronotal collar. Mesonotum ground color, parapsidal suture slightly darkened in some paratypes, mottling within submedian and lateral sigillae where muscles attach internally in some paratypes, lighter or darker in various paratypes, with radiating silvery pile. Metanotum ground color. Mesonotum covered with short silvery pile, long silvery 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 laterally, ochraceous medially, covered with long and short silvery pile.
Wings. Fore wing and wings hyaline, lightly bronzed in apical cells. Venation ground color becoming castaneous distally. Basal cell hyaline, pterostigma present, longitudinal lines of infuscation in apical cells, apical cell 1 with a series of tangential lines, and on marginal area of fore wings, basal membrane of fore wing grayish with ground color 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 with ground color posterior margin.
Legs. Legs ochraceous, darkening distally, some paratypes with greenish proximal tibiae, femora lightly striped with castaneous, pretarsal claws ochraceous at base becoming castaneous with piceous tips. Fore femora proximal spine straight, largest, angled, secondary spine parallel to primary spine at base curved distal half, tertiary spine angled to greatest degree at base with more strongly curved tip, all spines castaneous with darker tips. Tibial spurs and combs castaneous with darker tips. Legs radiating long golden pile on remaining segments. Meracanthus broadly triangular, lateral margin smoothly curved, ground color, reaching middle of medial opercular margin, female meracanthus extending slightly beyond posterior opercular margin.
Opercula. Male operculum ground color covered with short silvery, radiating long silvery pile from posterior margin, lateral margin straight, slightly angled medially, rounded posterolateral margin, posterior margin straight forming an obtuse angle with lateral margin, rounded medial margin, not meeting medially, not reaching medial meracanthus, barely covering tympanum reaching to middle of lateral sternite II, domed laterally. Female operculum and meracanthus similarly shape and color, operculum reaching to middle of sternite II.
Abdomen. Abdominal tergites tawny, varying from greenish to greenish anteriorly and tawny posteriorly to ochraceous in paratypes, posterior margin darker in holotype, greenish or same color as tergites in various paratypes, tergites covered with silvery pile, long silvery pile surrounding timbal cavity and radiating from auditory capsule. Timbal exposed, white with castaneous ribs, six long ribs and five intercalary ribs. Male sternites castaneous in holotype, green, ochraceous or partially castaneous in paratypes, posterior midline of sternite IV, medial sternite V and medial region of sternite VI castaneous, sternite VII castaneous with dark ochraceous posteromedial region expanding posteriorly to margin, sternite VIII ground color with transverse posterior margin, short golden pile radiating from sternites, epipleurites ground color becoming castaneous in posterior segments, castaneous reduced or absent in some paratype, covered with golden pile. Female tergites ochraceous anteriorly becoming tawny posteriorly with green posterior margin, sternites similarly colored to male, sternite VII light castaneous. Female sternite VII with deep V-shaped medial notch anteriorly, extending with parallel sides to triangular extension of posterior notch beyond arching posterolateral margin. Female abdominal segment 9 greenish-ochraceous with light castaneous ventral margin, radiating long silvery pile, denser on ventral surface. Dorsal beak with castaneous tip, twice as long as ground color margined with castaneous anal styles. Posterior margin of abdominal segment 9 smoothly curved.
Genitalia. Male pygofer tawny in holotype, green, ochraceous or castaneous in paratypes, dorsal beak with castaneous tip. Dorsal beak narrow, longer than anal styles which are same color as pygofer with castaneous margins. Pygofer basal lobe about half-length of pygofer, angled mediad, radiating dense golden pile. Upper pygofer lobes elongated, with ventral concavity, bent at approximate right angle near base with triangular tip, distally with dense long golden pile. Claspers wide at base convex ventral surface radiating long golden pile, with short, diverging termini. Basal lobe appendage wide at base, flattened, crossing across midline, narrowing to acuminate, bifurcated tip. Aedeagus tubular, dark castaneous.
Female gonocoxite IX ground color with light castaneous medial margin. Gonapophysis IX dark castaneous, gonapophysis X ground color medially, castaneous laterally. Ovipositor sheath extends beyond dorsal beak. Long silvery pile radiating from ovipositor sheath.

DIAGNOSIS. Carineta acommosis n. sp. is most similar to C. apicalis Distant, 1883, C. maracayensis Sanborn 2020a, C. modesta Sanborn, 2011a, C. naponore Boulard, 1986a, C. spoliata (Walker, 1858a), and C. tingomariaensis n. sp. It is a smaller version of the species group composed of C. aratayensis Boulard, 1986a, C. cyrili Champanhet, 1999, C. dicrophryxothrix n. sp., C. dolosa Boulard, 1986a, C. doxiptera Walker, 1858a, C. ensifera Sanborn, 2019b, C. gemella Boulard, 1986a, C. hamata Sanborn 2019b, C. lichiana Boulard, 1986a, C. rumipataensis n. sp., C. socia Uhler, 1875, C. ventrilloni Boulard, 1986a, and C. viridicata Distant, 1883 that have a similar general appearance but larger body size (> 25 mm).
This new species can be distinguished from C. apicalis, C. naponore, and C. tingomariaensis n. sp. by the finger-like medial extension of the male operculum and the broader posterior prothorax producing a more triangular anterior, the frons is not at an approximate right angle to the vertex and the abdomen tapers toward the posterior in C. apicalis and C. naponore, and the basal lobe appendages are large flattened lobes in C. apicalis, similar by smaller lobes in C. naponore and short and curving to a point in C. tingomariaensis n. sp. Carineta maracayensis can be distinguished by the radiating piceous pile, the proportionately wider posterior prothorax, the finger-like extension of the medial male operculum, the curving sides of the basal abdomen, and the single point of the basal pygofer lobe appendage. Carineta modesta is smaller (body size about 19 mm), with basal pygofer lobes that are elongated and terminating in a single point. Finally, C. spoliata can be distinguished by the slightly smaller body size, the female operculum is approximately square with a medial extension instead of triangular, the longer and thinner tertiary spine of the fore femora, and the wider notch in female sternite VII that terminates in a triangular extension rather than a curved medial margin to the extension tip like in the new species.
DISTRIBUTION. The species is known only from the type series collected from several localities in Bolivia, Brazil, Ecuador and Peru.
