Etymology. The name is a combination of maracay – and – ensis (L. suffix denoting place, locality) in reference to the type locality of the species.
Remarks. This is a monochromatic species of Carineta that is very similar in general appearance but differs in the size and basal pygofer lobe appendage from a number of species of Carineta including C. acommosis Sanborn, 2020, C. apicalis Distant, 1883a, C. modesta Sanborn 2011a, C. naponore Boulard, 1986, C. spoliata Walker, 1858a, and C. tingomariaensis Sanborn, 2020.
Description
Ground color of head and thorax testaceous, probably green in fresh specimens as color fades to a similar color in older specimens of other Carineta species, with a castaneous abdomen.
Head. Head not as wide as mesonotum, ground color without markings. Ocelli rosaceous, faded to ochraceous in holotype and one paratype. Eyes castaneous. Head covered with short silvery pile, longer posterior to eye, dense, long, piceous pile radiating from dorsal head. Ventral head ground color with short silvery pile and dense, long white pile. Postclypeus ground color, centrally sulcate from anterior to posteroventral margin to around apex, with eleven transverse ridges, short silvery pile on lateral margin, long piceous pile radiating from dorsal and ventral surfaces, denser on dorsal surface. Anteclypeus ground color with short silvery pile, radiating dense, long white pile. Mentum ground color, labium ground color with lateral fascia that is castaneous at base becoming piceous distally with castaneous tip, reaching to anterior of hind coxae. Antennal segments castaneous except ground color proximal scape, distal scape, and proximal pedicel.
Thorax. Dorsal thorax ground color with radiating long piceous pile, some paratypes with castaneous parapsidal suture. Mesonotum covered with long silvery pile on lateral and posterior mesothorax, within and radiating from wing groove, and on posterior metanotum. Ventral thoracic segments ground color covered with short silvery and dense, long white pile. A few long piceous pile on anepisternum 2.
Wings. Fore wings and hind wings hyaline, distal half of apical cells lightly bronzed. Venation ground color becoming darker distally. Basal cell hyaline, pterostigma present, longitudinal lines of infuscation in distal apical cells, and on marginal area of fore wings, basal membrane of fore wing grayish. Hind wing venation ground color becoming darker distally, castaneous spot on base of anal veins 2 and 3, anal vein 3 about half as long as anal vein 2 with curved distal terminus. Anal cell 3 and anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2 grayish.
Legs. Legs ground color except castaneous distal tibiae, proximal and distal tarsi, and proximal pretarsal claws, pretarsal claws with piceous tips. Fore femora proximal spine largest, acutely angled to greatest degree, secondary spine almost perpendicular to femoral axis, intermediate in length, tertiary spine angled more than secondary spine with slightly curved tip, all spines ground color with castaneous tips. Tibial spurs and tibial combs castaneous. Legs with long white pile on coxae, radiating long silvery pile on remaining segments. Meracanthus broadly triangular, ground color, reaching middle of medial opercular extension, female meracanthus of similar shape, extending beyond posteromedial opercular margin but not as long as lateral operculum.
Opercula. Male operculum ground color covered with long golden pile, long silvery pile at base, lateral margin straight, parallel to long body axis, rounded posterolateral margin and sinusoidal posterior margin, base roughly rectangular with finger-like extension angled posteromedially from posteromedial region, rounded medial margin, not meeting medially, reaching to middle of coxae, not covering tympanal cavity completely, reaching posteriorly to middle of lateral sternite II, right angled laterally with sinuous posterior margin when viewed from the posterior. Female operculum of similar shape and color to male except medial extension much smaller reaching only to middle of meracanthus, operculum reaching to posterior of sternite II.
Abdomen. Abdominal tergites castaneous, tergites covered with golden pile, denser long silvery pile on lateral tergites 2–5, long piceous pile on dorsum of tergites 2–6, long golden pile surrounding timbal cavity and radiating from tergites, denser on lateral tergites 6–7 and all of dorsal tergite 8. Timbal exposed, white with eight long castaneous ribs. Male sternite I and II ground color with castaneous posterior, sternites III–VIII castaneous with darker posterior margins in sternites III–V in holotype, absent in paratypes, sternites with short silvery pile and radiating long golden pile, sternite VIII castaneous with short silvery pile and long castaneous pile radiating from sternites. Epipleurites colored like sternites with similar pile. Female tergites and sternites similarly colored to male, piceous pile on dorsum of tergites 2–8. Female sternite VII with deep medial notch, open V-shaped anteriorly with long parallel sides posteriorly, posterior notch extending with a lateral curve beyond arching posterolateral margin. Female abdominal segment 9 ground color with lighter ventral margin, radiating long piceous pile. Dorsal beak dark castaneous, longer than piceous anal styles. Posterior margin of abdominal segment 9 curved.
Genitalia. Male pygofer castaneous, dorsal beak darker. Dorsal beak narrow, longer than piceous anal styles. Pygofer basal lobe about half-length of pygofer, angled laterad at base, curving mediad and expanding to medially rounded apex, radiating dense, long golden pile. Upper pygofer lobes adpressed to pygofer, short, flattened, angled posteromedially. Claspers with straight lateral margin and short, knob-like, rounded medioposterior terminus. Basal lobe appendage flattened, curving and narrowing posteriorly, not crossing midline, termini curved laterad, forming a sharp point. Aedeagus tubular, castaneous.
Female gonocoxite IX darkened ground color. Gonapophysis IX castaneous, gonapophysis X piceous. Ovipositor sheath extends beyond dorsal beak. Long golden pile radiating from ovipositor sheath.
Measurements (mm). N = ten males or six females, mean (range). Length of body: males 20.53 (19.40–21.65), females 20.63 (18.50–21.85); length of fore wing: males 27.94 (26.95–28.85), females 28.44 (27.30–29.65); width of fore wing: males 9.35 (8.70–10.10), females 9.59 (9.00–10.00); length of head: males 3.66 (3.45–3.85), females 3.71 (3.60–3.75); width of head including eyes: males 6.46 (6.20–6.65), females 6.52 (6.35–6.70); width of pronotum including suprahumeral plates: males 8.50 (8.35–8.70), females 8.44 (8.00–8.80); width of mesonotum: males 7.28 (7.00–7.65), females 7.29 (7.10–7.50).
Diagnosis. Carineta maracayensis sp. nov. can be distinguished from the other species of Carineta by having in combination the lack of thoracic markings, linear infuscation in the fore wing apical cells, long, radiating piceous pile and basal pygofer lobe appendage terminating in a single point. The lack of thoracic markings and the lack of infuscation on the fore wing crossveins, along the ambient vein of the wings or at the base of the wings, and the unique shape of the basal pygofer lobe extension.
The most similar species to C. maracayensis sp. nov. is C. tingomariaensis. The new species can be distinguished from C. tingomariaensis by the sinusoidal posterior opercular margin with the finger-like extension a straight continuation of the posterior opercular margin, the eight timbal ribs, and the basal pygofer lobe appendage with lateral curving termini, forming a single sharp point in C. maracayensis sp. nov. rather than the curved posterior opercular margin with the finger-like extension angled posteromedially from the posterior opercular margin, the six timbal ribs, and the bifurcating termini of the basal pygofer lobe extensions in C. tingomariaensis.
The unmarked Venezuelan species of Carineta include C. gemella Boulard, 1986, C. lichiana Boulard, 1986, C. socia Uhler, 1875 and C. ventrilloni Boulard, 1986. The new species can be distinguished quickly from C. gemella and C. lichiana by the contrasting abdominal coloration in those species and the basal pygofer lobe extensions that bifurcate or weave around one another respectively. The new species can be distinguished from C. socia by the larger body size and lack of bronzing in the distal fore wings of that species. The straight posterior operculum margin and the bifurcating terminus of the basal pygofer lobe appendage quickly distinguish Carineta ventrilloni from this new species.
Of the remaining potentially similar species, C. maracayensis sp. nov. can be distinguished from C. acommosis, C. modesta, and C. spoliata by the narrower posterior prothorax and the parallel sides of the abdomen in these species. In addition, the frons is at an approximate right angle to the vertex in C. acommosis and C. modesta. Carineta maracayensis sp. nov. can be distinguished from C. apicalis and C. naponore by the abdomen tapering toward the posterior in these species and the basal lobe appendages are large flattened lobes in C. apicalis, similar but smaller lobes in C. naponore and is elongated and pointed in C. maracayensis sp. nov.
Distribution. The species is known only from the type locality near Maracay in the coastal range of the state of Aragua, Venezuela.
