The species was still undescribed when the photo was taken. Mesosoma ( Figs 1 , 2D , 3 ). Covered by distinct whitish pilosity, the hairs shortest on mesoscutum; glabrous on speculum and widely around it. Pronotum on narrow anterior area, including almost until ventral angle, transversely finely striate; laterally with weak, parallel, longitudinal wrinkles, ventral angle posteriorly with two short, stout carinae ( Fig. 2D ); epomia quite short but distinct ( Fig. 2D ). Mesoscutum subcircular, 1.0× as long as wide, densely covered with closely spaced punctures, posteriorly distinctly longitudinally rugose ( Fig. 3B ); notaulus reaching 0.4× length of mesoscutum, notauli posteriorly convergent but widely separated. Scutellum sparsely punctate; scuto-scutellar carina disappears as soon as it reaches scutellum, axillary trough of mesonotum shallow, indistinct on scutellum. Subalar ridge wide, somewhat ovoid, not keeled. Epicnemial carina ending slightly above level of pronotal spiracle, far from subalar ridge ( Fig. 2D ). Mesopleuron dorsally rugulose to striate, speculum and wide area around it smooth, otherwise punctate/pilose; sternaulus moderately impressed, surface over sternaulus distinctly wrinkled ( Fig. 2D ). Postpectal carina ventrally entirely absent. Metapleuron dorsally densely punctate, sparser anteriorly, ventrally mostly smooth, posteriorly half centrally with transverse rugulosities ( Fig. 3D ). Propodeum ( Figs 3A, C–D ) in dorsal view short, 0.8× as long as wide. SWL 2.10; line of meeting with metapleuron wide, shallow, transversely strigate; pleural carina indistinct ( Fig. 3D ). Anterior transverse carina briefly but clearly interrupted centrally ( Fig. 3C ). Anterior area of propodeum from centrally smooth to laterally punctate rugulose in front of spiracle; posterior area densely transversely striate rugulose, from coarse anteriorly to weak posteriorly ( Figs 3C–D . Wings ( Figs 1 , 2F ). Fore wing vein 1M+Rs dorsal 0.7 straight, ventral 0.3 uniformly arched; crossvein 1cu-a arising basad of vein 1M+Cu by about 0.3 of its length; vein 2Cua 1.3× as long as crossvein 2cu-a; areolet quite large, APH 2.55, about as long as wide, AWH 0.95; 2r-m and 3r-m convergent; 3r-m anterior 0.65 spectral; 2-M slightly longer than 3-M; 4-Rs gently convex until slightly curved anteriorly on apical 0.2; HW1C 1.45. Metasoma ( Figs 1 , 3A ). T1 polished, shiny; anteriorly to spiracle narrowed, then trapezoidal, wide, T1LW 1.8; T1WW (not visible); dorsolateral carina absent; ventrolateral carina absent; spiracle moderately prominent. T2 short, trapezoidal, T2LW 0.70, T2WW 1.53. T2–3 mostly polished ( Fig. 3A ). T7–8 much longer than T5–6 ( Fig. 1 ). Ovipositor long ( Fig. 1 ), OST 1.65; ventral valve with eight teeth, the apical two very weak ( Fig. 2E ). Color ( Figs 1–3 ). Brown (from 170,90,55 to 95,50,40), with dark brown metasoma and yellowish orbital band. Head ferruginous (195,115,96), orbital band yellowish (250,240,190), widest ventrally, interrupted at malar space and dorsally by dark brown (40,40,40) area. Mandible dorsal and ventral margins and apical 0.3 dark brown, central 0.3 reddish, basal 0.4 yellowish. Clypeus orange brown, its apical margin brown ( Figs 2A–B ). Supraclypeal area centrally dark brown, except for a dorso-central reddish spot ( Fig. 2A ); supra-antennal area centrally reddish ( Fig. 2D ). Antenna dark brown, scape ferruginous. Mesosoma , including all legs, brown, anteriorly lighter, posteriorly darker. Fore wing fuscous, with two wide dark bands, one centrally and one apically ( Fig. 1 ); hind wing lightly and entirely infuscate, apex darker. Metasoma mostly dark brown, except petiole and ventral part of T8 ferruginous ( Fig. 1 ). Ovipositor reddish brown, its sheaths dark brown. Variation . Unknown. Male . Unknown. Santos (2016) reported a male specimen from the Dominican Republic ( Pedernales Prov. , 21 km N. Cabo Rojo, 19-20-VI-76, R.E. Woodruff, at FSCA) as species inquirenda , but that specimen has a strongly different color pattern (see Santos, 2016:14 ), as well as important structural differences, ruling out the possibility of conspecificity with the present species. These differences include mesosoma mostly black or blackish ( vs . brown in N. bajari sp. nov. ), with a rich pattern of whitish marks ( vs . uniformly brown); fore wing with a single apical infuscate mark ( vs . central and apical marks); propodeum entirely black ( vs . brown); central ocellus about as large as the lateral ones ( vs . distinctly larger); and areolet distinctly longer than wide, AWH 0.8 ( vs . about as long as wide, AWH 0.95). FIGURE 5 . Distributions for species of Nesolinoceras Ashmead. Circles , N. ornatipennis (Cresson) . Triangles , N. laluzbrillante Santos. Diamond , N. bajari sp. nov. Star , Species Inquirenda. Comments . The new species is quite different from both previously known species, from which it can be immediately separated by having a body mostly unicolorous ( vs . mesosoma with several large whitish spots in both N. ornatipennis and N. laluzbrillante ), and by having the longest ovipositor (OST 1.65 vs . 1.00–1.20). Several other features, listed in the taxonomic key, also separate N. bajari sp . nov . from the two other known Nesolinoceras . Etymology . The specific epithet is a noun in apposition. The term bajari is from the Taíno language, originally spoken in the Dominican Republic, and means “[a] title of distinction and high respect” (https://www.taino-tribe. org/tedict.html). It is both a reference to the collecting site –the highest and most central in the country– and a reverence to the temporal endurance of both the Taíno and the new species. Biology . Unknown. Distribution ( Fig. 5 ). Nearly all confirmed records for N. ornatipennis and all known specimens of N. laluzbrillante are from areas near to the coast ( Fig. 5 ), usually at sea level ( Fig. 6 ), where temperatures are farily constant, varying no more than 5°C throughout the year, with heat stress highest during the wet season, due to humid heat by rain and cloudiness, but lower during the breezy, cooler dry season (https://rcc.cimh.edu.bb/caribbean-climatology/). The type of environment from where N. bajari sp . nov . is known, however, is much different. The José Armando Bermúdez National Park spans through the northern slopes and central portions of the Central Mountain Range in the Dominican Republic, an area of remarkably high altitudes, with several peaks over 3,000 m , and with cold and cool temperatures (−9 to 15°C) during most of the year. The range supports the Hispaniolan pine forests ecoregion, of the Tropical and subtropical coniferous forests Biome.
