Diagnosis. Similar to J. euthenia, although differentiated from the latter based on the primarily brown to light brown mandible, flatter clypeus and supraclypeal area in lateral view, and subquadrate head.
Description. Female (Fig. 3A–H). Body length: 6.9 mm; fore wing length: 4.0 mm.
Color. Primarily black with a few yellow and yellowish-white markings and partially brownish legs. Head black, except for mandibular brown to light brown with black base and dark brown apex, paraocular area with narrow light yellowish mark medially dorsal to antennal base and at dorsolateral corner (25% of specimens with venterolateral corner brownish). Antenna black, except for pedicel apically brownish. Mesosoma black, except dorsal margin of pronotum and tegula yellowish-white. Fore leg: coxa varying from entirely dark brown to black, 50% of specimens with brownish mark anterolaterally; trochanter dark brown to black with brownish apex; trochantellus brown; femur anteriorly brownish-yellow, except for basal 0.3 dark brown, posteriorly dark brown, except for apical 0.2 brownish-yellow; tibia brownish-yellow ventrally becoming brownish dorsally; tarsus dark reddish-brown, except for tarsomere 5 dark brown. Mid leg: coxa varying from black to dark brown; trochanter dark brown to black with brownish apex; trochantellus brown; femur dark brown except for anteriorly with apical 0.2 brownish-yellow, posteriorly varying from entirely dark brown to apical 0.1 brownish-yellow; tibia brownish-yellow ventrally becoming brownish dorsally; tarsus dark reddish-brown, except for tarsomere 5 dark brown. Hind leg: coxa and trochanter black; trochanter black; trochantellus brown; femur dark brown to black except for apical 0.1 brownish; tibia brownish-yellow ventrally; tibia brown to reddish-brown; tarsus varying from reddish-brown to dark reddish-brown, 50% of specimens with tarsomeres 1–3 paler basally. MS1 black. T2–7 black with lateral and posterior margins brownish, 50% of specimens with anterior margins of T4–6 with brownish semi-circular marks. Wing: membrane clear; basal 0.1 of wing with veins white, remaining sections brown.
Head. Subquadrate. Mandible slightly narrowed (MI: ~3.5×). Clypeus and supraclypeal area nearly flat in lateral view. Clypeus smooth and coarsely, sparsely punctate with punctures denser along margins. Supraclypeal area smooth and moderately punctate with 0.2–0.8× their diameter. Gena smooth and finely punctate with punctures separated by 1.0–3.0× their diameter, denser posteriorly. Supra-antennal are smooth and moderately punctate with punctures separated by 0.5–1.5× their diameter. Vertex smooth and finely, sparsely punctate with punctures separated by 1.0–3.0× their diameter, denser medially. Hypostomal and occipital carinae meeting before mandible. Antenna with 27 flagellomeres.
Mesosoma. Of normal width, not laterally flattened. Dorsal 0.6 of pronotum smooth and finely, sparely punctate with punctures denser at margins, anterior 0.4 rugulose. Propleuron smooth and finely, sparsely punctate with punctures separated by 2.0–4.0× their diameter. Mesonotum smooth, very finely, sparsely punctate anteromedially, remainder moderately punctate with punctures separated by 0.2–1.0× their diameter, sparser laterally. Scutellum smooth and moderately punctate with punctures separated by 1.0–1.5× their diameter. Mesopleuron smooth, dorsal 0.3 moderately punctate with anterodorsal corner rugulose, ventral 0.7 with punctation coarser and denser with some punctures forming rugulae. Speculum smooth and finely punctate. Ventral division of metapleuron smooth and coarsely, densely punctate with punctures sparser anteriorly and posteriorly at margin denser with some punctures confluent forming rugulae. Propodeum: of normal width, nearly equal in length and width; evenly rounded mediolaterally; dorsal face smooth and densely coarsely punctate laterally with punctures adjacent to subadjacent becoming sparser medially, posterior face rugulose; carinae obsolete except for pleural carina, posterior transverse carina, and median longitudinal carina posterior to posterior transverse carina subobsolete. Legs of normal length. Hind femur normal, not anteroposteriorly flattened.
Metasoma. MS1 smooth and postpetiole moderately punctate with punctate denser anteriorly and laterally and sparser medially and posteriorly. T2 smooth and varying from finely to moderately punctate becoming sparser and finer near posterior margin. Gastrocoelus well-developed. Thyridium well-developed; narrow, 0.6× as wide as interthyridial width; distant from T2 anterior margin by 0.2× tergite length. T3–7 smooth and varying from moderately to finely punctate with punctation becoming sparser and finer posteriorly.
Male (Fig. 4A–C). Body length: 6.6–7.0 mm; fore wing length: 4.3–4.4 mm.As in female except for: metasoma more densely punctate with punctures separated by 0.5–1.0× their diameter. Antenna with 26–27 flagellomeres.

Distribution. All but one specimen was collected at the type locality in the Sierra Nevada de Santa Marta National Natural Park (PNN Santa Marta) (Fig. 12). The only specimen not from this locality was apparently collected in the Iguaque Flora and Fauna Sanctuary (SFF Iguaque) which was extensively sampled by Malaise trapping for several years. Due to the geographic isolation of the Sierra Nevada de Santa Marta mountain range and the high levels of endemicity in the native fauna (Todd & Carriker 1922; Hernández-Camacho et al. 1992), the record from SFF Iguaque is suspect and has been excluded from the distribution map. It may be the result of mislabeling during mounting or mishandling the Malaise trap samples. Alternatively, the specimen may have indeed been collected in SFF Iguaque which further sampling of the region could corroborate.
Etymology. The species name refers to the type locality and honors the indigenous Kogi community that live within the Sierra Nevada de Santa Marta National Natural Park. Specifically Gonawindua is the place name used for Pico Cristóbal Colón and a general term for the surrounding region by the Kogi people.
