Diagnosis. Spot on the stigma of males with a brown stripe highlighting a hyaline vein-less region, spot on the stigma of females oval, small, with two different shades of brown, one lighter and distal, the other almost black and proximal.

Redescription. Male —Serrate antennae. Prothorax slender, lateral margins slightly crenulated on the prozona, smooth on the metazona. Metazona with a weakly marked central keel (Fig. 34 E). Forecoxae with 8–12 large spines, which alternate with 2–8 smaller spines (Fig. 36 E). Forefemora slender, the third discoidal spine only dark on their anterior surface; 15–17 anteroventral spines, usually 15, the first spine and all the big spines dark on their anterior surface, the 8th, 10th, 12th and 15th spines may present a small spot of the same coloration on their insertion. Anterior femoral spot extending from femoral groove to the 6th anteroventral spine, rectangular, an effaced black color (Fig. 38 E). Foretibiae with 10–12 posteroventral spines, usually 11, and 14–16 anteroventral spines, usually 15; tibial spur and the spine before it black on their anterior surface; the tibiae have a dark spot on the middle of their anterior surface (Fig. 40 E). Foretarsi with apical black spots on the anterior surface of the tarsomeres I to IV, and a basal spot on the anterior surface of tarsomere I. Discoidal area of the forewings with a narrow opaque-green stripe anteriorly after the stigma, hyaline before it. Spot on the stigma small, with a hyaline region without crossveins and a posterior brown spot. Hindwings hyaline (Fig. 55 A).

Genitalia. Left phallomere longer than wide; sclerite L4B as long as wide; paa elongated, slightly dilated on the left side of its base, angled approximately 45° from the body axis, apex simple, directed ventrally (Fig. 42 E); pda short, narrow, flattened, sharply bent to the right and anteriorly, apex strongly sclerotized and tapered (Fig. 45 E); afa elongated, parallel to the body axis (Fig. 43 E), right margin smooth and lightly sinuous (Fig. 44 E), posterior apex tumid with two small projections directed posteriorly, rugged and sclerotized, anterior apex straight, margins sclerotized, tumid, without forming a groove (Fig. 43 E); loa short, bent to the right (Fig. 43 E); membrane adjacent to afa glabrous (Fig. 43 E). Right phallomere with the posterior apex rounded; bm short, with a wide expansion (Fig. 46 E); pia short, strongly sclerotized (Fig. 47 E–48E); pva short, sclerotized, angular apex (Fig. 48 E); an elongated, apex smoothly rounded (Fig. 47 E).

Female —Prothorax slender, lateral margins slightly crenulated. Metazona with a weakly marked central keel (Fig. 35 D). Forecoxae with 7–10 large spines, which alternate with 5–10 smaller spines (Fig. 37 D). Forefemora slender, the third discoidal spine dark on their anterior surface; 15–16 anteroventral spines, usually 15, the first spine and all the big spines dark on their anterior surface, the 8th, 10th, 12th and 15th spines may present a small spot of the same coloration on their insertion. Anterior femoral spot extending from the femoral groove to the 6th spine, rectangular, an effaced black color (Fig. 39 D). Foretibiae with 10–12 posteroventral spines and 15–17 anteroventral spines; tibial spur and the spine before it black on their anterior surface; the tibiae have a dark spot on the middle of their anterior surface (Fig. 41 D). Foretarsi with apical black spots on the anterior surface of the tarsomeres I to IV, and a basal spot on the anterior surface of tarsomere I. Spot on the stigma oval, small sized, with an anterior white spot, a proximal dark brown, nearly black, spot, and a posterior and distal light brown spot (Fig. 55 B). Costal area of the hindwings hyaline, discoidal and anal areas hyaline with yellow stripes on the crossveins.

Genitalia. Base of the gonapophysis VIII projecting inwards (Fig. 49 D); bv roughly triangular, anterior apex dilated (Fig. 49 D), internal surface sculpted (Fig. 50 D); ib sclerotized, sculpted (Fig. 50 D); pe elongated, weakly sclerotized, with irregular margins (Fig. 50 D); gs weakly sclerotized, smooth (Fig. 51 D); ls roughly rectangular, posterior process elongated, conical (Fig. 51 D).

Ratios. Head/prothoracic-width: 1.22–1.35; metazona/prozona: 3.79–4.3; metazona length/prothoracic width: 3.3–3.79; metazona/forecoxae: 1.35–1.5; forefemora length/width: 4.52–4.93.

Remarks. Stagmatoptera septentrionalis was described by Saussure & Zehntner (1894) based on one specimen from Panama. This species is similar to Stagmatoptera supplicaria, but differs from the latter for lacking crossveins in the spot on the male stigma, and the stigma spot of females is much smaller. This species represents the northernmost distribution in the genus, reaching as far north as Martinique, in the Caribbean area.

Distribution. Colombia, Costa Rica, French Guiana, Trinidad & Tobago, Venezuela.
