MEASUREMENTS (MM). N = nine males or 10 females, mean (range). Length of body: male 21.18 (20.0–21.75), female 19.81 (18.0–21.0); length of fore wing: male 27.09 (26.15–28.1), female 27.03 (25.3–28.6); width of fore wing: male 9.03 (8.6–9.8), female 8.71 (8.2–9.0); length of head: male 3.71 (3.6–3.85), female 3.82 (3.7–3.95); width of head including eyes: male 8.24 (7.8–8.5), female 8.15 (7.45–8.65); width of pronotum including suprahumeral plates: male 7.65 (7.35–8.0), female 7.57 (6.85–7.95); width of mesonotum: male 6.50 (6.2–6.7), female 6.48 (5.75–6.9).

DIAGNOSIS. Selymbria ahyetios , S. pandora and S. subolivacea can be distinguished from this species by the lack of infuscation on the apex of their fore wing. The infuscation of the fore wing is found on the apex of the fore wing and on basal apical cells 1–3 and/or on the radiomedial cross vein in S. boliviaensis n. sp., S. danieleae , S. ecuadorensis n. sp., S. iguazuensis n. sp., S. loretoensis n. sp., S. madredediosensis n. sp., S. puntarenasensis n. sp. and S. stigmatica . Selymbria ahyetios can be distinguished by the diamond shaped widening of the postclypeus central sulcus near the postclypeus ventral apex, female operculum extending to sternite II with a posteromedial notch, an uncus with a curved posterior margin that is wider than the anal styles with recurved spines on either side, the wide notch in the posterior of male sternite VIII, and aedeagus with two short spines medially with larger extensions forming lateral wings. Selymbria chevauxensis can be distinguished by the fore femur primary spine is adpressed to the femur rather than being angled above it, the curved cubitus anterior 1 of the fore wing between the split with cubitus anterior 2 and the mediocubital crossvein. The fore wing length greater than 25 mm, uncus with curved lateral margins, and fore femur apical spine about half the length of the secondary spine distinguishes this species from S. guatemalensis n. sp. and S. pluvialis . The castaneous rather than piceous abdomen, the straight lateral uncus margins rather than reducing near the tip, and the angled medioposterior of the female sternite VII rather than smoothly curving to the posterior margin distinguishes S. guianensis n. sp.

The Panamanian species can be distinguished by the fore wing length being greater than 25 mm, an uncus with curved lateral margins, and a fore femoral apical spine about half the length of the secondary spine in S. cinctifera n. sp., the diamond shaped widening of the postclypeus central sulcus near the postclypeus ventral apex, an uncus with a curved posterior margin that is wider than the anal styles with recurved spines on either side, the wide notch in the posterior of male sternite VIII, and the parallel medial margins of the notch in female sternite VII in S. ahyetios , and the fore wing length being less than 25 mm, an uncus with straight lateral margins, and a small fore femoral apical spine, the expanding central sulcus to the posteroventral postclypeus, the constricted and rectangular uncus terminus, male sternite VIII without a terminal notch, and the posteriorly widening notch in female sternite VII in S. pluvialis .

DISTRIBUTION. The species is known only from the type series collected in Panama and Costa Rica. The range extends from southernmost Province of Panama to one of the northern border provinces of Costa Rica. The distribution may be extended to both the north and south with additional collecting efforts.
