Cruciform elevation ground color with piceous mark posterior to anterior arm of cruciform elevation, wing groove green with piceous spot on anteromedial and anterolateral margins. Metanotum castaneous with ground color dorsum and posterior margin, dense pile radiating from posterior margin. Short golden pile on disk between anterior arms of cruciform elevation and on lateral cruciform elevation, long silvery pile in posterior wing groove and on posterior margin. Ventral thoracic segments ground color, covered with white pubescence.

Cubitus anterior 1 of the fore wing straight between the split with cubitus anterior 2 and the mediocubital crossvein.

Basal cell longer than broad, hyaline with slight greenish tint. Pterostigma present, mottled with red. Infuscation on distal subcostal vein, radius anterior 1, radius anterior 2 and distal radius posterior, infuscation extending onto ambient vein from subcostal vein to posterior of radius posterior vein extending to wing apex, second infuscation expanding from middle of subcostal vein across pterostigma, proximal apical cells 1–2, distal half of ulnar cell 1, and anterodistal ulnar cell 2 including entire radial and most of radiomedial crossveins. Basal membrane of fore wing gray with dark gray posterior margin. Venation of hind wing similarly colored with anal veins 2 and 3 castaneous, anal vein 3 piceous around base. Anal cell 3 and anal cell 2 along anal vein 3 gray, anal cell 2 along anal vein 2 gray, gray area margined with infuscation in anal cells 2 and 3, spot of infuscation on wing margin distal to apical cells 1 and 2.

Legs. Coxae, trochanters, femora and proximal tibiae ground color, distal tibiae and tarsi castaneous, medial mesotarsus lighter. Fore femora proximal spine forming acute angle to femur with narrower base than secondary spine, secondary spine broadly triangular, upright to femoral axis, about as long as primary spine, and small, angled apical spine, primary spine ground color at base, piceous in middle with castaneous tip, secondary spine with piceous base except distal ground color spot and castaneous tip, apical spine ground color, long silvery pile radiating from ridge between spines. Tarsal claws dark castaneous with piceous tips, tibial spurs and comb castaneous with darker tips. Legs covered with long and short silvery pile.

Operculum. Female operculum ground color, straight lateral angled slightly mediad, sinuate when viewed from the side, posterolateral angle obtuse, posterior margins curving anteriorly in medial half, terminating medially at medial meracanthus, reaching to middle of sternite II.

Abdomen. Tergites castaneous with piceous anterolateral region, percentage reducing in posterior tergites, piceous mark on lateral tergite 2 margin, tergites 4–7 with lighter posterior margins, tergite 8 with lighter dorsolateral regions, may be ground color in fresh specimens, auditory capsule castaneous with piceous anterior spot on margin, tergites covered with silvery pile, denser on lateral tergites. Female abdominal segment 9 light castaneous, dark castaneous dorsolaterally, piceous on stigma and ventrally lateral to margin covering of gonocoxites and continuing to posteroventral margin, covered with short silvery pile on dorsolateral surfaces, long golden pile on ventral and ventrolateral surfaces. Posterior margin of female abdominal segment 9 straight. Sternites castaneous with dark castaneous transverse fascia on posterior midline, covered with long and short silvery pile. Epipleurites castaneous covered with silvery pile. Female sternite VII with a deep medial notch, V-shaped anteriorly, angled laterally to about half sternite length where angle reduces and arches to posterior margin to semicircular posterior margin, lateral margin sinuate constricting posterior extension in middle of lateral margin, castaneous, lighter on distal posterior extension, covered with silvery pile, dense golden pile radiating from either side of notch center.

Gonocoxite X piceous not extending to length of anal styles which do not reach to terminus of dorsal beak, with radiating golden pile. Anal styles piceous with lighter ventral side, anal tube piceous.

Male is unknown.

MEASUREMENTS (MM). N = one female, mean. Length of body: 18.55; length of fore wing: 24.0; width of fore wing: 7.8; length of head: 3.15; width of head including eyes: 6.95; width of pronotum including suprahumeral plates: 6.3; width of mesonotum: 5.6.

DIAGNOSIS. Although it is not preferable to describe a species from a single female, the characteristics of this specimen preclude it from being classified as one of the other known species. 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 only on the apex of the fore wing in S. ahyetios , S. chevauxensis n. sp., S. cinctifera n. sp., S. guatemalensis n. sp., S. guianensis n. sp., and S. pluvialis . The fore wing infuscation is found on the radiomedial crossvein and not on basal apical cells 1–3 in S. danieleae . This new species can be distinguished from the females of S. boliviaensis n. sp., S. ecuadorensis n. sp., S. iguazuensis n. sp., S. loretoensis n. sp., S. madredediosensis n. sp., and S. stigmatica by the medial margin of the notch in the posterior extension of sternite VII curving laterad while it is straight or curving mediad in these species. The piceous region on the dorsal head is not reduced between lateral ocelli and eye in S. boliviaensis n. sp., S. ecuadorensis n. sp., S. iguazuensis n. sp., S. loretoensis n. sp., S. madredediosensis n. sp., and S. stigmatica but is reduced in S. puntarenasensis n. sp. It is also the only species with two apical spots of infuscation in each fore wing known from Central America.

DISTRIBUTION. The species is known only from the holotype collected in Puntarenas Province, Costa Rica.
