Selymbria ahyetios Ramos & Wolda, 1985 Selymbria sp. H2 Wolda 1977: 239 . Selymbria stigmatica non Germar Wolda 1984: 451 . TYPE LOCALITY . Barro Colorado Island , Panama . REMARKS. Type material is in the USNM , STRI , and the Ramos collection ( NCSU ) ( Ramos & Wolda 1985 ) . The species can be distinguished from all but S. pandora and S. subolivacea by the lack of infuscation on the apex of the fore wing. This species is slightly smaller (body length about 18.5–19.5 mm , wing span about 52.5–53.5 mm vs. 21–22 mm and 55-57 mm in S. pandora ), with the dorsal head marked with piceous rather than being mostly piceous, general body coloration ochraceous rather than tawny, abdominal tergites fuscous rather than testaceous, and basal area of the wings grayish and piceous rather than red. The Brazilian, S. subolivacea can be distinguished by its primarily greenish tawny coloration, green basal areas of the wings and larger body size (body length 27 mm , wing span 78 mm ). If the specimen has infuscation in the apex of the fore wing, this is the only species to have the infuscation restricted to distal to the ambient vein. Contrary to the description ( Ramos & Wolda 1985 ), the four paratypes studied had infuscation on the fore wing apex that extended across the ambient vein into the distal apical cells. It can be distinguished from S. chevauxensis n. sp. , S. cinctifera n. sp. , S. guatemalensis n. sp. , S. guianensis n. sp. , and S. pluvialis , the species with only apical fore wing infuscation, by the diamond shaped widening of the postclypeus central sulcus near the postclypeus ventral apex, sinuate apex of the secondary spine of the fore femur, the ovipositor sheath extending to the level of the dorsal beak, female operculum extending to sternite II with a posteromedial notch, female sternite VII posterior extension with parallel margins, 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, the aedeagus with two short spines medially with larger extensions forming lateral wings. 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 distinguish these species from examples of S. ahyetios with apical infuscation. 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 Panama ( Sanborn 2013 , 2018). Panamanian specimens were collected in lowland forest on Barro Colorado Island at 120 m altitude ( Ramos & Wolda 1985 ; Wolda 1977 ; 1988 ; 1989 ; 1993 ; Wolda & Ramos 1992 ).
