Female. Unknown, supposedly similar to male but larger with wider wingshape and an additional tail at vein terminus CuAl, dorsal colouration bluish and fore wing without androconia. Distribution - Geographic: known only from a single Colombian locality at elevation 1900-2200 m. Temporal: specimens were recorded throughout the year. Etymology - Named after the collector of the type material Mr Hans W. Dahners, Cali, Colombia. DISCUSSION Type locality - The Colombian locality is located in the Cerro de San Antonio o La Horqueta, immediately to the west of Cali. The area is accessible via a secondary road, which branches off from the National road Cali-Buenaventura at kilometer 14. The ridge conserves about 600 ha of forest. The geographic coordinates of the forest are 76°38' W and 3°30' N and extend between 1800 and 2200 m above sea level in its uppermost part. The area is protected, part of the Forestal Reserve Zone of the Cali River Basin. According to the system of Holdrige (1967) the San Antonio Forest is classified as Very Humid Low Mountain Forest with the following climatic limits: mean annual biotemperature between 12-1

8°C and mean annual rainfall between 2000 and 4000 mm (Espinal 1986). Rainfalls peak twice: during April-May and October-November. Typically, in the afternoon, the forest is covered by fog and low clouds, which form through the cooling of watercharged air coming in from the Pacific Ocean. Within the system of Grubb et al. ( 1963) the forest is classified as Low Mountain Rain Forest. The vegetation of the Cerro San Antonio is characterized by the presence of a great number of palm trees of the genera Geonoma and Euterpe and Rubiaceae such as Palicourea, which are the forest's principal component (28% and 21%, respectively). The other species (2%) are over 10 m tall trees and medium tall bushes (2-4 m): Ficus (Moraceae), Cecropia (Cecropiaceae), Nectandra (Lauraceae), Ocotea (Lauraceae), Hieronyma (Euphorbiaceae), Alchornea (Euphorbiaceae), Miconia (Melastomataceae), Inga (Mimosaceae), Oreopanax (Araliaceae), Piper (Piperaceae), Prunus (Rosaceae), Andira (Fabaceae), Tibouchina (Melastomataceae) among others. Most of the trees have their trunks covered profusely with lichens, bromeliads, and vines of a variety of species (Kattan et al. 1984). Thus far, all A. dahnersi specimens have been collected while hilltopping at the Cerro San Antonio within the Farallones section of the Western Cordillera, which separates the Cauca River valley from the Pacific coastal plain.
