cording to our experience, the ventral pattern of the sexes of the same species are fundamentally identical). Concerning A. dahnersi there still remains much to be discovered. The female and the early stages are unknown, as well as the larval hostplant (supposed to be Loranthaceae, see Brown 1993: 53). Also, there is no distributional data aside from the localities of the types. Moreover, the entire genus needs a taxonomic revision, since the discovery of A. dahnersi and its still undescribed relative from Ecuador (Figs 3-4) and the recent placement of Thecla havila in Atlides (Bálint 2002: 129) underlined that the genus does exhibit supralimital characters, especially in cases linked to apparent long term allopatry in unusual ecological conditions. For example, in the restricted forest remnants of southeast Brazil occurs the outstanding sister species pair cosa-misma typified by supralimital phenotypes (d'Abrera 1995: 1122-1123). Acknowledgements - We express our sincere thanks to Mr Hans Dahners (Cali, Colombia) for calling our attention to the existence of this magnificent butterfly. We are pleased to name the species after him. He shared with us his own field notes concerning the behaviour of the species and allowed us to use these observations freely in the present contribution. We acknowledge here Mr Phillip Ackery (BMNH) and Prof Janusz Wojtusiak, Jagiellonian University (Krakow, Poland) for access to material under their curation. REFERENCES Ballmer, G. R. & Pratt, G. F.
