Description

A revised key for Asian species of Sepedon is presented Taxonomic problems discussed include: 1) suitability of the shape of the internal genitalia (hypandrium and aedeagus) as a diagnostic character, 2) colour variability boundaries in Sepedon, and 3) general approaches to species delimitation. Following new synonymies are proposed: Sepedon neanias Hendel, 1913 = S. noteoi Steyskal, 1980, Syn. nov. and Sepedon tenuicornis Cresson, 1920 = S. gracilicornis Orth, 1986, Syn. nov. The taxonomic status of Sepedon aenescens Wiedemann, 1830 is discussed and the species is downgraded to subspecies rank as Sepedon sphegea aenescens Wiedemann, 1830. A new hypothesis on the taxonomy of Nearctic Sepedon that contradicts the generally accepted point of view has been proposed.
