Brassolis isthmia isthmia Bates, 1864

( Plate 2 , figs. 1–4; Plate 3 , figs 4–6)

The description of isthmia was based on two males from Lion Hill, Panamá. In the BMNH Type Collection, there are two males; the one with the additional label ‘figured specimen’ is designated lectotype ( Plate 2 , figs. 3&4). Male nominate isthmia in Panamá have a distinct orange streak alongside Cu 2 on the hindwing. The range of the nominate taxon is generally regarded as extending from Nicaragua to the Cauca Valley in Colombia ( Stichel 1909; 1932). Nominate isthmia , if it does occur in Colombia, is probably confined to the northwest, but I have seen no undoubted specimen from Colombia; there is, however, one male in the MNHN from ‘Cauca’.
