Introduction
The subfamily Pyrginae are characterised by their habit of basking with wings outspread, compared to the half-open position favoured by the Hesperiinae.
The tribe Eudamini includes 44 genera in the Americas, amongst which are the Long-tailed Skippers Urbanus, Chioides and Aguna; and other familiar genera including Phocides, Autochton, Astraptes and Calaenorrhinus.
The genus Autochton, previously known as Cecropterus, comprises of 13 smallish species which are characterised by having chocolate brown wings that bear a single white or creamy median band, and either 2 or 3 tiny apical spots. Most species also have a whitish margin to the hindwings. They can be distinguished by differences in the shape of the median band, the configuration and number of apical spots, and the pattern on the underside hindwings.
Autochton zarex is a common and widespread species found from Mexico to Argentina.
