Distribution and phenology. We have examined specimens of B. benito only from the western Mexican states of Jalisco, Colima, Guerrero, and Oaxaca, from cloud forest habitats in the Sierra Madre del Sur. De la Maza and de la Maza (1993) also reported the species from Chiapas, but we have not seen material from that state. In Oaxaca (Sierra Madre del Sur), B. benito flies most months of the year. Overall, records are concentrated from May to July and from September to November.

Biological notes. Buzyges benito is typically encountered as solitary males guarding perches (from 1.5 to 3 m above the ground) along roadsides, from 9:45 to 14:30 h, during sunny periods. Perching males are quite wary, and chase all other hesperiids from perching sites. Several grasses, including scattered Chusquea (Poaceae) , occur at habitats in Oaxaca, but the foodplants utilized by B. benito in these areas remain unknown. Despite repeated visits by the junior author and researchers from the MZFC to a known population of B. benito between La Soledad and Buenavista in the Sierra Madre del Sur of Oaxaca, a site where males can almost always be encountered under favorable weather conditions, the female of the species remains unknown.

Discussion. Poanes benito , described from and apparently endemic to Mexico, was compared only with Poanes zabulon in its original description ( Freeman 1979). The species is actually more similar in pattern and genitalia to B. rolla . The dorsum of B. benito has narrower black margins than B. rolla , the orange area of the forewing is not crossed by darkened veins, and there is less black in the apical region of the forewing so that the orange of the discal area is continuous with the subapical macules. The venters of the two species are virtually identical. The genitalia of B. benito , while resembling those of B. rolla , differ in detail (compare Fig. 68 and 69 View Figure 67-70 ). The species has been included within Poanes since its description (e.g., Mielke 2005b) despite Burns’ (1992a) contention that it belonged elsewhere. As noted for Buzyges rolla above, the genitalia of male P. benito (illustrated previously by Freeman 1979) indicate its placement in Buzyges and Buzyges benito is here proposed as a new combination.
