Gyrocheilus
Gyrocheilus is a monotypic genus in the family Nymphalidae. The single contained species is Gyrocheilus patrobas, the Red-bordered Brown, which is found in central and southern Arizona and Mexico. The habitat consists of streamsides in open coniferous forests in the mountainous areas.
The wingspan is 51–60 mm. The wings are dark brown, with identical upper and lower sides. The forewing has a light brown submarginal band and three to four small white spots just inside the band. The hindwing has a wide, dull red border. There is one generation peryear with adults on wing from mid-August to October.
The larvae feed on Muhlenbergia emersleyi.
