Type species. Zea martini Distant and Pryer, 1887 .

Definition. Previously placed in Acerbas de Nicéville, 1895 (type species Hesperia anthea Hewitson, 1868 ), this genus is not monophyletic with it and is sister to Zela de Nicéville, 1895 (type species Zela zeus de Nicéville, 1895 ) instead ( Fig. 10 ). Keys to J. 22.4 in Evans (1949). Diagnosed by the following combination of characters: mostly brown above wings with small forewing spots, milky areas by hindwing anal margin and broad central band on hindwing below; forewing vein CuA 2 originates in the middle between wing base and the origin of vein CuA 1; uncus broad, bilobed caudad, indistinctly separated from tegumen; tegumen with small side processes and a long central process; penis bulky and stout; valva twice as long as broad, with a prominent and rounded ampulla that is separated from a narrow but large harpe gradually upturned and rounded at the dorsal end protruding above ampulla. In DNA, a combination of the following base pairs is diagnostic: aly103.51.12:A1212T, aly 2618.5.1: T1489 A, aly420.23.4:A277C, aly276561.5.1:G1724G (not C), aly276561.5.1:A1721A (not G), aly 1624.1.10:G534G (not A).
