Ochluma Grishin, new subgenus http://zoobank.org/ 014C323C-B441-41A0-A97F-EA3D552549D7 / Type species. Hesperia yuma W. H. Edwards, 1873. Definition. In the genomic phylogeny of Ochlodes Scudder, 1872, the second prominent clade consists of several North American species and represents a new subgenus (Fig. 131). This new subgenus differs from its relatives by a combination of the following characters: the two parts of the stigma are at least slightly offset from each other; ventral hindwing and the apex of ventral forewing are yellow to brown, sometimes with olive overscaling but not bright-green; valva is broader and lacks a prominent cleft between the harpe and ampulla, the aedeagus is medium in width or narrow, with a shorter and more robust style, terminal spike, and several larger cornuti, uncus and gnathos arms are approximately the same in length, extended and thinner than in most relatives, the juxta is broad and rounded, leaf-like, as wide as the distance between the ends of the process and the spike of the aedeagus. In DNA, a combination of the following characters is diagnostic in the nuclear genome: aly214.15.5:C75 T, aly1249. 14.7:G840A, aly119.1.1:A444G, aly 1916.7.3:G132A, aly 2874.9.7:G78A; and in COI barcode: T10 C or T142 C, T232 A, T292 T, A415 T, T478 C, T499 C or/and T553 C. Etymology. The name is a fusion of the names of the genus and the type species of the subgenus: Ochl [odes] + [y] uma. The name is a feminine noun in the nominative singular. Species included. The type species (i.e., Hesperia yuma W. H. Edwards, 1873), Hesperia sylvanoides Boisduval, 1852, Hesperia napa W. H. Edwards, 1865, and Ochlodes sylvanoides santacruza J. Scott, 1981, including their subspecies and synonyms. Parent taxon. Genus Ochlodes Scudder, 1872.
