Type species: Pyrgus delagoae Trimen, 1898 (Fig. 2b).

Diagnosis. Keys to 15 in de Jong (1978: 30), constituting his delagoae species group. Morphologically differs from other species in the genus by the following characters. Forewing dorsal white spots at the base of CuA 2 -1A+2A cell (space 1B) absent, and the spot at the base of the discal cell is absent in most species (some white scales along cubital vein may be present forming a narrow streak). Ventral hindwing with a straight median white band, i.e., a white spot in cell RS-M 1 (space 6) joins the central spot (discal cell) to the outer (and not inner) spot in cell Sc+R 1 - RS (space 7). In male genitalia, coecum of aedeagus shortened or absent; valva with the costal process and harpe (=cucullus) lacks a fold covering the costal process, or the fold is small. In DNA COI barcode region, a combination of the following base pairs is diagnostic: T19A, T22A, T70A, T374G, and T646C.

Derivation of the name. The name is a feminine noun in the nominative singular derived from the name of the type species.

Species included: Encompasses delagoae species groups, as it was defined by de Jong (1978). Full species list is given below.

In addition to Ernsta, the phylogenetic trees (Fig. 1) suggest a second new genus, which while being monophyletic with Ernsta is prominently different from it.
