Fig. 1a

Euxesta latifasciata Wulp, 1899:397 (description); Hendel, 1909:154 (key), 167 (comparison with E. obliquestriata and E. sororcula ), 1910:27 (catalog); Curran, 1935:10 (key); Steyskal, 1968:54. 18 (catalog).

Type Specimens. Syntypes 2 ♂, both labeled:“MEXICO, Cuernavaca in Morelos” and 1 ♀, labeled: “Tierra Colorada in Guerrero” (H. H. Smith) (NHMUK). Not examined .

Remarks. Wulp (1899:tab. XL, fig. 9) illustrated the wing and diagnosed the species in the key as having four bands on the wing, of which the discal and subapical ones are much widened towards the posterior margin and the apical crossband being wider than the hyaline space between the subapical and apical, as well as having the legs rufous.

The Data Portal of the NHMUK ( BMNH, 2021a) refers to a “lectotype and paralectotype,” but no formal lectotype designations have ever been published.

Distribution. Mexico.
