Resolving inconsistencies between Plötz’s descriptions and presumed type specimens of some Hesperiidae (Lepidoptera)

Abstract

Comparing specimens curated in MfN as primary types of Hesperiidae names proposed by Carl Plötz with the original descriptions and unpublished drawings reveals a number of inconsistencies that we address. Lectotypes are designated for Telegonus labriaris Butler, 1877, Eudamus jalapus Plötz, 1881, and Apaustus interpunctata Plötz, 1884. Neotypes are designated for Netrocoryne seneca Plötz, 1882 and Hesperia irma Plötz, 1882. Hesperia ulphila Plötz, 1883 is treated as a nomen dubium. As a result of these designations, the following are junior objective synonyms: Netrocoryne seneca Plötz, 1882 of Telegonus labriaris Butler, 1877 and Hesperia irma Plötz, 1882 of Pamphila irma Möschler, 1879, the latter two names being homonyms. In all these instances, the original descriptions are satisfied, and, except for A. interpunctata, the current application of these names is unaffected. Taxonomically, Callimormus diaeses Schaus, 1902, stat. rest. is a valid species, not a synonym of A. interpunctata, which is a junior subjective synonym of Eutocus vetulus (Mabille, 1883).
