Here is the short summary that we present on the first paragraph:
A case of homonymy between Pampa Walker, 1854 (a genus of zygaenid moths) and Pampa Reichenbach, 1854 (a genus of hummingbirds) has been the subject of multiple attempts at resolution during the 19th and 20th centuries. Although previously resolved, the homonymy resurfaced when phylogenetic analysis of Campylopterus Swainson, 1827 revealed it to be paraphyletic, leading to its reclassification and the resurrection of several genera, including Pampa Reichenbach, 1854 (Stiles et al. 2017). This probably happened in part because most of the literature regarding the
history of Pampa Walker, 1854 is not readily accessible either online or in printed form for researchers outside the field of Zygaenidae taxonomy. To address this issue, we present the bibliographical evidence regarding both genera and revalidate Platystylopterus Reichenbach, 1854 rev. stat. as the valid genus for the hummingbirds.
