We propose several nomenclatural changes for taxa in the lampyrid subfamilies Ototretinae, Pho­turinae, and Psilocladinae (Coleoptera: Lampyridae). Evidence for the correct year of description of Drilaster albicornis lateobscura (Pic, 1921) is presented. Spellings are corrected for Drilaster debilis holzi (Pic, 1914), Drilaster impustulata fukienensis (Pic, 1955), Drilaster moutoni (Pic, 1911), Drilaster pendleburyi (Pic, 1943) and Pyrogaster lunifera (Eschscholtz, 1822). We also explain the validity of the name Photuris flavicollis Fall, 1927. Fifty-eight taxa described as variations or aberrations in the subfamilies Ototretinae, Photurinae, and Psilocladinae by Delkeskamp (1977), McDermott (1966), Wittmer (1944), and Pic (1924c), are evaluated, with their availability determined based on ICZN (1999: Article 45.6).

We address taxonomic problems with species and genera in the currently valid lampyrid subfamilies Ototreti­nae, Photurinae, and Psilocladinae (Coleoptera: Lampyridae) in an effort to update McDermott’s (1966) World Lampyridae Catalog. Ballantyne and Keller (2021), Keller (2021, 2022), Keller and Ballantyne (2021, 2023), and Keller and Branham (2018a, b, c) have corrected several problems mostly in other subfamilies, but not in detail for the three subfamilies listed above. We are correcting Ototretinae, Photurinae, and Psilocladinae nomencla­tural details not only for the updated checklist (Keller in prep.), but also to address any mistakes present in online databases, regional checklists, and catalogs which mostly relied on Wittmer (1944) and McDermott (1966). We address the following groups of issues: three incorrect publication dates (two of which resulted in the species being nomina nuda), five misspelled names, one instance of validity of a taxon name, and 57 determinations of subspecific status within Ototretinae, Photurinae, and Psilocladinae. Additionally, we address the correct spell­ings of the genera Ceylanidrilus Pic, 1911 and Flabellototreta Pic, 1911. For each of these, we explain the issues and propose corrections.
