Comment

Composed of former Desmognathus 'quadramaculatus' lineages C, E, and G of Pyron, O'Connell, Lemmon, Lemmon, and Beamer, 2022, Ecol. Evol., 12 (2: e8574): 1–38, according to the original publication where comparative morphology, molecular markers, and distribution were detailed. 

Under the pre-2022 taxonomy, one widespread nominal species, Desmognathus quadramaculatus was known to be a complex of species. Complicating this was the fact that the names Salamandra quadramaculata Holbrook, 1840, as well as Salamandra nigra Green, 1818, are synonyms of Salamandra fusca Green, 1818 (Pyron and Beamer, 2020, Zootaxa, 4838: 226–228). This left a widespread complex of "Black-bellied Salamanders" largely without names (although excepting Desmognathus folkertsi, previously named). Subsequently Pyron and Beamer, 2022, Bionomina, 27: 1–43, remedied this situation with the naming/recognition of Desmognathus amphileucus (former Desmognathus 'quadramaculatus' A), Desmognathus gvnigeusgwotli (former Desmognathus 'quadramaculatus' F), Desmognathus mavrokoilius (former Desmognathus 'quadramaculatus' C, E, and G), and Desmognathus kanawha (former Desmognathus 'quadramaculatus' D). As a result, the literature of former Desmognathus 'quadramaculatus' is only to be used cautiously for any of the daughter species. 

The former comment under Desmognathus 'quadramaculatus' follows: See detailed accounts by Valentine, 1974, Cat. Am. Amph. Rept., 153: 1–4, and Petranka, 1998, Salamand. U.S. Canada: 206–213. Rissler and Taylor, 2003, Mol. Phylogenet. Evol., 27: 197–211, presented molecular evidence that suggests that this nominal species is a composite of cryptic species, forming a paraphyletic series with respect to Desmognathus marmoratusBeachy and Bruce, 2003, Amphibia-Reptilia, 24: 13-26, reported on a miniturized populations in the Bald Mountains of North Carolina, USA. Watson, Pauley, and Camp, 2005, in Lannoo (ed.), Amph. Declines: 723–726, provided an account containing a detailed summary of the literature and range. Jones, Voss, Ptacek, Weisrock, and Tonkyn, 2006, Mol. Phylogenet. Evol., 38: 280–287, and Wooten and Rissler, 2011, Acta Herpetol., Firenze, 6: 175–208, suggested that neither Desmognathus marmoratus nor Desmognathus quadramaculatus are monophyletic, instead being species complexes composed of multiple inter-related lineages. See comment under Desmognathus marmoratus for additional relevant literature. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 430, provided a brief account, photograph, and range map. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 106–107, provided an account of larval morphology. Beamer and Lamb, 2020, Zootaxa, 4734: 1–61, in their discussion of Desmognathus mtDNA phylogenetics, confirmed the intercalation of apparent cryptic species under this name with apparent cryptic species of Desmognatus marmoratausPyron, O'Connell, Lemmon, Lemmon, and Beamer, 2020, Mol. Phylogenet. Evol., 146 (106751): 1–13, suggested on molecular grounds that this nominal species is a complex. Pyron, O'Connell, Lemmon, Lemmon, and Beamer, 2022, Ecol. Evol., 12 (2: e8574): 1–38, provided molecular evidence that nominal Desmognathus quadramaculatus is composed of 4–7 lineages of which one, other than Desmognathus quadramaculatus, already has a name available.
