Pseudacris fouquettei

Using mtDNA samples from a large number of localities throughout North America, Lemmon et al. (2007) elucidated the phylogenetic relationships and established the geographic ranges of the trilling chorus frogs (Pseudacris). They redefined the ranges of several taxa and discovered a previously undetected species in the south-central United States (now described as P. fouquettei; Lemmon et al. 2008).

Based on a re-analysis of previously published molecular data, Duellman et al. (2016) restricted the name Pseudacris to eastern and Rocky Mountain species, and allocated the western species, P. cadaverina, P. hypochondriaca, P. regilla, and P. sierra to the genus Hyliola. Based on genome-wide nDNA data, Banker et al. (2020) argued that Hyliola should not be recognized because (a) the genus Pseudacris already is a monophyletic taxon without the change, and (b) the geographic separation rationale cited by Duellman et al. (2016) is insufficient as the sole criterion for splitting a long recognized monophyletic clade, causing unnecessary taxonomic instability. Use of Hyliola has not gained any traction in the systematic community, presumably because of the small number of species involved (Nicholson 2025).

Widespread in south-central United States; abundant; secure.

Range includes the south-central United States in eastern Oklahoma, southeastern Missouri, Arkansas, eastern Texas, Louisiana, and eastern and southern Mississippi (Lemmon et al. 2008).

This species is represented by large number of occurrences (subpopulations) (e.g., see maps in Dundee and Rossman 1989 and Trauth et al. 2004).

No major threats have been identified. This frog tolerates a substantial level of habitat alteration. Various kinds of habitat loss and degradation attributable to human activities (e.g., urbanization, intensive agriculture) undoubtedly have caused localized declines.
