Pseudacris triseriata (Wied, 1838)
Western Chorus Frog
Michael J. Lannoo2
"subspecies" of the Pseudacris triseriata complex currently
recognized by Conant and Collins (1998), including P. feriarum
(southeastern chorus frogs), were initially characterized based on color pattern and
morphological variation across their geographic distribution (Smith and Smith, 1952;
Harper, 1955; Smith, 1956). Platz and Forester (1988) and Platz (1989) elevated
the "subspecies" to specific status using morphometric data and advertisement
call characters. However, recent phylogenetic analyses based on DNA sequence data
indicate that the currently drawn range borders of subspecies in the triseriata
complex do not reflect the distributions of true evolutionary lineages (Moriarty and
Cannatella, in preparation). Because the identity and distributions
of these anurans have not been resolved, we consider the members of this group together
under a Pseudacris triseriata complex account.
