Comment

See accounts by Petranka, 1998, Salamand. U.S. Canada: 220–223, Boundy, 2000, Cat. Am. Amph. Rept., 701: 1–6, and Hansen and Wake, 2005, in Lannoo (ed.), Amph. Declines: 667–669. In the Batrachoseps (Batrachoseps) attenuatus group of Jockusch, Wake, and Yanev, 1998, Contrib. Sci. Nat. Hist. Mus. Los Angeles Co., 472: 1–17, and Jockusch and Wake, 2002, Biol. J. Linn. Soc., 76: 363 (who provided evidence for the likelihood of several new species masquerading under this name). Stebbins, 2003, Field Guide W. Rept. Amph., Ed. 3: 194–195, and Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 255, provided brief accounts, figures, and maps. Martínez-Solano, Jockusch, and Wake, 2007, Mol. Ecol., 16: 4335–4355, provided a phylogeographic study that suggested that nominal Batrachoseps attenuatus is likely a complex composed of at least five species. Highton, 2014, Mol. Phylogenet. Evol., 71: 127–141, suggested on the basis of molecular analysis that there are 39 cryptic species covered under the name Batrachoseps attenuatus.
