Comment

See comments under Necturus alabamensis and Necturus lodingi. Bart, Bailey, Ashton, and Moler, 1997, J. Herpetol., 31: 192-201, suggested that this nominal taxon likely contains more than one species, USA, and suggested that populations on the eastern Gulf slope from Lake Pontchartrain through Ochlockonee river drainages be referred to as "Necturus sp. cf. beyeri". See account by Petranka, 1998, Salamand. U.S. Canada: 419–422. Guyer, 2005, in Lannoo (ed.), Amph. Declines: 867–868, provided a detailed account that summarized the biology and conservation literature. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 220, provided a brief account, photograph, and map. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 127, provided an account of larval morphology and biology. Chabarria, Murray, Moler, Bart, Crother, and Guyer, 2018, J. Zool. Syst. Evol. Res., 56: 352–363, discussed the systematics of this complex, restricting the name Necturus beyeri to western Louisiana and eastern Texas, USA. The authors recognized a (1) Pearl River species from the Pearl River drainage of southeastern Louisiana and south-central Mississippi; and (2) a Mobile River species from the eastern quarter of Mississippi through central and northern Alabama to northeastern Georgia, USA.
