Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA CAUDATA PLETHODONTIDAE

Scientific Name: Eurycea troglodytes
Species Authority: Baker, 1957
Common Name/s:
English – Eurycea Troglodytes Complex
Taxonomic Notes: Sweet (1984) concluded that this species apparently comprises a hybrid swarm resulting from the incorporation of occasional individuals of Eurycea tridentifera into a larger population of E. neotenes. Chippindale et al. (2000) considered additional data and regarded E. troglodytes as a valid complex of more than one species, and not as being of hybrid origin. They noted that the E. troglodytes complex is a heterogeneous group that probably includes several distinct species.

Geographic Range [top]

Range Description: This complex includes populations from a number of discrete localities in Texas in the USA. There are records from the following counties: north-western Medina (although this population has possibly been extirpated), Real, Kerr, Bandera, Edwards, Uvalde, and Gillespie (Chippindale et al. 2000). Some or all of these locations eventually might be recognized as having distinct species.
