|Scientific Name:||Eurycea naufragia|
|Species Authority:||Chippindale, Price, Wiens and Hillis, 2000|
|Taxonomic Notes:||Salamanders from springs in the vicinity of Lake Georgetown display a unique combination of alleles and have distinctive mtDNA characteristics; possibly they may also be distinguished based on pigmentation characteristics (Chippindale, Hillis and Price 1994). It is regarded as a distinct species by Chippindale, Hillis and Price (1994) and was formally described as Eurycea naufragia by Chippindale et
al. (2000). It was included in E. neotenes by Sweet (1978, 1982).
|Red List Category & Criteria:||Endangered B1ab(iii,v)+2ab(iii,v) ver 3.1|
|Assessor/s:||Geoffrey Hammerson, Paul Chippindale|
|Reviewer/s:||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Endangered, in view of its extent of occurrence of less than 5,000 km2 and area of occupancy of less than 500 km2, with all individuals in fewer than five locations, and a continuing decline in the extent and quality of its habitat, and in the number of mature individuals.
|Range Description:||This species can be found in springs and possibly one cave associated with drainages of the south, middle, and north forks of the San Gabriel River, Williamson County, in the northern Edwards Plateau region of central Texas, USA; populations from the Cowan Creek drainage and from Bat Well in the Berry Creek drainage are provisionally assigned to this species (Chippindale et al. 2000). Cowan Creek drains into Berry Creek, which drains into the San Gabriel River below the city of Georgetown (Chippindale et al. 2000).|

|Population:||The population of this species is apparently declining.|
|Habitat and Ecology:||It is completely aquatic and does not metamorphose. They are known only from the immediate vicinity of spring outflows, under rocks and leaves and in gravel substrate, and from two water-containing caves. Nothing is known of its breeding biology, though some other spring-dwelling species of central Texas Eurycea are thought to deposit eggs in gravel substrates.|
|Major Threat(s):||Populations within the city of Georgetown proper probably are on the brink of extinction (Chippindale et al. 2000). Development of retirement and leisure communities (Sun City Georgetown), and quarrying (Middle Fork San Gabriel River), are taking place near some salamander populations, but currently these do not appear to be a major threat to salamander habitat (Chippindale et al. 2000).|
|Conservation Actions:||This species is not known from any protected areas, and there is a need for improved protection of its habitat. It is a candidate for both state and federal listing.|
