The Del Norte salamander (Plethodon elongatus) is a species of salamander in the family Plethodontidae endemic to the United States in southwestern Oregon and northwestern California. [1] [2] [3]
Plethodon elongatus is a medium-sized, slender salamander. Adults are 6–7.5 cm (2.4–3.0 in) from snout to vent, and 11–15 cm (4.3–5.9 in) in total length. Limbs are relatively short; toes are short and slightly webbed. Dorsal coloration is dark brown or black. A reddish or reddish-brown straight-edged mid-dorsal stripe may extend from the head to the tip of the tail; the stripe may be less pronounced in older animals. [3]
P. elongatus is a fully terrestrial salamander. Clutch size is three to 11 eggs (mean eight). No free-living larval stage exists, and juveniles hatch completely metamorphosed, measuring about 18 mm (0.71 in) in snout–vent length. [3]
The species occurs in areas of moist talus and rocky substrates in redwood or Douglas fir forests. It is typically encountered among moss-covered rocks or under bark and other forest litter, usually avoiding very wet areas. [1]
The Del Norte salamander is locally abundant in suitable habitat. It is threatened by habitat loss caused by logging. [1]
The Siskiyou Mountains salamander, also called the Siskiyou Mountain salamander, exists only in isolated locations along the Klamath River in northern California and southern Oregon. It is a close relative of the Del Norte salamander, and some herpetologists believe it may be a subspecies of that animal.
The black-bellied slender salamander is a small species of salamander that is endemic to California.
Van Dyke's salamander is a small woodland salamander in the family Plethodontidae, the lungless salamanders. These animals breathe through their skin and are largely terrestrial. Compared to other salamanders in Plethodon it is relatively stocky with long legs. Usually associated with streams, seepages, and rock outcrops, it is endemic to Washington where it is found in a limited number of small, isolated populations.
The Abe's salamander is a species of salamander in the family Hynobiidae. It is endemic to Japan and known from southwestern Honshu in northern parts of the Fukui, Kyoto, and Hyōgo Prefectures. The specific name abei honours professor Yoshio Abe, a Japanese zoologist.
Leptopelis susanae is a species of frog in the family Arthroleptidae. It is endemic to southwest Ethiopia and known from the Gughe Mountains and Saja Forest. The specific name susanae honours Susan, the wife of the describer, Malcolm Largen. Common names Susan's tree frog and Susana's [sic] forest treefrog have been coined for this species.
Pristimantis eremitus is a species of frog in the family Strabomantidae. It is found in the Cordillera Occidental in north-western Ecuador from the Cotopaxi Province northward and on western slope of the Colombian Massif in the Nariño Department, extreme south-western Colombia. The specific name eremitus is Latin for "lonely" or "solitary" and refers to this species being the only western-Andean species among its closest relatives. Common names Chiriboga robber frog and lonely rainfrog have been coined for it.
Pristimantis luscombei is a species of frog in the family Strabomantidae. It is known from north-eastern Peru, adjacent Amazonian Ecuador, and from Acre state, Brazil. Some of the paratypes were later identified as belonging to another species, described in 2014 as Pristimantis miktos. At the same time, Pristimantis achuar was identified as synonym of Pristimantis luscombei.
Bradytriton is a monotypic genus of salamanders in the family Plethodontidae. it is represented by the species Bradytriton silus, commonly known as the Finca Chiblac salamander, and has been considered the sister taxon of the genus Oedipina. It is found in north-western Guatemala and in Chiapas, south-eastern Mexico.
Álvarez del Toro's hidden salamander, also known as Álvarez del Toro's salamander is a species of salamander in the family Plethodontidae. It is endemic to Mexico where it is known from its type locality near Jitotol as well as a nearby site on the Mexican Plateau in the state of Chiapas.
Dendrotriton cuchumatanus is a species of salamander in the family Plethodontidae. It is endemic to Guatemala and is known from its type locality near San Juan Ixcoy in the Sierra de los Cuchumatanes, and possibly from another, as yet unconfirmed record. Common name forest bromeliad salamander has been coined for it, although it does not seem to inhabit bromeliads.
The Scott Bar salamander is a species of salamander in the family Plethodontidae, endemic to the United States, where it is restricted to a very small range in the Scott River drainage in Siskiyou County, California, at altitudes between 700 and 1,300 metres above sea level. Described in 2005, it is one of the most recently described species in the large genus Plethodon.
Dunn's salamander is a species of salamander in the family Plethodontidae endemic to the western United States.
The Larch Mountain salamander is a species of salamander in the family Plethodontidae endemic to the United States. It occurs in the Cascade Mountains of southern Washington and northern Oregon. In Washington, it occurs from the Columbia River Gorge to just north of Snoqualmie Pass. Its natural habitats are temperate forests and rocky areas. It is threatened by habitat loss.
The red-legged salamander is a species of salamander in the family Plethodontidae. Formerly considered a subspecies of Plethodon jordani, it is native to the mountain forests of the southeastern United States.
The western red-backed salamander is a species of salamander in the family Plethodontidae. The species is found in extreme southwestern Canada and the northwestern United States. The western red-backed salamander is found in temperate rainforests of the Pacific Northwest. It is considered widespread in the region and is not strictly associated with a specific habitat type.
Pseudoeurycea aurantia, commonly known as Peña Verde salamander, is a species of salamander in the family Plethodontidae. It is endemic to Oaxaca, Mexico and only known from its type locality near Peña Verde, which is the northernmost high peak in the Sierra de Juárez.
Pseudoeurycea nigromaculata, commonly known as the black-spotted salamander or black-spotted false brook salamander is a species of salamander in the family Plethodontidae. It is endemic to Veracruz, Mexico, and known from Cerro Chicahuaxtla ) in Cuatlalpan and from Volcán San Martín at elevations of 1,200–1,300 m (3,900–4,300 ft). These separate populations likely represent distinct species.
Pseudoeurycea unguidentis is a species of salamander in the family Plethodontidae. It is endemic to northern Oaxaca, Mexico, where it is known from its type locality, Cerro San Felipe in the Sierra Madre de Oaxaca, and some other mountains, although the identity of animals from these other locations is uncertain. Its common names are claw-toothed salamander, clawtooth false brook salamander, and clawtoed false brook salamander.
Thorius arboreus, commonly known as the arboreal minute salamander, is a species of salamander in the family Plethodontidae. It is endemic to Sierra de Juarez, Oaxaca, Mexico. The specific name arboreus, derives from the Latin word arbor, meaning tree, referring to the arboreal habitat of this species.
