Dermophis occidentalis is a species of caecilian in the family Dermophiidae. [3] [4] It is endemic to south-western Costa Rica and occurs in the Pacific lowlands and premontane slopes, extending to the western part of the central valley. Its taxonomic status is unclear. [1]

Description

Dermophis occidentalis is a small-sized caecilian measuring 192–235 mm (7.6–9.3 in) in total length. It has 95–112 primary and 29–37 secondary annuli. [5] The body is slender, [2] with its length 30 to 32 times the body width. [5] ). The head is narrow and light grayish tan in color. The body is dorsally lavender plumbeous, turning lighter ventrally. [2]

Habitat and conservation

Dermophis occidentalis occurs in lowland and submontane rainforests at elevations of 365–970 m (1,198–3,182 ft) above sea level. It is a subterranean species that can be found under logs and in leaf litter. It is viviparous. [1]

Dermophis occidentalis is a poorly known species. Deforestation might be a threat to it. Its range overlaps with the Corcovado National Park, among others. [1]

<i>Schistometopum thomense</i> Species of amphibian

Schistometopum thomense is a species of amphibian in the family Dermophiidae, endemic to São Tomé and Ilhéu das Rolas. It is found in most soils on São Tomé, from tropical moist lowland forests to coastal coconut plantations. It is absent only from the driest northern areas of the island. It is typically around 30 cm (12 in) in length, and is often bright yellow. The size of S. thomense can vary throughout São Tomé, however, and it is the only known caecilian to follow Bergmann's rule, which states that a decreasing temperature due to factors such as increasing altitude will cause an increase in the body size of endothermic vertebrate species. The island of São Tomé is a massive shield volcano, and it therefore has differing altitudes throughout the island, potentially resulting in the size diversity of S. thomense. This species may be referred to as the São Tomé caecilian, as the Agua Ize caecilian, or as the island caecilian, or by the local name of cobra bobo.
