Oedipina pacificensis is a species of worm salamander in the family Plethodontidae. It is found on the Pacific slope of southwestern Costa Rica and adjacent Panama.[1][2][3] it is morphologically indistinguishable from O. gracilis and O. uniformis, but is genetically clearly distinct.[3]

Description

Adult males measure 26–48 mm (1.0–1.9 in) and adult females 39–51 mm (1.5–2.0 in) in snout–vent length. The tail is longer than the body, such that adults have a total length of 108–175 mm (4.3–6.9 in). The body is very slender and elongate, with short limbs and tiny hands and feet; the digits are syndactylous (fused together). The head is moderately broad with bluntly rounded snout. There are 19–20 costal grooves. Coloration is grayish-black, often with a whitish area near limb insertions or joints. There are also white post-ocular stripes.[3]

Habitat and conservation

Oedipina pacificensis is a leaf-litter inhabitant that is often found near tree buttresses. It occurs in lowland moist and wet forests and premontane rainforest at elevations of 5–1,200 m (16–3,937 ft) above sea level. Development is direct[1][3] (i.e., there is no free-living larval stage[4]). It is a common species that can adapt to disturbed habitats. It is facing no major threats. It occurs in a number of protected areas in Costa Rica.[1]
