Colostethus inguinalis

Colostethus inguinalis is a species of frog in the family Dendrobatidae. It is endemic to northwestern and northcentral Colombia.[1][2][3] Its vernacular name is common rocket frog,[2] although this name can also refer to Colostethus panamansis that until 2004 was considered a junior synonym of Colostethus inguinalis.[4] Much of the older literature on Colostethus inguinalis is actually about Colostethus panamansis.[5]

Description

Adult males measure 22–27 mm (0.87–1.06 in) and adult females 23–30 mm (0.91–1.18 in) in snout–vent length. The tympanum is well-defined and pale anteriorly. An oblique lateral pale line extends halfway from groin to the eye- Adult males with solid black throat, with the black pigmentation usually extending onto the chest and the anterior belly; adult females have white (unpigmented) or faintly pigmented gray or brown chest. The toes are moderately webbed. Adult males have swollen third finger.[5]

Habitat and conservation

Colostethus inguinalis is a diurnal species of humid lowland forests at elevations of 0–400 m (0–1,312 ft)[1] or 300–800 m (980–2,620 ft) above sea level,[3] depending on the source. It often occurs along rocky sections of forest streams. The eggs are laid in leaf litter; the adults carry the tadpoles to streams.[1]

It is an abundant species, but deforestation for agricultural development, logging, human settlement, illegal crops, and pollution resulting from the spraying of illegal crops is a major threat; it is suspected that the overall population is declining. This species can be found in a number of protected areas.[1]
