Rhaebo caeruleostictus is a species of toad in the family Bufonidae. It is endemic to Ecuador and occurs along the lower western slope of the Cordillera Occidental at elevations of 40–2,000 m (130–6,560 ft) asl.[1][2][3][4] The specific name caeruleostictus, from Latin caeruleus (=blue) and Greek stiktos (spotted), refers to the bluish colour pattern of this species.[3][5] Accordingly, common name blue-spotted toad has been coined for it.[1][2][4]

Description

[edit]

Males measure 76–81 mm (3.0–3.2 in) and females 72–92 mm (2.8–3.6 in) in snout–vent length.[3][4][5] The Dorsum and sides have blueish-blackish vermiculations on orangish background (this coloration is assumed to be aposematic). The tympanum is not visible.[5] The parotoid glands are large.[4]

Habitat and conservation

[edit]

Its natural habitats are tropical moist forests and cloud forests.[1] It is a terrestrial species that breeds in riparian habitats.[5]

It is a rare species that is threatened by habitat loss caused by agricultural expansion, logging, and wood plantations.[1] It has not been seen since 1997, and it might be extinct.[5]
