Sanguirana igorota

Sanguirana igorota is a species of true frog, family Ranidae. It is endemic to Cordillera Central of the island of Luzon, Philippines.[1][2] Its closest relative is Sanguirana luzonensis, and it has even been considered synonym of that species;[2] a later study suggests still unresolved relationships between S. igorota, S. luzonensis, and S. tipanan.[3] Common name Taylor's Igorot frog has been coined for this species.[4]

Description

Adult males measure 50–58 mm (2.0–2.3 in) and adult females 68–82 mm (2.7–3.2 in) in snout–vent length.[3] The snout is squarish in dorsal view.[3][5] The tympanum can be translucent.[3] Moderate dorsolateral ridges are present. The dorsum is olive green with bronze spots. The venter is yellow.[3][5] Fine dorsal asperities are present. The groin is tuberculate. No vocal sac is present in males.[3]

Habitat and conservation

Sanguirana igorota occurs in cool streams and rivers in montane rainforest at elevations of 850–950 m (2,790–3,120 ft) above sea level[1] (800–1,300 m (2,600–4,300 ft) in other sources[4]). It can be fairly abundant in suitable habitat and tolerates some habitat disturbance. Presumably, breeding takes place in streams; the eggs are laid in water. It is threatened by habitat loss (deforestation) caused by habitat conversion to agriculture or real estate.[1]
