Microhyla petrigena is a species of frog in the family Microhylidae.[1][2][3] It is found in northern and central Borneo (Brunei, southeastern Sabah and central Sarawak, Malaysia, and central Kalimantan, Indonesia) and in the Sulu Archipelago of the Philippines . Common names pothole narrow-mouthed frog and Kapit rice frog have been coined for it.[1][2]
Description
Microhyla petrigena is a small species of Microhyla: adult males measure 14–16 mm (0.6–0.6 in) and adult females 15–18 mm (0.6–0.7 in) in snout–vent length.[4] The hand has only three fingers. The dorsum is colored in shades of brown. There are dark markings on the shoulder and a light band on the flank.The venter is dark with an irregular white blotch.[3]
The male advertisement call is a single, pulsed note, emitted in series consisting of maximally 15 notes. Call repetition rate is about 0.7 per second, declining towards the end of the series.[4]
Habitat and conservation
Microhyla petrigena occurs in lowland primary rainforests at elevations below 700 m (2,300 ft).[1] It lives in leaf litter. Breeding takes place in small pot-holes on rocky banks of clear streams and rivers and appears to be restricted to certain nights.[1][4] The egg masses float on the surface of these pools.[4] The tadpoles feed in mid-water.[3] This species appears not to be able to adapt to modified habitats. It is threatened by habitat loss caused by logging and conversion in palm oil plantations; the type locality has already been destroyed and species has likely disappeared from there. However, the species occurs in several protected areas.[1]
