Nanohyla perparva is a diminutive species of frog in the family Microhylidae.[2][3][4] It is endemic to Borneo and found in Kalimantan (Indonesia), Brunei, and Sabah and Sarawak (Malaysia).[1] The nominal species includes distinct lineages that likely represent different species.[2][3] Common names least narrow-mouthed frog[4] and Labang forest rice frog have been proposed for this species.[1][2]
Taxonomy
N. perparva was formerly placed in the genus Microhyla, but a 2021 study using morphological and phylogenetic evidence moved nine species (including N. perparva) to a new genus, Nanohyla.[2][5]
Description
Adult males measure 10.5–11.9 mm (0.4–0.5 in) and adult females 12.4–14.5 mm (0.5–0.6 in) in snout–vent length.[3] The hands have only three fingers. The toe tips are expanded. Colouration consists of shades of brown above, with dark markings on the shoulders and a light band on the flanks.[4]
The tadpoles are very delicate and mostly transparent but appear dark grey when viewed from above. The tail terminates in a flagellum.[4]
Habitat and conservation
Nanohyla perparva occurs in primary lowland rainforests at elevations below 250 m (820 ft). Adults live in the leaf litter and reproduce in both large and small rainwater pools.[1] It can be very abundant after heavy rains when males congregate in water filled depressions and fight for females. The tadpoles are mid-water suspension feeders.[4]
This species is threatened by clear-cutting and conversion of forests into oil palm plantations. It is present in a number of protected areas.[1]
