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]

<i>Nanohyla annamensis</i> Species of amphibian

Nanohyla annamensis, commonly known as the Annam chorus frog, Annam narrow-mouthed frog, Vietnam rice frog or minute narrow-mouthed frog, is a species of frog in the family Microhylidae. It is found in Cambodia, Laos, Thailand, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, swamps, and intermittent freshwater marshes. It is listed as vulnerable by the IUCN Red List due to habitat loss and degradation.

It is found in Peninsular Malaysia; records from Thailand and elsewhere probably refer to other species. Its natural habitats are evergreen submontane and montane rainforests. It lives on the forest floor and in puddles and breeds in temporary pools. It is locally threatened by habitat loss.

Microhyla borneensis, also known as the Matang narrow-mouthed frog, is a species of microhylid frog found in the Matang Range in Sarawak, Borneo. It was once the smallest known frog from the Old World. Adult males of this species have a snout-vent length (SVL) of 10.6–12.8 mm (0.42–0.50 in), but adult males can reach a maximum of 13 mm (0.51 in),and adult females of this species have a snout-vent length of 16–19 mm (0.63–0.75 in), Tadpoles measure just 3 mm.

<i>Micryletta erythropoda</i> Species of frog

Micryletta erythropoda, commonly known as the Mada paddy frog, is a species of frog in the family Microhylidae. It is known from Myanmar, Thailand, and Vietnam. Its natural habitats are swamps, freshwater marshes, and intermittent freshwater marshes. While formerly classified in the genus Microhyla, a 2018 study found it to belong to the genus Micryletta instead. A study performed in 2019 found that several Micryletta populations in southern Myanmar and Thailand that were formerly assigned to M. inornata actually belong to M. erythropoda; prior to this, M. erythropoda was considered endemic to Vietnam.
