Feihyla inexpectata is a species of frog in the family Rhacophoridae. [2] This recently (2014) described species [1] is endemic to Malaysian Borneo and known from its type locality in the Maliau Basin Conservation Area, Sandakan Division, Sabah [1] [2] and from Danum Valley, also in Sabah. [3] Common name Bornean opposite-fingered tree frog has been coined for it. [1]

Etymology

The specific name inexpectata is Latin and refers to the fact that finding a species of the genus Chiromantis, as the species was originally assigned to, was considered unexpected in Borneo given that the genus was previously only known from continental South-East Asia. [1]

Chiromantis inexpectatus is only known from two locations in Sabah, Borneo.

Description

The type series consists of two adult males and a metamorphosing juvenile. The adult males measured 22.2–22.4 mm (0.87–0.88 in) in snout–vent length (SVL). The metamorph measured 17.9 mm (0.70 in) SVL and had a tiny tail stump. [1] Females are unknown. [1] [3]

The head is wider than the body. The snout is truncated in the side view and sloping anteroventrally. The canthus rostralis is rounded. The eyes are large and protuberant. The tympanumis distinct and subcircular (not visible in the metamorph). The forelimbs are long and relatively robust. The fingers have expanded discs and are less than half-webbed (no webbing at all between the first two fingers). The hindlimbs are comparatively short (though still longer than the body). The toes bear expanded discs and are webbed. Skin is smooth except for some minute, blunt asperities in the back. The coloration is changeable, varying between whitish-yellow on body and pinkish on limbs to light brown. There are scattered, small dark-brown spots on the back. A dark lateral band runs from the tip of the snout over upper half of tympanum to about one-half way down the body and is bordered under by a narrower white stripe. The ventrum is semitransparent and immaculate creamy white. [1]

Habitat

The type series was collected at night when the frogs were perching on leaves of low trees (no higher than 1 metre) that extended above the surface of a shallow pool at an elevation of 1,050 m (3,440 ft) above sea level. Neither tadpole, egg masses, nor calling males were found, suggesting that breeding takes place at other times of the year than the time of observation, early March. Frog species sharing the same habitat included Rhacophorus borneensis , Kurixalus appendiculatus , Polypedates macrotis , and Microhyla petrigena . [1] Rhacophorus borneensis was described based on specimens from the same pool. [1] [4]

Conservation

As of late 2017, the species has not been assessed by the International Union for Conservation of Nature. [5] The type locality, Maliau Basin Conservation Area, is not easy accessible. [1]

<i>Rhacophorus</i> Genus of amphibians

Rhacophorus is a genus of frogs in the shrub-frog family Rhacophoridae, which, with the related Hylidae, is one of the two genera of true tree frogs. They are found in China, India, Japan, and throughout Southeast Asia, including the island of Borneo. Over 40 species are currently recognised.

<i>Polypedates</i> Genus of amphibians

Polypedates is a genus of frogs in the family Rhacophoridae, the shrub frogs and Paleotropic tree frogs. They belong to subfamily Rhacophorinae. Members of this genus are collectively known as whipping frogs. They occur in eastern and southern Asia.

<i>Meristogenys</i> Genus of amphibians

Meristogenys is a genus of true frogs from Borneo. Its tadpoles are adapted to fast-flowing mountain streams and easily recognizable by their divided upper lip with ribs on the outside.

<i>Staurois</i> Genus of amphibians

Staurois is a small genus of minuscule true frogs. Most species in the genus are restricted to Borneo, but two species are from the Philippines. This genus is a quite ancient member of the true frog family, Ranidae. They are typically found in or near rapidly flowing, small rocky streams, and are sometimes known as splash frogs or foot-flagging frogs. The latter name refers to their unusual behavior of conspicuously waving their hindlegs and feet, as a way of signalling other members of the species. Similar behavior has also been documented in other frog genera, notably Hylodes and Micrixalus.

<i>Leptobrachium montanum</i> Species of frog

Leptobrachium montanum is a species of frog from the family Megophryidae. It is endemic to Borneo and is, as currently defined, found in Kalimantan (Indonesia), Sabah and Sarawak (Malaysia), and Labi, Belait (Brunei). However, the nominal Leptobrachium montanum is a composed of more than one lineage. Available information mostly refers to this composite rather than the "true" Leptobrachium montanum. Common names montane large-eyed litter frog, mountain spadefoot toad, and mountain litter frog have been coined for it.

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.

Meristogenys amoropalamus is a species of frog in the family Ranidae. It is endemic to northern Borneo and occurs in northwestern Sabah and northeastern Sarawak (Malaysia) and in northeastern Kalimantan (Indonesia). Common names mountain Borneo frog and mountain torrent frog have been coined for it. Studies of its larvae revealed that the nominal species contained two cryptic forms, and in 2011, Shimada and colleagues described Meristogenys dyscritus as a separate species.

<i>Meristogenys jerboa</i> Species of frog

Meristogenys jerboa is a species of frog in the family Ranidae. It is endemic to western Sarawak in Borneo. Common names western torrent frog, Matang torrent frog, and Gunther's Borneo frog have been coined for it. Many cryptic species have been separated from this species. Based on mitochondrial DNA, current "true" Meristogenys jerboa still includes two major lineages. However, because the lineages occur in sympatry and do not differ in morphology, Shimada and colleagues elected to treat them as intraspecific variants.

Meristogenys macrophthalmus is a species of frog in the family Ranidae. It is endemic to Sarawak in northern Borneo (Malaysia) and is only known from its type locality in the Bintulu District. The specific name macrophthalmus is derived from the Greek words macros (="large") and ophthalmos (="eye") and refers to the large eyes of this frog. Common names Matsui's Borneo frog, large-eyed torrent frog, and big-eyed torrent frog have been coined for it.

<i>Buergeria</i> Genus of amphibians

Buergeria is a genus of frogs in the family Rhacophoridae, and the sole genus of subfamily Buergeriinae. They are the sister taxon for all the other rhacophorids. The available firmly supports this position.

Polypedates leucomystax is a species in the shrub frog family Rhacophoridae. It is known under numerous common names, including common tree frog, four-lined tree frog, golden tree frog or striped tree frog. Many past authors have united it with the common Indian tree frog in P. maculatus, but today they are generally considered distinct species. In its native range, it is also called "white-lipped tree frog", but this name is otherwise applied to a species of true tree frogs.

Leptomantis gauni is a species of frog in the family Rhacophoridae. It is endemic to Borneo and is found in Sabah and central Sarawak (Malaysia), Brunei, and north-eastern Kalimantan (Indonesia). The specific name gauni honours Gaun Sureng, a collector for the Sarawak Museum and a companion to Robert F. Inger on field trips when this species was observed. Common names short-nosed tree frog and Inger's flying frog have been coined for it.

<i>Feihyla</i> Genus of frogs

Feihyla is a genus of frogs in the family Rhacophoridae, subfamily Rhacophorinae. They are found in southern China and Vietnam, and likely also in Laos. Its phylogenetic position is not yet fully resolved, but it is probably the sister taxon to Taruga, Polypedates, and Rhacophorus. Feihyla was originally erected to resolve polyphyly of Chirixalus by absorbing "Chirixalus palpebralis".
