Aphantophryne nana is a species of frog in the family Microhylidae. It is endemic to the Philippines and is known with certainty only from the island of Camiguin. [2] [3] It is unclear whether similar frogs from northeast Mindanao are referable to this species. [1] It was described as Oreophryne nana, but based on molecular data it was moved to Aphantophryne in 2017. [3] [5] Common names Camiguin cross frog, [2] Camiguin narrow-mouthed frog, [6] and volcano cross frog have been coined for the species. [3]

Description

Aphantophryne nana are small, moderately slender-bodied frogs. Adult females in the type series measure 17–20 mm (0.7–0.8 in) in snout–vent length; no males were collected. The head is broader than it is long. The snout is short and bluntly round–pointed. The canthus rostralis is rounded. The tympanum is distinct. The fingers and the toes are dilated into moderately large disks (with the exception of the first finger). Skin is smooth. Preserved specimens are dusky brown, apart from the blackish snout, upper eyelids, and axillary and loreal regions. [4]

Aphantophryne nana differs from Aphantophryne anulata by the absence of subarticular tubercles on the hand, but the diagnostic value of this character has been questioned because specimens from Mindanao show a variable degree of distinctiveness for this trait. [1]

Habitat and conservation

Aphantophryne nana occurs in mossy and montane rainforests. [2] The types were collected in dipterocarp forest at elevations between 550 and 910 m (1,800 and 3,000 ft) above sea level. [4] Eggs presumably belonging to this species have been found under mosses. Development is direct, without a free-living tadpole stage. [2]

Aphantophryne nana is rare on Camiguin. Shifting agriculture and illegal logging threaten its habitat at lower altitudes. [2]

<i>Aphantophryne</i> Genus of amphibians

Aphantophryne is a genus of microhylid frogs found in New Guinea and in Mindanao, the Philippines. Originally described by Fry in 1917, Richard G. Zweifel considered in 1956 Aphantophryne synonymous to Cophixalus. The genus was resurrected in 1989 to house two new species in addition to the type species, A. pansa. A molecular study on the subfamily Asterophryinae in 2017 revealed that two species originally included in the genus Oreophryne were more closely related to Aphantophryne than to other Oreophryne, and were consequently moved to this genus. The study also revealed a number of undescribed species.

<i>Kaloula baleata</i> Species of amphibian

Kaloula baleata, the flower pot toad or sometimes the smooth-fingered narrow-mouthed frog, is a species of narrow-mouthed toad. It is native to India, Borneo, Indochinese Peninsula, Java, Malay Peninsula and Philippines where it lives in lowland rainforests and is tolerant of disturbed sites. The IUCN lists it as being of "Least Concern".

<i>Microhyla chakrapanii</i> Species of frog

Microhyla chakrapanii is a species of frog in the family Microhylidae, the narrow-mouthed frogs. It is endemic to the Andaman Islands. It is also known as the Mayabunder rice frog, Chakrapani's narrow-mouthed frog, and bilateral banded frog. Although morphology suggests association with the Microhyla achatina group, molecular data places it in the Microhyla fissipes group, with Microhyla mymensinghensis as its closest relative.

<i>Pelophryne brevipes</i> Species of amphibian

Pelophryne brevipes is a species of toad in the family Bufonidae. It is endemic to the Philippines and found on the islands of Mindanao and Basilan. Records from elsewhere in Southeast Asia refer to Pelophryne signata or possibly other species. Common names Southeast Asian toadlet and Zamboanga flathead toad have been coined for it.

Hamptophryne alios is a species of frog in the family Microhylidae. It is known from three localities in the southwestern Amazon Basin of Bolivia, Brazil, and Peru. This species used to constitute the monotypic genus Altigius, but molecular phylogenetic analyses have shown it to be close relative of the then-monotypic Hamptophryne, and the two genera have been merged.

<i>Aphantophryne minuta</i> Species of frog

Aphantophryne minuta is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from its type locality near Myola Guest House in the Owen Stanley Range, Northern Province, from another locality in the same province, Mount Tafa; only a single specimen is known from each locality. The specific name minuta refers to the very small size of this species. Common name Myola Guinea frog has been coined for it.

<i>Aphantophryne sabini</i> Species of frog

Aphantophryne sabini is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from the region of its type locality, Myola Guest House in the Owen Stanley Range, Northern Province. The specific name sabini honors Andrew E. Sabin, an American businessman, philanthropist, and environmentalist who joined the expedition during which the holotype of this species was collected. However, its vernacular name Guest House Guinea frog refers to the type locality instead.

<i>Copiula rivularis</i> Species of frog

Copiula rivularis is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and known from near the Indonesian border east to the Morobe Province; it is expected to occur in the Papua province of Indonesia. The specific name comes from the Latin adjective pertaining to small brooks or streams and refers to the habitat of this species. Based on molecular evidence, it was transferred from Austrochaperina to Copiula in 2016.

Kaloula walteri is a species of frog in the family Microhylidae. It is endemic to the Philippines, where it is found in the mountains of southeastern Luzon Island and Polillo Island. The specific name walteri honors Walter C. Brown, an American herpetologist. Common name Walter's narrow-mouthed frog has been proposed for it. Kaloula walteri is most closely related to Kaloula rigida.

Oreophryne anulata is a species of frog in the family Microhylidae. It is endemic to the Philippines and is known from Mindanao, Biliran, Siargao, and Leyte; it probably occurs in some smaller, intervening islands too. Common names Mindanao cross frog and Davao cross frog have been proposed for it; the latter in apparent reference to its type locality, "Davao", even though it probably is in error.

Oreophryne geislerorum is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea where it is known from the northern coast between the tip of the Huon Peninsula and south and east to Kokoda and Popondetta. The specific name geislerorum honours two German taxidermists, Bruno Geisler and his brother Herbert Geisler.

Aphantophryne parkeri is a species of frog in the family Microhylidae. It is endemic to the north coast of New Guinea and only known from Matapan and the Bewani Mountains in the West Sepik Province, Papua New Guinea, and from Sentani in the Papua Province, Western New Guinea (Indonesia). This species was formerly included in the genus Oreophryne, but was in 2017 moved to Aphantophryne based on molecular data. The specific name parkeri honours Hampton Wildman Parker, an English zoologist and herpetologist. Common name Parker's cross frog has been coined for it.

Oreophryne wolterstorffi is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from a single specimen collected from "Deutsch-Neu-Guinea", in what now is Madang Province. Common name Wolterstorff's cross frog has been coined for it.

<i>Nannophrys guentheri</i> Extinct species of amphibian

<i>Platymantis insulatus</i> Species of amphibian

Leptobrachium mangyanorum is a species of frog in the family Megophryidae. It is endemic to the Philippines and known with certainty only from the island of Mindoro, although it might also occur on the nearby Semirara Island. Even though this species was formally described only in 2010, Edward Harrison Taylor had already in 1920s recognized that it is distinct from Leptobrachium hasseltii, the name used for Philippine Leptobrachium at the time. Common name Mindoro litter frog has been coined for this species.
