Djoko Tjahjono Iskandar (born 1950) is an Indonesian herpetologist who studies the amphibians of Southeast Asia and Australasia. He is a professor of biosystematics and ecology at Bandung Institute of Technology in West Java, Indonesia.
Iskandar has been the first to describe many species of amphibian, including the Bornean flat-headed frog ( Barbourula kalimantanensis ) in 1978, [1] [2] and, in 2014, Limnonectes larvaepartus , the only known frog that directly births tadpoles. [3] He is the author of The Amphibians of Java and Bali. [4] The monotypic banded watersnake genus Djokoiskandarus is named in his honour, [5] as are several species of lizard and frog.
Cyrtodactylus is a diverse genus of Asian geckos, commonly known as bent-toed geckos, bow-fingered geckos, and forest geckos. The genus has 354 described species as of 2023, which makes it the largest of all gecko genera.
Oreophryne, the cross frogs, is a genus of microhylid frogs endemic to Southern Philippine, Celebes and the Lesser Sunda Islands, and New Guinea.
Limnonectes is a genus of fork-tongued frogs of about 75 known species, but new ones are still being described occasionally. They are collectively known as fanged frogs because they tend to have unusually large teeth, which are small or absent in other frogs.
The crab-eating frog is a frog native to south-eastern Asia including Taiwan, China, the Philippines and more rarely as far west as Orissa in India. It has also been introduced to Guam, most likely from Taiwan. It inhabits mangrove swamps and marshes and is one of 144 known modern amphibians which can tolerate brief excursions into seawater, and is possibly the only extant marine 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".
Hose's frog is a true frog species with a wide range in Southeast Asia. This species was named after zoologist Charles Hose.
Everett's tree frog or the Timor tree frog is a species of frog in the subfamily Pelodryadinae. The scientific name commemorates the British colonial administrator and zoological collector Alfred Hart Everett.
Limnonectes heinrichi is a species of frog in the family Dicroglossidae. It is endemic to Indonesia, where it occurs on Sulawesi.
Kuhl's creek frog or large-headed frog is a species of frog in the family Dicroglossidae.
Papurana celebensis, also known as the Celebes frog, is a species of true frog in the family Ranidae. Prior to being reclassified into the genus Papurana in 2020, it was referred to as "Hylarana" celebensis. It is endemic to Sulawesi (Celebes), Indonesia. It is a lowland forest species, also occurring disturbed habitats.
Papurana elberti is a species of true frog. It is native to Indonesia and Timor-Leste and found on the islands of Timor and Wetar. The specific name elberti honours Johannes Elbert, a German naturalist who joined an expedition to the Lesser Sunda Islands and Sulawesi in 1910. Common name Lesser Sundas frog has been coined for it.
Hylarana persimilis, commonly known as the Sumatra frog, is a species of true frog in the family Ranidae. It is native to Aceh, Sumatra, Indonesia. It is only known from the holotype collected from a lakeside.
Nyctimystes purpureolatus is a species of frog in the subfamily Pelodryadinae. It is endemic to New Guinea and is known from its type locality on the Tiri River, a small tributary of the Mamberamo River in West Papua, Indonesia, and from three locations in West Sepik Province, Papua New Guinea.
Oreophryne furu is a species of microhylid frogs endemic to the Mamberamo River basin in Papua, Western New Guinea. It is distinguished from other related species by its small size, unique call and egg-guarding behaviour.
Polypedates iskandari is a species of frogs in the family Rhacophoridae. It is endemic to Sulawesi, Indonesia. It belongs to the Polypedates leucomystax species complex; it was split from Polypedates leucomystax in 2011 based on a morphometric analysis. This split has been challenged because male vocalizations between specimens from Sulawesi and Java show only minor differences and because genetic differences are low.
Litoria gasconi is a species of frog in the subfamily Pelodryadinae. It is endemic to New Guinea.
Nyctimystes sauroni is a species of tree frog in the subfamily Pelodryadinae. It is endemic to Papua New Guinea. Scientists know it solely from the Kikori Integrate Conservation and Development Project area.
