Rana hosei (lapsus)
Rana hosii Boulenger, 1891Hose's Frog, Odorrana hosei, is a true frog species with a wide range in Southeast Asia. This species was named after zoologist Charles Hose.
Its closest living relatives appear to be O. chloronota which occurs to the north of Hose's Frog's range, as well as O. livida and O. morafkai with a more limited range in Myanmar and Vietnam, respectively; these four appear to form a close-knit group wherein the northern species are barely closer to each other than Hose's Frog is to any of them. Also quite closely related is O. megatympanum, another Vietnamese endemic.[1]
Description
This frog has a robust body with long, slender legs; males measure 50–60 mm, females 85-100 mm. The upperparts are dark green with brown sides, the underparts are pale, the limbs are marked with dark crossbars. Its finger- and toe-tips bear grooved discs.
Its tadpoles apparently lack suctorial discs.
Distribution and ecology
Hose's Frog has been recorded from the Malay Peninsula south of the Kra Isthmus, on Phuket, Tioman, Borneo, the Batu Islands, Sumatra, Simeulue[verification needed], Bangka Island, Belitung and Java. It lives in and along clear, swift streams and rivers in rainforest up to 1,700 meters ASL. Though declining in recent times due to deforestation, it is still widely distributed and plentiful, and there is evidence that it is more tolerant of pollution and will morer readily accept secondary forest than many other frogs in the region. It is therefore listed as a Species of Least Concern by the IUCN.[2]
Eggs are probably deposited in water in a way roughly similar to other true frogs. But the eggs inside their gelatinous outer layer are cream-coloured without a dark hemisphere, indicating a specialised oviposition site.
