Amolops afghanus
The Kachin torrent frog (Amolops afghanus) is a species of true frog native to Myanmar. This medium-sized amphibian is characterized by its broad head, smooth or slightly knobbed skin, and a dark green coloration with mottled patterns on its dorsal side and limbs. It exhibits significant sexual dimorphism in size, with females being considerably larger than males.

About Amolops afghanus
The Kachin Torrent Frog: An Obscure Amphibian from Myanmar
The Kachin torrent frog, scientifically known as Amolops afghanus, is a species of true frog native to Myanmar. Despite its scientific name, which implies origins in Afghanistan, its common name reflects its collection in the Kachin region of Myanmar. This species is considered obscure, with limited information available about its life history and ecology.
Description and Identification
Amolops afghanus is a medium-sized frog, sometimes characterized by a slender build and a distinctly broad head. Its skin is generally described as smooth, though some observations suggest the presence of small knobs on its dorsal surface. The frog typically exhibits a dark green coloration dorsally, adorned with a dark, mottled pattern. Its limbs may feature dark, mottled, or clear bands, with variations noted among individuals. The underside, or ventral side, of the frog is usually light in color. A notable characteristic is the significant sexual dimorphism in size; females are considerably larger, reaching a snout-to-vent length (SVL) of around 8 cm (approximately 3 inches), while males are smaller, with an SVL of about 5 cm (around 2 inches).
Taxonomy and Nomenclature
The taxonomic journey of the Kachin torrent frog has been complex. It was first briefly described in 1858 and placed in the genus Polypedates. Its current designation, Amolops afghanus, was established in 1865 when Edward Drinker Cope transferred it to the genus Amolops. Over time, it was also classified under the genera Ixalus, Rana, and Staurois. In 1966, Robert F. Inger moved it back to the genus Amolops, solidifying its current scientific name. These rearrangements were often based on specific traits observed in its tadpoles, indicating its true placement within the Amolops genus.
Habitat and Ecology
While detailed ecological information is scarce, the common name 'torrent frog' strongly suggests an association with fast-flowing water environments, such as streams and rivers, which are characteristic habitats for many species within the Amolops genus. Specifics about its diet, breeding behavior, and lifespan are not detailed in available records. As with many amphibians, it is presumed to be insectivorous, preying on invertebrates found within its riparian habitat.
