Hyperolius pseudargus, also known as the Mette's reed frog,[2][3] is a species of frogs in the family Hyperoliidae.[1][2][4][3] It is endemic to south-central Tanzania and occurs in the Udzungwa Mountains and south to Njombe in the Southern Highlands.[1][2] Male Hyperolius pseudargus greatly resemble Hyperolius argus but have less webbing between the toes and the male advertisement call is different.[5] The vernacular name refers to Mette Westergaard, Danish biologist who collected the holotype and is the junior describer of this species.[6]
Description
[edit | edit source]Males measure 31–35 mm (1.2–1.4 in) in snout–vent length. The body and head are broad and flat. The eyes are not very protruding. Webbing between the toes is reduced.[5] The dorsum is green with narrow yellow canthal and dorsolateral stripes, although these may sometimes be indistinct; small yellow dots are usually present. The upper eyelid is yellow or slightly reddish. The ventrum is yellow. The toes and fingers are yellow-green.[3] Males have a large vocal sac that is bluish when calling, yellow green otherwise.[5]
The male advertisement call is a fast series of very loud, harsh clicks, emitted in a somewhat accelerating rhythm.[4][3]
Habitat and conservation
[edit | edit source]Hyperolius pseudargus inhabits open farmland, heavily degraded former forests (farm bush), and montane grasslands at elevations of 1,500–1,850 m (4,920–6,070 ft) above sea level. Breeding takes place in small pools and males call from sedges near water and from floating vegetation.[1]
This species is common. Although its range is small, it is adaptable and is not facing significant threats. It might occur in the Udzungwa Mountains National Park.[1]
