==Description== Males measure {{convert|31|-|35|mm|in|1|abbr=on}} in snout–vent length. The body and head are broad and flat. The eyes are not very protruding. Webbing between the toes is reduced.<ref name="Schiøtz and Westergaard 2000"/> 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.<ref name="African Amphibians"/> Males have a large vocal sac that is bluish when calling, yellow green otherwise.<ref name="Schiøtz and Westergaard 2000"/>
The male advertisement call is a fast series of very loud, harsh clicks, emitted in a somewhat accelerating rhythm.<ref name=AmphibiaWeb/><ref name="African Amphibians"/>
==Habitat and conservation== ''Hyperolius pseudargus'' inhabits open farmland, heavily degraded former forests (farm bush), and montane grasslands at elevations of {{convert|1500|–|1850|m|abbr=on}} above sea level. Breeding takes place in small pools and males call from sedges near water and from floating vegetation.<ref name="iucn status 17 November 2021" />
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.<ref name="iucn status 17 November 2021" />
