Hyperolius guttulatus is a species of frog in the family Hyperoliidae.[1][2][3][4][5] It occurs in West and Middle Africa between Sierra Leone in the west and Gabon in the east/south.[1][2] Common name dotted reed frog has been coined for this species.[2][3]

Distribution

The species is found, from west to east, in Sierra Leone, Guinea, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, and western Gabon.[1][2][5] It probably occurs in mainland Equatorial Guinea, whereas the gap in Benin might be real.[1]

Description

Hyperolius guttulatus is a relatively large member of its genus, with males measuring 27–35 mm (1.1–1.4 in) and females 29–37 mm (1.1–1.5 in) in snout–vent length. The body is broad and flat and there is a conspicuous dark canthal stripe. The pupil is horizontal. Males have a large gular flap. There are two colour phases:

Male advertisement call is a rapid succession of pure, low-pitched notes that have a soft tonal quality.[3][4]

Habitat and conservation

Hyperolius guttulatus lives in and around large swamps in secondary habitats in the forest belt; in West Africa it typically occurs in the forest-savanna transition forest. It is not found in undisturbed forest. Breeding takes place very large, mostly permanent ponds.[1] Males call from bushes several metres above the ground.[3][4]

The distribution of this species is very patchy, but it can be locally very abundant. It is threatened by habitat loss, especially when affecting its breeding sites. It occurs in a number of protected areas,[1] including the Ankasa Conservation Area and Kakum National Park in Ghana.[5]
