Comprehensive DescriptionRead full entry
A small slender Hyperolius (20-27 mm) from the savanna of the western part of West Africa, the sexes of equal size and with the same pattern. Dorsum with a dark vertebral line and two dark dorsolateral lines delimiting a light line. Pupil horizontal.
Very similar to H. nasutus in many characters such as body dimensions, habitat preference and pattern, with H. nasutus showing a tendency towards the same five dark stripes on the back. The stripes in lamottei, especially in its eastern populations, are however much more distinct, and are also present in females (West African females of H. nasutus are unstriped). The two species are almost sympatric in central Côte dIvoire (near Lamto) without signs of transition. Generally H. lamottei seems to vicariate for H. nasutus.
The tadpole has a tooth formula of 1/1+1,1 which is one tooth row less than other members of the genus.
