A small, very warty Hyperolius from Serengeti, Tanzania. Female 21 mm. Dorsum silvery grey with a white hour-glass pattern. Fingers, toes and ventral surface of hind limbs dark orange, throat and ventrum white. Pupil horizontal.

Only one female and two juveniles are known, collected in the dry season. This form is remarkable on account of its very warty dorsum. From its brief snout, chalky white colour and transverse gular fold in females it would appear to be a member of the H. viridiflavus group but it has been collected together with H. v. goetzei. The known female of H. orkarkarri is small and could well be a subadult. It is relevant that for other members of the viridiflavus group (H. v. nitidulus, Rödel 1996), it is known that juveniles and subadults have very granulated skin in the dry season, while adults have smooth skin. Observations in the wet season would be most desirable to see whether this form is different from the sympatric H. v. goetzei.
