Comprehensive DescriptionRead full entry
Medium-sized species with slender appearance. 22-29 mm. Head and anterior part of dorsum covered by a sharply delimited yellow/green marking, posteriorly either ending semicircularly or prolonged as a pointed triangle to the cloacal region (not corresponding to sexual dimorphism). Flanks and posterior part of dorsum black. Arms and legs usually black, rarely copper brown. Hands and finger tips often with blue spots. No frenal stripe, but single yellowish spots sometimes present under the eyes. Iris black without light pigment. Venter with small blue or greyish spots, throat generally black without pattern. No red, orange or yellow pattern on hindlimbs.
Similar species: M. betsileo, M. viridis and M. expectata differ by having blue spots on the throat, less extended terminal finger disks and usually a light line along the upper lip. Mantella sp. is similar in colouration but lacks extended finger disks and has a frenal stripe.
