Comprehensive DescriptionRead full entry
A small Mantella. Small specimens of slender appearance, large specimens rather stout, 17-24 mm (F 23-24 mm). Head, dorsum and posterior part of flanks yellow, orange or light green, sometimes (mainly in the yellowish specimens) with fine black spots. Sometimes an indistinct dark middorsal line and traces of a diamond marking. Head laterally, and anterior flanks generally black (black pattern can be largely reduced in some specimens), with a sharp dorsolateral colour border. Light frenal stripe present, often interrupted in the yellowish specimens. Bright red flashmarks present. Iris with some light pigment in its upper part. Ventrally black with a variable number and extension of grey to bluish-white or yellowish markings, sometimes fusing to form an irregular network. Horseshoe marking present and mostly distinct, but poorly expressed in some specimens. Hindlimbs sometimes uniformly orange or reddish ventrally, except the red ventral flashmark extension on the tibia. In other specimens, orange colour only present on tibia (except flashmark area); foot, tarsus and femur being black with grey-whitish markings.
Similar species: The colouration of typical M. crocea is unique, but other populations show all intermediates between M. crocea and M. milotympanum. A reliable distinction of these two forms is therefore not possible.
