Mantidactylus is a genus of frogs from the Madagascar frog family.

features

Although many species of the genus Mantidactylus have already been separated and placed in their own genera, the group is still composed of very different species, which made it necessary to subdivide into sub-genera. The species are rather small to medium-sized, but the species of the nominal subgenus Mantidactylus (Mantidactylus) are an exception. This sub-genus also includes Mantidactylus guttulatus , the largest frog in Madagascar with a head-trunk length of up to 12 centimeters . The representatives of the genus Mantidactylus are usually not as conspicuously colored as the species of the related genus of the Madagascar colored frogs , but rather have camouflage colors . The males do not have rutting callosities, but have femoral glands on the underside of the rear thighs. The hind feet have webbed feet between the toes, the area of ​​which depends on the type and gender.

distribution

The species of the genus Mantidactylus are common on Madagascar and the neighboring islands. The earlier Mantidactylus species Gephyromantis granulatus , which also occurs on Mayotte ( Comoros ) , is placed in a different genus within the subfamily Mantellinae.

Way of life

Most species are ground-dwelling and live along slowly flowing water. They develop through a tadpole stage in the water.

Systematics and taxonomy

The genus Mantidactylus was first described by the herpetologist Boulenger in 1895 . Mantidactylus guttulatus , then still known as Rana guttulata , became the type species of the genus.

External system

For a long time there were very different frog species from different habitats in Madagascar in this genus. Later, however, these were put together into groups of species, which were then raised to their own genera, including the genera Blommersia , Boehmantis , Gephyromantis , Guibemantis , Spinomantis and Wakea , which are now combined in the subfamily Mantellinae .

Subgenera

Six sub-genera are currently distinguished in the genus Mantidactylus :

  • M. (Mantidactylus) Boulenger, 1895
  • M. (Brygoomantis) Dubois, 1992
  • M. (Chonomantis) Glaw & Vences, 1994
  • M. (Hylobatrachus) Laurent, 1943
  • M. (Maitsomantis) Glaw & Vences, 2006
  • M. (Ochthomantis) Glaw & Vences, 1994

species

The genus includes a total of 35 species. There are annually re-discovered some species in the rivers of Madagascar, others are as cryptic species complex by molecular biology isolated methods of externally very similar ways.
