Arthroleptis

Schoutedenella De Witte, 1921 Arthroleptis is a genus of frogs in the family Arthroleptidae found in tropical sub-Saharan Africa.

[1][2] Their common names include screeching frogs, sometimes simply squeakers.

[1] These species are terrestrial breeding, with direct development (metamorphosis to froglets occurs within the egg).

Many species in this genus are small, or very small, frogs with a minimum adult size of 15 mm (0.59 in) snout-vent length.

It was hypothesized that small species evolved from larger ones, but in fact the opposite seems to be case.
