A little frog leaps a long way: compounded colonizations of the Indian Subcontinent discovered in the tiny Oriental frog genus (Amphibia: Microhylidae).

Frogs of the genus include some of the world's smallest amphibians and represent the largest radiation of Asian microhylids, currently encompassing 50 species, distributed across the Oriental biogeographic region. The genus remains one of the taxonomically most challenging groups of Asian frogs and was found to be paraphyletic with respect to large-sized fossorial . In this study we present a time-calibrated phylogeny for frogs in the genus , and discuss taxonomy, historical biogeography, and morphological evolution of these frogs.
