Distribution of Microhylidae (in black) |
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 57 genera and 11 subfamilies.[2]
Evolution
A molecular phylogenetic study by van der Meijden, et al. (2007) has estimated the initial internal divergence of the family Microhylidae to have taken place about 66 million years ago, or immediately after the
Description
As suggested by their name, microhylids are mostly small frogs. Many species are below 1.5 cm (0.59 in) in length, although some species are as large as 9 cm (3.5 in).
Reproduction

Anatomy
The skull has paired palatines and frontoparietals. The facial nerve passes through the anterior acoustic foramen in the auditory capsule; the trigeminal and facial nerve ganglia are fused to form a prootic ganglion. The eight (or seven) presacral holochordal vertebrae are all procoelous except for a biconcave surface on last presacral. The pectoral girdle is firmisternal and some show reduced clavicle and procoracoids. The terminal phalanges are blunt, pointed, or T-shaped. The tadpole lacks keratinized mouth parts and has a large spiracular chamber emptied by a caudomedial spiracle.[4]

Range
Frogs from the Microhylidae occur throughout the tropical and warm temperate regions of North America, South America, Africa, eastern India, Sri Lanka, Southeast Asia, New Guinea, and Australia. Although most are found in tropical or subtropical regions, a few species can be found in arid or nontropical areas. They are the majority of frog species in New Guinea and Madagascar.
The ranges of each subfamily are:[6]
- Hoplophryninae: Africa
- Scaphiophryninae: Madagascar
- Dyscophinae: Madagascar
- Microhylinae: Southeast Asia, East Asia, South Asia
