Paedophryne

Paedophryne kathismaphlox

Paedophryne is a genus of the family -mouthed ( Microhylidae ) described only in 2010. The genus belongs to the subfamily of Papua - mouthed ( Asterophryinae ).

Features

All six known species of the genus are among the smallest vertebrates in the world. Your head-body lengths range from 7.0 to 11.3 millimeters. The males usually remain smaller than the females.

The types differ in their size. The smallest type is Paedophryne amauensis whose males have a snout-vent length ( SVL) of 7-8 millimeters not exceed. A head -body length of 8.5-9.0 mm in females was dekot In Paedophryne measured, males have not yet been discovered. The females of Paedophryne verrucosa reach a length of 8.8 to 9.3 millimeters, the males of 8.1 to 8.9 millimeters. In Paedophryne kathismaphlox the females are 10.4 to 10.9 mm long, the males up to 10.1 millimeters. Paedophryne oyatabu is still larger, the females of this species reach 11.3 millimeters. The also in the work of Ritt Meyer et al. 2012 newly described species Paedophryne swiftorum reached 8.3 to 8.9 millimeters.

Occurrence

All species of the genus Paedophryne are located in Papua New Guinea and offshore islands. They live on the ground in litter and fallen leaves.

Way of life

They are crepuscular and feed on various invertebrates. Males call in very high tones that are similar to those of stridulierenden insects.

System

The systematic position of the genus is still unclear. A relationship to the genus Cophixalus is suspected. It can be assumed that the differentiation in the genus 23 to 29 million years ago, as part of the present-day island of New Guinea, in which the representatives of the genus are native, a private terrane represented.
