Rhombophryne is a genus of the frog from the subfamily of the Madagascar narrow-mouth frogs in the family of the narrow-mouthed frogs .

description

The pupils are horizontal. The tongue is large, elongated, with entire margins and can only be lifted off freely at the sides. There is a longitudinal pit on its top. Palatine teeth are present in an uninterrupted, V-shaped transverse row behind the choans . There is a transverse fold of skin between the tuba eustachii . The eardrum cannot be seen. There is no webbing on the fingers or toes . The tips of the toes are slightly broadened. The coracoid are greatly widened and directed somewhat caudad . The precoracoids are extremely poorly developed. The omosternum is missing. The sternum is a large plate of cartilage. The transverse processes of the sacral vertebra are slightly widened. The bony terminal phalanges of the fingers and toes are simple.

Occurrence

The genus is endemic to Madagascar .

Systematics and taxonomy

The genus Rhombophryne was first described in 1880 by Oskar Boettger .

Molecular genetic work on the systematics of the genus Rhombophryne revealed problems with the monophyly of the group in relation to the genus Stumpffia . According to studies by Peloso et al. In the second quarter of 2015, the reference database “Amphibian Species of the World” merged Rhombophryne with the genus Stumpffia , which was previously regarded as a sister group. Stumpffia , also described by Oskar Boettger in 1881, is therefore only a synonym for the genus Rhombophryne in this online reference .

However, this data was again called into question in 2016 by a new analysis by Scherz and others. The authors point out problems in the data analysis of the earlier work for which, after genetic verification, they blame problems in the identification and attribution of species names to some of the genetic samples. According to these results, amalgamation of the genera is not necessarily justified. Problems with Stumpffia helenae , which differs morphologically from the other species of the genus Stumpffia by well-developed adhesive discs on the fingertips and toes , were solved by the scientists by describing a separate genus for this species, which they named Anilany .

In 2017, Peloso, Frost, and Raxworthy's group referred to the work of Scherz et al. from 2016, which cast doubt on the results of their 2015 study. She comes to the conclusion that even the newly added data from the group around Scherz did not allow any other view of the narrow-mouth frogs living in Madagascar than the study they themselves presented in 2015. Even if the new data were added, no different results would be obtained. The scientists around Peloso accuse the group around Scherz of having accepted paraphyly and giving preference to weak morphological and ecological interpretations over the classical phylogenetic methods.

species

Before merging with the genus Stumpffia in some classifications, the genus Rhombophryne comprised 11 species:

Status: October 16, 2015:

As of April 5, 2019:

In 2015 the number of species increased by three more species:

The following species were first described in 2016:

In 2017 three more species were added:

New in 2019:

  • Rhombophryne proportinalis Scherz, Hutter, Rakotoarison, Riemann, Rödel, Ndriantsoa, ​​Glos, Roberts, Crottini, Vences & Glaw, 2019

As a result, the overall list of the genus Rhombophryne without Plethodontohyla alluaudi and without the 16 original Stumpffia species and Anilany helenae as a type species of its own and without the 26 Stumpffia species described in 2017 currently includes 19 species.
