Rhombophryne serratopalpebrosa is a species of frog of the Madagascar endemic microhylid subfamily Cophylinae. [2] Genetic evidence revealed that it is a species complex, in need of resolution. This work has made significant progress, and five related species have been described from this complex between 2014 and 2017. [3] [4] [5] It is threatened by habitat loss. [3] [5] [1]

Rhombophryne serratopalpebrosa is endemic to the Marojejy massif in northern Madagascar. At present it is only known with certainty from the holotype specimen. [3] Its type locality is at high elevation on the Marojejy massif. [6] Records from outside of Marojejy National Park may refer to other species, and at present this species has only been confirmed from this single location. [3]

Description

The holotype of Rhombophryne serratopalpebrosa measures roughly 29 mm (1.1 in) long. Its fingers and toes are unwebbed, and its dorsal skin is grainy. [3] It possesses four spines above each eye, the posterior-most of which is indistinct. [3]

Taxonomy

Rhombophryne serratopalpebrosa was described as a member of the genus Plethodontohyla by Guibé in 1975. [6] Plethodontohyla serratopalpebrosa was transferred to the genus Rhombophryne by Wollenberg and colleagues. [7] The original description was brief, and the species was re-described by Scherz and colleagues in 2014 [3] to facilitate a review of the R. serratopalpebrosa species complex.

The closest related species of Rhombophryne share also the superciliary spines: Rhombophryne vaventy , R. coronata , R. ornata , R. tany, R. regalis , and R. diadema [3] [8] [4] [5] — together these species form the "Rhombophryne serratopalpebrosa species group". [4] [5] The closest relative is suspected to be R. regalis , which is smaller but shares certain morphological characters such as an s-shaped fold posterior to the nostril, [5] but their relationship is uncertain due to the lack of genetic material from R. serratopalepbrosa. [5]
