Rhombophryne serratopalpebrosa is a species of frog of the Madagascar endemic microhylid subfamily Cophylinae.{{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Microhylidae/Cophylinae/Rhombophryne/Rhombophryne-serratopalpebrosa |title=Rhombophryne serratopalpebrosa (Guibé, 1975) |author=Frost, Darrel R. |year=2015 |work=Amphibian Species of the World: an Online Reference. Version 6.0 |publisher=American Museum of Natural History |access-date=1 May 2015}} 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.{{cite journal|last1=Scherz|first1=Mark D.|last2=Ruthensteiner|first2=Bernhard|last3=Vences|first3=Miguel|last4=Glaw|first4=Frank|title=A new microhylid frog, genus Rhombophryne, from northeastern Madagascar, and a re-description of R. serratopalpebrosa using micro-computed tomography|journal=Zootaxa|date=2014|volume=3860|issue=6|pages=547–560|doi=10.11646/zootaxa.3860.6.3|pmid=25283290|s2cid=24542430|url=http://pdfs.semanticscholar.org/4d13/942c4761bfa4a9a39350695fca96932f118f.pdf|archive-url=https://web.archive.org/web/20190223232640/http://pdfs.semanticscholar.org/4d13/942c4761bfa4a9a39350695fca96932f118f.pdf|url-status=dead|archive-date=2019-02-23}} It is threatened by habitat loss.
Range and distribution
{{Stack|Image:Rhombophryne serratopalpebrosa map-fr.svg}}
Rhombophryne serratopalpebrosa is endemic to the Marojejy massif in northern Madagascar. At present it is only known with certainty from the holotype specimen. Its type locality is at high elevation on the Marojejy massif.{{cite journal|last1=Guibé|first1=J.|title=Batraciens nouveaux de Madagascar|journal=Bulletin du Muséum National d'Histoire Naturelle|date=1975|volume=3|pages=1081–1089}} 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.
Description
The holotype of Rhombophryne serratopalpebrosa measures roughly {{convert|29|mm|abbr=on}} long. Its fingers and toes are unwebbed, and its dorsal skin is grainy. It possesses four spines above each eye, the posterior-most of which is indistinct.
Taxonomy
Rhombophryne serratopalpebrosa was described as a member of the genus Plethodontohyla by Guibé in 1975. Plethodontohyla serratopalpebrosa was transferred to the genus Rhombophryne by Wollenberg and colleagues.{{cite journal|last1=Wollenberg|first1=Katharina C.|last2=Vieites|first2=David R.|last3=van der Meijden|first3=Arie|last4=Glaw|first4=Frank|last5=Cannatella|first5=David C.|last6=Vences|first6=Miguel|title=Patterns of endemism and species richness in Malagasy cophyline frogs support a key role of mountainous areas for speciation|journal=Evolution|date=2008|volume=62|issue=8|pages=1890–1907|doi=10.1111/j.1558-5646.2008.00420.x|pmid=18485110|s2cid=205781693}} The original description was brief, and the species was re-described by Scherz and colleagues in 2014 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{{cite book|last1=Glaw|first1=Frank|last2=Vences|first2=Miguel|title=A Field Guide to the Amphibians and Reptiles of Madagascar|date=2007|publisher=Vences & Glaw GbR|location=Cologne, Germany|isbn=978-3-929449-03-7|page=118|edition=Third}}{{cite journal|last1=Scherz|first1=Mark D.|last2=Ruthensteiner|first2=Bernhard|last3=Vieites|first3=David R.|last4=Vences|first4=Miguel|last5=Glaw|first5=Frank|title=Two new microhylid frogs of the genus Rhombophryne with superciliary spines from the Tsaratanana Massif in northern Madagascar|journal=Herpetologica|date=2015|volume=71|issue=4|pages=310–321|doi=10.1655/HERPETOLOGICA-D-14-00048|s2cid=4288333}}{{Cite journal|last1=Scherz|first1=Mark D.|last2=Hawlitschek|first2=Oliver|last3=Andreone|first3=Franco|last4=Rakotoarison|first4=Andolalao|last5=Vences|first5=Miguel|last6=Glaw|first6=Frank|date=2017-06-06|title=A review of the taxonomy and osteology of the Rhombophryne serratopalpebrosa species group (Anura: Microhylidae) from Madagascar, with comments on the value of volume rendering of micro-CT data to taxonomists|url=http://www.biotaxa.org/Zootaxa/article/view/zootaxa.4273.3.1|journal=Zootaxa|language=en|volume=4273|issue=3|pages=301–340|doi=10.11646/zootaxa.4273.3.1|pmid=28610237|issn=1175-5334}} — together these species form the "Rhombophryne serratopalpebrosa species group". 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, but their relationship is uncertain due to the lack of genetic material from R. serratopalepbrosa.
