Stumpffia is a genus of microhylid frogs that are endemic to Madagascar.{{BioRef|ASW6|title=Stumpffia Boettger, 1881 |url=https://amphibiansoftheworld.amnh.org/Amphibia/Anura/Microhylidae/Cophylinae/Stumpffia |year=2022|access-date=29 June 2022}} They are mostly brown frogs that typically live among leaf litter. S. contumelia has a snout–vent length of about {{cvt|8-9|mm|in}}, making it one of the world's smallest frogs, and several others in the genus are only slightly larger.{{cite web | title=10 Smallest Frogs and Toads in the World | url=https://gonefroggin.com/2017/12/18/10-smallest-frogs-in-the-world/ | date=18 December 2017 | publisher=gonefroggin.com | access-date=28 January 2020 }} The largest species is no more than {{cvt|28|mm|in}}.

The majority of the species have only been described since 2010. Each species has a small range and many are seriously threatened.{{cite web | title=Stumpffia | url=https://www.iucnredlist.org/search?query=Stumpffia | date=28 January 2020 | publisher=IUCN Redlist | access-date=28 January 2020 }}

Taxonomy

Stumpffia was first described from the single species Stumpffia psologlossa Boettger, 1881, based on a single specimen collected on Nosy Be, a large island off the northwest coast of Madagascar, by Antonio Stumpff.{{Cite journal|last=Boettger|first=Oskar|date=1881|title=Diagnoses Reptilium et Batrachiorum novorum ab ill. Antonio Stumpff in insula Nossi Bé Madagascariensi lectorum|journal=Zoologischer Anzeiger|volume=4|pages=358–362}} By 2017, 15 species were recognised. In late 2017, a major revision of the genus was published.{{cite journal|last1=Rakotoarison|first1=A.|last2=Scherz|first2=M.D.|last3=Glaw|first3=F.|last4=Köhler|first4=J|last5=Andreone|first5=F.|last6=Franzen|first6=M.|last7=Glos|first7=J.|last8=Hawlitschek|first8=O.|last9=Jono|first9=T.|last10=Mori|first10=A.|last11=Ndriantsoa|first11=S.H.|last12=Raminosoa Rasoamampionona|first12=N.|last13=Riemann|first13=J.C.|last14=Rödel|first14=M.-O.|last15=Rosa|first15=G.M.|last16=Vieites|first16=D.R.|last17=Crottini|first17=A.|last18=Vences|first18=M.|title=Describing the smaller majority: Integrative fast-track taxonomy reveals twenty-six new species of tiny microhylid frogs (genus Stumpffia) from Madagascar|journal=Vertebrate Zoology|date=2017|volume=67|issue=3|pages=271–398}} This study used integrative taxonomy, i.e. the combination of multiple different datasets, to delimit and describe new species: it combined morphological, morphometric, chromatic (color), bioacoustic (voice), and genetic data to provide new data on the 15 described species of Stumpffia, and describe a further 26 new species.

Debate on synonymy with ''Rhombophryne''

The genus Stumpffia was proposed to be a junior synonym of Rhombophryne in 2016,{{cite journal|last1=Peloso|first1=P. L. V.|last2=Frost|first2=D. R.|last3=Richards|first3=S. J.|last4=Rodrigues|first4=M. T.|last5=Donnellan|first5=S.|last6=Matsui|first6=M.|last7=Raxworhty|first7=C. J.|last8=Biju|first8=S. D.|last9=Lemmon|first9=E. M.|last10=Lemmon|first10=A.

This debate was continued in 2017, with one group of authors continuing to advocate for synonymy of these two genera plus Anilany,{{Cite journal|last1=Peloso|first1=Pedro L.V.|last2=Raxworthy|first2=Christopher J.|last3=Wheeler|first3=Ward C.|last4=Frost|first4=Darrel R.|title=Nomenclatural stability does not justify recognition of paraphyletic taxa: A response to Scherz et al.

(2017)|journal=Salamandra|volume=53|issue=3|pages=479–483}} There was a temporary impasse, wherein the [http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Microhylidae/Cophylinae/Rhombophryne Amphibian Species of the World] database continued to adopt the single-genus taxonomy, and as a result, so too did the IUCN Red List of Endangered Species and other online databases (e.g. iNaturalist) that draw from that resource. Meanwhile, [http://www.amphibiaweb.org AmphibiaWeb] continued to use the three-genus taxonomy, as did the taxonomists working on cophyline systematics,{{Cite journal|last1=Lambert|first1=Shea M.|last2=Hutter|first2=Carl R.|last3=Scherz|first3=Mark D.|date=2017-02-24|title=Diamond in the rough: a new species of fossorial diamond frog (Rhombophryne) from Ranomafana National Park, southeastern Madagascar|journal=Zoosystematics and Evolution|language=en|volume=93|issue=1|pages=143–155|doi=10.3897/zse.93.10188|issn=1860-0743|doi-access=free}}{{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|journal=Zootaxa|language=en|volume=4273|issue=3|pages=301–340|doi=10.11646/zootaxa.4273.3.1|issn=1175-5334|pmid=28610237}} and other groups working more broadly on frog evolution and taxonomy.{{Cite journal|last1=Feng|first1=Yan-Jie|last2=Blackburn|first2=David C.|last3=Liang|first3=Dan|last4=Hillis|first4=David M.|last5=Wake|first5=David B.|last6=Cannatella|first6=David C.|last7=Zhang|first7=Peng|date=2017-07-18|title=Phylogenomics reveals rapid, simultaneous diversification of three major clades of Gondwanan frogs at the Cretaceous–Paleogene boundary|journal=Proceedings of the National Academy of Sciences|volume=114|issue=29|pages=E5864–E5870|doi=10.1073/pnas.1704632114|pmid=28673970|pmc=5530686|doi-access=free}}{{Cite journal|last1=Tu|first1=Na|last2=Yang|first2=MengHua|last3=Liang|first3=Dan|last4=Zhang|first4=Peng|date=September 2018|title=A large-scale phylogeny of Microhylidae inferred from a combined dataset of 121 genes and 427 taxa|journal=Molecular Phylogenetics and Evolution|volume=126|pages=85–91|doi=10.1016/j.ympev.2018.03.036|pmid=29649581|s2cid=5023319 |issn=1055-7903}}

In March 2019, a new genus, Mini, was described for the miniaturised frogs previously confused with Stumpffia that are more closely related to Plethodontohyla.{{Cite journal|last1=Scherz|first1=Mark D.|last2=Hutter|first2=Carl R.|last3=Rakotoarison|first3=Andolalao|last4=Riemann|first4=Jana C.|last5=Rödel|first5=Mark-Oliver|last6=Ndriantsoa|first6=Serge H.|last7=Glos|first7=Julian|last8=Hyde Roberts|first8=Sam|last9=Crottini|first9=Angelica|date=2019-03-27|editor-last=Crowther|editor-first=Mathew S.|title=Morphological and ecological convergence at the lower size limit for vertebrates highlighted by five new miniaturised microhylid frog species from three different Madagascan genera|journal=PLOS ONE|language=en|volume=14|issue=3|pages=e0213314|doi=10.1371/journal.pone.0213314|pmid=30917162|issn=1932-6203|pmc=6436692|bibcode=2019PLoSO..1413314S|doi-access=free}} Evidence in this study, as well as that presented in a paper by Na Tu et al. in 2018, helped to clarify the taxonomic situation, and the [http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Microhylidae/Cophylinae/Rhombophryne Amphibian Species of the World] database reverted to treating Rhombophryne, Anilany, and Stumpffia as valid genera.{{Cite web|url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Microhylidae/Cophylinae/Rhombophryne|title=Rhombophryne Botteger, 1880|last=American Museum of Natural History|website=Amphibian Species of the World 6.0, an online reference|archive-url=https://web.archive.org/web/20190402154429/http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Microhylidae/Cophylinae/Rhombophryne|archive-date=2019-04-02|url-status=dead|access-date=2019-04-02}}

The taxon Stumpffia helenae Vallan, 2000 was transferred to Anilany'' and therefore does not appear on this list.
