Extreme Miniaturization of a New Amniote Vertebrate and Insights Into the Evolution of Genital Size in Chameleons
www.nature.com/scientificreports OPEN Extreme miniaturization of a new amniote vertebrate and insights into the evolution of genital size in chameleons Frank Glaw1*, Jörn Köhler2, Oliver Hawlitschek3, Fanomezana M. Ratsoavina4, Andolalao Rakotoarison4, Mark D. Scherz5 & Miguel Vences6 Evolutionary reduction of adult body size (miniaturization) has profound consequences for organismal biology and is an important subject of evolutionary research. Based on two individuals we describe a new, extremely miniaturized chameleon, which may be the world’s smallest reptile species. The male holotype of Brookesia nana sp. nov. has a snout–vent length of 13.5 mm (total length 21.6 mm) and has large, apparently fully developed hemipenes, making it apparently the smallest mature male amniote ever recorded. The female paratype measures 19.2 mm snout–vent length (total length 28.9 mm) and a micro-CT scan revealed developing eggs in the body cavity, likewise indicating sexual maturity. The new chameleon is only known from a degraded montane rainforest in northern Madagascar and might be threatened by extinction. Molecular phylogenetic analyses place it as sister to B. karchei, the largest species in the clade of miniaturized Brookesia species, for which we resurrect Evoluticauda Angel, 1942 as subgenus name. The genetic divergence of B. nana sp. nov. is rather strong (9.9‒14.9% to all other Evoluticauda species in the 16S rRNA gene). A comparative study of genital length in Malagasy chameleons revealed a tendency for the smallest chameleons to have the relatively largest hemipenes, which might be a consequence of a reversed sexual size dimorphism with males substantially smaller than females in the smallest species. -

Campo Alegre s/n, 4169-007 Porto, Portugal 5Corresponding author Abstract We describe a new Brookesia species from a forest fragment located 13 km south of Ambalavao in the southern part of Madagascar's central high plateau. Brookesia brunoi sp. nov. is one of the few arid-adapted Brookesia species inhabiting deciduous forests on the western slope of the central high plateau of the island (around 950 m a.s.l.). So far the species has only been observed in the private Anja Reserve. The species belongs to the Brookesia decaryi group formed by arid-adapt- ed Brookesia species of western Madagascar: B. bonsi Ramanantsoa, B. perarmata (Angel), B. brygooi Raxworthy & Nussbaum and B. decaryi Angel. Brookesia brunoi differs from the other four species of the group by a genetic divergence of more than 17.6% in the mitochondrial ND2 gene, and by a combination of morphological characters: (1) nine pairs of laterovertebral pointed tubercles, (2) absence of enlarged pointed tubercles around the vent, (3) presence of poorly defined laterovertebral tubercles along the entire tail, (4) by the configuration of its cephalic crest, and (5) hemipenial morphology. -

E-mail: [email protected] RIASSUNTO Il primo nucleo della collezione erpetologica del Museo Civico di Storia Naturale “Giacomo Doria” di Genova è costituito dalle raccolte effettuate da Giacomo Doria, fondatore del Museo, nella zona di La Spezia, in Persia (oggi Iran) e in Borneo (insieme a Odoardo Beccari) negli anni 1862-1868. Successivamente la collezione viene incrementata col materiale di numerose spedizioni condotte in tutti i conti - nenti; i risultati di tali raccolte sono stati spesso pubblicati sugli “Annali” del Museo. Nella collezione sono pre - senti 593 specie di Anfibi e 1.456 di Rettili; 171 taxa, attualmente validi, sono rappresentati da tipi. Parole chiave: Anfibi, Rettili, Museo di Genova, annali, tipi. ABSTRACT The first nucleus of the herpetological collection of the Museo Civico di Storia Naturale “Giacomo Doria” (Italy, Genoa) was made up of the specimens collected in the years 1862-1868 near La Spezia (Italy, Liguria), in Persia (now Iran) and in Borneo (with Odoardo Beccari) by its founder, Giacomo Doria. Later, it was increased with thousands of specimens collected during several expeditions throughout all the continents. Many important studies about this rich material have been published in “Annali”, the museum’s journal.
