A new species of Elachistocleis (Anura: Microhylidae) from the Andean Yungas of Argentina, with comments on the Elachistocleis ovalis - E. bicolor controversy

Abstract: Elachistocleis skotogaster spec. nov. is described from the Andean Yungas of Argentina. It is unique in the genus in having belly and legs densely spotted with brown, an uniformly dark brown dorsal mottled with black, absence of a light vertebral strip, a fold behind the mouth but not a postcommisural gland. Its natural history and advertisement call are brie y noted. Elachistocleis ovalis and E. bicolor are considered different species, and Buenos Aires, Argentina, is established as type locality for the latt… Show more

“…Species of the genus Elachistocleis are usually associated with open environments (Lavilla et al 2003, Rodrigues et al 2003. And, although E. bicolor foraging habitat was an open area of low herbaceous vegetation, the few frogs that found shelter were found in the adjacent fluvial forest besides the RECU lagoon (E. bicolor refugees in fossae or under fallen logs: Maneyro and Carreira 2012).…”

“…Também foi encontrado dimorfismo semelhante em E. bicolor (Rodrigues et al 2003), em E. erythrogaster (Kwet & Di Bernardo 1999) e em E. skotogaster (Lavilla et al 2003). Dimorfismo sexual com fêmeas maiores do que machos é comum entre anuros (Shine 1979), mas interpretações de como esta característica surgiu são variadas.…”

“…Machos de E. ovalis foram registrados vocalizando em água rasa entre gramíneas com o corpo inclinado, parcialmente imerso (Kwet & Di Bernardo 1999, Achaval & Olmos 2003, Eterovick & Sazima 2004. Outros registros para o gênero incluem E. bicolor (Rodrigues et al, 2003), E. erythrogaster (Kwet & Di Bernardo 1999) e E. skotogaster (Lavilla et al 2003) vocalizando em ambientes e posições semelhantes.…”

“…Although there are many brief treatments of skeletal morphology of American microhylids (Parker 1881, Carvalho 1948, 1954, Walker, 1973, Walker and Duellman 1974, Zweifel 1986, da Silva and Meinhardt 1999, there are few comprehensive studies. To date, there are thorough descriptions of the skeletal morphology in only four generaElachistocleis (Lavilla et al 2003), the monotypic Hamptophryne (de Sá and Trueb 1991), Melan ophryne, and Nelsonophryne (Lehr and Trueb 2007). In addition, Donnelly et al (1990), Haas (2001Haas ( , 2003, Pugener et al (2003) and Vera Candioti (2006Candioti ( , 2007 described and discussed morphological variation of larval characteristics for a number of microhylid genera.…”
