“…nov." is composed of a complex of species. ABGD analysis underestimated species diversity among species with low divergence and is recommended as a first grouping hypothesis but it is not robust for definitive species delimitation proof (Puillandre et al, 2012;Suárez-Villota et al 2018).…”

Using the nudibranch genus Amphorina as a model, ongoing speciation is demonstrated, as well as how periodic-like patterns in colouration can be included in an integrated method of fine-scale species delimitation. By combining several methods, including BPP analysis and the study of molecular, morphological, and ecological data from a large number of specimens within a broad geographic range from northern Europe to the Mediterranean, five species are recognised within the genus Amphorina, reviewed here for the first time. Two new species from the southwestern coast of Sweden are described, A. viriolasp. nov. and A. andrasp. nov. Evidence is provided of a recent speciation process between the two closely related, yet separate, species which inhabit the same geographic localities, but demonstrate strict water depth differentiation, with one species inhabiting the shallow brackish top layer above the halocline and the other species inhabiting the underlying saltier water. The results presented here are of relevance for currently debated issues such as conservation in relation to speciation, fine species delimitation, and integration of molecular, morphological and ecological information in biodiversity studies. The periodic approach to taxonomy has considerable practical potential for various organismal groups.

“…Temperate forests of southern South America (Chile and Argentina) are home to a reduced but evolutionarily diverse group of amphibians (Formas 1979, Cei 1980, Correa et al 2006, Blotto et al 2013, Streicher et al 2018). The most diversified anuran lineage of these forests is the family Alsodidae, which currently is represented there by two sister genera, Alsodes Bell, 1843 (19 species; Blotto et al 2013, Frost 2019) and Eupsophus Fitzinger, 1843 (11 species; Suárez-Villota et al 2018b). Only Eupsophus (members commonly referred to as “ground frogs”) is found exclusively in temperate forests, inhabiting mainly the forest floor (Rabanal and Nuñez 2008).…”

“…Recently, a controversy about the number of species of Eupsophus has emerged in the literature (Correa et al 2017, Suárez-Villota et al 2018b), according to which there are six or eleven species, respectively. The 11 species of the last taxonomic proposal (Suárez-Villota et al 2018b) are arranged into the two species groups traditionally recognized (Fig. 1): roseus ( E.roseus (Duméril & Bibron, 1841), E.calcaratus (Günther, 1881), E.insularis (Philippi, 1902), E.migueli Formas, 1978, E.contulmoensis Ortiz, Ibarra-Vidal & Formas, 1989, E.nahuelbutensis Ortiz & Ibarra-Vidal, 1992, E.septentrionalis Ibarra-Vidal, Ortiz & Torres-Pérez, 2004, E.altor Nuñez, Rabanal & Formas, 2012, and a putative new species from Villarrica, Chile) and vertebralis ( E.vertebralis Grandison, 1961 and E.emiliopugini Formas, 1989) (Formas 1991, Nuñez 2003, Blotto et al 2013, Suárez-Villota et al 2018b).…”

“…Since 1978, when E.migueli was described (Formas 1978a), the number of species progressively increased to 11 ( E.calcaratus and E.insularis , both revalidated by Formas and Vera 1982, E.contulmoensis , E.emiliopugini , E.nahuelbutensis , E.septentrionalis , E.queulensis and E.altor ), but one of them, E.queulensis , was synonymized with E.septentrionalis by Blotto et al (2013). The number of species was reduced to six by Correa et al (2017), but the more recent proposal (Suárez-Villota et al 2018b) restored the previous taxonomy, adding an additional species not described; so currently the genus is composed of ten nominal species plus an undescribed one (see the taxonomic changes since 1961 in Fig. 1).…”

The genusEupsophus(ground frogs) inhabits exclusively the temperate forests of southern South America (Chile and Argentina). The current delimitation of the genus was reached in the late 1970s, when only two species were recognized, but since then the number of described species steadily increased, reaching a maximum of 11 by 2012. Subsequent studies that applied explicit species delimitation approaches decreased the number of species to six in 2017 and raised it again to 11 the following year, including an undescribed putative species. Despite these taxonomic changes, the two species groups traditionally recognized,roseusandvertebralis, have been maintained. Another recent contribution to the taxonomy of the genus was the explicit recognition of the extremely high level of external phenotypic variation exhibited by species of theroseusgroup, which undermines the utility of some diagnostic characters. Here we provide a critical review of the extensive taxonomic and systematic literature on the genus over the last six decades, to examine the evidence behind the recurrent taxonomic changes and advances in its systematics. We also update and complete a 2017 review of geographic information, provide additional qualitative observations of external characters commonly used in the diagnoses of species of theroseusgroup, and reassess the phylogenetic position of a putative new species from Tolhuaca (Chile), which was not included in the last species delimitation study. The present review shows that: 1) there is no congruence between the patterns of phenotypic and genetic/phylogenetic differentiation among species of both groups; 2) in theroseusgroup, the intraspecific variation in some external characters is as high as the differences described among species; 3) there is little morphological and bioacoustic differentiation within species groups, and inconsistencies in the chromosomal evidence at the genus level; 4) under the latest taxonomic proposal (2018), species of theroseusgroup still lack consistent and reliable diagnoses and their distribution limits are poorly defined; and 5) the population from Tolhuaca represents an additional undescribed species under the most recent taxonomic framework. Finally, we discuss the implications of these findings for the taxonomy and biogeography of the genus, pointing out some areas that require further research to understand their patterns and processes of diversification.
