A total evidence analysis of the phylogeny of hatchet‐faced treefrogs (Anura: Hylidae: Sphaenorhynchus)

The Neotropical hylid genus Sphaenorhynchus includes 15 species of small, greenish treefrogs widespread in the Amazon and Orinoco basins, and in the Atlantic Forest of Brazil. Although some studies have addressed the phylogenetic relationships of the genus with other hylids using a few exemplar species, its internal relationships remain poorly understood. In order to test its monophyly and the relationships among its species, we performed a total evidence phylogenetic analysis of sequences of three mitochondrial and three nuclear genes, and 193 phenotypic characters from all species of Sphaenorhynchus. Our results support the monophyly of Sphaenorhynchus with molecular and phenotypic evidence, with S. pauloalvini as the earliest diverging taxon, followed by S. carneus, as the sister taxon of all remaining species of the genus. We recognize three species groups in Sphaenorhynchus (the S. lacteus, S. planicola and S. platycephalus groups), to facilitate its taxonomic study; only three species (S. carneus, S. pauloalvini and S. prasinus) remain unassigned to any group. Sequence data were not available for only two species (S. bromelicola and S. palustris) for which we scored phenotypic data; wildcard behaviour was detected only in S. bromelicola nested inside the S. platycephalus group. On the basis of the resulting phylogenetic hypothesis, we discuss the evolution of oviposition site and a number of phenotypic characters that could be associated with heterochronic events in the evolutionary history of this group.

“…The vocalization of S. mirim differs from the calls of all other Sphaenorhynchus species by its higher dominant frequency, which is expected as it is the smallest species of the genus. This parameter usually increases Toledo et al (2007) with the decrease of the mass of the vocal cords, which is positively correlated to the overall body size (Martin, 1972). Besides this, the advertisement call of S. mirim can be distinguished from S. caramaschii and S. surdus calls by its shorter duration; from S. palustris by its lower number of pulses/note; from S. prasinus and S. pauloalvini by its lower number of notes.…”

Anuran vocalization is species-specific and bioacoustic analyses are important tools for species delimitation. The present study describes the vocalization of Sphaenorhynchus mirim, recognizing two different types of call, here referred to as call type A and call type B. We analyzed a total of 86 calls of type A and 15 calls of type B. Call type A consists of a single multipulsed note with duration of 34.12-101.00 ms, with 9-25 pulses/note, pulse rate ranges from 240.40-338.21 pulses/sec and the dominant frequency is between 3085.51-3398.86 Hz. We arbitrarily subdivided the type B call into two patterns: Bd (with well-defined notes) and Bnd (with non-defined notes). Call type B with well-defined notes (n = 4) has 3-5 multipulsed notes, duration of 180.12-262.68 ms, note duration of 15.62-100.75 ms, interval between notes with 7.93-23.12 ms, 2-22 pulses/note and dominant frequency of 3067.77-3180.11 Hz. Call type B with non-defined notes (n = 11) has duration of 143.75-218.12 ms; 26-32 pulses/ call and a dominant frequency of 3180.11-3375.22 Hz. Sphaenorhynchus mirim vocalization differs from all other species in the genus by its higher dominant frequency.

state-ofart and perspectives. Biota Neotrop. 11(1a): http://www.biotaneotropica.org.br/v11n1a/en/abstract?inventory +bn0041101a2011Abstract: The last list of species of the state of São Paulo State was updated and totaled 236 species of amphibians, 230 of which are anurans and six are caecilians. Bokermannohyla gouveai and Sphaenorhynchus surdus were removed from this list, because they did not occur in the State of São Paulo. The number of anuran species recorded comprise 27% of the species richness of the country and an increase by 31% in the number of species recorded for the state since 1998. Thus, despite the State of São Paulo be the Brazilian region where the anurans have been most studied, these data show that the number of known species tends to increase in the next years. We have identified two major geographical gaps of inventory: the southwest of the state, especially in the Paranapanema river basin and the northeast region, mainly at the border between the States of Minas Gerais and São Paulo. Although both have been sampled recently, information is still lacking. The current state of knowledge and perspectives in the areas such as taxonomy, systematics, ecology and conservation are evaluated.
