It is considered a rare species, being currently classified as &lsquo;Data Deficient&rsquo; by the IUCN due to the shortage of information about its natural history, ecological requirements, distribution and population trends. In the present study, we aim to fill gaps in the current knowledge of this species by: updating its altitudinal distribution range; describing its release call; providing new natural history data; and describing its karyotype. During fieldwork in the Municipality of Cataguases, Minas Gerais State, we recorded individuals of Z. carvalhoi in three small forest fragments, one of them at only 230 m a.s.l., which now represents the lowest known altitudinal record for this species. In all occasions, we only recorded this frog in calling activity during rainy days, suggesting an opportunistic breeding strategy. Moreover, the karyotype of Z. carvalhoi (2n = 26) is similar to those of other species of the family Cycloramphidae, but it differs remarkably in morphology and fundamental number. The advertisement call presented differences in the spectral structure in comparison to descriptions from other populations. In conclusion, Z. carvalhoi seems to be an explosive breeder occurring along a wide altitudinal range (low- and highland Atlantic Forest), and physical barriers such as mountain chains may not be a constraint to its dispersal. Furthermore, this species represents a promising subject for investigations over both bioacoustics and cytogenetic studies.</p>

We developed a phylogenetic hypothesis based on Bayesian analysis of two nuclear ribosomal and one mitochondrial gene for 118 individuals (84 de novo and 34 from GenBank). These included Gryllacrididae from North, Central, and South America, South Africa and Madagascar, Australia and Papua New Guinea; Stenopelmatidae from North and Central America and South Africa; Anostostomatidae from North and Central America, Papua New Guinea, New Zealand, Australia, and South Africa; members of the Australian endemic Cooloola (three species); and a representative of Lezina from the Middle East. We also included representatives of all other major ensiferan families: Prophalangopsidae, Rhaphidophoridae, Schizodactylidae, Tettigoniidae, Gryllidae, Gryllotalpidae and Myrmecophilidae and representatives of the suborder Caelifera as outgroups. Bayesian analyses of concatenated sequence data supported a clade of Stenopelmatoidea inclusive of all analyzed members of Gryllacrididae, Stenopelmatidae, Anostostomatidae, Lezina and Cooloola. We found Gryllacrididae worldwide to be monophyletic, while we did not recover a monophyletic Stenopelmatidae nor Anostostomatidae. Australian Cooloola clustered in a clade composed of Australian, New Zealand, and some (but not all) North American Anostostomatidae. Lezina was included in a clade of New World Anostostomatidae. Finally, we compiled and compared karyotypes and sound production characteristics for each supported group. Chromosome number, centromere position, drumming, and stridulation differed among some groups, but also show variation within groups. This preliminary trait information may contribute toward future studies of trait evolution. Despite greater taxon sampling within Stenopelmatoidea than previous efforts, some relationships among the families examined continue to remain elusive.</p>
