New or rare frogs from the Coastal Ranges of Brazil: eleutherodactylus venancioi n.sp., E. hoehnei n.sp. Holoaden bradei n.sp. e H. lüderwaldti Mir. Rib., 1920

Abstract

Field-work in the sierras near the sea-board of south-eastern Brazil continues to yield new or rare frogs. Four more of these forms are presented here. Two of them, both new, are put into the genus Eleutherodactylus, to which they belong by their general habitat, morphology, and also by the osteological characters. They differs from the known regional species of this genus only by the wider and shorter disks of some of the digits and the more lanceolate build. The other two species belong to the very little known genus Holoaden, established by MIRANDA RIBEIRO in 1920. One of them is his type-species, H. lüderwaldti, which continues to be very rare. The other, H. bradei, is new. It seems endemic to the Upper Itatiaia and is very plentiful there.

Molecular phylogeny of Ischnocnema (Anura: Brachycephalidae) with the redefinition of its series and the description of two new species

“…Dorsum can also be finely tuberculate. Lutz (1958) stated, and we confirm, that I. venancioi has three dorsal patterns: one with "longitudinal bands of diverse tones" (Fig. 4A;Figs.…”

“…Remarks: Lutz (1958) had already grouped the species of this series, and described I. venancioi and I. hoehnei in the same paper. All subsequent phylogenetic hypotheses including both species have recovered them as sister taxa Taucce et al, 2018).…”

“…However, because we are using an integrative approach and our only specimen from this population has no recorded advertisement call, we do not describe it as new species. The original descriptions of I. venancioi and I. hoehnei are good and were made with care at the time (Lutz, 1958), but to bring the descriptions to a modern context and to enhance comparisons, we redescribe both species. We then describe the populations from Santa Teresa and from the highelevation grasslands of PARNASO as new species, since there is no available name for them.…”

“…Content: The taxon contains four species: I. venancioi (Lutz, 1958), I. hoehnei (Lutz, 1958), I. parnaso sp. nov., and I. colibri sp.…”

“…Advertisement call: Not formally described. In the original description (Lutz, 1958) the sound is described as a "crrr crrr", which makes sense when you listen to the calls of the other species in the I. venancioi series (described below).…”
