“…It can be large and conspicuous, as in the members of the I. parva, I. guentheri, and I. venancioi series, and also I. surda (member of the I. verrucosa series; Brusquetti et al, 2013;Taucce et al, 2018; this study); minute, as in I. randorum (Heyer, 1985); faint and translucent, as in I. karst, I. nigriventris, and I. vizottoi (Martins and Haddad, 2010;Berneck et al, 2013); and even reduced to some white granules as in I. holti (Targino and Carvalho-e-Silva, 2008). The nuptial pad is absent from the remaining species of the I. verrucosa series (Hedges et al, 2008), from I. melanopygia and I. spanios, of the I. lactea series (Heyer, 1985;Targino et al, 2009), from I. manezinho (Garcia, 1996), from I. nanahallux (Brusquetti et al, 2013), and from I. sambaqui (Castanho and Haddad, 2000). Taucce et al (2018) also recovered a grouping of the I. parva and the I. guentheri (including the I. venancioi series) species series.…”

We present a new phylogenetic hypothesis for Ischnocnema, a Neotropical brachycephaloid genus of ground-dwelling direct-developing frogs. We performed Bayesian inference, maximum likelihood, and maximum parsimony analyses using two nuclear (RAG1 and Tyr) and three mitochondrial genes (12S rRNA, tRNA-Val, and 16S rRNA) in a matrix comprising more than 80% of the described species. We recover Ischnocnema nanahallux outside the Ischnocnema parva series, and it is now unassigned to any species series, nor are Ischnocnema manezinho and Ischnocnema sambaqui. We propose the Ischnocnema venancioi species series to comprise Ischnocnema venancioi, Ischnocnema hoehnei, and two new species described herein (Ischnocnema parnaso sp. nov. and Ischnocnema colibri sp. nov.). Furthermore, we designate a lectotype for I. venancioi. The nuptial pad present in males is an important character in the genus, and having a large, conspicuous, and glandular-appearing nuptial pad seems to be a synapomorphy for the clade composed of the I. parva, Ischnocnema guentheri, and the newly proposed I. venancioi series.

We verified conservation status of endemic species from the Serra da Mantiqueira complex, Serra da Canastra and south of Serra do Werner 1903, Lutz 1926, Cochran 1938, 1948, Lutz and Carvalho 1958, Lutz 1968a, IBDF 1982, Heyer 1983, Izecksohn and Gouvêa 1987, Peixoto 1989, Peixoto and Cruz 1992, Haddad and Pombal Jr 1995, Caramaschi and Cruz 2004, Targino et al 2009, Pimenta et al 2014b Pedra To show biogeographic patterns and areas of endemism of the regions, we first used traditional methods which involve the mapping and superposition of species distributions. We considered an area of endemism when there were at least two species that had restricted distribution, or did not occur in any other area.…”

Biogeographic tools support spatial distribution pattern hypotheses and help to determine priority areas for conservation. Our aim was to verify biogeographic patterns for anurans in three mountain complexes in southeastern Brazil, as well as to discuss the status of species conservation recorded and the biogeographical units evaluated. We selected 16 areas distributed in the Serra da Mantiqueira complex, south of Serra do Espinhaço and Serra da Canastra. We used the occurrence (geographic coordinates) of each species in the localities to determine areas of endemism applying the Endemicity Analysis method. We also tested whether similarity between areas was explained by geographic distance (Multiple Regression on distance Matrices-MRM). The Serra do Itatiaia, Serra da Canastra, Plateau of Poços de Caldas and Serra do Cipó were the areas that presented the highest number of species restricted to them. Through the Endemicity Analysis, we identified four areas of endemism with higher scores. The MRM revealed that the geographic distance explained 41% of species dissimilarity between areas. Most of the endemic species from these areas have inaccurate conservation statuses (data deficient or unevaluated). These results highlight the need for greater research efforts towards understanding species restricted by distribution, as well as the priority in conserving these endemic areas.

“…The specimens we collected share the following characters with them: series of warty tubercles on the upper eyelid and dorsum; presence of prominent calcar on the heels; and the expanded emarginated disks, with ungual flap notched in dorsal view. There are three species of the Ischnocnema lactea species series in Itatiaia, I. melanopygia, I. concolor, and I. holti (Targino & Carvalho-e-Silva, 2008;Targino et al 2009). The illustrated specimen (Fig.…”

Besides its brief original description in 1925 and information provided by one specimen collected in the 1980s, nothing else is known for Ischnocnema nigriventris (Lutz, 1925). Also, the poor preservation of the type series has hindered the association of this name with any known population of Ischnocnema. Fieldwork in Bertioga municipality, state of São Paulo, Brazil, revealed a population of Ischnocnema to which we were able to apply the name Ischnocnema nigriventris. We report this rediscovery, re-describe the species on the basis of the newly found specimens, and describe its mating call. Ischnocnema nigriventris is allocated to the Ischnocnema lactea species series and we propose a diagnosis based on a combination of morphological character states. The species is diagnosed by prominent conical tubercles on the upper eyelid, inguinal region and hidden areas of the hind limbs with yellow mottling in males and orange mottling in females, and by its advertisement call composed of two to four non-pulsed notes, the first one differentiated from the others by its lower intensity and different frequency. Ischnocnema nigriventris is only known from Parque das Neblinas (Bertioga municipality), Paranapiacaba (Santo André municipality), and Boracéia (Salesópolis municipality), localities in the state of São Paulo, Brazil
