We analyzed the advertisement calls of four species of Physalaemus (P. olfersii, P. moreirae, P. bokermanni, and P. jordanensis) from the Brazilian Atlantic Forest. The tadpole of P. olfersii is described for the first time. Calls of all species are composed by just one kind of note. Those of P. olfersii are long (4035 ms), pseudo-pulsed, with dominant frequency around 2375 Hz; 7–10 sidebands are well distinguishable. The calls of P. moreirae are pulsed, with duration about 604 ms, mean dominant frequency around 1369 Hz and 3–5 sidebands. Physalaemus bokermanni has a call structurally different from the other species by the absence of sidebands or harmonics, larger inter-pulse breaks (around 34–42 ms) and a wider frequency range (around 3700 Hz). Calls of P. jordanensis are pulsed and have 7–8 harmonics, last about 1068 ms and dominant frequency around 2742 Hz. Physalaemus olfersii tadpoles show typical features of other Physalaemus larvae, measuring about 19 mm in total length. Our data on call of P. olfersii suggest that a broader taxonomic survey would be worthwhile by revealing that different species are included under this name. Calls of P. moreirae and P. bokermanni, in general, are in agreement with those previously described from other sites, but complementary features are given. Those of Physalaemus jordanensis show some differences in relation to the calls from the type locality, but additional data are still necessary for a taxonomic conclusion.

A New Species

The orchid bee faunas of Floresta Nacional do Rio Preto, Reserva Biológica Córrego Grande, and Reserva Biológica Córrego do Veado, in the northernmost portion of the state of Espírito Santo, southeastern Brazil, were surveyed for orchid bees for the first time. A total of 1,603 males belonging to 24 species were attracted to 16 different scent baits and actively collected with insect nets during 100 hours from December, 2009, to February, 2010. One species of Euglossa, known as strongly dependent on well preserved mature forests, once recorded at the region, was not found in this survey and may indicate the first documented local extinction of an orchid bee species. This species, which Atlantic Forest population has been treated as Euglossa analis Westwood, 1840, is here considered a new species, Euglossa marianae sp. n.

The species of Patrera Simon, 1903 from Brazilian Atlantic Forest biome are revised. With more than 2715 specimens examined, nine species were found and, of these, only one new species is described, Patrera teresopolis n. sp. from state of Rio de Janeiro. The other valid names were described by a single author: Patrera procera (Keyserling, 1891), P. longipes (Keyserling, 1891), P. virgata (Keyserling, 1891), P. cita (Keyserling, 1891), P. tensa (Keyserling, 1891), n. comb., P. opertanea (Keyserling, 1891), n. comb., P. concolor (Keyserling, 1891), n. comb. and P. recentissima (Keyserling, 1891), n. comb. (Later four here transferred from Teudis O. Pickard-Cambridge, 1896) and P. pellucida (Keyserling, 1891), n. comb. (here transferred from Sillus F.O. Pickard-Cambridge, 1900). The males of Patrera opertanea, P. pellucida and P. recentissima are described for the first time. The species Teudis itatiayae Mello-Leitão, 1915 and Sillus delicatus Mello-Leitão, 1922 are synonymized with P. longipes; Osoriella pallidoemanu Mello-Leitão, 1926 is synonymized with P. concolor. All species are described, illustrated and mapped. The known distribution of Patrera procera and P. longipes is expanded to Argentina and that of Patrera procera to Paraguay.

Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

Jurasaidae are a family of neotenic elateroid beetles which was described recently from the Brazilian Atlantic Forest biodiversity hotspot based on three species in two genera. All life stages live in the soil, including the larviform females, and only adult males are able to fly. Here, we report the discovery of two new species, Jurasai miraculum sp. nov. and J. vanini sp. nov., and a new, morphologically remarkable population of J. digitusdei Rosa et al., 2020. Our discovery sheds further light on the diversity and biogeography of the group. Most species of Jurasaidae are known from the rainforest remnants of the Atlantic Forest, but here for the first time we report a jurasaid species from the relatively drier Atlantic Forest/Caatinga transitional zone. Considering our recent findings, minute body size and cryptic lifestyle of all jurasaids, together with potentially high numbers of yet undescribed species of this family from the Atlantic Forest and possibly also other surrounding ecoregions, we call for both field research in potentially suitable localities as well as for a detailed investigation of a massive amount of already collected but still unprocessed materials deposited in a number of Brazilian institutes, laboratories and collections.

The Neotropical tribe Sphaenorhynchini is composed of 15 recognized species commonly named as “lime treefrogs”. Gabohyla pauloalvini occurs in Atlantic Forest lowlands through the states of Bahia and Espírito Santo, Brazil. Based on field observation, literature review, and evaluation of audio files, we conclude that previous bioacoustic descriptions were erroneously assigned to G. pauloalvini. Here, we describe for the first time the advertisement call of G. pauloalvini from two disjunct populations. In addition, we provide new distribution records and an updated map for this species. The advertisement call of G. pauloalvini is composed of 1–5 closely spaced notes, with duration of 0.016–1.976 s, inter-note intervals of 0.340–1.25 s, and an average dominant frequency (= fundamental frequency) of 4966.0 Hz. Harmonics are visible in the spectrogram. Three new populations of G. pauloalvini have been recorded and extended the distribution by 60 km south. Nevertheless, G. pauloalvini is still known only from few localities. We highlight the importance of depositing audio recordings and specimens in scientific collections to promote systematics and natural history studies.

The complex vocalization of Scinax cardosoi (Anura: Hylidae), with comments on advertisement calls in the S. ruber Clade. The complex vocalization of Scinax cardosoi from a population of Minas Gerais in southeastern Brazil is described and compared with available acoustic data for the other species of the S. ruber Clade. Three distinct types of high-pitched, pulsed calls were identified, and are referred to as “short,” “long,” and “trilled” calls. Short calls (16–66 ms) resemble squeaks, and consist of a pulsed signal (8–28 pulses/call) with regular amplitude modulations throughout their duration; the amplitude peak occurs at about the midpoint of the call duration. Long calls (268–518 ms) resemble giggles, and have lower amplitude than short calls; typically, they consist of pulsed note series (1–6 notes/call). Trilled calls resemble insect chirps and have the lowest amplitude of the three call types; they consist of long (1.1–3.0 s) pulsed note series (9–25 notes/call). Acoustic data are taxonomically informative in the Scinax ruber Clade and provide phenotypic characters diagnosing S. cardosoi in addition to those features proposed in its original description. The vocalization repertoire of S. cardosoi resembles the complex vocal repertoires (i.e., multiple call types emitted in variable combinations) of members of the S. catharinae Clade more than some species of the S. ruber Clade, which tend to have simpler call structures (i.e., a single type of multipulsed note).

Abstract In the present study, I propose a new species, Quararibea bovinii, an Atlantic Forest tree. The new taxon occurs in southeastern Brazil, in the states of Espírito Santo, Rio de Janeiro, and São Paulo. It resembles Q. similis in terms of floral morphology and fruit shape, but it is distinguished by the indumenta of leaves, leaf width, and seed shape.

Information on the ecology of lizard species from the Brazilian Atlantic Forest is scarce and almost nothing is known about the ecology of lizards of the genus Enyalius. In this study, we provide information about some aspects of the natural history of E. brasiliensis from an area of Atlantic Forest in Ilha Grande, RJ. Enyalius brasiliensis (N = 15) feeds mainly on arthropods. The most frequent food items were insect larvae, orthopterans, and ants; in terms of volume, larvae and termites were the most important food items; ants and termites were the most numerous prey categories. Two females were reproductive (one had 10 and the other, five vitellogenic follicles); the smallest measured 92.4 mm in SVL. Seven lizards were found on forest leaf litter. The other microhabitats used were vines, fallen logs, branches, and a crevice on a slope.

Predatory Impact

The Buffy-fronted Seedeater Sporophila frontalis (Verreaux, 1869) is frequently found foraging on seeds during ephemeral masting events of bamboos in the Atlantic forest. In the present study, we analyzed the predation activity of S. frontalis on seeds of Merostachys neesii Rupr. during a masting event in an Atlantic forest reserve on southeastern Brazil. We conducted point counts in spots with M. neesii and in spots without bamboos along trails to determine the presence of S. frontalis on M. neesii clumps. Additionally, focal observations on bamboo clumps and seed traps were used to verify the predatory impact of S. frontalis on M. neesii seeds. S. frontalis was present in 6 out 18 point counts in M. neesii clumps. The seedeater behaved territorially in bamboo clumps and presented a mean predation rate of 1.10 bamboo seeds/minute. Seed traps had up to 80% of the seeds predated. The large amount of seeds available during bamboo masting events probably contributes to the maintenance of wandering populations of S. frontalis in the Atlantic forest. On the other hand, the predation of seeds by S. frontalis may reduce the reproductive germination and the propagation of the bamboos whose growth may in turn negatively affect the establishment of other forest species.
