Herpetology Notes, volume 13: 997-1002 (2020) (published online on 01 December 2020) New records of anuran amphibians from the Pedra Talhada Biological Reserve, a Seasonal Semideciduous Atlantic Forest fragment in northeastern Brazil Marcos Jorge Matias Dubeux1,2,3,*, Ubiratan Gonçalves2,3, Matheus Eduardo Bastos Ramos2,3, Aline Henrique de Melo2,3, Anita da Silva4, and Tamí Mott2,3 Despite centuries of destruction, the Atlantic Forest al., 2006; Ribeiro et al., 2009). Nevertheless, 77 species ecoregion of South America is considered a global of anuran amphibians have been catalogued in this area biodiversity hotspot (Myers et al., 2000). The remaining (Dubeux et al., 2020), 14 of which are endemic, and forest is still remarkably diverse and among the eight seven classified as endangered (ICMBio, 2018; IUCN, recognised sub-regions, there is considerable variation 2020). in human impact, conservation efforts and biological The Pedra Talhada Biological Reserve (PTBR) was knowledge (Silva and Casteleti, 2003; Tabarelli et created in 1989 and is one of the few areas in the BSR al., 2006; Ribeiro et al., 2009). The Pernambuco Pernambuco to be the subject of long-term studies of Biogeographical Sub-Region (BSR Pernambuco; sensu several taxa (Studer et al., 2015). This conservation Ribeiro et al., 2009) located north of the São Francisco unit covers 45 km2 of mainly semideciduous seasonal River (covering the latitudinal range of 5.2500ºS– forests with an altitudinal range from 459 to 883 meters 10.5000ºS) suffers from high anthropogenic impacts, (Tscharner et al., 2015). It is located on the border of low knowledge and few conservation initiatives. This the states of Pernambuco and Alagoas and covers sub-region contains just a few isolated fragments (<100 the municipalities of Quebrangulo and Chã Preta in km2, Ribeiro et al., 2009) and contains only 120 of 1,437 Alagoas and Lagoa do Ouro in Pernambuco (9.1830ºS Atlantic Forest Conservation Units (UCs) (CNUC/ to 9.2660ºS, and 36.3660ºW to 36.4660ºW). The area MMA, 2020) - less than 1% of its current coverage is stands out for its rich hydrography - it contains more protected (Ribeiro et al., 2009). than 168 springs, and numerous reservoirs, streams and This BSR Pernambuco has historically received less dams (Tscharner et al., 2015). The climate is classified attention from naturalists and researchers in comparison as tropical with dry summers; annual temperature range with other sub-regions and, consequently, is the least is 22–24 °C and annual rainfall of 1,000–1,300 mm known of the remaining forest remnants (Tabarelli et (Alvarez et al., 2013). Carvalho-e-Silva et al. (2015) recorded 42 species of 10 families of anuran amphibians for PTBR. This remarkably rich anuran assemblage represents one of the highest diversity amphibian communities north of the São Francisco River.

These trips were part of The photo of Sphaenorhynchus prasinus in the a larger project that aims to investigate the presence aforementioned work (see Carvalho-e-Silva et al. of the fungus Batrachochytrium dendrobatidis (Bd) in [2015] figure 6.8.30, page 347) is misleading because it the local anurofauna. During the fieldwork campaign, represents an individual of S. cammaeus, described later individuals of new species for the area or those with from this locality by Roberto et al. (2017). However, taxonomic uncertainties were collected (ICMBio/ the occurrence of S. prasinus in the area was confirmed SISBio 66127). Morphological identification was after the collection of two individuals at the Nordesta performed using the available literature or by contacting lagoon (MUFAL 16115-16; Fig. 1J). Although both specialists in the groups. The taxonomic nomenclature species occur in the PTBR, they are not syntopic, follows Frost (2020) and all collected specimens were occupying distinct regions of the conservation unit. deposited in the Coleção Herpetológica do Museu de Sphaenorhynchus prasinus has been found in the weirs História Natural da Universidade Federal de Alagoas and wetlands only in the lowland section of the reserve.

During the 14 days of fieldwork we registered In contrast, S. cammaeus only occurs in the weirs of 28 of the 36 specific taxa registered by Carvalho-e-Silva high-altitude areas, ca. 890 m elevation. et al. (2015) (see Appendix 1 for complete list) and nine Leptodactylus latrans and L. macrosternum are the taxa never before registered in the PTBR (Table 1). only nominal species in the L. latrans species group Carvalho-e-Silva et al.
