Geographic Distribution(1)

Distribution and natural history. — Adelophrŋne nordestina sp. nov. is known from interior Atlantic Forest fragments in Alagoas, Pernambuco, and Paraíba states, Brazil (Fig. 7). These fragments of forest are located in the Pernambuco Endemism Center (Prance 1982), a region very threatened by deforestation and the least studied part of the Atlantic Forest domain, located near the northern portion of the São Francisco River (Tabarelli et al. 2006). Adelophrŋne nordestina sp. nov. is a cryptic species associated with leaf litter. In the type locality (ESEC Murici), individuals of A. nordestina sp. nov. were generally found in humid sites with abundant leaf litter having a depth of 10 – 30 cm. In Pernambuco and Paraíba states, the new species was found in similar habitat conditions as in the type locality. This species is common and active during the day, and its reproduction period appears to be continuous because males were found calling continuously from January to December at temperatures between 21 and 26 ° C. Calling males were found under leaves. The daily vocalization period began around 0830 h, with activity reaching its peak between 1130 h and 1330 h, and usually ending around 1730 h (sunset). Some individuals were observed calling until 2200 h during rain events. The vocalization of one male would often stimulate neighboring males to call, resulting in synchronized alternation in the emission of vocalizations. Egg clutches or females with oocytes were not found.
