Range Description

The specieswas, until relatively recently, known from just one 19th century specimen from southern So Tom, Sao Tom and Prncipe (Steinheimer 2005). It was rediscovered in 1991, close to the rio Xufexufe in the south-west of the island (Sargeant et al. 1992). Since then it was sighted near the Xufexufe in 1997 (Kaestner in litt. 1998; Sinclair in litt. 1998), and sightings continue to be reported from the Xufexufe, Ribeira Peixe (Monte Carmo) and So Miguel areas (N. Borrow in litt. 2003; M. Dallimer in litt. 2002; Olmos and Turshak 2007; F. Olmos in litt. 2007, 2008, Olmos and Turshak 2010). It was previously thought to be restricted to old-growth forest in the southern lowlands of the island, but was found further north and at higher elevations between Santa Maria and Calvrio in 2010 and 2011, with further unconfirmed reports of the species at three nearby sites (Sol et al. 2012), and subsequently confirmed at nearby Formoso Pequeno (R. F. de Lima in litt. 2013). Given the limited area of suitable habitat and the paucity of records it probably has a tiny population, but recent extensions to the known range, elevation and habitat, raise the possibility that the population may prove to be larger than was feared.
