Abstract

By using integrative taxonomy, we describe a new species of terrestrial foam-nesting frog of the genus Adenomera from white-sand forests of the Rio Negro Sustainable Development Reserve, Central Amazonia, Brazil. Within the A. andreae clade, the new species belongs to the A. simonstuarti complex where it is sister to the lineage from the lower Juruá River. The new species is assigned to the genus Adenomera by having adult SVL smaller than 34.1 mm, by its lack of fringing and webbing between toes and by the absence of spines on the thumb of adult males. It differs from other Adenomera by the following combination of characters: antebrachial tubercle absent; toe tips flattened or slightly flattened, with visible expansions; nearly solid, dark-coloured stripe on underside of forearm; single-note advertisement call; notes formed by 11–21 incomplete pulses; call duration varying between 100 and 199 ms; fundamental frequency 1,765–2,239 Hz; dominant frequency 3,448–4,349 Hz; and endotrophic tadpoles with spiracle present and labial teeth absent. Over the last decade, we have inventoried many permanent sampling modules in ombrophilous forests in the Manaus Region and in the Purus-Madeira interfluve, but the new species was found only in the white-sand forest from West Negro-Solimões Interfluve. Adenomera sp. nov. may be endemic to, or at least a specialist in, this environment.
