Adelastes hylonomos Zweifel, 1986

Holotype: AMNH 123696 .

Type locality: “ Near the Neblina Base Camp on the Rio Baria , 140 m elevation, 00°49’50”N, 66°09’40”W, Rio Negro Department, Amazonas Federal Territory, Venezuela.”

Distribution: Region 4. Venezuela, Brazil, and Guyana. Known from type locality at the southern border of Venezuelan Amazonas, from the proximity of Rio Darahá, tributary of the Rio Negro, municipality of Santa Isabel do Rio Negro, State of Amazonas, northern Brazil (0°23’57.58”S, 064°47’12.98”W), and from Guyana, at plateau above Meamu River.

Remarks: Peloso et al. (2016) place Adelastes in its own subfamily Adelastinae . However, we believe it should be relegated as part of Otophryninae , being clustered basally with this last subfamily ( Peloso et al. 2016: 136). Call was recently described by De Almeida et al. (2014) based on a single male.
