Pristimantis achuar —New synonymy, Elmer and Cannatella, 2008, Zootaxa, 1784: 13. Holotype: QCAZ 25463, by original designation. Type locality: "Kapawi Jungle Lodge, Pastaza province, Ecuador ( S 02° 32.32 ′, W 76 ° 51.50 ′, altitude 239 m)".

Remarks. A list of diagnostic characters, character variation, distribution and comparison with similar species in the Amazon basin for Pristimantis luscombei are provided by Elmer and Cannatella ( 2008) as P. achuar . Overall, P. luscombei is most similar to P. kichwarum , but is clearly distinguished form the latter by lacking a dark canthal stripe and by a blunter snout. Moreover, P. luscombei is slightly smaller in size ( Elmer & Cannatella 2008). This species is known from several localities along the upper Amazon Basin in Morona Santiago and Pastaza provinces in Ecuador ( 17 localities), and Amazonas and Loreto Departments in Peru ( 28 localities). Except for the record of this species in Distrito Río Santiago, Quebrada Kampankis ( CORBIDI 11393, S 4.04308, W 77.54119, 1212 m a.s.l.), all localities correspond to lowland evergreen forest at elevations between 100 and 800 m a.s.l ( Fig. 4 ). This area covers 437,500 km 2 along the northern part of the upper Amazon Basin. Lynch ( 1980 b) reported this species as P. ockendeni morph B ( Elmer & Cannatella 2008), from a series collected by B. Malkin at Cusime, Río Cusime, Morona Santiago province, southeastern Ecuador. We reviewed specimens studied by Lynch ( 1980 b) and additional material collected in a nearby locality from Ashuara village on río Macuma, Morona Santiago province.

Among the 64 specimens studied, 74 % correspond to P. luscombei , whereas the rest are P. ki c hw ar u m (Appendix III). Furthermore, López-Rojas et al. ( 2013) reported P. luscombei (as P. achuar ) for western Brazil.
