Allobates sp.

Allobates sp. is a species with smaller body size (maximum SVL = 17.8 mm) compared to the two sympatric large-sized Allobates Zimmermann & Zimmermann, 1988 ( A. femoralis – Fig. 4A – and Allobates vanzolinius [ Morales, 2002], with minimum SVL = 19.6 mm), also differing by its cryptic coloration (vs. brightly colored in A. femoralis ), and cream-colored throat in males, in some specimens punctuated with small black dots (vs. uniformly dark throat in males of A. vanzolinius ). Some of these specimens could correspond to Allobates gasconi ( Morales, 2002) , as INPA-H 004986 is a paratype of this species. However, we opt to maintain a conservative taxonomic status, due to the combination of overall uncertainty in attributing taxonomic status of cryptically colored Allobates , historical composite type series (MeloSampaio et al., 2018), and the fact that Juruá River basin harbor many morphologically similar small-bodied species. We also cannot safely discard the occurrence of more than one species contained under this taxon.
