Subspecies Aotus azarae subsp. boliviensis Elliot 1907

Distribution: Bolivia south of Amazon, between Rios Tocantins and Tapajos-Juruena, south to Paraguay and N Argentina.

Conservation: CITES – Appendix II; IUCN – Lower Risk (lc).

Discussion: Red-necked species group. Pieczarka and Nagamuchi (1988) proposed that infulatus may be conspecific with A. azarae; followed by Ford (1994) and Groves (2001 c). Groves (1993) changed the form of the name to azarai in accordance with Art. 31 of the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature, 1985 d), but D. Brandon-Jones (pers. comm.) pointed out that Art. 31.1.3 recommends that the original spelling be preserved.
