Saguinus mystax (Spix, 1823)

VOUCHER MATERIAL (TOTAL 5 35): Marupa (AMNH 98288, 98289), Nuevo San Juan (AMNH 268237; MUSM 11105, 11106, 13303), Orosa (AMNH 73741, 73743–73745, 73747, 73750, 73985, 74039, 74044, 74047, 74049, 74050, 74052), Quebrada Esperanza (FMNH 88870–88872), Santa Cecilia (FMNH 86951–86957, 86959–86962, 87138– 87140).

UNVOUCHERED OBSERVATIONS: Actiamë ( Amanzo, 2006), Choncó ( Amanzo, 2006), Itia Tëbu ( Amanzo, 2006), Jenaro Herrera ( Aquino, 1978), Reserva Comunal Tamshiyacu-Tahuayo ( Puertas and Bodmer, 1993; Heymann and Aquino, 1994), Río Aucayo ( Castro and Soini, 1977), Río Yavarí (left bank below Angamos; Salovaara et al., 2003), Río Yavarí-Mirím ( Salovaara et al., 2003), Tapiche ( Jorge and Velazco, 2006).

IDENTIFICATION: Hershkovitz (1977) examined the series from Marupa, Orosa, Quebrada Esperanza, and Santa Cecilia for his taxonomic revision of Saguinus , wherein this material was referred to S. mystax mystax . Our material from Nuevo San Juan is indistinguishable from that examined by Hershkovitz, conforming to his diagnosis of the nominotypical race by lacking both the reddish coronal fur of S. m. pileatus (listed as a distinct species by Groves, 2001, 2005) and the whitish ventral tail base of S. m. pluto. Craniodental measurements from representative specimens are summarized in table 9. Most moustached tamarin specimens from the Yavarí-Ucayali interfluve are unaccompanied by weights, but an adult male ( AMNH 268237) from Nuevo San Juan weighed 522 g, another ( MUSM 13303) weighed 585 g, and an adult female from the same locality weighed 650 g.
