Range DescriptionIts range is unknown but probably extends south along the left bank of the Rio Roosevelt and at least part way north to meet, somewhere, the southern limits of the range of M. manicorensis. Ferrari (1993, 1994) reported the collection of an adult female “C. emiliae” on the east bank of the Rio dos Marmelos opposite the Tenharin Indian settlement (on the west bank, 07º57'S, 62º03'W). (For the correct location of Tenharin, see Ferrari 1994). Ferrari (1993) said it was easily distinguished from M. nigriceps (collected on the west bank at the same location) by the lack of pigmentation on the facial skin. It would seem that Ferrari (1993) presumed the identity of this animal to be C. emiliae based on Vivo (1985, 1991) who stated that C. emiliae occurred on the left (west) bank of the Rio Aripuanã: a belief arising from his interpretation of the identity of the marmoset of the Rio Castanho, here listed as Mico marcai (Alperin 1993). However, the true identity of the marmoset from the east bank of the Rio dos Marmelos at Tenharin has yet to be determined in light of this.
Van Roosmalen et al. (2000) inadvertently indicated that Mico manicorensis occurred at the type locality of this species.
