Rio Manicore Marmoset (Callithrix manicorensis)

MORPHOLOGY:
The Rio Manicore marmoset has nails on the digits that are more claw-like. This species also has nonopposable thumbs. This species has a pelage color that is overall white on the ventral side and white, transversely mottled with gray on the dorsal side (van Roosmalen et al., 2000). The back and the rump are grayish white mottled darker gray giving a transversely stripes appearance (van Roosmalen et al., 2000). The belly of this species is orange in color (van Roosmalen et al., 2000). The dorsal surface of the lower arms is slightly orange and the ventral surface is ochraceous to orange in color (van Roosmalen et al., 2000). The ventral surfaces of the legs are orange and the tail is black with the proximal end slightly mottled orange and gray in this species (van Roosmalen et al., 2000). This species has a naked face that is orange with dark brown around the eyes and on the lower lip and chin (van Roosmalen et al., 2000). The nostrils and circumbuccal area is pink to flesh-colored, mottled dark brown, with the nostrils also having a dark brown stripe (van Roosmalen et al., 2000). The iris is dark brown in color (van Roosmalen et al., 2000). The genitals of the Rio Manicore marmoset are non-pigmented (van Roosmalen et al., 2000).

RANGE:
This species is found in the country of Brazil. The Rio Manicore marmoset is found on the west bank of the lower Rio Aripuana to the east bank of the Rio Madeira to the mouth of the Rio Aripuana and south to the headwaters of the Rio Manicore (van Roosmalen et al., 2000). This species lives primary terra firme forest and in secondary forests surrounding fields and plantations (van Roosmalen et al., 2000). This species is also found in the seringal forest which is a managed forest used to grow commercially valuable and edible fruit such as rubber, Hevea brasiliensis, Brazil nut, Bertholletia excelsa, and wild cocoa, Theobroma sp. (van Roosmalen et al., 2000).
