Haplotypes for specimens from the Rio Juruá are identified by heavy lines and bold type; numbers refer to the specific locality as identified in the text and the map, fig. 1. Bold numbers at internal nodes are bootstrap values, based on 1000 iterations; percentages are average Kimura twoparameter distances. Data are given only for nodes with bootstrap values> 50. Tree length = 530 steps; CI = 0.545; RI = 0.669.

. The skull is delicate, with large anterior and posterior palatal vacuities (fig. 45), and the interorbital region bears supraorbital ledges that are only weakly evident in young animals but become increasingly apparent in olderage individuals. In the oldest animals, these ledges are weakly Vshaped, more so than in any other species from the Rio Juruá (fig. 46). The anterior opening of the infraorbital foramen lies dorsal to the anterior root of PM4. The maxillary toothrow averages 13.5 mm; upper M1M4 molar series length averages 6.7 mm. The canine appears proportionately long and narrow, with its width at the base about 55% its length in unworn specimens.

differs in its brighter dorsal coloration and broader white ventral area with narrower and less obvious lateral bands of graybased hairs (fig. 41). It has less swollen paroccipital processes, more swollen mastoid processes, somewhat more welldeveloped supraorbital ledges (fig. 46), and somewhat longer and narrower upper canines. All palatal vacuities are larger with the posterior ones placed more distally on the palate (fig 45). The two also differ in those qualitative features noted by Gardner (1989), but cannot be distinguished from each other on the basis of external or cranial dimensions (tables 8 9).
