have been collected from Amazonia. The genus appears to be either difficult to trap or generally uncommon, although exceptionally high numbers have been collected at some localities (e.g., the PDBFF reserves north of Manaus; Malcolm, 1991b). The scattered number of localities, and the general lack of adequate series even from those sites where specimens are known, has stifled interest in the systematics of this group. Christopher Tribe’s (1996) recent revision represents a quantum leap beyond our existing understanding of the systematics of

is a broadly ranging genus and species exhibit considerable differentiation in body size and both external and craniodental characters. However, this large group of species can be distinguished from other sympatric murids, and specifically those of the Rio Juruá basin, by a tail that is much longer than head and body, and typically terminated by a relatively long tuft of hairs; short and very broad feet with proportionately long toes and with pale sides but darker dorsal patch over the metatarsals; and six mammae in females. Cranially (fig. 107) these taxa are readily recognizable by a combination of very shallow zygomatic notches a narrow zygomatic plate with a vertical anterior edge and no anterior projecting spine moderate supraorbital ledges that extend divergently onto the sides of the cranium as parietal ridges; a short and broad palate with the incisive foramina extending to the level of the anterior root of first molar, the mesopterygoid fossa extending to the posterior margin of the third molar, and no large posterolateral palatal pits; no or only minute sphenopalatine vacuities; a robust alisphenoid strut; small bullae with the tegmen tympani overlapping the posterior suspensory process of the squamosal; nonsulcate upper incisors; and molars cuspidate, brachydont and pentalophodont with cusps (ids) opposite rather than alternate. The cephalic arterial pattern may either be derived (pattern 3 of Voss, 1988; Carleton and Musser, 1989) with a minute stapedial foramen, no squamosalalisphenoid groove, and no sphenofrontal foramen, or primitive (pattern 1).

The two also differ in karyotype (see below) and in sequence data from the cytochromeb gene.
