CYCLOPES THOMASI SP. NOV.

( FIG. 20)

Holotype: Female, MZUSP (19944). Collected by Dr Paulo Emílio Vanzolini in 1985 ( Figs 21, 26).

Type locality: Porto Walter, Acre, Brazil.

Referred specimens: Holotype: MZUSP (19944) Porto Walter , Acre, Brazil ; Brazil: INPA (2876), Igarapé Porongaba, Acre; INPA (2877), Seringal Petropolis,

Acre; MVZ (190355), Rio Juruá, Amazonas; Peru: USNM (364503), Pasco.

Etymology: The specific name honours Michael Rogers Oldfield Thomas, in recognition of his extensive contribution to mammalogy, and specifically to the taxonomy of Cyclopes .

Distribution: Cyclopes thomasi occurs in western Amazon, from the north limit on the Juruá River to the southwest, in the Ucayali River region, in the provinces of Pasco and Ucayali ( Peru). The western limits are unknown, but may not extend beyond the Madera River ( Fig. 27).

Diagnosis: Body colour strikingly orange to reddish-brown, legs and tail grey. Dorsal stripe absent. Ventral stripe little developed and faint. Fronto-nasal region of the skull not depressed, with a straight profile. External aperture of the ear directed anteriorly. Naso-maxillary sutures divergent proximally, with a very short fronto-maxillary suture. Fronto-parietal suture with triangular shape, pterygoid bone does not overlap tympanic bulla.

Comparisons: The only other species of Cyclopes with a ventral stripe and no dorsal stripe is C. catellus , which, however, has a very marked and distinct ventral stripe and no greyish tone on the limbs and tail.
