Bunomys andrewsi J. A. Allen 1911

Bunomys andrewsi J. A. Allen 1911, Bull. Am. Mus . Nat. Hist., 30: 366.

Type Locality: Indonesia, NE Sulawesi, Buton Isl.

Vernacular Names: Andrew's Bunomys.

Synonyms: Bunomys adspersus (Miller and Hollister 1921); Bunomys heinrichi (Tate and Archbold 1935); Bunomys inferior (Tate and Archbold 1935) .

Distribution: Sulawesi; central core, SE and SW peninsulas; primarily found in lowland tropical evergreen rainforest but reaches lower montane rainforest in some places.

Conservation: IUCN – Lower Risk (nt) as B. heinrichi, otherwise Lower Risk (lc).

Discussion: Bunomys fratrorum Group. Recognized as a distinct species in a " Rattus chrysocomus Group" (Tate, 1936; Ellerman, 1941), then in a " coelestis group" of Rattus (Ellerman, 1949 a), subsequently treated as member of subgenus Rattus (Laurie and Hill, 1954), and currently included in Bunomys (Musser, 1981 c; Musser and Newcomb, 1983). In morphology and pelage features, B. andrewsi is most closely related to B. fratrorum of the NW peninsula and B. penitus in the central core and SE peninsula. The taxon heinrichi has been treated as a species (Musser, 1991; Musser and Holden, 1991; Musser and Carleton, 1993), although originally described as a subspecies of Rattus penitus and listed that way by Ellerman in 1941; later arranged as a subspecies of Rattus adspersus (Ellerman, 1949 a; Laurie and Hill, 1954), or included within Bunomys penitus (Musser, 1981 c; Musser and Newcomb, 1983) or Frateromys penitus (Sody, 1941) . Karyotype summarized by Rickart and Musser (1993). Considerable geographic variation in craniodental measurements typifies B. andrewsi, but its significance will have to be determined by study of larger samples from more localities than are currently available.
