Apomys littoralis Sanborn 1952

Apomys littoralis Sanborn 1952, Fieldiana Zool., 33 (2): 134.

Type Locality: Philippines, Mindanao Isl, Bugasan, Cotabato, 50 ft (15 m).

Vernacular Names: Mindanao Lowland Apomys.

Distribution: Endemic to the Greater Mindanao Faunal Region on islands of Biliran, Bohol, Leyte, and Mindanao (Musser and Heaney, 1992; Rickart et al., 1993; Heaney et al., 1998). Formerly recorded from Negros (Musser, 1982 b), but that sample represents an undescribed species (Heaney et al., 1998).

Conservation: IUCN – Lower Risk (lc).

Discussion: Included within Apomys abrae hylocetes Group by Musser (1982 b). This species is known by a juvenile holotype with damaged skull from Mindanao and several referred series from Leyte and nearby smaller islands (Heaney et al., 1998). Distributional and ecological data provided by Rickart et al. (1993). The standard karyotype reported for a sample from Leyte (2n = 44, FN = 88; Rickart and Musser, 1993), which expresses the highest FN recorded for Indoaustralian murines, actually comes from an undescribed species (Rickart and Heaney, 2002; Steppan et al., 2003).
