ORDER—CHIROPTERA
FAMILY—Rhinolophidae

COMMON NAME—Arcuate horseshoe bat.

DISTRIBUTION—Sumatra to New Guinea; throughout the Philippines, possibly excluding the Palawan Faunal Region. Specimens from Biliran (USNM), Camiguin (DMNH), Catanduanes (USNM), Dalupiri (FMNH), Fuga (FMNH), Guimaras (USNM), Leyte (USNM), Luzon [Abra (SMF), Cagayan (PNM), Camarines Sur (FMNH), Isabela (FMNH), Laguna (FMNH), Pampanga (USNM), Rizal (USNM) provinces.], Maripipi (USNM), Masbate (SU), Mindanao [Bukidnon (FMNH), Davao del Sur (FMNH), Maguindanao (FMNH), Zamboanga del Norte (FMNH), Zamboanga del Sur (BMNH) provinces], Mindoro (FMNH), Negros (FMNH), Panay (SU), Polillo (FMNH), Sibutu (DMNH), Sibuyan (FMNH), Siquijor (SU), Tawi-tawi (DMNH).

HABITAT—From lowlands to at least 1050 m, in agricultural lands to primary forest (Heaney et al., 1991, in press; Lepiten 1995; Rickart et al., 1993). Roosting sites sometimes in caves (Sanborn, 1952).

STATUS—Widespread, locally common.

COMMENT—Heaney et al. (1991), Ingle and Heaney (1992), and Rickart et al. (1993) have commented that, on most islands, there appear to be a smaller lowland morph associated with caves in agricultural areas and a larger highland morph associated with primary forest. We have also noted subtle but consistent differences between population on each Pleistocene island. Further systematic studies are needed.

COMMENT ADDED IN 2005––Esselstyn et al. (2004) recorded this species as locally common on Palawan Island. Csorba et al. (2003) tentatively included R. anderseni anderseni in this species. Sedlock (2001) described the echolocation calls of specimens from Laguna Prov., Luzon. Documented in montane and mossy forest from 925-1,950 m elevation in Balbalasang, Kaling Province (Heaney et al, 2004).
