Range Description

The Pacific Sheath-tailed bat contains four subspecies:

Emballonura semicaudata rotensis is found on the Marianas, and was historically on Guam, Rota, Aguiguan, Tinian, Saipan. Today it is only present on Aguiguan Island.

E. s. semicaudata was historically found in Samoa, American Samoa, Fiji, Palau, and Tonga. In Samoa, it was found on Savai'i and Upolu, where it was common; in American Samoa, it was found on Manua and Tutuila. This species has now disappeared from Samoa and American Samoa (Tarburton 2002). In Tonga, it was found on Eua and Niuafoou, and was last collected in 1989. In Fiji, it was found on Taveuni, Ovalau, Viti, Levu Lakiba, the Yasawas, and Rotuma (it is common on the last). The species is also known historically from Vanuatu (Koopman 1997).

E. s. sulcata occurs on the islands of Chuuk and Pohnpei in the Caroline Islands, and is doing well on at least Pohnpei. It is not found in the Marshall Islands (there was an erroneous record of presence from there).

E. s. palauensis is found on Palau, including Koror, Peleliu, Babelthuap, and Anguar, where it is common. It ranges from sea level up to 210 m asl (Wiles et al. 1997).
