Tupaia moellendorffi Matschie 1898 Tupaia moellendorffi Matschie 1898, Sitzb. Ges. Naturf. Fr. Berlin: 39. Type Locality: Philippines, Culion Isl. Vernacular Names: Calamian Treeshrew. Subspecies:: Subspecies Tupaia moellendorffi subsp. moellendorffi Matschie 1898 Subspecies Tupaia moellendorffi subsp. busuangae Sanborn 1952 Subspecies Tupaia moellendorffi subsp. cuyonis Miller 1910 Distribution: Calamian Isls (Busuanga, Culion) and Cuyo in the Philippines. Conservation: CITES – Appendix II; IUCN – Vulnerable (as included in T. palawanensis). Discussion: The three named forms included here appear more closely-related to each another than any is to T. palawanensis (where they are usually arranged; e.g. Heaney et al., 1998) and I provisionally separate them here as a distinctive complex; see also comments by Lyon (1913). This arrangement is somewhat more consistent with species-boundaries traditionally recognized in squirrels from the Palawan region (see accounts of Sundasciurus).
