|Scientific Name:||Cheirogaleus crossleyi|
|Species Authority:||A. Grandidier, 1870|
Cheirogaleus melanotis Forsyth Major, 1894

|Reviewer/s:||Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)|
Listed as Data Deficient as the species is very poorly known, and there is very limited information available on its distribution or population size. However, given likely threats, the species may warrant listing as threatened in future.
|Range Description:||This species is endemic to the island of Madagascar. As with other species formerly included in C. major and regarded as distinct, the range of C. crossleyi remains to be determined. Groves (2000, 2001) describes it as running inland to that of C. major in eastern Madagascar and extending farther to the north, this based on specimens from Lac Alaotra, Andasibe, and Vohémar. According to Hapke et al. (2005), this is also one of three Cheirogaleus species found west of Tolagnaro, along with C. major and C. medius.|

|Population:||Unknown, and complicated by taxonomic confusion with allied forms of Cheirogaleus in the eastern rainforests. In the Andasibe-Mantadia National Park, Cheirogaleus now thought to be this species were recorded at densities of 70-110 individuals/km² (Pollock 1979).|
|Habitat and Ecology:||Inhabits the eastern moist forests, but other information on ecology and behaviour is complicated by taxonomic confusion with allied forms of Cheirogaleus in the eastern rainforests.|
|Major Threat(s):||Unknown, but habitat loss is a likely threat across the range.|
|Conservation Actions:||This species is listed on Appendix I of CITES. It could be present in at least two national parks, Mantadia and Zahamena, and in the Zahamena Strict Nature Reserve, although this may require confirmation given the taxonomic uncertainty surrounding the exact distributional limits of the various species of Cheirogaleus in the eastern rainforests. It may also be the form in Analamazaotra Special Reserve (Mittermeier et al. 2008). Taxonomic work is urgently required to elucidate more clearly the taxonomic and geographic limits of the species.|
