Conservation status There were 35 collections representing 25 localities available for analysis, which resulted in an Extent of Occurrence (EOO) of 61,385 km 2 and an Area of Occupancy (AOO) of 84 km 2 that is certainly much larger given the presence of uncollected areas of suitable habitat. Sixteen subpopulations representing 13 locations were estimated, of which six occur within the network of protected areas (Ankarafantsika, Beanka, Bemaraha, Corridor Bongolava, Menabe-Antanimena, and Namoroka). Therefore, N. alleizettei is assigned a preliminary status of “ Least Concern ”.
