Data and maps were assembled by Galen Rathbun (see “site info” on home page for contact information to ask permission to use data). Sengi locations (total = 2366) were gathered using museums, literature, and personal communications, as cited for the 2009 maps. Accuracy of species identification was not verified for many sources, and the precision of older locations (pre-GPS receivers) is to centroids of the quarter degree grid square system, or sometimes district. Locations with a “?” indicate especially questionable species identification or location data.  The distribution polygon for each taxon was constructed subjectively, encompassing the outer-most locations, but sometimes avoiding obviously unsuitable habitats, or including those that are likely suitable. However, many sengi species are habitat specialists and the generalized polygons are over-simplified, especially for those with highly fragmented habitats, such as the giant sengis (Rhynchocyon).  Some isolated records have not been incorporated into a polygon because of the obvious gap in habitat.  Click on any data point for the database reference number and museum catalog number, if available.  Museum abbreviations, click here. With maps appearing on Google Earth software, click on any data point for the database reference number and museum catalog number, if available.
