For those interested in sengis, the 2014 paper describing Macroscelides micus is in open access. It has some useful discussion on sengi systematics. Note that IUCN still lists Macroscelides as monotypic, although there are now three species.
In 2008 I drove just a few miles from M. micus range… but looks like the new species is not particularly common and seeing it would require more than passing effort. On the other hand, this is an absolutely delightful part of Namibia and spending some time there would be really enjoyable.
