However, despite the large amount of biodiversity within the Taita Hills, no surveys of bushbabies have ever been undertaken, so for a long time, the actual presence of the Uluguru bushbaby within this mountain range was unknown. However, as time passed and more species of bushbaby were discovered and made their own taxon (Largely due to extensive research into their vocalisations, reproductive anatomy and genetics), as well as the fact that the presence of the Uluguru bushbaby was already known around some parts of Tanzania (Particularly at other parts of the Eastern Arc Mountains, which the Taita Hills, along with Mount Sagala and Mount Kasigau, make up the north-easternmost part of, their presence had been realised, along with two other species of bushbaby (Paragalago rondoensis and Paragalago udzungwensis). It is possible that these observations may be of a new subspecies of the Uluguru bushbaby, being names the Taita dwarf mountain galago, however this has not been formally identified.
