In 2001, a paper was published that cited the presence of the small mouse-tailed bat, R. muscatellum, in the Hadramaut Province of Yemen.

The 2007 study concluded that the population discovered in Yemen in 2001 was a distinct clade within R. muscatellum, but the authors stopped short of describing it as a new species.

Its species name hadramauticum is a Neo-Latin derivation of "Hadramaut", which is the place where the holotype was collected.

The skin of its face, ears, belly, and extremities is pale gray in color.

The habitat around the roost, where the bat presumably forages, consists of arid and semi-desert climate.
