According to Richard Lydekker, the name rhim is known in Algeria and Libya, while in Tunisian and Egyptian the animal is known as the ghazal abiad, "white gazelle", owing to its pale coat. The name rhim is cognate with and perhaps derived from the Hebrew term re'em found in the Bible, which may refer to an aurochs, oryx or perhaps a unicorn. Although described and named by Frédéric Cuvier in 1842, the rhim gazelle was rediscovered by Edmund Giles Loder later in the same century, hence the synonym Gazella loderi and the common name Loder's gazelle.

The rhim gazelle is known from Algeria, Tunisia, Libya and Egypt. It has also been reported from Niger and Chad, but these sightings seem doubtful and its precise range is unclear. The rhim gazelle is found in isolated pockets across the central Sahara Desert. The extreme heat of this environment limits their feeding to the early morning and evening, and G. leptoceros gains most of its water requirements from dew and plant moisture, relying little on open water sources. The rhim gazelle is a nomadic species, moving across its desert range in search of vegetation, though it does not have a set migratory pattern. Its typical habitat is sand dunes and the depressions between them and other sandy areas, but also rocky areas. Heterothermy in Rhim gazelles results in an increase in body temperature during the heat of the day that reduces the amount of evaporative cooling that gazelles would need to do in order to stay cool. By reducing evaporative cooling, gazelles reduce energy expenditure and conserve body water. During cooler temperatures at night, the stored heat can be released, allowing the gazelles’ body temperature to decrease back to a normal physiological range.
