Lethribus borbonicus is found in the Western Indian Ocean. It is distributed along the coast of eastern Africa from the gulf of Suez and Gulf of Aqaba south through the Red Sea and south to Sodwana Bay in South Africa. It is found around Madagascar, the Comoro Islands, the Seychelles, the Mascarenes and around the Arabian Peninsula and the Persian Gulf as far east as Pakistan.

This species is found at depths between 1 and 40 m (3 ft 3 in and 131 ft 3 in) in areas of sandy substrates, in the vicinity of reefs, during the day when they may also gather in small groups. At night they are solitary and hunt over reef flats and slopes
