ORIGINAL DATA. — Our recent field surveys did not yield any specimen attributed to this species. FIG. 15. — Macronycteris gigas (Wagner, 1845) . Photo: © Aaron Manga Mongombe. HABITAT AND DISTRIBUTION. — This species is widely distributed over much of West and Central Africa from Sierra Leone in the West, through the Congo Basin to East Africa and the Democratic Republic of the Congo . Nycteris arge is predominantly a lowland rainforest inhabitant, although in southern Africa it can be encountered in forest edges ( Monadjem et al. 2010 ). It roosts singly or in small groups in hollow cavities of trees with large trunks, especially trees with opening near the ground ( Happold 1987 ). According to Rosevear (1965) , this species forages in forest clearing and may enter houses to hunt insects attracted to strong light. This species has been listed to occur on Mount Cameroon ( Van Cakenberghe & De Vree 1985 ).
