Specimens examined (7).—Krau: TK 152009 (GenBank EU521601), TTU 108211; Monggis: TTU 108240, TK 152091; Mt. Penrisen: TTU 108373, TTU 108378, TTU 108387.

Type locality.— Burma, Tenasserim, Moulmein, Farm Caves .

Malaysian distribution.—Recorded from the lowlands of Peninsular Malaysia (all states) and Borneo.

Remarks.—We netted this species near banana trees. Eonycteris spelaea can be distinguished from their larger counterpart E. major by forearm length and shorter muzzle size (see E. major species account). Like E. major, this species also has an enlarged external gland lateral to the anus. Eonycteris spelaea is distributed throughout most of Southeast Asia and often found in colonies of thousands in caves within agricultural areas (McClure et al. 1967; Heaney et al. 1989). Genetic distance value of <0.8% was observed within Peninsular Malaysia and Borneo individuals, whereas genetic distance value of 1% was observed between Peninsular Malaysia and Borneo individuals. A pregnant female, TK 152085 (8 August 2006), was recorded with an embryo length of 31 mm.
