Here, I describe the wing sac morphology of five species of Emballonuridae, namely Saccopteryx bilineata, Saccopteryx leptura, Balantiopteryx plicata, Peropteryx macrotis, and Cormura brevirostris, and discuss possible phylogenetic relationships and origins. 

Figure 1. Dorsal view of a wing sac from a male Saccopteryx bilineata. The thorax of the bat is at the left side of the picture and the wing is fiilly extended.

Perfume-blending behaviour has not been observed in any other emballonurid species as yet. However, as (1) histological examinations indicate the absence of glandular tissue in the wing sac also in other species and as (2) odoriferous liquids are present at least in some of these species, it is very likely that other emballonurid bats perform a behaviour similar to that of Saccopteryx bilineata.
