Echolocation: Consistent with published data for M. spasma in Vietnam (Furey et al. 2009; Győrössy et al. 2024 a), our bats emitted short, broadband, frequency-modulated (FM) calls with multiple harmonics (lowest frequency of the second harmonic: 37 – 40 kHz) (Appendix 4).

Morphology: The external characters and measurements of our specimens (FA: 54.5 ± 1.8 mm (52.5 – 56.1 mm), TIB: 31.6 ± 0.4 mm (31.3 – 32.0 mm) agree with published data for Megaderma spasma (52 – 62 mm: Kruskop 2013). Members of the Megadermatidae are easily distinguished from all other bats by their short and convex-sided vertical noseleaf, large ears joined (to differing extents), and a long bifid tragus. Megadema spasma differs from the closely related Lyroderma sinensis by its smaller size (FA: 54.5 ± 1.8 mm vs 68.4 mm), shorter vertical noseleaf with a rounded apex and distinctly convex sides, median ridges with wide heart-shaped base, and fusin of inner margins of ears fused at about 15 % or less of their height (Figure 2 A). Genetics: No sequences were generated for this species, as morphological identification was considered reliable and prior evidence indicates low genetic structure across Southeast Asia (e. g., Feng et al. 2025; Soisook et al. 2015).
