Taxonomic note Bats morphologically resembling H. larvatus from Lao PDR include at least three distinct species differing in genetics, morphology and echolocation calls. Thabah et al . (2006) also noted that multiple species occur in the region, but further study is needed to determine which, if any of the populations they distinguished match those found in Lao PDR. Some authors (e.g., Simmons, 2006) have used the name H. grandis for some mainland populations, but the type specimen has not been examined to confirm if that is an appropriate name for any of the Lao forms.
