18. Myotis horsfieldii Temminck, 1840 Horsfield’s Myotis New records Middle Andaman Islands: Bamboo Nullah, Baratang Island, Devpur and Nayadera; Little Andaman Island: V.K. Pur. Previous records Middle Andaman Islands: Webi (HZM); South Andaman Islands: Port Blair (Andersen, 1907; Hill, 1967). Comments The Andaman Island endemic subspecies is M. horsfieldii dryas Andersen, 1907. Out of the 15 individuals captured, eight specimens were collect- ed. Aul et al. (2014) reported the presence of this species from Point Island, Paget Island, North Reef Island, and Smith Island in North Andaman Islands; Interview Island in Middle Andaman Islands, and Little Andaman Island. The endemic subspecies varies from the mainland subspecies, M. h. peshwa, in its bacular morphology. Echolocation Characteristics A total of 556 calls were analysed from 12 species of echolocating bats (including a new phonotype of Hipposideros cf. pomona) from the Andaman Islands. Of these, 378 calls from seven species (R. andamanensis, R. cognatus, H. pomona, M. spasma, P. javanicus camortae, P. coromandra, and M. horsfieldii dryas) were analysed in Bat- Sound, and 187 calls from six species (H. cf. pomona, H. diadema masoni, H. cf. grandis, T. melanopogon, H. tickelli, and T. robustula) were analysed in AnalookW. Of all the calls analysed in BatSound, 100% of FM calls (Overall, Wilk’s λ = 0.001, P <0.001) and 100% of CF calls (Overall, Wilk’s λ = 0.002, P <0.001), and of all the calls analysed in AnalookW, 99% of FM calls (Overall, Wilk’s λ = 0.024, P <0.001) and 100% of CF calls (Overall, Wilk’s λ = 0.006, P <0.001) were accurately attributed to their respective species (Table 4).
