Hipposideros diadema E. Geoffroy, 1813 Diadem Roundleaf Bat New record Middle Andaman Islands: Baratang Island. Previous records None. Comments First record for Andaman Islands ( Srinivasulu et al. , 2016 ). A single adult female specimen was collected. The specimen is distinctly larger than H. diadema nicobarensis recorded from the Nicobar group of Islands. It showed characters similar to that of the taxon masoni , namely the presence of a small conical bony process from the symphysis of the mandible and the presence of a single median vertical septum forming a small projection above the margin of the fleshy posterior leaf of the noseleaf, dividing the posterior leaf into two large cells, and hence has been listed as H. d. masoni Dobson, 1872 . This specimen is also slightly larger than the taxon masoni recorded from Myanmar and the Sunda Islands (see Srinivasulu et al. , 2016 ).
