FIG. 1 in Geographical variation of Rhinolophus affinis (Chiroptera: Rhinolophidae) in the Sundaic subregion of Southeast Asia, including the Malay Peninsula, Borneo and Sumatra

FIG. 1. Sample localities and echolocation frequencies of R. affinis in the Sundaic subregion. M = Peninsular Malaysia, Sa = Sarawak, S = Sumatra, and T = Thailand. Abbreviations for localities are given in the methods and materials. The grey shading indicates the Sundaic biogeographic subregion following Woodruff (2010), green (zone A) and orange (B) shadings are the echolocation zones recognized in the Malay Peninsula. Dashed arrows indicate type localities and subspecies names, solid arrows indicate the transition zone of biota within the Malay Peninsula, dashed lines indicate the echolocation frequencies (min–max), and the two-headed arrows indicate the echolocation frequencies (min–max) as a whole from each echolocation zone. Note: the northern boundary of the Sundaic subregion is sometimes placed at the Isthmus of Kra (e.g., Lekagul and McNeely, 1988 and Corbet and Hill, 1992)
