摘要
The taxon Rhinolophus microglobosus is elevated to specific rank on the basis of clearly defined morphometric and acoustic characters which differentiate it from Rhinolophus stheno. It is recorded from Cambodia for the first time. Rhinolophus malayanus exhibits considerable geographical variation in echolocation calls, with apparently two phonic types: a northern population with lower frequency calls and a predominantly southern population with higher frequencies. However, this acoustic divergence is not reflected in any morphometric divergence, and the taxonomic status of the two phonic populations remains unclear. Discriminating characters of all three species are given, together with distribution data and short ecological summaries. The value of echolocation as an indicator of cryptic species and the zoogeographical implications of the study are briefly discussed.
