Abstract

The taxonomy of Hipposideros galeritus remain unresolved as it does not clearly define evolutionary relationships boundaries between species of the same genus. Previous molecular phylogenetic studies revealed the instances of paraphyly and deep genetic divergence within currently recognised H. galeritus lineage indicating diversity within this species is underrepresented with current nomenclature. Hence, this study aims to resolve the taxonomy of H. galeritus complex using cytochrome c oxidase I gene (COi), morphometric and echolocation call data. The significant genetic variation (2.9 - 18.4 %), indicates possible different subspecies and distinct genetic species. Sabah and Northern Sarawak clade suggest to be H. labuanensis, Malay Peninsula as H. galeritus galeritus while high genetic distance and distinct monophyletic clades; Indochina and Southern Sarawak with Niah highly suggest new species nomenclature which is currently unrecognized. Potential subspecies is also seen to occur within same biogeographic region supported with notable genetic distances. Morphometric data analysed as OF A in SPSS shows DBC as the best resolving character. Echolocation calls were analysed with Kaleidoscope and OF A. The variables of FMaxE and FMEAN had significant difference between Sarawak populations but not able to classify populations. There is no relationship between forearm length and peak frequency in this study. More representative samples should be included from biogeographic regions (apart from Sarawak) to have a full understanding of H. galeritus taxonomy. A more vigorous documentation of echolocation and morphometric data will be helpful to have a complete description of H. galeritus taxonomy.
