Common English name: Dayak Roundleaf Bat

Barcode Index Number: BOLD: AAD 0486 (1 DNA barcode is from Peninsular Malaysia; Fig 4)

Remarks: Murray et al. [125] found little divergence in ND2 and RAG1 mtDNA (<1%) between “ dyacorum ” in Peninsular Malaysia and East Malaysia, Borneo. However, our NJ analysis showed> 2% divergence between DNA barcodes from Peninsular Malaysia and Sabah, Borneo (Fig 4). We tentatively retained the name H. dyacorum in our checklist pending further research into these taxa.
