Studies on Odonata have gained worldwide attention as well as locally in Malaysia. Although there is a wealth of data available to be utilized for solving taxonomic problems but ecological and behavioural research areas are more favoured in contrast to taxonomy and systematics. Thus, there are existing confusions for correct identifications in closely related and sympatric species, especially in female odonates. One such example is in the genus of Rhinocypha. Consequently, the research is focused on taxonomic work, employing multi-approaches in the form of morphological (morphological diagnostics, Field Emission Scanning Electron Microscope and geometric morphometric analysis), with applying the molecular technique. 17 morphological characteristics were created to differentiate between the females of Rhinocypha spp. The FESEM on the female’s ovipositor was done to focus on the anal appendages and sheathing valve (V3). Also, the phylogenetic patterns expressed by COI and 16S rRNA genes, and canonical variate analysis for the wing geometric morphometric revealed three clusters that supported the distinction of the Rhinocypha group. In summary, this study had effectively developed an integrated approach of classic morphological and trendy molecular, combined with microscopy techniques, FESEM, which provided corroborative evidence in resolving taxonomic uncertainties.

Key words: Dragonflies, Female’s ovipositor, Geometric morphometric, Mitochondrial COI, 16S rRNA.
