Taxonomy

Species delimitation study based on COI, ITS, and morphological evidence concluded that P. pendulum and P. malayanum were synonymized as junior synonyms of P. melanotum.{{cite journal |last1=Zhang |first1=H |last2=Ning |first2=X |last3=Yu |first3=X |last4=Bu |first4=W |title=Integrative species delimitation based on COI, ITS, and morphological evidence illustrates a unique evolutionary history of the genus Paracercion (Odonata: Coenagrionidae) |journal=PeerJ |date=2021 |volume=9 |page=e11459 |doi=10.7717/peerj.11459 |pmid=34123590 |pmc=8164416 |doi-access=free }}

Description and habitat

It is a medium sized damselfly with deep blue eyes. Its thorax is black on dorsum with very broad azure blue antehumeral stripes, which are very narrow or missing in Paracercion calamorum. Lateral sides of thorax are blue with a fine black line on the upper part of each lateral suture. No pruinescence compared to P. calamorum. Its wings are transparent and pterostigma is yellow, framed with heavy black nervures. Its abdomen is azure blue with broad black dorsal marks up to segment 7. Segment 2 has a distinct broad dorsal spot shaped like a thistle-head connected narrowly to a fine apical ring. This mark will help to distinguish it from Pseudagrion species. Segment 10 has a narrow mid-dorsal black streak. Female is dull green in colors. Its abdomen is similar to the male. But the lateral ground colour is yellowish red and segments 8 and 9 are broadly black on dorsum. Segment 10 is blue only in the apical border.

It breeds in shallow lakes, ponds and paddy fields in the lowland, perches on the floating vegetation.{{cite book|author=C FC Lt.
