“…Therefore, these three species may have originated from one widely distributed ancestral species. Dumont (2004) and Ning et al (2016) also suggested that P. sieboldii shared a common ancestor with the continental P. v-nigrum .…”

“…Specimens were examined and dissected under a Zeiss V8 stereomicroscope. More than 600 specimens (including dried specimens) were identified by Xin Yu and Xin Ning in terms of the corresponding literatures ( Dumont, 2004 ; Yu, 2008 ; Yu & Bu, 2011 ; Ning et al, 2016 ). All the specimens were stored at the College of Life Sciences, Chongqing Normal University.…”

“… Yu & Bu (2011) combined Coenagrion dorothea Fraser, 1924 as Paracercion dorothea (Fraser, 1924) and confirmed that Paracercion impar (Needham, 1930), one of the eight species described in Dumont (2004) , was a junior synonym of P. dorothea . Ning et al (2016) described a new species Paracercion ambiguum Kompier & Yu, 2016 from Vietnam based on molecular and morphological characters. Twelve species are recorded in the genus Paracercion globally ( Schorr & Paulson, 2020 ).…”

Paracercion are common ‘blue and black’ colored damselflies. We explore the species boundaries of Paracercion (Odonata: Coenagrionidae) using ABGD, bPTP, GMYC and Distance-based clustering. We finally got the molecular data of all nine species of Paracercion. P. hieroglyphicum and P. melanotum were combined into one putative species based on cytochrome c oxidase I (COI). However, they were separated into two putative species based on the nuclear segment including ITS1-5.8S-ITS2 (ITS). This suggests the introgression of mtDNA in Paracercion. Paracercion barbatum and Paracercion melanotum can be separated into two species based on COI, whereas they were combined into one putative species based on ITS, which suggests a hybridization event between them. The lower interspecific divergence (COI: 0.49%) between P. barbatum and Paracercion v-nigrum indicates a recent speciation event in Paracercion. Paracercion sieboldii and P. v-nigrum can be separated into two putative species based on COI, while they were frequently merged into the same putative species based on ITS. This can be explained by incomplete lineage sorting in nDNA. Besides, P. pendulum and P. malayanum were synonymized as junior synonyms of P. melanotum. P. luzonicum was confirmed not to belong to Paracercion. The possibility of introgression, hybridization, recent speciation and incomplete lineage sorting makes species delimitation, based on molecular data, difficult and complicates understanding of the evolutionary history of Paracercion. The discordance in COI and ITS also indicates the value of using markers from different sources in species delimitation studies.

Taxonomically, identification of complex taxa based on external morphological characters may leads to wrong identification of unknown organism at species level because these characters may also be altered due to geographical and seasonal variations. To overcome this molecular taxonomy has been emerged. In India, out of 9 morphologically described species of genus Ischnura (Odonata: Coenagrionidae), Ischnura senegalensis is the only species, which has been barcoded on the basis of COI gene. During the present study, mitochondrial COI gene has been barcoded for four species of genus Ischnura (Ischnura aurora, Ischnura forcipata, Ischnura rufostigma and Ischnura senegalensis), collected from fresh water bodies from the states of Punjab and Himachal Pradesh (India). Across the final alignment of COI sequences of 352bp, there are 282 conserved sites (80.1%), which represents that COI gene is highly conserved. Conspecific species show <1% divergence range (0% to 0.6%) and interspecific divergence ranges from 7.5% to 15.6%. COI gene sequences of all the species shows 95 – 100% similarity with the sequences of conspecific species deposited in GeneBank. Mitochondrial COI gene based DNA barcoding has been done for Ischnura aurora, Ischnura forcipata and Ischnura rufostigma for the first time from India and for Ischnura forcipata throughout the world.

More than 800 specimens of Chinese Ceriagrion were studied, almost a quarter were used for molecular analysis. Methods of cladistics, ABGD, jMOTU, bPTP, as well as morphology, were used for species delimitation. Nine species were identified and confirmed occurring in China. A taxonomic key of males was given. Two new synonyms (Ceriagrion chaoi to Ceriagrion bellona, Ceriagrion olivaceum to Ceriagrion azureum) were proposed, Ceriagrion malaisei was confirmed new to China, the distribution of Ceriagrion rubiae in China was eliminated, and three incorrect identifications were corrected.
