Integrative species delimitation based on COI, ITS, and morphological evidence illustrates a unique evolutionary history of the genus Paracercion (Odonata: Coenagrionidae).

ABSTRACT: 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 betwe
