Systematic review of the firefly genus Emeia Fu, Ballantyne & Lambkin, 2012 (Coleoptera: Lampyridae) from China

The Luciolinae genus Emeia Fu, Ballantyne & Lambkin, 2012 is reviewed. Firefly species tree is reconstructed based upon phylogenetic analysis of CO1 barcoding sequences from 42 fireflies and 2 outgroup species, including three main Lampyridae sub-families: Luciolinae, Photurinae and Lampyrinae. The genus Emeia belongs to Luciolinae based on morphological and DNA sequence level evidences, the diagnostic features for male adults include pink-red pronotum with a black median stripe, subparallel-sided pronotum, un-developed elytral humeral carina. In this study, a new Emeia species,Emeia pulchra sp. nov. is described and illustrated from the wetland of Lishui, Zhejiang, China. The new species is sister to E. pseudosauteri in the Emeia genus which is supported by characteristic morphological features and DNA barcoding data. The two species are separated geographically as shown on the distribution map. A key to the males of the species of Emeia is also provided.
