Abstract

In this study, the Laena species from northern Sichuan Province were reviewed using a combination of molecular and morphological datasets. Three molecular methods for species delimitation were firstly used in the genus Laena to explore species boundaries. The results show that the number of morphospecies and putative species using Automatic Barcode Gap Discovery (ABGD) is consistent. Based on the results, two new species are described and illustrated: Laena mounigouicasp. nov. and Laena dentithoraxasp. nov. New materials and distribution of 10 Laena species are also provided in this study. This work also provides valuable molecular data for species identification and phylogenetic analyses of the genus Laena and subfamily Lagriinae.
