[Objectives] To evaluate the performance of three species identification algorithms (jMOTU, ABGD, GMYC) with respect to the Notodontidae (Insecta, Lepidoptera). [Methods] COⅠ genes from 483 notodontid moth specimens collected from 10 collection sites in Northern China around Beijing were amplified using universal barcoding primers. [Results] Results obtained using each of the three algorithims differed. Using the results obtained by morphological species identification methods as a reference, the ABGD algorithm was 100% accurate. The results obtained using GMYC_BEAST were also generally consistent with those obtained by morphological methods, having a confidence interval of 64-68 c.f. 67 species identified by morphological methods. However, the GMYC_d8tree/MPLtree method tended to overestimate MOTUs and the jMOTU method tended to underestimate the number of species. [Conclusion] ABGD and GMYC_BEAST can reliably identify species within Notodontidae on the basis of COⅠ gene variation.
