摘要： The Nyctegretis seminigra sp. nov. from China is described. The new species is similar to N. triangulella, but can be distinguished by its bicolored forewing pattern and a pointed protrusion on the costa of the valva in males, as well as the signum location in the females. Detailed illustrations of adults, wing venation, and the male and female genitalia of the new species are provided. The DNA barcode of the new species has been successfully sequenced. Genetic divergence analyses among species within Nyctegretis are conducted using pairwise analysis, revealing that all included species exhibit highly species-specific DNA barcodes. The complete mitochondrial genomes of the new species and its related species, N. triangulella, are obtained through next-generation sequencing, followed by a comparative analysis. Furthermore, phylogenetic analyses based on mitogenomes through Maximum Likelihood and Bayesian Inference approaches are also performed to elucidate the taxonomic status of the new species.
