- Abstract
- DNA barcoding is useful for identifying species that are difficult to distinguish via morphological analysis. However, if the public DNA barcode database includes misidentified DNA samples, subsequent molecular studies could generate incorrect results. Here, we report a misidentified DNA barcode for the North Coastal Black Field Cricket Teleogryllus (Brachyteleogryllus) marini. T. (B.) marini is routinely misidentified using DNA barcoding; it has been reported as Teleogryllus (Brachyteleogryllus) commodus since its misidentification in various studies of Asian samples. Here, we report the first occurrence of T. (B.) marini in Korea, along with its morphological diagnosis, bioacoustic signals, and DNA barcoding findings. T. (B.) marini is transferred to the subgenus Bra-chyteleogryllus from the subgenus Teleogryllus, based on the male genitalia morphology and phylogenetic analysis. Genetic distance analyses have shown that cytochrome c oxidase I barcoding is useful for species identification of the genus Teleogryllus, but detailed morphological investigations are essential for DNA barcoding before any molecular study.
