Brithura Edwards, 1916 (Diptera: Tipulidae) is a small genus of crane flies currently comprising 16 described species distributed across the East Palaearctic and Oriental regions. Although the adults of this genus rank among the largest representatives of the family Tipulidae, their immature stages have remained undocumented until now. In this study, mitochondrial cytochrome c oxidase subunit I (COI) gene fragment sequences (DNA barcodes) of Brithura sancta Alexander, 1929 were analyzed using both recently collected adult specimens from the Republic of Korea and historical museum specimens from China (collected in 1933). These sequences were compared with COI data obtained from larvae collected in Republic of Korea. We present the first description, with detailed illustrations and ecological information, of the previously unknown final instar larva of Brithura, specifically for the East Palaearctic species B. sancta. Diagnostic larval characters for the genus are discussed. Additionally, a redescription and comprehensive morphological documentation of the adult male and female B. sancta, including habitus and genitalia, are provided. This study represents the first phylogenetic contribution to the taxonomy of Brithura larvae based on mitochondrial COI sequence data.
