The subgenus Oropeza Needham, 1908 (Diptera: Tipulidae: Dolichopeza) comprises 27 described species distributed across the Holarctic region. Certain Oropeza species have been reported in neighboring countries of the Korean Peninsula―6 species in Japan, 3 species in China, and 4 species in Russia. Some researchers, such as Byers (1961) and Savchenko (1983), suggested that the distribution of Oropeza cover the East-Palearctic regions, including the entirety of the Korean Peninsula. However, previous records of Oropeza from the Korean Peninsula have not been accepted because of the lack of comprehensive species-level investigations in this region. In this study, we present a new record of the species Dolichopeza (Oropeza) satsuma (Alexander, 1918) in South Korea, with redescription and photographs: general habitus, wing veins, and male genitalia. This finding marks the rediscovery of the subgenus Oropeza in the Korean Peninsula.

The cranefly genus Tipula Linnaeus, 1758 (Diptera: Tipulidae) contains up to 2,790 species in 40 subgenera distributed in all biogeographic regions. The richest fauna is known in the Palaearctic region with 1,224 speices. The Korean Tipula was recorded for the first time by Alexander in the early 20th century. According to the ‘Checklist of Korean aquatic insects (2014)’ 30 species in 12 subgenera are recorded in Korea. Baek and Bae (2016) additionally reported 5 species new to Korea. We reviewed all known species of the genus Tipula in the Korean Peninsula. We also provided a key to the subgenera and species.
