Diplonevra bifasciata ( Walker, 1860)

Phora bifasciata Walker, 1860: 172 . Type locality: Makessar , Celebes (Sulawesi, Indonesia).

Diploneura (Tristoechia) bifasciata: Schmitz, 1929: 105 (subgeneric assignment).

Phora egregia Brues, 1911: 534 . Type locality: Formosa (Taiwan) (synonymy).

Phora bicolorata Becker, 1914: 88 . Type locality: Formosa (Taiwan) (synonymy).

Phora cinctiventris Senior-White, 1922: 154 . Type locality: India (synonymy).

Diagnosis. This species can be distinguished from other Diplonevra species by the combination of the following characteristics: inner face of hind trochanter with one stout seta; ventrobasal area of inner face of hind femur highly sclerotized proximally, with two short setae; hind tibia with three longitudinal setal palisades and one anterodorsal bristle before apical quarter; wing vein M 1 straight; male abdominal tergites 2–5 dark brown and venter pale yellow; female abdominal tergites 1, 5 and venter pale yellow (modified from Liu & Yang 2016).

Remarks. This species is mainly distributed in southeastern Asia. The Korean distribution of the species has been recorded in checklists only (ZSK 1968; ESK & KSAE 1994; Paek et al. 2010; NIBR 2019). Although we were unable to examine the specimens of this species, photographs of a female specimen were available for proper identification of the species based on overall appearance (wing vein M 1 straight, abdominal tergites 1 and 5 pale yellow, abdominal tergites 2–4 dark brown, and abdominal venter pale yellow), which were consistent with the features of D. bifasciata . The photographs were available from two research reports ( Kwon et al. 2015; 2018). The collection site of the specimen was provided by Kwon et al. (2015) ( South Korea: Jeollanam-do, Naju-si, Daeho-dong, near Dongsin University, 35°02′54.8″N, 126°42′59.2″E), but the voucher specimen is missing. The specimen was misidentified as D. abbreviata in a later report ( Kwon et al. 2018: 61).

Distribution. Korea (Jeollanam-do), Russia (Far East), China, Japan, Thailand, India, Oriental Region.
