Birdantis delibuta Stål, 1863 Figs 3, 6 Birdantis delibuta Stål, 1863: 582 (described; compared with B. decens Stål, 1863). Birdantis delibuta – Metcalf 1947: 92 (catalogued). — Lallemand 1959: 194 (keyed; senior synonym of B. trilineata (Schmidt, 1926) (error!); recorded from Buru and Ambon Islands (errors!)); 1963: 11 (same as preceding reference). — Fennah 1977: 376 (keyed, listed). — Nagai & Porion 1996: 14 (catalogued). non Birdantis delibuta – Kirkaldy 1913: 11 (tentative attribution of an immature specimen from Ambon Island to B. delibuta). — Fennah 1977: fig. 7 (anal tube). — Nagai & Porion 1996: pl. 3, fig. 56 (habitus). Note The specimen mentioned by Kirkaldy (1913) as well as those illustrated by Fennah (1977) and Nagai & Porion (1996), erroneously identified as B. delibuta, were actually specimens of B. trilineata (Schmidt, 1926). Diagnosis This species can be separated from all other species of Birdantis by the following combination of characters: (1) frons yellow-brown with three dark brown lines limited dorsally to level of middle of eyes, and with the two lateral ones extending on to clypeus (Fig. 6B) (2) bulge between frons and vertex dark brown and vertex yellow-brown (Fig. 6C) (3) tegmina opaque on basal half and infuscate on distal half (Fig. 6A) (4) hind wings largely smoky, with a basal red marking (Fig. 6A) (5) anterior margin of frons in dorsal view rounded but not strongly protruding (Fig. 6C) Material examined Holotype INDONESIA: abdomen lost (Fig. 6), Ternate Island, 0°48′07″ N, 127°20′41″ E [Ternate] [Stevens] [234, 59] [Birdantis delibuta Stål] [Riksmuseum Stockholm] [NHRS-HEMI 000000181] (NHRS).
