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 )
