Note

The specimens examined by Lallemand (1959, 1963) and Fennah (1977), erroneously identified as B. collaris , 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 entirely yellow-brown, without lines or spots ( Fig. 4E )

(2) bulge between frons and vertex black ( Fig. 4C )

(3) abdomen mostly black dorsally ( Fig. 4A ) and brown ventrally ( Fig. 4B )

(4) tegmina opaque on basal half and infuscate on distal half ( Fig. 4A )

(5) hind wings largely hyaline, with basal angle yellowish ( Fig. 4A )

Material examined

Holotype INDONESIA: ♀ ( Fig. 4 ), Morotai Island, 2°20′52″ N, 128°27′52″ E [Morty, Wallace / glued on the reverse: 67 66] [M] [Type] [ collaris ] [ BMNH ( E), # 651887 ] (BMNH).

Distribution

Morotai Island (holotype) and Halmahera Island ( Breddin 1900) ( Fig. 3 ).
