Triscaedecia septemdactyla ( Pagenstecher, 1900)

( Figs 2 , 7 , 14 )

Hofmannia septemdactyla Pagenstecher, 1900: 241 . Type locality: Bismarck Islands.

Material examined. 1 ♂, N. Dutch New Guinea, Waigeu Camp Nok. 2500 ft. iv. 1938. L.E. Cheesman (B.M. 1938-593), in BMNH .

Diagnosis. This species resembles T. dactyloptera in wing color and pattern but is distinguished by its smaller size (wingspan only 13 mm in specimen examined), paler color and a wide white transverse stripe across the middle of the fore wing which includes the discal spot and approaches the costa. Gielis (2009) includes additional illustrations of the adult moth and male genitalia.

Distribution: New Guinea and the Bismarck Archipelago.

Notes. Unfortunately, the female genitalia of T. septemdactyla are unknown.
