The Tigermoths (Erebidae, Arctiinae, Lithosiini) of Papua Indonesia

by Rob de Vos

Oeonistis delia (Fabricius, 1787)

[Noctua delia Fabricius, 1787] [holotype: not located]


Gnophria ceramensis Vollenhoven, 1872 [holotype: Seram, in RMNH]
Tigrioides splendens Lucas, 1890 [type: Queensland, not located yet]
Oenistis (sic) entella braeckeli Debauche, 1938 [holotype: Menado, Sulawesi, in ISNB]

Similar species

Oeonistis delia is very similar to three other Indo-Australian species: O. altica (Linnaeus, 1768), O. entella (Cramer, 1779) and O. lifuensis Rothschild, 1912. Although I have not seen all genitalia I follow Holloway (2001) in his opinion that the four are bona species. The recently described taxon imitaria Orhant, 2000 from Thailand is probably nothing else than altica. The distribution areas from all species are not overlapping.

Oeonistis entella from Ceylon and South India is the smallest species, rather pale and quite easy to distinguish from the others by the retracted dark hind margin on the forewing which does not touch the tornus. Oeonistis altica from Northern India to the Sunda Islands is externally hardly to distinguish from O. delia, this must be done by genitalia. Oeonistis lifuensis from New Caledonia and the Loyalty Islands has its ground colour pinkish orange with a similar dark pattern like the others.
