Revision of the Nyctemera clathratum complex (Lepidoptera: Arctiidae)

The Nyctemera clatrathum complex (Lepidoptera: Arctiidae, Arctiinae, Callimorphini) is revised. It consists of seven species, occurring on New Guinea and surrounding islands, of which three are new to science: Nyctemera giloloensis sp. n., N. oninica sp. n. and N. dauila sp. n. Two taxa are synonymized: Leptosoma absurdum Swinhoe, 1892 syn. n. of Leptosoma clathratum Snellen van Vollenhoven, 1863 and Deilemera pratti Bethune-Baker, 1904 syn. n. of Nyctemera mesolychna Meyrick, 1889. Lectotypes are designated for Deilemera pratti Bethune-Baker,
1904 and Deilemera absurdum latimargo Rothschild 1915. Adults and genitalia of all species are figured and distribution maps are presented.
