Caledonia (Coleoptera: Tenebrionidae),. Memoirs of the Queensland Museum 49(1):
441-445. Brisbane. ISSN 0079-8835.
Aoupiniapseudohelea, new genus and species, is described fromAoupinie Special Fauna
Reserve, New Caledonia, where it occurs in rainforest leaf litter. Although strongly
resembling the unrelated Australian tenebrionine Helea Latreille,Aoupinia belongsto the
lagriine tribe Adeliini, a Gondwanan group which has diversified extensively in New
Caledonia. There is an analysis showing that the new taxon belongs to a group often
Australian andNewCaledonian genera termed the northern squalid group, but that it isof
