Abstract

We review the New Caledonian representatives of the Australasian endemic hydroptiline genus Acritoptila, based on examination of a considerable collection of material in the Swedish Museum of Natural History and of types of previously established species. A key for identification of males is given and includes 3 species newly described here: A. parallela sp. n., A. forficata sp. n. and A. macrospina sp. n. For all New Caledonian species, male genitalia are illustrated, and for 5 associated females, distinctive features are illustrated and described.

Highlights

  • Among the microcaddisfly genera (Trichoptera: Hydroptilidae) found in the southwestern Pacific region, several have restricted distributions whereas others are common in the Oriental Region or are cosmopolitan

  • With a narrow distribution, first described for 3 Australian species (Wells 1982). Another 2 Australian species were added by Wells (1990) and 7 species were described from New Caledonia by Kelley (1989) and Wells (1995)

  • Two additional New Caledonian species were described by Oláh and Johanson (2010a), but below one of their names is considered a junior synonym, and 3 new species are described
