A phylogenetic analysis is presented for Helicophidae genera based on fragments of the three genes COI, 16S and EF‐1a (total 1705 bp) and morphology (70 characters). Molecular data show that both the family Helicophidae + Alloecentrella Wise and the New Caledonian species form monophyletic groups. Monophyly of the New Caledonian Helicophidae based on morphology alone is not supported. Nine new species of Helicopha (Trichoptera, Helicophidae) from New Caledonia are described: H. neocaledonia sp.n. , H. loripes sp.n. , H. angulata sp.n. , H. stellata sp.n. , H. bifurcata sp.n. , H. mouirangensis sp.n. , H. acuta sp.n. , H. taoensis sp.n. , and H. aoupiniensis sp.n. The Helicophidae now include 42 known species of which 18 are New Caledonian endemics. New Caledonian Helicophidae form a monophyletic group, whose species diversity is the greatest amongst the world’s Helicophidae. Descriptions of the females of Helicopha dognyensis and H. ramea, previously known only from males, are the first for females from New Caledonia. Briama Johanson & Ward ( syn.n.) is phylogenetically most closely related to New Caledonian Helicopha and is considered as synonymous. Alloecentrella Wise from New Zealand, previously classified within Calocidae, is more closely related to Austrocentrus Schmid from Chile and is to be classified as Helicophidae.
