Kaniwhaniwhanus gen. n. is described for the first time from New Zealand. D
iagnoses of the male image, pupa, and larva are presented. Kaniwhaniwhanus
can be distinguished by a combination of hairy eyes, pigmented wings, prese
nce of bare anal point, and absence of inferior volsella in the male image;
the absence of a thoracic horn, presence of anteriorly directed comb-like
hooklets on abdominal tergites TII-TV, evenly distributed shagreen on poste
rior abdomen tergites, and the absence of anal macrosetae in the pupa; and
by a 4-segmented antenna, broad single tooth of mentum with four pairs of l
ateral teeth, and the presence of paired medio-lateral lobes of the mentum
in the larva. Kaniwhaniwhanus appears to be monotypic and is designated by
the type species, Kaniwhaniwhanus chapmani. Larvae of Kaniwhaniwhanus chapm
ani are known from North Island streams and have been recorded from Lake Gr
asmere in the South Island.
