Abstract The three larval stages of two New Zealand species
of
Meropathus Enderlein, 1901--
M.
campbellensis Brookes,
1951 and
M. zelandicus Ordish, 1984--are fully described, including the
first detailed account of their chaetotaxy. The second instar of a third
species--
M. johnsi Ordish, 1971--is recorded but not fully described.
The morphological characters which distinguish the larvae of
M.
campbellensis from those of
M. zelandicus, as well as those
distinguishing them from other hydraenid larvae, are given. A key to identify
the three larval instars within a species is also given. The presence or
absence of larval anal hooks in Hydraenidae is discussed.
