Abstract A new species of benthopelagic calanoid Copepoda
is described from New Zealand. The species, Bradyidius capax n. sp.
(Family: Aetideidae), is the second species of this genus to be recorded from
New Zealand. B. capax females are close to B. armatusGiesbrecht,
1897 and B. rakuma (Zvereva, 1977). B. capax differs from these
two species by a combination of its small size, hardly divergent rostral
points, fusion line between pedigerous somites 4 and 5 not visible, posterior
corners of pedigerous somite 5 directed straight posteriorly (not divergent
in dorsal view), seminal receptacles occupy 57% of length of genital double
somite measured ventrally, and antennal exopod segment 1 with small seta.
The distribution of B. spinifer Bradford, 1969 is extended along the
continental slope of north-eastern New Zealand and some features previously
undescribed, are illustrated.
