Abstract
The Recent Pectinoidea
of the New Zealand region are reviewed. Eight new species are
described from the New Zealand Exclusive Economic Zone: Parvamussium
cancellorum, Cyclochlamys austrina, Cc. delli, Cc.
irregularis, Cc. munida, Cc. pileolus, Cyclopecten
fluctuosus, and Catillopecten tasmani. Nine species are new
records for New Zealand: Parvamussium retiolum Dijkstra,
1995, Pa. vesiculatum Dijkstra, 1995, Sinepecten segonzaci
Schein, 2006, Ciclopecten fluctuatus (Bavay, 1905), Pseudamussium
challengeri (E.A. Smith, 1891), Spondylus occidens G.B.
Sowerby III, 1903, S. proneri Lamprell & Healy, 2001, S.
sparsispinosus Dall, Bartsch & Rehder, 1938, and S.
jamarci Okutani, 1983. Cyclochlamys bacata and Cc.
wanganellica are described from Wanganella Bank, West Norfolk
Ridge, and Cyclopecten textus from the Lord Howe Rise. We
provide new distribution records for Catillopecten murrayi (E.A.
Smith, 1885), Spondylus asperrimus G.B. Sowerby II, 1847 and S.
proneri in the south-west Pacific. Cyclopecten aupouria Powell,
1937 and Cp. mestayerae Dell, 1956 are newly referred
to genus Cyclochlamys Finlay, 1926; Pecten challengeri
E.A. Smith, 1891 is referred to Pseudamussium Morch, 1853. Bathypecten
Schein-Fatton, 1985 is newly synonymised with Catillopecten
Iredale, 1939; and Chlamys consociata E.A. Smith, 1915 is
newly synonymised with Talochlamys dichroa (Suter, 1909).
Brooding is recorded for the first time in Cyclochlamys, and
is also the first record in Propeamussiidae. Pronounced sculptural
change in response to settlement of sponge on the shell is recorded
in Talochlamys dichroa and Zygochlamys delicatula.
Key words:
