Abstract
The genus Latrunculia
in New Zealand was believed to be represented by at least three species: L. brevis
Ridley & Dendy and two undescribed species. However, results from recent studies indicate that the genus contained a complex of at least eight genetically distinct species. In this paper we revise the taxonomy of Latrunculia
in New Zealand and describe nine new species. Eight of these were previously identified using genetic techniques (i.e., L.
kaakaariki
sp. nov., L.
duckworthi
sp. nov., L.
procumbens
sp. nov., L.
wellingtonensis
sp. nov., L.
kaikoura
sp. nov., L.
triverticillata
sp. nov., L.
fiordensis
sp. nov., and L. millerae
sp. nov.) and one (L.
oxydiscorhabda
sp. nov.) was distinguished based only on morphological differences. The species described fall into two morphological groups, spinispiraefera
and triverticillata
, which can be diagnosed by the number of whorls present along the discorhabd axis. The status of L. brevis
, and other subantarctic species (i.e.
, Latrunculia bocagei
, L. antarctica
, L. lendenfeldi
, L. spinispiraefera
) is discussed; all of these species are considered to be valid but not conspecific with any of the species described here.
