The generic name Mamoea was used by Begg &
Grant-Mackie (2003: 251) for a new genus of Triassic pleurotomariid
gastropod
with type species M. wairakiensis n. sp. from Murihiku strata
of the
Etalian Stage (Middle Triassic; Late Anisian to Ladinian) of the
Wairaki Hills,
western Southland.
In
proposing this name
we have overlooked the existence of Mamoea Forster & Wilton
(1973: 202) erected for a large group of Recent New Zealand forest
floor
spiders of the Family Amphinectidae, with type species Rubrius
rufus Berland,
1931.
To
overcome this
homonymy we now propose the new name Mamoeatomaria n. gen. for
Mamoea
Begg & Grant-Mackie, 2003, non Forster & Wilton
(1973), with
Mamoea wairakiensis Begg & Grant-Mackie, 2003, as type
species. Its
gender is feminine; the name is a conjunction of the Maori tribal name
Kati
Mamoe and the suffix of Pleurotomaria, the central
genus of the
Pleurotomariidae to which the new genus belongs. It remains a monotypic
genus
known so far only from a single specimen from the Etalian (Late
Anisian-Ladinian; Middle Triassic) of western Southland.
