Tritonia flemingi
(Powell, 1937)

Family: Tritoniidae


North Island of New Zealand


Poor Knights Islands, NE New Zealand, 9 December, 2001, approx 5m deep. Approx 10mm. Photo: Gareth Jones.

Powell illustrates this as having a green background colour but Willan & Morton (1984) describe it as a:
'sooty black slug ... with about 8 greyish tufts arising fromn the keeled notal margin. .. rhinophoral sheaths are large simple-margined and cup the orange-red, highly subdivided rhinophoral clavi. Back and sides bear low, whitish pustules. Oral veil bilobed, and not fimbriated as in other Tritonia species.'

It grows to about 12mm, and is found from the intertidal to 12m throughout the North Island of New Zealand. It is appears to be uncommon and nothing is known of its biology.
