Atagema sp. #18
|Maximum size: 4 mm.
is an elongate, yellow to white species marked with irregular
violet-brown bands near the branchia and rhinophores. The papillae are
short and blunt while the rhinophores have only five or six lamellae
(in contrast to Atagema echinata).
Atagema sp. #18 is known from five animals. Two were found at an
exposed rocky site at < 5 m (< 16 ft). Another was found in a Halimeda kanaloana bed at between 8
and 20 m (26 and 66 ft).
Maui and Oahu: possibly also known from Japan and Papua New Guinea.
The papillae in these animals are similar to those of Atagema
intecta suggesting that
they might ultimately turn out to be very small juveniles of that
species. Or, they could be related to Atagema sp. 5 in Gosliner, et. al. (2015).
