Another Lomanotus from western Pacific

From: Scott Johnson


Hi Bill,

I have this one tentatively identified as Eumenis marmorata Alder & Hancock, 1846. The animals are extremely variable in coloration. I've found them on two occasions, and both times there were several individuals, no two of them alike in color. My specimens ranged from about 5 to 10 mm in length, and they are shown here on what is apparently their prey hydroid. They are rare here in the Marshalls, but I've found one group at both Kwajalein and Enewetak Atolls.

This definitely a species of Lomanotus (=Eumenis). L. marmoratus has quite prominent papillae or cerata all along the mantle edge. It also has two pairs of oral (head) tentacles, and is found along the Atlantic coast of Europe.

I have found this species in New Caledonia. My photos of an animal from there, show that this species has only one pair of tentacles and the papillae are on the whole restricted to the mantle lobes. Unless there is a name lurking around in some forgotten publication I think this species has not been named.
