Chromodoris cf. lochi from Marshall Ids

Hi Bill,

Thought you might be interested in a potentially different species in the Chromodoris elisabethina color group. I have it in my Marshall Islands list as Chromodoris sp. E248. It's a rare one here in the Marshalls. I've seen three specimens at Enewetak and one at Kwajalein Atoll. All were in ledges on lagoon pinnacles at night at depths of 10-15 meters. Similar species Chromodoris elisabethina and Chromodoris annae shared the same habitat; Chromodoris sp. E248 is lots more common and C. annae is about as rare. The teeth are typical of Chromodoris. The coloration of the scan is pretty accurate. The body is basically light gray, a bit darker in three indistinct bands that cross the notum, and it is longitudinally streaked with black. The wide white margin is tinged on some parts with light orange. Any suggestions on an id?

I have photos and specimens of this from Tahiti and New Caledonia. It comes quite close to Chromodoris lochi but the reddish marks along the mantle edge, and the distinctly pigmented gills and rhinophores are not found in that species. There are slight differences in the outer lateral teeth of the radula but I need to scan more radula of C. lochi the ones I have were done many years ago and out techniques are a lot better now. I've basically been waiting until more material is available.
