Marsenina
(?)
sp. #1
 
Marsenina(?) sp. #1
Maximum size:  18 mm.

Identification:  This is a flattened, translucent species with a finely papillate dorsal surface. The dorsum is decorated with variably developed radiating bands of opaque-white and variably developed blood-red patches. The edges of the patches often have a few contrasting white flecks and the papillae are faintly tipped in violet-brown. In some animals dendritic brown lines are present in the lateral red spots. There are a few variably developed, translucent tubercles in the center of the dorsum.

Natural history:  The only Marsenina(?) sp. #1 we've found on Maui was on a waxy, white tunicate on which it was well camouflaged (and, possibly feeds?). It was under a rock in a highly protected rocky habitat at 3-5 m (10-16 ft). In contrast, it appears to be fairly common in protected, rocky habitats on Oahu. Unlike other Hawaiian velutinids, it temporarily roles it's mantle into a tube when it's overturned.

Distribution:  Maui and Oahu.

Taxonomic notes:  It was first recorded in Hawaii from Kahului Harbor, Maui by CP on April 8, 2010. We've tentatively assigned it to Marsenina because of its morphological similarity to some photos of the west coast species, Marsenina stearnsii.
