Unidentified Facelinid sp. #8
|Maximum size: about 10 mm.
body of this species is translucent gray-orange. The top of its head is opaque
white and there are a series of diamond-shaped gray-white patches on the
mid-line of the notum. The sides of its body have regularly spaced, opaque-white
patches and the cephalic tentacles have an opaque-white sub-medial band. There are
six widely spaced clusters of short, cream cerata that have dark spots near
their tips. The rhinophores are irregularly annulate and have brown tips.
facelinid sp. #8 is known from a single animal found crawling, by day,
on a vertical rock surface at 17 m (57 ft). It was at an exposed to
highly exposed site.
Distribution: Kauai: probably widely distributed in the Pacific.
Taxonomic notes: The Hawaiian animal is similar to animals found in the Marshall Islands by Scott Johnson. Based on its general form and annulate rhinophores, it's probably in Favorinus or Cratena.
It was first
recorded in Hawaii from about 274 meters off shore of the southernmost
tip of Kauai by Eric Shewchuk on Aug. 21, 2020. It's somewhat similar to
"Facelinid sp. 3" in Gosliner, et. al. (2018). However, that species
(as illustrated) has longer cerata and lacks the opaque white patches
below the cerata.
