Tenellia sp. #26
|Maximum size: 3 mm.
body of this aeolid is translucent-cream. The rhinophores have apical
and medial bands of opaque-white pigment separated by a pale orange
band. The cephalic tentacles have an apical white band. Prominent brown
branches of the digestive gland form a loop behind the head and fuse
into a single branch behind the second ceratal cluster. That branch
backward on the top of the notum with side-branches running into
the cerata. The cerata are tipped with
translucent-white and have opaque-white blotches distally. The top of
the head is opaque-white and there are two large patches of opaque-white
separated by a clear area on the anterior portion of the notum. A small
white patch is present on the posterior portion and smaller
patches of white also run along the sides of the body. The eye spots
surrounded by translucent patches. (Note #1)
Tenellia sp. #26
is known from a single animal found on a rock wall at a depth of about 18 m (60 ft).
Distribution: Niihau; perhaps, also known from the Marshall Islands and/or Indonesia?
was first recorded in Hawaii from off Lehua Islet, Niihau by April McCormack on Aug. 28, 2019. It may be related to "Tenellia sp. e867" on Scott Johnson's site. It may also be related to "Tenellia sp. 37" in Gosliner, et. al. (2018).

Observations and comments:
1: The animal is missing part of its left rhinophore. In the photo on this page, the first ceras in the first
ceratal cluster on the left side is bent far forward obscuring the base
of the damaged rhinophore. The first ceratal cluster on the right side
is probably also missing.
