Limenandra confusa Carmona, Pola, Gosliner & Cervera, 2014
Maximum size: 14 mm.
Identification:
This
is
a slender species with papillae on the posterior edges of
its rhinophores. The brown-flecked cerata are papillate and are
arranged in groups that usually alternate in length. The notum is
decorated with bright yellow patches and pink rings. Rarely, the cerata
may have bright pink bases. In some animals, the notum may be
tuberculate and the yellow pigment may be confined to the tubercles.
Rarely, the pink pigment may be reduced to a
central dot or be completely obscured by white pigment.
Natural history:
Limenandra confusa
is a moderately common diurnal species found in protected to exposed
rocky habitats and in Halimeda
kanaloana beds. It occurs at < 1 to 18 m (< 3 to 59 ft).
It jerks its cerata rhythmically while crawling and lays a weakly
"kinked", white egg mass.
Distribution:
Big Island, Maui, Oahu and Kauai: widely distributed in the Indo-Pacific.
Taxonomic notes: Some sites list this species as Limenandra nodosa or Baeolidia nodosa. However, the
descriptions of Baeolidia nodosa in Kay, 1979 and Gosliner, 1980 apparently refer to Limenandra
rosanae, instead, as does the photo in Bertsch and Johnson, 1981.
It was first
recorded in Hawaii at Magic Island, Oahu by Scott Johnson on Oct. 12,
1979. Carmona, et. al., 2013 found Limenandra nodosa to be restricted to the Atlantic. (Note 1)

Observations and comments:
Note
1: There's some chance that smooth and tuberculate animals could prove distinct.
