Limenandra confusa Carmona, Pola, Gosliner & Cervera, 2014
 
Limenandra confusa
Maximum size:  14 mm.

Identification:  This is a slender species with papillae on the posterior edge of  its rhinophores. The brown-flecked cerata are papillate and are arranged in groups that usually alternate in length. The notum is decorated by a series of bright yellow and pink rings. Occasional animals also have bright pink on the bases of the cerata.

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:  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.
