Biology:Coryphella

From HandWiki

Coryphella is a genus of sea slugs, specifically aeolid nudibranchs, marine gastropod molluscs in the family Coryphellidae.[1]

Taxonomy

Coryphella was originally described in an 1850 paper, and included three original species; Coryphella landsburgii, Coryphella rufobranchialis, and Coryphella pellucida.[2] The family Coryphellidae was first established in 1889 by Rudolph Bergh,[3] and was re-established in a 2017 study.[4] Molecular studies have found that many existing genera were actually synonymous with Coryphella, leading to many genera being merged.[5] However, these studies had failed to take morphological analysis into account, the "lumping" of several genera under Coryphella leading to loss of differentiation. Thus in a 2025 study[6], after full molecular and morphological analysis, the genus Coryphella was restricted, previously synonymized genera reinstated, and two new genera established.

Species

According to Korshunova et al. (2025), species within the genus Coryphella are as follows[6]:

  • Coryphella longicaudata O'Donoghue, 1922
  • Coryphella pseudoverrucosa Martynov, Sanamyan & Korshunova, 2015
  • Coryphella verrucosa M. Sars, 1829
