Pseudojuloides cerasinus, the smalltail wrasse or the pencil wrasse, is a species of marine ray-finned fish, a wrasse from the family Labridae. It is found in the tropical Pacific Ocean and was previously considered to have a much wider distribution but the recognition of new species has reduced this wide range.
Pseudojuloides cerasinus in their male or terminal phase has a distinctive blue mid-lateral stripe which is situated immediately above a yellow stripe and the posterior portion of the caudal fin is black, [3] edged with blue. [4] In these males the body is an overall green colour and they have a single blue facial stripe. [5] Some males show black spots on the membranes between the first two spines on the dorsal fin. Females of all species in the genus Pseudojuloides tend to be orange or reddish in colour. [3] This is a small species which grows to a total length of 103 millimetres (4.1 in). [1]
Pseudojuloides cerasinus is known only from the seas around Hawaii. [2]
Pseudojuloides cerasinus is frequently recorded in clear lagoon and near seaward reefs over coral rubble substrates, it is infrequently recorded over live coral and clumps of algae. It inhabits depths of around 3–61 metres (9.8–200.1 ft), although it is more common at depths in excess of 21 metres (69 ft). [2]
Pseudojuloides cerasinus was formerly regarded as having a wide Indo-Pacific distribution but the taxon P. cerasinus sensu lato is now widely regarded as a species complex and P. cerasinus sensu stricto is now thought to be endemic to Hawaii. [2] The three Indian Ocean species P. xanthomos from Mauritius, P. polackorum from South Africa to Madagascar and P. kaleidos of the Maldives to the Greater Sundas were the first to be recognised while P. splendens from the western Pacific Ocean and P. polynesica of Polynesia were recognised more recently. [5] [3]
Pseudojuloides cerasinus was originally described as Pseudojulis cerasina in 1904 by the American ichthyologist John Otterbein Snyder (1867-1943) with the type locality given as Honolulu. [6] When Henry Weed Fowler described the genus Pseudojuloides he designated Pseudojulis cerasina as the type species of the new genus. [7]
Pseudojuloides is a genus of wrasses native to the Indian and Pacific Oceans.
The Christmas wrasse, also known as the ladder wrasse, green-barred wrasse or green-blocked wrasse, is a species of ray-finned fish, a wrasse from the family Labridae which is native to the Indian Ocean and the western Pacific Ocean.

Novaculichthys taeniourus, also known as the rockmover wrasse, carpet wrasse, dragon wrasse, bar-cheeked wrasse, olive-scribbled wrasse or reindeer wrasse, is a species of wrasse mainly found in coral reefs and lagoons in the Indo-Pacific region. These include habitats in the Gulf of California to Panama; tropical Pacific Ocean islands including Hawaii; the Philippines, Indonesia and Australia; and the Indian Ocean to the east coast of Africa. The common name, "rockmover wrasse", comes from their behavior of upending small stones and reef fragments in search of prey. This species is the only known member of its genus.
