Scientific Name: Xyrichtys incandescens Edwards & Lubbock, 1981
Common Name(s):
English Razorfish
Taxonomic Notes: There is some taxonomic confusion between the species under Xyrichtys and Iniistius. The genus Iniistius has been considered a synonym of Xyrichtys by some authors but it is now recognized as a separate genus, distinct from Xyrichtys (Randall and Earle 2002, Randall et al. 2002). Seventeen species are included in Iniistius and they are: I. aneitensis, I. auropunctatus, I. baldwini, I. bimaculatus, I. cyanifrons, I. dea, I. evides, I. griffithsi, I. jacksoniensis, I. melanopus, I. pavo, I. pentadactylus, I. spilonotus, I. trivittatus, I. twistii, I. umbrilatus, and I. verrens.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-03-03
Assessor(s): Ferreira, B.P., Feitosa, C.V., Sampaio, C. & Bertoncini, A.
Reviewer(s): Craig, M.T. & Carpenter, K.E.
This species has a restricted distribution and occurs in relatively low abundances. Although recorded in locations other than the Oceanic islands in the coast of Brazil, it is rare in those locations. However, most of its range of distribution is inside protected areas. It is rarely collected for the aquarium trade and this is not thought to be a threat. This species is listed as Least Concern.

Geographic Range [top]

Range Description:This species is endemic to northeastern Brazil. It was recorded from Parcel Manoel Luis Reefs (Rocha and Rosa 2001), Atol das Rocas (Rosa and Moura 1995), Fernando de Noronha (Feitoza et al. 2003). It has been observed in the Parcel Manuel Luis (MA) (B. Ferreira pers. comm. 2008 as pers. comm. from Luiz Rocha) and in the coast of Rio Grande do norte state (B. Ferreira pers. comm. 2008 as pers. comm. from C. Sampaio) between depths of 30-35 m. Rodrigo Leão has collected an specimen in Ceara state (MZUSP).

Population [top]

Population:There is no population information available for this species. In Atol das Rocas, it was only observed but not recorded during belt transect census (Rosa and Moura 1995) probably due to its area of occurrence (sand bottom).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is known from Brazilian offshore islands, where coral-algal reefs are the main coastal habitats, and deep reefs (42 m) at the States of Ceará and Rio Grande do Norte (Sampaio et al. 2006).

It was observed to form groups of up to 30-40 individuals (Lubbock and Edwards 1981). Razorfishes spawn only in pairs (Clark 1983, Thresher 1984, Victor 1987) daily, during a late afternoon spawning period, all year-round (Clark Shen and Scarr pers. obs.)

Use and Trade [top]

Use and Trade: This species is collected for the aquarium trade. There are rare cases of collection at Ceará ( Brazil) (C. Sampaio pers comm. 2009) despite the ban on collection of Brazil endemic fishes for the aquarium trade.

Threats [top]

Major Threat(s): There are no major threats known to this species, although it is collected for the aquarium trade but only rarely.

Conservation Actions [top]

Conservation Actions: This species distribution overlaps two important protected areas, Fernando de Noronha National Park and Atol das Rocas Biological Reserve. Brazilian national Law (IN 202, 2008) bans collection of oceanic island endemic fish for aquarium trade, so it is protected from harvesting.
