Distribution


Description

Part of the Eviota zebrina species complex which includes eight described closely-related species, and likely more undescribed species in the Pacific. While E. zebrina is restricted to the Indian Ocean, the species pictured here from Vanuatu is likely an undescribed species within the complex, most closely resembling E. zebrina (Tornabene et al. 2021). 

Like some other species within the complex, the pictured specimens exhibit a red stripe through the centre of the iris, which is lacking in E. pseudozebrina described from Fiji. A light bar crosses above and below the pupil, topped by a red bar which is broken up by irregular light areas. A distinct reddish 'A' shaped blotch is seen immediately behind each eye, and naris are long and reddish brown. Lacks large red and yellow blotches on the caudal peduncle, seen E. zebrina and others within the complex. 


Information

Max Size: N/A cm

Sea Temperature Range: N/A

Depth: N/A

Habitat Generalization Index: N/A

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Not Evaluated

Occurrence: Common (33.3% of sites)

Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed

Abundance: Many (24 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
