Abstract
A new species in the anthiadine genus Luzonichthys
Herre, 1936 is described from a specimen collected
at a depth of 83 m in a mesophotic coral ecosystem
at Rapa Nui (Easter Island). Luzonichthys kiomeamea
n. sp. can be distinguished from the 7 other valid
Luzonichthys species by anal-fin and pectoral-fin
counts, the number of lateral-line scales, the number
and arrangement of gill rakers, and coloration pattern.
Mitochondrial DNA sequencing shows that the new species
is more than 11% divergent in the COI sequence (and
about equally distant) from Luzonichthys waitei,
L. seaver, L. earlei (Hawaii),
and L. aff. earlei (Coral Sea). Given
the isolation of the island, and the uniqueness of
its fish fauna, we suspect that the new species is
endemic to the mesophotic reefs of Rapa Nui.
