Abstract
A new species of triplefin,
Enneapterygius niue, is described on the basis
of three specimens from Niue and Samoa. The new species
is a medium-sized species of barred Enneapterygius,
characterized by 13–15 spines in the second dorsal
fin, 18–20 anal-fin soft rays, 14–19 + 16–20 lateral
line scales, 33–36 total lateral scale rows, eye diameter
94–128, preorbital 50–75, body depth 176–206, preanal
fin length 483–538 (last four measures in thousandths
of SL), sides of body with a pattern of two short
and five complete bars, pectoral-fin base with a vertical
dark bar, preorbital with an oblique dark band, dorsal
fins pale except for a dusky base, anal fin dark grey
in male and with four oblique brown bands in female,
pelvic fins white, and caudal fin pale. The new species
is compared with similar species. A revised key to
the species of Enneapterygius in the Indo-Australian
Archipelago and the western Pacific is presented.
