from Australia (Percomorpha: Apogonidae: Gymnapogon)

Abstract
A new species of cardinalfish, Gymnapogon velum,
is described from two specimens from Australia, one
from the northwest shelf of Western Australia and
the other from Queensland. The new species is placed
within Gymnapogon based on caudal osteology,
one spine present on the preopercle edge, a single
rod-like postcleithrum, as well as a scaleless head,
body, and fins. It is distinguished by having an elongate
body with relatively deep soft dorsal and anal fins,
a rounded caudal fin with 15 branched principal caudal-fin
rays, 13 soft dorsal-fin rays, 12 or 13 anal-fin rays,
10 or 11 upper and lower procurrent caudal-fin rays,
and a single smooth spine on the edge of the preopercle.
The high dorsal and anal fin-ray counts separate the
new species from all congeners. Gymnapogon annona
(Whitley, 1936) is redescribed due to discrepancies
between the original description and illustration
of the holotype.
