Abstract
The new labrid fish species,
Pseudojuloides labyrinthus n. sp., is described
from three specimens obtained via the aquarium trade
from Kenya, in the western Indian Ocean. The species
is similar in appearance to other Indo-Pacific Pseudojuloides
in the P. severnsi complex, distinguished mainly
by the markings of the terminal-phase male, which
includes a maze of lines on the head and three thicker
blue stripes along the rear body. Despite the similarity
in appearance, the new species is 9.66% divergent
in the sequence of the mtDNA barcode marker COI (minimum
interspecific divergence, pairwise; 10.54% K2P distance)
from its nearest relative, P. edwardi, also
found in Kenya. A neighbor-joining tree and genetic
distance matrix is presented for 12 of the 14 known
species in the genus Pseudojuloides.
