Abstract
The new species Pseudojuloides
polackorum is described from seven specimens collected
off the east coast of South Africa and from near Mombasa,
Kenya. The species closely resembles the widespread
Indo-Pacific congener P. cerasinus Snyder 1904
and replaces it along the continental south-western
Indian Ocean, including Madagascar. The new species
is distinguished from P. cerasinus by the absence
of a blue stripe behind the eye, a salmon-tinged lower
half of the head, a wider orange band along the body
(vs. narrower and yellow), and a narrower blue lateral
stripe along the body above the band with linear projections
into the band. In addition to the color differences,
there is a 9.48% divergence in the barcode DNA sequence
COI from P. cerasinus from Hawaii, the type
location of the species (minimum interspecific distance
by K2P; 8.74% divergence pairwise).
