A new species of Pseudojuloides (Perciformes: Labridae) from the south-western Indian Ocean

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
