Revision of the labrid fish genus Pseudolabrus and allied genera

Abstract

Six labrid genera, austrolabrus Steindachner, Dotalabrus Whitley,Eupetrichthys Ramsay & Ogilby, NOTOLABRUS new genus, PictilabrusGill, and Pseudolabrus Bleeker, are recognised as forming a monophyleticassemblage, here referred to collectively as pseudolabrines. Thisgroup comprises 23 species, including two new species described herein:Dotalabrus alleni n.sp. and Pictilabrus viridis n. sp., both fromsouth-western Australia. The gneus Suezichthys (= Suezia) Smith,previously considered closely related to Pseudolabrus, is excluded.Keys, diagnoses and descriptions of the genera and species are given.The pseudolabrines are provisionally placed in the tribe Julidini,and appear to be the plesiomorphic sister group of all other julidines.Within the pseudolabrine group, cladistic analysis supports the separationof NOTOLABRUS n.gen., previously included with Pseudolabrus, andthe inclusion of Lunolabrus Whitley as a subgenus of Pseudolabrus.[Notolabrus parilus (Richardson, 1850) comb. nov. (Tautoga parila);N. gymnogenis (Gunther, 1862) comb. nov. (Labrichthys gymnogenis;N. tetricus (Richardson, 1840) comb. nov. (Labrus tetricus); N. celidotus(Bloch & Schneider, 1801) comb. nov. (Labrus celidotus); N. cinctus(Hutton, 1877) comb. nov. (Labrichthys cincta); N. fucicola (Richardson,1840) comb. nov. (Labrus fucicola); and N. inscriptus (Richardson,1844-48) comb. nov. (Labrus inscriptus) also are described.].
