摘 要:Island ecosystems support diverse aquatic invertebrate communities comprising endemic *** of existing species is important for *** this study,a checklist of marine opisthobranch from the Republic of Mauritius is presented.A combination of benthic surveys(50 m×5 m in triplicates),rover diving techniques and photo documentation were used over two years(2018–2020)within 35 sheltered and unsheltered *** and molecular analysis were used for *** composition within sheltered and unsheltered areas in Mauritius was estimated using the Bray-Curtis *** checklist featured 117 species belonging to 61 genera and 28families,of which 13 are new *** findings increased the knowledge of opisthobranch diversity from the Mauritius by 15.4%.Among the listed species,the distribution range of Cyerce nigra,Actinocyclus papillatus,and Phyllidia picta extended from the Western Pacific to the South Western Indian *** analysis of the undescribed Gymnodoris *** it resembled Gymnodoris *** Hawaii and were different by a genetic distance value of 10.6%.The species richness and evenness were higher within the sheltered regions of Mauritius which harboured the food resource of *** areas as compared to unsheltered regions were heavily populated,suggesting the probable influence of wave actions on opisthobranch diversity and *** order Nudibranchia was reported as most speciose,with 86 *** Sacoglossa and Nudibranchia were observed only on macroalgae and sponges *** abundance was also recorded on shipwrecks which are the most common form of artificial *** the inclusion of observations from previous studies,201species belonging to 94 genera and 36 families are now known from the Mauritius.
