Study On The Taxonomy And Zoogeography Of Infraorder Stenopodidca (Crustacea: Decapoda: Pleocyemata) From China Sea

The decapod infraorder Stenopodidea includes three families: StenopodidaeClaus,1872, Spongicolidae Schram,1986and Macromaxillocarididae Alvarezet al.,2006. Except for family Macromaxillocarididae with one species, Stenopodidea arewidely distributed in tropical and subtropical regions around the world. The species offamily Stenopodidae are common in shallow waters less than200m, while those offamily Spongicolidae are usually commensals with deep-sea hexactinellid sponges.The Stenopodidea was poorly known in China.Currently only three species from threegenera were reported.This study is based on collections in the Marine Biological museum（MBM）ofChinese Academy of Sciences, including the deep-sea specimens from the SouthChina Sea collected by Chinese “Jiaolong” manned submersible in June,2013. Thisdissertation describes and illustrates the species from Chinese waters, including3genera3spp. of family Stenopodidae and5genera8spp. of family Spongicolidae, inwhich,2species are new to science, i.e., Microprosthema personatum sp. nov.,Globospongicola jiaolongae sp. nov., and5species were not previously recordedfrom Chinese waters. Keys for genera and species are provided. A brief discussion ofthe biogeographic features of the Chinese species is provided, with comparison withneighbor regions, as well as a brief discussion of the association of sponicolid specieswith other marine living organisms.This study is the first approach of the taxonomy of the Chinese stenopodideanshrimp species. The deep-sea spongicolid species from the South China Sea is the firstreport. Further researches to the deep sea of the South Chinae Sea should find morespongicolid species.
