玻璃虾总科系统分类学研究概况及我国玻璃虾总科研究展望

玻璃虾总科隶属于甲壳动物亚门十足目,真虾下目,生物多样性高,形态和栖息环境变化大,世界性海洋分布,从潮下带到千米深海,从极地到赤道海域均有发现,动物地理学特征显著。该总科物种是海洋生态系统和生物群落的重要组成部分,具有重要的生态学和生物多样性价值;是研究真虾类起源与进化的重要阶元;部分物种更是传统渔业捕捞对象。然而该总科也是真虾下目中缺乏系统研究的类群,其生物多样性和分类学研究不完善,所含很多阶元的单系性受到质疑,同物异名等问题突出,更有许多非正式种组有待修订。我国海域玻璃虾总科的生物多样性研究更是匮乏,其种属组成,海域分布,区系特点等鲜为人知。未来可在收集和掌握大量文献与标本的基础上,以形态分类学为基础,结合现代分子系统学和生物地理学,研究其在中国海的种属组成,资源分布和区系特点,进而系统研究其动物地理学特征。

Introduction and prospect of a systematic study of the superfamily Pasiphaeoidea in China

Pasiphaeoidea Dana, 1852 is a speciose group with a high diversity of morphological specificity and living habitats of Caridea, Decapoda, and Crustacea. Pasiphaeoidean shrimps are distributed throughout oceans worldwide, from coastline to bathypelagic habitats, and are even present in polar seas, with remarkable zoological distributions. They are important components of the mesopelagic and benthopelagic communities in the marine ecosystem, with great significance for ecology, biodiversity, and systematic studies; some of them are very important economic species. However, systematic research on this superfamily is lacking compared to that on other superfamilies within Caridea. There are many long-standing issues in pasiphaeoidean taxonomy awaiting revision, including the monophyletic nature of some taxa, synonyms, informal species groups. The biodiversity, taxonomy, and fauna of Chinese pasiphaeoideans are not well studied either with respect to scattered reports of occurrences of species from China seas or categories only listed in the literature. The species compositions and zoogeographic features of Chinese fauna are almost unknown. In the future, based on abundant specimens and plentiful literature, the biodiversity and taxonomic study of pasiphaeoideans by means of morphological classification, molecular phylogenetic analysis, and zoogeographical research will uncover the detailed species-genus compositions, distributions, and faunistic characters of Chinese pasiphaeoidean shrimps, and subsequently, explore the origin, evolution, and migration pattern of their fauna.
