摘要

摘要根据从印度西南海岸的垃圾鱼中收集到的未知寄主的雌卵，描述了一种新的鳃鱼寄生卵状体，Elthusa aquabio sp. n.(甲壳纲:等足纲:卵状体科)。水生Elthusa aquabio sp. 11 .具有以下特点:(1)体微扭曲，伸长，背面光滑，是最大宽度的1.8倍;(2) pleon短，为体长的0.16倍，pleon宽为体长最大宽度的0.75倍;(3)在pleonite 3处最宽，在pleonite 1处最窄;(4)髋部5-7，平，宽，横向展开;(5)尾足是肢端长度的0.7倍;准足类1-3似足类的内侧缘具小的，粗壮的刺;(7) 10条天线。http://www.zoobank.org/urn:lsid:zoobank.org:pub:60365DA9-9DD1-449F-B81F-30250B6E644D

Description of Elthusa aquabio sp. n. (Crustacea: Isopoda: Cymothoidae), a branchial fish parasitic isopod from Indian waters

ABSTRACT A new branchial fish parasitic cymothoid species, Elthusa aquabio sp. n. (Crustacea: Isopoda: Cymothoidae), is described based on the ovigerous female collected from an unknown host obtained from trash fishes from the south-west coast of India. The species Elthusa aquabio sp. nov. has the following characteristics: (1) body slightly twisted, elongated, dorsal surfaces smooth, 1.8 times as long as greatest width; (2) pleon short, 0.16 times as long as total body length, pleon 0.75 times as wide as pereion maximum width; (3) widest at pleonite 3 and most narrow at pleonite 1; (4) coxae 5–7, flat, broad, laterally expanded; (5) uropods 0.7 times as the length of pleotelson; (6) pereopods 1–3 propodus inner lateral margin with small, robust spines; (7) antenna with 10 articles. http://www.zoobank.org/urn:lsid:zoobank.org:pub:60365DA9-9DD1-449F-B81F-30250B6E644D

期刊介绍： Journal of Natural History is an international zoological journal publishing original research and reviews in evolutionary biology and ecology. It maintains its historical niche by publishing a broad range of systematics papers on all animal phyla from Porifera to Chordata, encompassing traditional taxonomic revisions and descriptions, cladistic analyses and molecular phylogenetics and phylogenomics. The journal has recognized strengths in entomology and marine invertebrates, but also welcomes papers on the natural history of all animal species and on the interactions of species with their environment. Preference is given to in-depth papers and extensive taxonomic reviews: single species descriptions and checklists are not normally considered. Authors wishing to suggest a review paper should contact the relevant editor.
