Paratanais rosadi
sp. n. described from Puerto Rican coastal waters represents the first species of the genus from the northwestern Atlantic. It is distinguished from the other Paratanais species by a combination of characters, including article-2 of the maxilliped palp with a geniculate, finely-serrulate seta on inner margin; chela with stiff, geniculate, seta arising from propodus between fixed finger and dactylus and with short, stout, finely serrulate, seta on inner distal face of propodus adjacent to base of dactylus; carpus of pereopods 4−6 having three, instead of four stout modified spiniform setae distally, uropodal exopod distinctly shorter than endopodal article-1; and uropodal endopod with articles of about of equal in length. A key for the separation of Paratanais species from the Atlantic Ocean is presented. 相似文献

Three new species of are described from the manganese nodule province between the Clarion and the Clipperton Fracture Zone of the equatorial North Pacific Ocean, and collected during the Nodinaut expedition on board the r/v l′Atalante in the summer of 2004. The new species belongs to three genera as: Collettea (Collettea longisetosa), Robustochelia (Robustochelia pacifica), and Tumidochelia (Tumidochelia tuberculata). A key to the genus Tumidochelia is presented and the validity of the genera Robustochelia and Collettea is discussed. 相似文献
