葡萄牙沃茨动吻类小型底栖动物的首次调查发现，在该海域存在两种未描述的环虫属棘水蚤。本文描述了卢西坦棘皮绦虫Echinoderes lusitanicus sp. nov.和赖氏棘皮绦虫Echinoderes reicherti sp. nov.，两者都是从葡萄牙最南端的阿尔加维海岸的潮下带地区采集的。lusitanicus sp. nov.的管节2上的亚背侧和腹外侧的位置，节5上的侧腹位置，节8上的侧附属位置，和节10上的侧背位置的存在被确认。棘出现在第4节至第8节的背中位置，以及第8节和第9节的腹侧位置。雌性有微小的侧端附属刺。第二个种E. reicherti sp. nov.，其特征在于，在背侧和腹外侧位置的节2上，在腹侧位置的节5上，以及在近侧位置的节8上的管。此外，该物种在第4节的中背位置和第6至9节的侧腹位置具有针状刺。形态方面，如管/刺模式的躯干或性二型性状进行了讨论，并与其他Echinoderes物种表现出密切的相似性。http://zoobank.org/urn:lsid:zoobank.org:pub:79C25EEE-9064-46F8-95E2-EE493DC82185
ABSTRACT The first exploration of the kinorhynch meiofauna in Portuguese marine waters has revealed the existence of two undescribed species of the cyclorhagid genus Echinoderes. In the present contribution we describe Echinoderes lusitanicus sp. nov. and Echinoderes reicherti sp. nov., both collected from subtidal regions of the coast of Algarve in the southernmost region of Portugal. Echinoderes lusitanicus sp. nov. is recognized by the presence of tubes on segment 2 in subdorsal and ventrolateral positions, on segment 5 in lateroventral positions, on segment 8 in lateral accessory positions, and on segment 10 in laterodorsal positions. Spines are present in middorsal position on segments 4 to 8, and in lateroventral positions on segments 8 and 9. The females have minute lateral terminal accessory spines. The second species, E. reicherti sp. nov., is characterized by tubes on segment 2 in subdorsal and ventrolateral positions, on segment 5 in lateroventral positions, and segment 8 in sublateral positions. In addition, the species possesses acicular spines in the middorsal position on segment 4, and in lateroventral positions on segments 6 to 9. Morphological aspects such as tube/spine pattern of the trunk or sexually dimorphic traits are discussed and compared with other Echinoderes species showing close resemblance. http://zoobank.org/urn:lsid:zoobank.org:pub:79C25EEE-9064-46F8-95E2-EE493DC82185
