West African species of ScyllarusFabricius, 1775 (Achelata, Scyllaridae) are poorly known, mostly due to the difficulties of sampling Eastern Atlantic tropical waters. Recent expeditions carried out by the Universidad de Cádiz and the Instituto Español de Oceanografía collected phyllosoma larvae from Cape Verde Islands (CVI) and fresh Scyllarus adults from continental West Africa. Larval stages VII, IX, and X (final stage) of S. capartiHolthuis, 1952 are analyzed using DNA barcoding methods and described for the first time. A comprehensive identification key is provided, summarizing our current knowledge on the phyllosomas of Scyllarus. Together with a revision of museum collections, the new molecular and morphological data obtained here supports the polyphyletic origin of AcantharctusHolthuis, 2002. The West African A. posteli (Forest, 1963) is found to belong to Scyllarus and it is closest to another species from Atlantic shallow waters (i.e. S. paradoxusMiers 1881), whereas the Pacific Ocean A. delfini (Bouvier, 1909) would belong to CrenarctusHolthuis, 2002.

修订1775年的西非Scyllarus Fabricius物种(十足目:Achelata:Scyllaridae),并描述了S. caparti Holthuis的三个叶绿体阶段,1952年和更新的识别码

西非希拉勒Fabricius,1775年(Achelata,Scylaridae)知之甚少,主要是由于难以对东部大西洋热带水域进行采样。加的斯大学和海洋科学研究所最近进行的考察收集了佛得角群岛(CVI)的phyllosoma幼虫和西非大陆的新鲜Scyllarus成虫。卡氏链球菌的幼虫阶段VII,IX和X(最终阶段)Holthuis,1952年使用DNA条形码方法进行了分析,并首次进行了描述。提供了一个全面的识别码,总结了我们目前对锡兰毛孔瘤的认识。连同博物馆收藏的修订版,此处获得的新分子和形态学数据支持了棘叶c的多系起源。Holthuis,2002年。西非A. posteli森林(1963)被发现属于Scyllarus,它与大西洋浅水区的另一物种(S. paradoxus)最接近Miers 1881),而太平洋A. delfiniBouvier,1909年),属于CrenarctusHolthuis,2002年。
