Abstract

We here report two new species of meiofaunal orbiniids belonging to the genus Questa Hartman, 1966, which have been discovered during benthic surveys conducted around the Azores and the Canary Islands. The new species, Q. manuelgerardi n. sp. and Questa ericnunezi n. sp., are described, figured and discussed in detail. Questa manuelgerardi n. sp., endemic from the Azores, is characterized by the lack of furcate chaetae and branchiae, and by the presence of two pairs of anal cirri. Questa ericnunezi endemic from the Canary Island, is defined by the presence of furcate chaetae, 12-18 pairs of branchiae, and two pairs of anal cirri. In addition, new records of the species Q. caudicirra Hartman, 1966 are provided. An identification key to the 12 known species of Questa is also included.

摘要

我们在此报告两种新的小型底栖多毛类动物，属于奎斯塔属（Questa Hartman，1966），它们是在亚速尔群岛和加那利群岛周围进行的底栖生物调查中发现的。对新物种曼努埃尔·热拉尔迪奎斯塔（Questa manuelgerardi n. sp.）和埃里克·努涅兹奎斯塔（Questa ericnunezi n. sp.）进行了详细描述、绘图并讨论。曼努埃尔·热拉尔迪奎斯塔（Questa manuelgerardi n. sp.）是亚速尔群岛特有的物种，其特征是没有分叉刚毛和鳃，有两对肛门触须。埃里克·努涅兹奎斯塔（Questa ericnunezi）是加那利群岛特有的物种，其特征是有分叉刚毛、12 - 18对鳃和两对肛门触须。此外，还提供了1966年哈特曼描述的尾触须奎斯塔（Q. caudicirra）物种的新记录。还包括了奎斯塔属12个已知物种的鉴定检索表。
