Abstract

A new genus and species, Mauritiorchestia fayetta gen. nov., sp. nov., of talitrid amphipod is described from beaches in Mauritius. Mauritiorchestia differs significantly from the closely related genus Platorchestia in the maxilla 1 palp (absent in Mauritiorchestia, vestigial in Platorchestia) and in the dactylus of gnathopod 1 (simplidactylate in Mauritiorchestia, cuspidactylate in Platorchestia).

摘要

本文描述了来自毛里求斯海滩的一种新的等足目端足类生物，即毛里求斯胸刺属（Mauritiorchestia）的一个新属和新种，毛里求斯胸刺虾（Mauritiorchestia fayetta gen. nov., sp. nov.）。毛里求斯胸刺虾与亲缘关系密切的 Platorchestia 属在很大程度上不同，主要表现在第一大颚触须（毛里求斯胸刺虾中缺失，而在 Platorchestia 中为遗迹）和第一对颚足的指节（毛里求斯胸刺虾中简单，而在 Platorchestia 中为尖刺）。
