ON THE IDENTITIES OF PILUMNOPEUS CONVEXUS MACCAGNO, 1936, AND P. SALOMONENSIS WARD, 1942, FROM THE INDIAN OCEAN, WITH A NOTE ON P. RIUI TAKEDA, 2001 (DECAPODA, BRACHYURA, PILUMNIDAE)

摘要

The taxonomy of the western Indian Ocean pilumnid crab, Pilumnopeus convexus (Maccagno, 1936) (type locality: Ethiopia) is discussed and the poorly known P. salomonensis Ward, 1942 (type locality: Chagos Archipelago) is shown to be its junior synonym. Pilumnopeus sinensis Balss, 1933 (from China) is transferred to Serenepilumnus Turkay & Schumacher, 1985. Pilumnopeus riui Takeda, 2001 (from Hainan) is herein synonymized with Aniptumnus quadridentatus (De Man, 1895). Pilumnopeus ? laevimanus Cano, 1889 (from South America) is removed from the genus; it is more likely to be a species of Panopeidae or Pseudorhombilidae.
