ソトイワシ科魚類マルクチソトイワシ (新称) Albula glossodontaの日本からの記録

抄録

A single specimen (IORD 76-1074, 287 mm in standard length) of an albulid fish, Albula glossodonta (Forssk51), collected by bottom gill net from Iriomote Island, Okinawa Prefecture, represents the first reliable record from Japan and the northernmost record of the species. Albula glossodonta is herein re-described and given a new Japanese name, “marukuchi-sotoiwashi.” The species is readily distinguishable from A. forsteri, previously known from Japan, as follows: anteriormost outline of lower jaw broadly rounded (vs. angular in the latter), shorter upper jaw length [2.8-3.3 (mean 3.1) times in head length vs. 2.6-2.9 (mean 2.8)] and molariform tooth plates in the oral cavity more broadly oval in shape (vs. more elongate).
