Several specimens in BMNH labelled as  G. hirundofrom Japanand Chinawere all observed by us (MB) and not confirmed as belonging to the present species. Two specimens in MMF collection previously identified by G. E. Maul as  G. hirundo, were reidentified by the authors as  G. altavela. Several authors questioned the validity of this species ( Compagno 1999; Wirtz et al. 2008; Eschmeyer et al. 2017; Yokota et al. 2016) and with further studies it may well be considered as a synonym of  G. altavela. Since no specimens of this species have been found in museum collections, we opt to place it as in need of confirmation. 1848580451 [151,975,1517,1545] Madeira 27 486 1 Madeira
