Taiwan voucher material: (4 spec.) NMMB-P 6434-1 (1 of 2 spec.) , NMMB-P 6441 , Wu-Chi, Taichong, 20 Apr 1962 ; NMMB-P 6453-1 (1 of 2 spec.), Taichong, 22 Feb 1962 ; NMMB-P 6455 , Taichong, 8 May 1962 .

Remarks: TFRI uncatalogued, Kaohsiung, caught off Liuchiu Island, examined and photographed by DAE 29 Apr 1988. Not particularly common in fisheries landings in Taiwanese waters. DAE examined and photographed a specimen at the TFRI, Kaohsiung that had been caught off Liuchiu Island. Negogaleus brachygnathus Chu, 1960 , described from off Yinge Hai in China, is a junior synonym of this species. Appears to be naturally low in abundance where it occurs and possibly rare in Taiwanese waters presently.

Conservation status: Vulnerable.
