Taiwan voucher material: (11 spec.) NTUM 7234001 (holotype, D. tachiensis ), juvenile male 480 mm TL, 24°56.5' N, 121°53.0' E, 3000 m off coast of Da-xi, north-eastern Taiwan, 200–240 m depth; ASIZP 58674, 406 mm TL, Da-xi, 15 Sep 1997 ; ASIZP 60559, 413 mm TL, Da-xi, 10 Feb 1997 ; ASIZP 62455, 419 mm TL, Da-xi, 8 Apr 2003 ; ASIZP 63278 , ASIZP 64621 , 1000 mm SL, Da-xi, 22 Feb 2003 ; CSIRO H 6292-09 , juvenile male 414 mm TL, Da-xi, 21 May 2005 ; FRIP 0340 (2 spec.), 345–365 mm TL, Dong-gang, 4 Oct 1957 ; UF 159698, juvenile female 366 mm TL, Da-xi , 25 May 2005 ; NMMB-P 15468 , Da-xi, 23 Oct 2011 .

Remarks: Shen & Ting (1972) described D. tachiensis based on a neonate of D. licha . One of us ( DAE, April 1988) examined the holotype of D. tachiensis and confirmed that it is a junior synonym of D. licha . This species is very common at fish markets around Taiwan, especially Da-xi, where deep-sea fisheries occur.

Conservation status: Near Threatened.
