A new Portholefish, Diplophos vicinia sp. nov., is described on the basis of nine specimens collected from the western Pacific Ocean by commercial midwater trawl. The new species, currently known only from the South China Sea and north of Papua New Guinea, can be easily distinguished from six nominal congeners by the combination of the following characters: dorsal-fin origin closer to snout than caudal-fin base, distance between last two AC photophores half that between preceding photophores, gill rakers 4 + 10-11=14-15, abdominal vertebrae 30-32, caudal vertebrae 44-45, total vertebrae 74-76, and the following photophore counts: IP 13-14, PV 18-19, IV 31-32, VAV 12-13, AC 37-39 + 2, and IC 83-86.
基于通过商业中层拖网从西太平洋采集的9个标本，描述了一种新的孔头鱼——近邻双光鱼（Diplophos vicinia sp. nov.）。该新物种目前仅在南海和巴布亚新几内亚以北被发现，通过以下特征组合可轻易与六个同属已知物种区分开来：背鳍起点距吻部比距尾鳍基部更近，最后两个AC发光器之间的距离是前一个发光器之间距离的一半，鳃耙4 + 10 - 11 = 14 - 15，腹椎30 - 32个，尾椎44 - 45个，总椎骨74 - 76个，以及以下发光器数量：IP 13 - 14个，PV 18 - 19个，IV 31 - 32个，VAV 12 - 13个，AC 37 - 39 + 2个，IC 83 - 86个。
