本文记述了海龙属一新种，海龙海龙Syngnathus chihiroe sp. nov.根据日本南部屋久岛（东中国海）外160-162米深处采集的一个标本描述了海龙科（Syngnathidae）的一种新属。根据以下特征的组合，该新种与所有同类很容易区分：背鳍条38条，胸鳍条17条，躯干环18条，尾环40条，背下环3.25+ 10.0= 13.25，头长8.7（标准长），吻长2.3（头长），吻深3.7（吻长）。新种与西北太平洋唯一的同类Syngnathus schlegeli Kaup 1853相似，其特征是背鳍条30-47，躯干环18-20和尾环38-46。但它不同于S。Schlegeli的胸鳍条数量较多（前者为17条，后者为11-15条），吻部较短，吻部较深（吻部长度为2.3，吻部深度为3.7，前者为1.6-2.0，后者为5.6-11.3）。
A new species of pipefish, Syngnathus chihiroe sp. nov.,(Syngnathidae), is described on the basis of a single specimen collected off Yakushima Island (East China Sea), southern Japan in a depth of 160-162 m. The new species is readily distinguished from all congeners by the combination of the following characters: dorsal-fin rays 38, pectoral-fin rays 17, trunk rings 18, tail rings 40, subdorsal rings 3.25+ 10.0= 13.25, head length 8.7 in standard length, snout length 2.3 in head length and snout depth 3.7 in snout length. The new species is similar to Syngnathus schlegeli Kaup 1853, the only other northwestern Pacific Ocean congener, characterized by dorsal-fin rays 30-47, trunk rings 18-20 and tail rings 38-46. However, it differs from S. schlegeli in having a greater number of pectoral-fin rays (17 in the former vs. 11-15 in the latter), and a short deep snout (snout length 2.3 in head length and snout depth 3.7 in snout length vs. 1.6-2.0 and 5.6-11.3, respectively).
