1802年，在日本南部的琉球群岛石垣岛采集到一个Ostorhinchus Lacepède属的标本（标准长度为39.1毫米），经鉴定为Ostorhinchus hartzfeldii（Bleeker，1852）。该种的特征性体色包括：头和体上有4条略呈波浪状的纵向银纹，最后一条沿着体背缘延伸至尾鳍基部，其余几条终止于躯干或尾梗;尾鳍基部的黑点，大小与瞳孔相似。哈氏Ostorhinchus hartzfeldii与库克Ostorhinchus cookii相似（Macleay，1881），Ostorhinchus nigrofasciatus（Lachner，1953），和Ostorhinchus taeniophorus（里根，1908年），但与它们不同的是，只有最背的纵向银线到达尾鳍基部（与其他三个物种的三个或四个线到达鳍基）和缺乏纵向银线的腹外侧方面的躯干（vs. present）. Hartzfeldii分布于西太平洋，从南中国海到澳大利亚，但以前没有在日本沃茨的记录。本书还收录了石垣岛物种的照片记录。新的标准日本名称"Sazanami-ishimochi"是根据从石垣岛采集的标本提出的，它指的是随着生长而消失的轻微波浪状银线。
A specimen (39.1 mm standard length) of the genus Ostorhinchus Lacepède, 1802, collected from Ishigaki-jima Island, the Ryukyu Archipelago, southern Japan, was identified as Ostorhinchus hartzfeldii (Bleeker, 1852). The specimen showed characteristic coloration of the species, including the following features: four slightly wavy longitudinal silver lines on the head and body, the dorsalmost running along the dorsal body margin to the caudal fin base, and the others terminating on the trunk or caudal peduncle; the entire body base color brown; all fins slightly reddish, transparent; a dark spot on the caudal fin base, of similar size to the pupil. Ostorhinchus hartzfeldii is similar to Ostorhinchus cookii (Macleay, 1881), Ostorhinchus nigrofasciatus (Lachner, 1953), and Ostorhinchus taeniophorus (Regan, 1908), but differs from them by having only the dorsalmost longitudinal silver line reaching the caudal fin base (vs. three or four lines reaching the fin base in the other three species) and absence of a longitudinal silver line on the ventrolateral aspect of the trunk (vs. present). Ostorhinchus hartzfeldii is distributed in the western Pacific, from the South China Sea to Australia, but had not previously been recorded from Japanese waters. A photographic record of the species from Ishigaki-jima Island is also included. The new standard Japanese name “Sazanami-ishimochi” is proposed, a reference to the slightly wavy silver lines that disappear with growth, based on the specimen collected from Ishigaki-jima Island.
