A new pineapple fish is described based on 26 type and 80 non-type specimens collected from Taiwan, Vanuatu, the Solomon Islands, and Queensland, Australia. This new species is sympatric with and similar to Monocentris japonica but can be distinguished from the latter in having only 6 or 7 scales on the third scale row below the lateral line; excisura notched and a small pseudo-excisura present on the sagittal otolith; consistently greater head depth, body depth, postorbital length, dorsal-fin-pelvic-fin length, and dorsal-fin-pectoral-fin length in proportion to standard length. A detailed description and designation of neotype are provided for M. japonica. DNA barcoding analysis supports the distinction of the new species with an estimated average COI gene divergence of 3.6 % from M. japonica.
基于从台湾、瓦努阿图、所罗门群岛和澳大利亚昆士兰采集的26个模式标本和80个非模式标本，描述了一种新的凤梨鱼。这种新物种与日本单角鲀同域分布且相似，但可通过以下特征与后者区分开来：在侧线下方的第三排鳞片上只有6或7枚鳞片；矢耳石上有缺刻的切口和一个小的假切口；相对于标准体长，头部深度、体深、眶后长度、背鳍-臀鳍长度和背鳍-胸鳍长度始终更大。为日本单角鲀提供了详细描述和新模的指定。DNA条形码分析支持新物种的区分，估计其细胞色素氧化酶亚基I（COI）基因与日本单角鲀的平均分歧为3.6%。
