根据形态学和分子生物学特征（COI和28 S）对西太平洋（包括南海）沿着的4种沿岸的尖扁壳藻（Phucobius Sharp）进行了分类学上的重新鉴定。四种标本的地理分布各不相同，但包括伊蚊的中叶结构在内，都极为相似，可视为同种。此外，分子生物学分析支持P. pectoralis与基于形态特征的三个同义词的有效性。用未校正的p-距离法计算的各物种间COI的遗传分化率为0.11%~ 3.21%。三个不同的地理集群（俄罗斯，韩国和日本，越南）被发现在新泽西州和PA的树木，我们把所有这些作为一个单一的物种。本文提出了三个新的同物异名：P. simulator Sharp syn.十一月，三色堇十一月，和密翅拟青霉P. densipennis Bernhauer syn. nov. Phucobius pectoralis是重新描述与诊断字符的插图。此外，还简要讨论了种内种群间的变异。
A taxonomic reappraisal of four marine littoral Phucobius Sharp species along the western Pacific Ocean including the South China Sea is presented based on morphological and molecular characters (COI and 28S). Specimens of the four species, each having its own distinct geographic distribution, are extremely similar to each other including the structures of the median lobe of the aedeagus, and may be regarded as conspecific. Also, the molecular analyses support the validity of P. pectoralis with three synonymies based on morphological characters. Genetic divergence of COI using uncorrected p-distance among all individuals of Phucobius species ranged from 0.11% to 3.21%. Three distinct geographical clusters (Russia, Korea and Japan, and Vietnam) are found in the NJ and PA trees and we treat all of them as a single species. Three new synonyms are proposed for Phucobius pectoralis (Boheman): P. simulator Sharp syn. nov., P. tricolor Bernhauer syn. nov., and P. densipennis Bernhauer syn. nov. Phucobius pectoralis is redescribed with illustrations of diagnostic characters. Also, the intraspecific variation among the populations of P. pectoralis is briefly discussed.
