通过对线粒体编码的16S rRNA基因部分序列的分析，研究了来自日本南部沿海的两个广泛共域且形态相似的唇形虫种间的遗传差异。这两个种分别是Pseudolabus eoesinus(Richardson，1846)和P.sieboldi Mabuchi and Nakabo，1997年。对每个物种，代表三个种群的15个个体进行了测序。在eoesinus个体中，只有1个个体显示出序列差异，而P.siebotdi则发现了9个单倍型。以单倍型g：ymno.aenis(Gunther，1862)为外类群，用最大简约法和邻接法进行的系统发育分析表明，两个种是相互单系的。从2.9%到4.2`？“(平均3.3`X)，与PsettdolabrLts guentheri Bleeker，1862，P.Miles(Bioch and Schneider，1801)和R btSeralis(Krunzinger，1879)(2.9-3.6`X，)的结果相当，进一步证实了这两个种在日本的特殊地位。
Genetic differences between two widely sympatric and morphologically similar labrid species from the southern coasts of Japan, Pseudolabrus eoethinus (Richardson, 1846) and P. sieboldi Mabuchi and Nakabo, 1997, were investigated by examination of partial sequences of the mitochondrially-encoded 16S rRNA gene. For each species, 15 individuals representing three populations were sequenced. Among the individuals of P. eoethinus, only one showed evidence of a sequence difference, whereas nine haplotypes were found for P. siebotdi. Phylogenetic analyses using maximum parsimony and neighbor-joining methods, with a haplotype of g:ymno.aenis (GUnther, 1862) as an outgroup, showed of two species of Pseudotabrus are reciprocally monophyletic. from 2.9% to 4.2`?" (3.3`X, on average), such being comparable to those among the three congeneric species PsettdolabrLts guentheri Bleeker, 1862, P. miles (Bioch and Schneider, 1801). and R btserialis (Klunzinger, 1879) (2.9-3.6`X,); furthermore, these diD ferences corroborate the specific status of both of the species from Japan.
