Mitochondrial DNA A DNA Mapp Seq Anal. 2017 Jul;28(4):584-587. doi: 10.3109/24701394.2016.1143470. Epub 2016 Feb 25.
The study attempted identification of Gobiid fishes from freshwaters in the east and northeast India on a collection of 20 specimens. The DNA barcode data delineated the collected samples into three species clades in the neighbor-joining tree. The results confirmed the identification of five sample sequences belonging to the subfamily Gobionellinae due to cohesive cladding with Awaous congeners. This is a new subfamily record for the northeastern region. Another 15 sample sequences showed conspecific cladding with Glossogobius giuris in the database. Among the 15 sample sequences, 14 sequences cladded with G. giuris sequences of Indian specimens while one sample sequence cladded with G. giuris sequences of South African specimens. This indicated the presence of either a hidden species or a previously synonymized species in the G. giuris complex.
该研究试图依据20个标本的采集来鉴定印度东部和东北部淡水中的虾虎鱼。DNA条形码数据在邻接树中将采集的样本划分为三个物种分支。结果证实，由于与阿胡虾虎鱼属同属生物具有紧密的分支关系，鉴定出五个属于戈氏虾虎鱼亚科的样本序列。这是东北地区新的亚科记录。另外15个样本序列在数据库中与睛斑舌虾虎鱼显示出同种分支关系。在这15个样本序列中，14个序列与印度标本的睛斑舌虾虎鱼序列分支在一起，而一个样本序列与南非标本的睛斑舌虾虎鱼序列分支在一起。这表明睛斑舌虾虎鱼复合体中存在一个隐藏物种或一个先前被归为同义词的物种。
