| description | It is unreliable to identify marine fishes only by external morphological features. Species misidentification brings great challenges to fishery research, resource monitoring and ecomanagement. <i>Sillago ingenuua</i> is an important part of commercial marine fishes, and in which, the morphological differences between different groups are not obvious. Here, we compared different geographical groups of <i>S. ingenuua</i> which were collected from Xiamen, Dongshan, Keelung, Songkhla and Java. The results showed that all samples of <i>S. ingenuua</i> were similar in external morphological characteristics and the shape of the swim bladder, but there were two distinctive lineages which were flagged as cryptic species based on DNA barcoding. The comparative mitogenomic results showed that <i>S. ingenuua</i> A and <i>S. ingenuua</i> B were identical in structural organization and gene arrangement. Their nucleotide composition and codon usage were also similar. A phylogenetic analysis was performed based on 13 concatenated PCGs from eight <i>Sillago</i> species. The results showed that the genetic distance between <i>S. ingenuua</i> A and <i>S. ingenuua</i> B was large (D = 0.069), and this genetic distance was large enough to reveal that <i>S. ingenuua</i> A and <i>S. ingenuua</i> B might be different species. |
