Abstract

The combtooth blenny (Blenniidae) genus Omobranchus contains small, cryptobenthic fishes common to nearshore habitats throughout the Indo-West Pacific. Recent molecular systematic studies have resolved Omobranchus as monophyletic but little research has been done to resolve species-level relationships. Herein, phylogenetic analyses of one mitochondrial (CO1) and four nuclear (ENC1, myh6, sreb2, and tbr1) genes provide evidence for the monophyly of Omobranchus and support for the elongatus and banditus species group. Sampling of multiple individuals from widespread species (O. ferox, O. punctatus, and O. elongatus) suggested that the Thai-Malay Peninsula is a phylogeographic break that may be a historic barrier to gene flow. Additionally, common meristics and other morphological characters are used to describe an early life history stage of O. ferox and O. punctatus.

摘要

梳齿鳚属（Omobranchus）的梳齿鳚（Blenniidae）包含小型的隐栖性鱼类，常见于印度-西太平洋的近岸栖息地。最近的分子系统学研究已确定梳齿鳚属为单系类群，但在解决物种水平的关系方面所做的研究很少。在此，对一个线粒体基因（CO1）和四个核基因（ENC1、myh6、sreb2和tbr1）进行系统发育分析，为梳齿鳚属的单系性提供了证据，并支持长体梳齿鳚和带纹梳齿鳚物种组。对广泛分布的物种（凶猛梳齿鳚、斑点梳齿鳚和长体梳齿鳚）的多个个体进行采样表明，泰国-马来半岛是一个系统发育地理断点，可能是基因流动的历史障碍。此外，还使用常见的可数性状和其他形态特征来描述凶猛梳齿鳚和斑点梳齿鳚的早期生活史阶段。
