Allozyme products of 32 gene loci were compared for the North American cyprinid fishes Campostoma oligolepis, Cyprinella galactura, Cyprinella monacha, Erimystax cahni, E. dissimilis, E. insignis, E. x-punctatus, Hybopsis amblops, H. labrosa, H. rubriforns, H. zanema, Macrhybopsis aestivalis, M. gelida, M. meeki, Nocomis biguttatus, Phenacobius uranops, Platygobio gracilis, and P. storeriana. Triose-phosphate isomerase was found to be duplicated in all species examined. Parsimony analysis revealed that Hybopsis sensu lato did not form a monophyletic group. Cyprinella monacha was found to be the sister species to members of the genus Cyprinella and was excluded from the genus Erimystax. A clade of four species of Erimystax was identified although relationships among the four species could not be resolved. Phenacobius was identified as the sister group to Erimystax. The genus Macrhybopsis was expanded to include M. aestivalis. Macrhybopsis gelida was identified as the sister to M. meeki and M. aestivalis as the sister to the former two species. The genus Platygobio was expanded to include P. storeriana. Hybopsis labrosa and H. zanema were found to be more closely related to members of the genus Hybopsis sensu stricto than to members of Cyprinella.
对北美鲤科鱼类寡鳞坎氏鱼、半黄小鲤、单色小鲤、卡氏埃氏米诺鱼、歧异埃氏米诺鱼、显著埃氏米诺鱼、斑点埃氏米诺鱼、钝吻似鱥、唇似鱥、红鳍似鱥、赞氏似鱥、estivalis麦氏鱼、gelida麦氏鱼、meeki麦氏鱼、双线诺氏鱼、铀点叶唇鱼、细身扁丽鱼和斯氏扁丽鱼的32个基因位点的等位酶产物进行了比较。发现磷酸丙糖异构酶在所有检测的物种中都存在重复。简约分析表明,广义的似鱥属没有形成一个单系类群。发现单色小鲤是小鲤属成员的姐妹物种,并被排除在埃氏米诺鱼属之外。确定了一个由四种埃氏米诺鱼组成的进化枝,尽管这四个物种之间的关系无法确定。叶唇鱼属被确定为埃氏米诺鱼属的姐妹类群。麦氏鱼属扩大到包括estivalis麦氏鱼。gelida麦氏鱼被确定为meeki麦氏鱼的姐妹种,而estivalis麦氏鱼是前两个物种的姐妹种。扁丽鱼属扩大到包括斯氏扁丽鱼。发现唇似鱥和赞氏似鱥与狭义的似鱥属成员的关系比与小鲤属成员的关系更密切。
