The surfperch genus Embiotoca currently comprises two species, Embiotoca jacksoni, the black surfperch, and Embiotoca lateralis, the striped surfperch. Originally, however, Louis Agassiz described a third species in the genus Embiotoca, the rainbow surfperch, Embiotoca caryi. This latter name was changed by Louis' son, Alexander, to Hypsurus caryi, a name that remains valid. In this study, new molecular data (3545 bp of DNA from four mitochondrial and two nuclear DNA regions) indicated that the rainbow surfperch should be retained within the genus Embiotoca, a result consistent with recent morphological data. Adaptive radiation combined with sexual selection resulting in rapid morphological changes in the rainbow surfperch may have contributed to the conflicting position of this species.
目前，鲈形目拟雀鲷属包括两个物种，黑拟雀鲷（Embiotoca jacksoni）和条纹拟雀鲷（Embiotoca lateralis）。然而，最初路易斯·阿加西（Louis Agassiz）在拟雀鲷属中描述了第三个物种，虹彩拟雀鲷（Embiotoca caryi）。这个后一个名字后来被路易斯的儿子亚历山大（Alexander）改为 Hypsurus caryi，这个名字仍然有效。在这项研究中，新的分子数据（来自四个线粒体和两个核 DNA 区域的 3545 个碱基对的 DNA）表明，虹彩拟雀鲷应保留在拟雀鲷属内，这一结果与最近的形态学数据一致。适应辐射加上性选择导致虹彩拟雀鲷的快速形态变化，可能导致了该物种的矛盾地位。
