在本文中，我们报告的第二个非土著种dreissenid贻贝在五大湖的发现和影响。这个物种被发现在一个常规的筛选斑马贻贝（Dreissena polymorpha）等位酶的变异。这两个物种不同的等位酶位点（内氏I = 0.30，使用12个位点），并在他们的壳形态（第二个物种缺乏锐角，或隆突，腹侧和背侧表面之间的斑马贻贝的壳）。 作为一个工作名称，至少在它的物种身份被发现之前，我们称这个新物种为“斑驴贻贝”。“目前，这种贻贝出现在安大略湖的频率与D。多形。它在邻近沃茨（例如伊利运河、尼亚加拉河和奥农达加湖的出口）中出现的频率较低，在其他任何五大湖中都没有出现，这表明：（1）它传入北美的地点是在安大略;（2）它的分布范围可能会扩大。
In this paper we report the discovery and implications of a second nonindigenous species of dreissenid mussel in the Great Lakes. This species was detected in a routine screening of zebra mussels (Dreissena polymorpha) for allozyme variability. The two species differ at allozyme loci (Nei's I = 0.30 using 12 loci) and in their shell morphology (the second species lacks the acute angle, or carina, between the ventral and dorsal surfaces of the shell of the zebra mussel). As a working name, at least until its species identity is discovered, we have called the new species the "quagga mussel." Currently, this mussel occurs in Lake Ontario in equal frequencies with D. polymorpha. Its low frequency of occurence in neighboring waters (e.g. the Erie canal, Niagara River, and outlet to Onondaga Lake) and lack of occurrence in any of the other Great Lakes suggest that (1) its point of introduction to North America was in Lake Ontario and (2) its range may expand.
