自20世纪90年代以来，人们一直推测淡水端足类Hyalella Azteca(Sausure，1858)的不同种群/大小类别是不同的物种，后来出现了大量的遗传证据，证实它实际上是一个神秘的物种复合体。然而，自那以后，美国东部或加拿大再也没有描述过Hyalella的新物种。在此，我们描述了两个新种，Hyalella(Hyalella)Spinicauda和Hyalella(Hyalella)well borni，它们采集自美国伊利诺伊州、印第安纳州、密歇根州、威斯康星州、德克萨斯州和加拿大安大略省，基于形态特征，但通过遗传分析获得信息。此外，我们还提供了北美和加勒比地区所描述的Hyalella种类的最新检索表。
Since the 1990s, it has been presumed that different populations/size classes of the freshwater amphipod Hyalella azteca (Saussure, 1858) were different species, and a multitude of genetic evidence was later produced to confirm that it is in fact a cryptic species complex. However, no new species of Hyalella have been described from the eastern United States or Canada since then. Herein we describe two new species, Hyalella ( Hyalella ) spinicauda and Hyalella ( Hyalella ) wellborni , collected from Illinois, Indiana, Michigan, Wisconsin, and Texas, USA, and Ontario, Canada, based on morphological characters but informed by genetic analyses. In addition, we provide an updated key to the described species of Hyalella in North America and the Caribbean.
