Members of several genera in the digenean superfamily Microphalloidea, namely , , , and , are characterized by an unusual dorsal position of the genital atrium. In the absence of phylogenetic data, their systematic position has been unstable. In the most recent taxonomic revision of the Microphalloidea, they were housed in three different families. We studied the morphology and obtained DNA sequences of several microphallolideans with a dorsal genital pore, collected from vertebrates in Southeast Asia and South America. We used sequences of the nuclear 28S gene to infer a superfamily-level phylogeny and sequences of the mitochondrial gene for family-level phylogeny and species-level comparisons. Based on the combination of molecular phylogenetic data and morphological features, we restore the Cryptotropidae and synonymize the Renschetrematidae with the Cryptotropidae. We erect new genera and , provide amended diagnoses of the Cryptotropidae and and provide keys to the identification of genera within the family. We resurrect the genus , previously synonymized with , and remove from . We describe four new species from lizards in Vietnam and birds in the Philippines and Peru. The unique morphological features and unusually broad host associations and geographical distributions of cryptotropids are discussed.
复殖亚纲微杯科几个属的成员，即[此处原文未给出具体属名]、[此处原文未给出具体属名]、[此处原文未给出具体属名]、[此处原文未给出具体属名]和[此处原文未给出具体属名]，其特征为生殖腔处于异常的背侧位置。由于缺乏系统发育数据，它们的系统位置一直不稳定。在微杯科最新的分类修订中，它们被归入三个不同的科。我们研究了从东南亚和南美洲的脊椎动物中采集的几种具有背侧生殖孔的微杯科吸虫的形态，并获取了其DNA序列。我们使用核28S基因序列推断超科级系统发育，使用线粒体[此处原文未给出具体基因名]基因序列进行科级系统发育和种级比较。基于分子系统发育数据和形态特征的结合，我们恢复了隐穴科，并将雷氏吸虫科与隐穴科同义化。我们建立了新属[此处原文未给出具体属名]和[此处原文未给出具体属名]，提供了隐穴科和[此处原文未给出具体科名]的修订诊断，并提供了该科内属的鉴定检索表。我们复活了之前与[此处原文未给出具体属名]同义的[此处原文未给出具体属名]属，并将[此处原文未给出具体属名]从[此处原文未给出具体属名]中移除。我们描述了来自越南蜥蜴以及菲律宾和秘鲁鸟类的四个新物种。讨论了隐穴科吸虫独特的形态特征、异常广泛的宿主关联和地理分布。
