We describe two new genera of Triassic Aviculopectinoidea: Cristaflabellum n. gen., which is biconvex and has a strongly plicate shell, and Globodiscus n. gen., which is equiconvex and externally smooth or nearly so. Globodiscus contains the new species G. kiliani n. gen. n. sp. and G. vinzenti n. gen. n. sp. In order to make the taxonomic concept of the superfamily Aviculopectinoidea more consistent with that of its sister group Pectinoidea (scallops), we use tribes rather than families or subfamilies for accommodating the new taxa. Cristaflabellum is placed in the tribe Antijanirini (previously family Antijaniridae), whereas Globodiscus is made the type genus of the new tribe Globodiscini. Both tribes are placed within the family Aviculopectinidae, which is revised to include both equiconvex and inequiconvex taxa. We suggest that tribes are a more appropriate taxonomic rank for many of the previously erected species-poor families and subfamilies of Aviculopectinoidea.UUID: http://zoobank.org/d143663a-9016-459f-8e24-660102adcf6a

新的三叠纪 Aviculopectinoidea (Bivalvia),附有关于超科分类概念的注释

我们描述了三叠纪 Aviculopectinoidea 的两个新属:鲫鱼n. gen.,它是双凸面的,具有强烈的褶皱壳,并且环球铁饼n. gen.,它是等凸的,外部光滑或几乎如此。环球铁饼包含新物种G.基利亚尼n. 将军 n. sp。和G.文岑蒂n. 将军 n. sp。为了使 Aviculopectinoidea 超科的分类概念与其姊妹组 Pectinoidea(扇贝)的分类概念更加一致,我们使用部落而不是家庭或亚科来容纳新的分类群。鲫鱼被放置在 Antijanirini 部落(以前的 Antijaniridae 家族)中,而环球铁饼被制成新部落Globodiscini的模式属。这两个部落都属于 Aviculopectinidae 家族,该家族被修改为包括等凸和不等凸分类群。我们建议对于许多以前建立的 Aviculopectinoidea.UUID 的物种贫乏科和亚科,部落是更合适的分类等级:http://zoobank.org/d143663a-9016-459f-8e24-660102adcf6a
