Podotremata is a traditionally used section of crabs (Brachyura), now considered to be invalid. It was the smaller grouping of crabs, separate from the larger Eubrachyura section. Morphological and molecular analyses do not reveal a monophyletic Podotremata, but rather that it is paraphyletic, and so the most recent classifications divide "Podotremata" into three sections: Dromiacea, Cyclodorippoidea and Raninoida.[1][2]
This group contains the following superfamilies (with their current sections indicated in parentheses):
Here is a cladogram showing the placement of the former members of Podetremata (highlighted in bold) within Brachyura:[3][2]

肢孔派（Podotremata）是部份分類學系統在短尾次目（Brachyura，亦作短尾下目）旗下的一個小型的組別，其成員在螃蟹各物種被視為「低等蟹類」[1]:7[2]（即其後1-2對步足已退化或特化）[3]:i。Grave et al. (2009)依從Martin & Davis (2001)的建議，認為無論從形態學及分子生物學分析都無法確認肢孔派物種乃單系群，所以將本分類的五個總科劃分為三個不同的派[1]:7：
這些分類的關係如下[4]：
