Abstract The Early Cretaceous mydid genus and species Cretomydas santanensis is revised on the basis of a new specimen, allowing to precise its relationships within the ‘advanced Mydidae’, probably close to the subfamily Diochlistinae. This extant group has a ‘Gondwanan’ distribution, known from Southern South America and Australia. The presence of an ‘advanced Mydidae’ during the Early Cretaceous also suggests a greater antiquity for this family.

早白垩世 mydid Cretomydas santanensis（双翅目：Mydidae）的修订

摘要 早白垩世 mydid 属和种 Cretomydas santanensis 在一个新标本的基础上进行了修订，可以精确地确定其在可能与 Diochlistinae 亚科接近的“高级 Mydidae”中的关系。这个现存的群体有一个'冈瓦纳'分布，在南美洲南部和澳大利亚已知。在白垩纪早期出现的“高级Mydidae”也表明这个家族更古老。
