Baissid wasps (Hymenoptera: Baissidae) represent a family within the superfamily Evanioidea composed of 36 species in seven genera restricted to a period spanning from the Berriasian (earliest Cretaceous) to the Turonian (early Late Cretaceous). The status and rank of the family have been changing over time, and recent phylogenetic analyses indicate that Baissidae may be paraphyletic to Aulacidae + Gasteruptiidae. The genus Manlaya Rasnitsyn, 1980 is the most diverse and widespread in the family, including representatives from western and eastern Laurasia. Here, we describe Manlaya minima sp. nov. from the Lower Cretaceous Shouchang Formation (Zhejiang Province, China). The new species has elbowed second medial cell, similar to Electrobaissa Engel, 2013, although the rest of the characters match with Manlaya, indicating that this character might be related to interspecific variability rather than differences between genera. The co-occurrence of Manlaya in the contemporaneous Shouchang Formation and the Jehol biota may point to a connection between the two entomofaunas. A key to the species of the family Baissidae from China is provided.
拜氏胡蜂（膜翅目：拜氏胡蜂科）是埃瓦尼奥超科中的一个科，由7个属的36个物种组成，分布时间跨度从贝里亚阶（早白垩世）到土伦阶（晚白垩世早期）。该科的地位和等级一直随时间变化，最近的系统发育分析表明，拜氏胡蜂科可能相对于钩腹胡蜂科+腹蜂科是并系的。曼氏胡蜂属（Manlaya Rasnitsyn，1980）是该科中种类最多、分布最广的属，包括来自劳亚大陆西部和东部的代表。在此，我们描述了来自中国浙江省下白垩统寿昌组的新物种——微小曼氏胡蜂（Manlaya minima sp. nov.）。新物种有肘状的第二中室，与2013年的电拜氏胡蜂（Electrobaissa Engel）相似，尽管其余特征与曼氏胡蜂属相符，这表明该特征可能与种内变异有关，而非属间差异。曼氏胡蜂属在同期的寿昌组和热河生物群中的同时出现可能表明这两个昆虫区系之间存在联系。本文还提供了中国拜氏胡蜂科物种检索表。
