A review of non-aculeate hymenoptera recorded in the world's Cretaceous amber assemblages is provided herein. Recorded are 287 species (265 named) representing 47 families in 17 amber assemblages. The richest in family number is the Burmese (Kachin) amber (35), followed by Canadian (19), Spanish (15), Kheta (12), Raritan (11), Charentese (10), Agapa (9) and Levantine (7) ones; hymenopterans in other ambers are less well documented. In the eight mentioned amber faunas, the share of extinct families decreases from 50/53 to 21 percent in a good correlation with their putative age, therefore suggesting a contiguous character of the studied world fauna. This inference is confirmed by the fact that endemic families are not recorded, with the only but prominent exception of the insular Burmese (Kachin) fauna with its 8 endemic families (23% of known hymenopteran families there). The rate of gradual loss of extinct families in succeeding amber assemblages shows that the main transformation took place during the first half of the Late Cretaceous, and not the Cretaceous-Paleogene boundary. As taxonomic revisions, two species are placed in different families than originally ascribed to, namely, Albiogonalys elongatus Nel, Perrichot & Néraudeau, 2003, is transferred to Praeaulacidae, and Phoriostephanus exilis Engel & Huang, 2017, is transferred from Stephanidae to Roproniidae.

世界白垩纪琥珀中的非针形膜翅目

本文提供了记录在世界白垩纪琥珀组合中的非针形膜翅目的综述。记录了287种(命名为265种),分别代表17个琥珀色组合中的47个科。家族中最富有的是缅甸(Kachin)琥珀(35),其次是加拿大(19),西班牙(15),Kheta(12),Raritan(11),Charentese(10),Agapa(9)和Levantine( 7)个;其他琥珀中的膜翅目动物记录较少。在提到的八个琥珀动物区系中,灭绝科的比例从50/53下降到21%,与它们的推测年龄有很好的相关性,因此表明所研究的世界动物区系具有连续性。事实并未得到证实,这一推论得到了证实,唯一但突出的例外是岛上的缅甸(Kachin)动物区系有8个地方性科(那里已知的膜翅目科的23%)。灭绝的科系在随后的琥珀组合中逐渐丧失的速率表明,主要的转变发生在白垩纪晚期,而不是白垩纪-古生界。作为分类学的修订,两个物种被放置在与最初归因于不同的科中,即Albiogonalys elongatus Nel(Perrichot和Néraudeau,2003年)移交给了Praeaulacidae;Phoriostephanus exilis Engel&Huang,2017年从Stephanidae转移到了Roproniidae。
