Abstract The study of caddisflies in mid-Cretaceous Burmese amber is still in its infancy, it being too early to get more than a preliminary overview of the Trichoptera fauna. With description here of two new and significant taxa: Cretacoptila botosaneanui gen. et sp. nov., Electrocentropus dilucidus gen. et sp. nov. a total of 34 named species are listed, distributed among 10 families. Several taxonomic changes are made: two established species are transferred to more-appropriate genera, becoming Neucentropus macularis ( Wang et al. 2019 ) comb. nov. and Myanpsyche malaisei ( Wichard & Wang, 2019 ) comb. nov.; a new extinct subfamily †Burminoptilinae subfamily nov. is proposed in the family Hydroptilidae and two extinct families, †Burmapsychidae fam. nov. and †Cretapsychidae fam. nov., are proposed for the superfamily Sericostomatoidea. The small size of adults of many of these species is remarkable. With their 2–4 mm length forewings they are smaller than their next relatives in the Baltic Amber and even much smaller than their present representatives. Thus, not only are the hydroptilids “microcaddisflies”, but also philopotamids of the genus Wormaldia and psychomyiids of the extinct genus Palerasnitsynus, which, being the most common caddisflies in Burmese amber, apparently tended to swarm.

白垩纪中期缅甸琥珀中石蛾（昆虫纲、毛翅目）的概述

摘要 中白垩世缅甸琥珀中石蛾的研究仍处于起步阶段，仅对毛翅目动物群进行初步概述还为时过早。这里描述了两个新的重要分类群：Cretacoptila botosaneanui gen。等 sp. 十一月，Electrocentropus dilucidus gen。等 sp. 十一月 共列出了34个命名物种，分布在10个科中。进行了几项分类学更改：两个已建立的物种被转移到更合适的属，成为 Neucentropus macularis (Wang et al. 2019) 梳子。十一月 和 Myanpsyche malaiisei (Wichard & Wang, 2019) 梳理。十一月；一个新的灭绝亚科 †Burminoptilinae 亚科 nov。在 Hydroptilidae 科和两个已灭绝的科 †Burmapsychidae fam 中提出。十一月 和†Cretapsychidae fam。11 月，被提议用于 Sericostomatoidea 总科。许多这些物种的成虫体型小是值得注意的。它们的前翅长 2-4 毫米，比它们在波罗的海琥珀中的下一个亲戚要小，甚至比它们现在的代表要小得多。因此，不仅是水蛾属的“微石蝇”，还有 Wormaldia 属的 philopotamids 和已灭绝的 Palerasnitsynus 属的psychyiids，它们是缅甸琥珀中最常见的石蝇，显然倾向于成群结队。
