Summary: A new species of Brachypsectridae, Vetubrachypsectra huchengi, is described from Burmese amber, showing distinct differences from the previously reported V. burmitica, primarily in the pedicel-scape attachment and other morphological features. Sexual dimorphism is common in Brachypsectridae.

Summary: A new genus and species of unique-headed bug, Cretocephalus stysi gen. et sp. nov., is described based on a well-preserved specimen from mid-Cretaceous amber from northern Myanmar. The new genus exhibits remarkable differences in diagnostic characters and shares important characters with other subfamilies. Morphological features, including photographs and drawings, are provided, and their importance for the higher classification system of this family is discussed.

Summary: The study describes a new species, Burmusculus angustus sp. nov., in Burmusculidae, and reports a new material of Myanmarina jeannineae in Myanmarinidae, both specimens from mid-Cretaceous amber of northern Myanmar. The research provides a key to all species of Burmusculus and a detailed comparison among species of Myanmarina and Burmusculus, noting a sexual size dimorphism in females with larger body and forewing sizes.

Summary: Marsh beetles play a crucial role in understanding the evolutionary success and ecological morphology of Polyphaga beetles, but their phylogeny has been challenging due to limited fossil records. A new scirtid beetle genus and species, Varcalium lawrencei gen. et sp. nov., has been discovered in Albian-Cenomanian Kachin amber, suggesting the diversification of Scirtinae crown-group in the mid-Cretaceous.

Summary: One new genus of Braconidae (subfamily incertae sedis), Vertibracon gen. nov., with its type species Vertibracon brevistigma sp. nov., and one new species of the genus Tibialobracon van Achterberg & Chen, 2021 (Braconidae, Protobraconinae), Tibialobracon laevis sp. nov. are described from mid-Cretaceous amber of northern Myanmar. An updated key to genera of Braconidae found in Cretaceous ambers, including Vertibracon gen. nov., is provided in this study.

Summary: Mimarachnidae is an extinct planthopper family of the superfamily Fulgoroidea, known exclusively from the Cretaceous. A new fossil species of Ayaimatum and a new genus and species of Mimarachnidae were described from mid-Cretaceous amber of northern Myanmar. These findings further confirm the high morphological disparity of this extinct hemipteran group during the late Mesozoic.

Summary: In this study, multiple new families, subfamilies, tribes, genera, and species were described and classified. The diverse composition of insect fauna found in Burmese amber, including species associated with different ecological environments and vegetation types, was discussed in detail. The study also reclassified certain insects and proposed new taxonomic classifications.

Summary: Lophocateridae are a small family within Cleroidea with sparse fossil records in Mesozoic deposits. A new genus and species, Gracilenticrus burmiticus, has been described from mid-Cretaceous amber in Myanmar, expanding the diversity of lophocaterids. Morphological analysis places Gracilenticrus burmiticus within Lophocateridae, shedding new light on the early evolution of the superfamily Cleroidea.

Summary: In this study, a new genus and species of sap beetles were discovered in mid-Cretaceous amber in northern Myanmar, enriching the fossil record of the family in this region. The new genus is distinct due to its broad prosternal process, suggesting its classification in the Nitidulidae family.

Summary: This paper provides a brief review of scorpionflies recorded in the late Albian Kachin amber. In total, 8 genera and 12 species belonging to 6 families have been found in the amber, indicating higher diversity than expected for mid-Cretaceous scorpionflies. The paleodiversity, phylogeny, and paleoecology of each family are summarized, providing significant fossil data for unraveling the evolutionary history of scorpionflies.

Summary: Two new genera and seven new species are described from mid-Cretaceous Burmese amber, showing a high diversity of Serphitidae family in the region. The presence of multiple endemic groups in the Western Burma Block as it approached contact with mainland Asia is supported by the discovery of unknown serphitid genera in Burmese amber. The collections from this region may represent a broader range of time and habitats than initially thought, suggesting that we are still in the early stages of documenting the fauna.

Summary: The present study reports the discovery of unique leaflets of a semi-aquatic fern in mid-Cretaceous amber from Myanmar and describes a new species of Marsileaceae. The new species has fan-shaped leaflets without a midvein, dichotomous venation partially anastomosing, and dense hairs on the dorsal base radiating upward. This finding represents the first record of semi-aquatic ferns of the Marsileaceae in Myanmar amber and demonstrates their ecological adaptability in the aquatic environments of the mid-Cretaceous.
