A new species of Mesosticta in mid-Cretaceous Kachin amber (Odonata: Platystictidae) [PDF]

Mesozoic
Mesosticta additicta sp. nov., fourth species of this platystictid genus, is described from the mid-Cretaceous Kachin amber, suggesting its endemic diversification in the West Burma Block (WBB), possibly in relation to the geographic isolation of this area during the formation of mid-Cretaceous Kachin amber.

The family Pupinidae (Gastropoda: Caenogastropoda: Cyclophoroidea) from mid-Cretaceous Kachin amber [PDF]

Cretaceous Research, 2023
Inclusions of terrestrial mollusks in Kachin amber are of increasing interest to palaeontologists in recent years. Here we describe a new genus (Cretadiostoma gen. nov.) including two new species (C. caperatum sp. nov., C. umbilicarinatum sp. nov.) of the gastropod family Pupinidae based on 12 specimens from mid-Cretaceous Kachin amber of northern ...

Descriptions of the first females of Embolemus (Hymenoptera: Chrysidoidea) from Kachin (Myanmar) amber [PDF]

, 2021
Embolemus brachypterus sp. nov. and E. micropterus sp. nov. (Hymenoptera: Chrysidoidea: Embolemidae) are described from Kachin (Myanmar) amber. They are the first females of Embolemus known from Kachin amber. The new species are characterized by the reduced wings. A key to the females of Embolemus from Kachin amber is presented.

A True Bug with a True but Unique Chela in 100 Million-Year-Old Amber [PDF]

Insects
Grasping appendages in representatives of the group Insecta are usually of the sub-chelate (jackknifing) type. Only rarely do chelate appendages occur: Carcinothrips (Thysanoptera), Dryinidae (Hymenoptera), and Carcinocorini (Heteroptera).

A Cretaceous sap beetle with specialized mandibles (Coleoptera : Nitidulidae) [PDF]

Royal Society Open Science
Sap beetles (Nitidulidae) are species-rich, highly diverse, widely distributed and exhibit varied food habits. However, studies on nitidulids in Kachin amber are scarce, particularly those involving nitidulids with specialized mandibles.

The third Asilidae (Diptera: Asiloidea) from mid-Cretaceous Kachin amber [PDF]

Annales de la Société entomologique de France (N.S.)
Asilidae, also known as assassin flies, are rare in Mesozoic deposits, with the highest diversity documented from mid-Cretaceous Kachin amber and the Aptian Crato Formation. To enhance our understanding of the past diversity of this group, we describe and illustrate a new genus and species, named Burmatriclis spinosus n. gen. n. sp.

Aposematic coloration from Mid-Cretaceous Kachin amber. [PDF]

Philos Trans R Soc Lond B Biol Sci, 2022
Aposematic coloration is among the most diverse antipredator strategies, which can signal unpleasantness of organisms to potential predators and reduce the probability of predation. Unlike mimesis, aposematic coloration allows organisms to warn their predators away by conspicuous and recognizable colour patterns. However, aposematism has been a regular
