The first Cheliferidae (Pseudoscorpiones: Cheliferoidea) from mid‐Cretaceous Kachin amber

Journal of Systematics and Evolution
Abstract Pseudoscorpiones are a group of small‐sized to medium‐sized arachnids under the species‐rich Chelicerata. They are found in many terrestrial habitats, normally cryptic, including leaf litter and soil, under tree bark or rocks. The fossil record of pseudoscorpions is mainly composed of species belonging to

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).

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

, 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.

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

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes. [PDF]

Insect Sci
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.
