Three new species of the long-tailed wasp genus †Megacoxa Brazidec et al., 2024 (Hymenoptera: Megalyridae) from Kachin amber

European Journal of Taxonomy
†Megacoxa is a recently described extinct genus of Megalyridae Schletterer, 1889 from Kachin amber with three described species until now. Here, we investigate four new fossils and integrate them in a phylogenetic framework.

Extroparvum occidentale gen. et sp. nov. and the Cretaceous diversification of Lauraceae

American Journal of Botany, Volume 113, Issue 7, July 2026.
Abstract Premise The fossil record of Lauraceae extends back to the Early Cretaceous and comprises numerous flowers. However, phylogenetic relationships of many of these fossil flowers remain unresolved. To better understand the early evolutionary history of Lauraceae, we conducted phylogenetic analyses of living and extinct members of the family and ...

Pagodocerus, a new beetle genus of Mastigocoleidae from mid-Cretaceous Kachin amber (Coleoptera: Dryopoidea) [PDF]

Papéis Avulsos de Zoologia
Mastigocoleidae are an extinct beetle family known from only a few Cretaceous deposits. Here, we describe Pagodocerus volkovitshi gen. et sp. nov., a new mastigocoleid species preserved in mid-Cretaceous Kachin amber.

Roadblocks, Relationality and Resilient Resistance in Post‐coup Myanmar

Development and Change, Volume 57, Issue 3, Page 624-646, May 2026.
ABSTRACT Following Myanmar's military coup in February 2021, the State Administrative Council (SAC) established checkpoints between towns under its control and rural areas increasingly governed by anti‐junta resistance forces. Here, military personnel command trade and extort from people, inflating the price of consumer goods and agricultural inputs ...

A deep dive into the fossil record of diving beetles (Coleoptera: Dytiscidae): Bayesian inferences elucidate their origin and pulsed diversification at the genus level

Palaeontology, Volume 69, Issue 3, 2026.
Abstract Predaceous diving beetles (Dytiscidae) are among the best‐known and most extensively studied beetle clades. Their fossil record, however, remains surprisingly sparse and uneven, failing to reflect their broad extant diversity. Consequently, the study of their evolutionary history, leveraging the fossil record, particularly their ...

New predatory beetle larvae from about 100 million years ago and possible niche differentiation effects in the Kachin amber forest

Swiss Journal of Palaeontology
Beetle larvae are common occurrences in modern terrestrial and freshwater fauna. We can assume that this was the case in the past as well, yet fossil beetle larvae are still reported relatively rarely.

On two rare wasps (Hymenoptera: Ohlhoffiidae; Panguidae) from mid-Cretaceous Kachin amber

Mesozoic
The Kachin amber biota is one of the most extensively studied and well-documented ecosystems of the Cretaceous, with over 2,000 arthropod species described to date.

Divergent defense strategies and niche partitioning in Cretaceous micro‐beetles

Journal of Systematics and Evolution, Volume 64, Issue 2, Page 354-362, March 2026.
We report a new clambid beetle from mid‐Cretaceous Kachin amber, Scutacalyptus kolibaci gen. et sp. nov., characterized by a flattened body and explanate margins. Alongside spiny and conglobating clambid forms, this diversity reflects niche partitioning and varied antipredator strategies in the Cretaceous forest floor.
