The species of the genus Hypodynerus de Saussure (Hymenoptera, Vespidae, Eumeninae) occurring in Brazil

ZooKeys, 2013
An identification table and descriptions are given to recognize the two species of Hypodynerus (Hymenoptera: Vespidae: Eumeninae) recorded from Brazil: H. arechavaletae (Brèthes) and H. duckei (Bertoni) comb. n. The lectotype is designated and the

Phylogenomics and biogeography of the cleptoparasitic bee genus Triepeolus Robertson (Hymenoptera: Apidae), with a revised subgeneric classification of Triepeolus and its sister genus, Epeolus Latreille Filogenómica y biogeografía del género de abejas cleptoparásitas Triepeolus Robertson (Hymenoptera: Apidae), con una clasificación subgenérica revisada para Triepeolus y su género hermano, Epeolus Latreille

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...

Pond frog as a predator of hornet workers: High tolerance to venomous stings

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Some animals use stingers to repel attackers, and some predators have evolved tolerance to such stings, enabling them to consume venomous prey. For example, social wasps, such as hornets, use modified ovipositors as venomous stingers to inject venom, which can cause intense pain in humans.

Unveiling Wasps as Potential Pollinators: Floral Traits and Wasp Sociality Intensify Network Centrality in a Highly Diverse Tropical Ecosystem

Journal of Applied Entomology, Volume 149, Issue 10, Page 1520-1531, December 2025.
ABSTRACT Wasps, members of over 90 hymenopteran families, exhibit diverse behaviours, including pollination, predation and parasitism. While wasps are known pollinators in specialised systems, such as the intricate mutualism of fig trees and the deceptive pollination of certain orchids, they have historically been considered ineffective pollinators ...

Incidental pollination by passing animals: An overlooked mechanism?

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1245-1250, September 2025.
The conservation of pollinators is essential for sustaining the ecosystem services of pollen transfer, which support crop production, biodiversity conservation and ecosystem health. While primary pollinators have been the focus of most conservation efforts, subordinate or incidental pollinators have been largely overlooked.

Leveraging museum specimens, genomics and legacy datasets to unravel the phylogeny and biogeography of cryptin wasps (Hymenoptera, Ichneumonidae, Cryptini)

Zoologica Scripta, Volume 53, Issue 3, Page 338-357, May 2024.
Abstract Modern genomic techniques have enabled the generation of phylogenetic datasets of unprecedented scale. However, there are also troves of molecular data accumulated from past studies using Sanger sequencing, often at fine taxonomic scales.

Trophic level and specialization moderate effects of habitat loss and landscape diversity on cavity‐nesting bees, wasps and their parasitoids

Insect Conservation and Diversity, Volume 17, Issue 1, Page 65-76, January 2024.
Differences in species responses with regard to their trophic level, food and habitat specialization, and to habitat loss from local to landscape scales are poorly understood. Using cavity‐nesting communities of bees, wasps and their parasitoids on calcareous grasslands as a model system, we found that species from higher trophic levels experienced ...

Anchored phylogenomics and revised classification of the Miltogramminae (Diptera: Sarcophagidae)

Systematic Entomology, Volume 49, Issue 1, Page 138-155, January 2024.
Anchored hybrid enrichment facilitates the creation of a highly supported phylogenetic hypothesis for the Miltogramminae containing 60% of the currently recognised genera from all biogeographic regions except the Neotropical. The new phylogeny tree facilitates a complete revision of the subfamily including the synonymisation of several genera ...

TRAP-NESTING BEES AND WASPS (HYMENOPTERA, ACULEATA) IN A SEMIDECIDUAL SEASONAL FOREST FRAGMENT, SOUTHERN BRAZIL

Papéis Avulsos de Zoologia
Trap-nesting bee and wasp inventories are common in Brazil but many phytophysiognomies are still poorly studied. The main objective of this study is to survey trap-nesting bees and wasps in a Semidecidual Seasonal Forest fragment.

First records of two Amazonian species of Zethus (Zethoides) Fox, 1899 (Hymenoptera, Vespidae, Eumeninae) in Atlantic Forest fragments in São Paulo state, Brazil [PDF]

Check List, 2015
Zethus Fabricius, 1804 is the largest genus in the subfamily Eumeninae with over 250 species. Its Neotropical representatives are divided into three subgenera: Z. (Zethus) Fabricius, 1804; Z. (Zethusculus) de Saussure, 1855; and Z. (Zethoides) Fox, 1899.
