Contribution to the Neotropical Campylochetini: A review of Campylocheta Rondani, 1859 (Diptera: Tachinidae) with new synonyms, three new species and an identification key to Neotropical species

open access: yesAustral Entomology, Volume 64, Issue 4, November 2025.
Abstract The large genus Campylocheta Rondani, 1859, comprising 48 species, occurs in all major biogeographical regions of the world, except Antarctica. Homohypochaeta Townsend, 1927 and Hypochaetopsis Townsend, 1915 are two Neotropical genera similar to Campylocheta, with only two and one species respectively.

Great minds map alike: Citizen and expert distribution models of schistosome snail hosts in rural west Uganda

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Citizen scientists and an expert jointly monitor Biomphalaria snails (the intermediate host of Schistosoma mansoni) in rural areas of southwest Uganda, generating over 4500 georeferenced records. By comparing expert‐ and citizen‐based distribution models under perfect and imperfect detection, we demonstrate that site type and NDVI consistently ...

Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

A Short‐Read Amplicon Sequencing Protocol and Bioinformatic Pipeline for Ecological Surveillance of Dipteran Disease Vectors

open access: yesMolecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Vector control remains an important strategy worldwide to prevent human infection with pathogens transmitted by arthropods. Vector control strategies rely on accurate identification of vector taxa along with vector‐specific biological indicators such as feeding ecology, infection prevalence and insecticide resistance.

Phylogenomic approach to integrative taxonomy resolves a century‐old taxonomic puzzle and the evolutionary history of the Acromyrmex octospinosus species complex

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 469-494, July 2025.
A comprehensive, integrative study approach combining morphology, population genetics, phylogenetics and biogeography revealed that the Acromyrmex octospinosus species complex consists of two species: A. octospinosus and its social parasite A. insinuator.
