Drawing setae the digital way

open access: yesZoosystematics and Evolution, 2009
Using Adobe Illustrator the drawing of setae or spines is the most time-consuming part of a digital drawing. These short step-by-step instructions explain how setae are drawn and stored as brushes. The set up of libraries of seta can be speeded up additionally with macros. (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

Phylogenomics reveals the timescale of diversification in Amblycera

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 540-553, July 2025.
Next‐generation sequencing changes the higher taxonomy of Amblycera (Insecta: Phthiraptera). Families Trimenoponidae and Gyropidae merge into Gyropidae; Trinotonidae is a separate family; several genera are paraphyletic. The ancestral host of Amblycera was likely a bird; Amblycera switched to mammals twice.

An insect †Archaeopteryx: Cretaceous amber fossil elucidates the evolution of complex host detection and ovipositor mechanisms in parasitoid woodwasps (Hymenoptera: Orussoidea)

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 630-645, July 2025.
We describe †Cretovelona orussopteryx n. gen. & sp. from Kachin amber. The fossil is examined with synchrotron scanning and integrated into an existing morphological data set for Orussoidea. This fossil parasitoid wasp displays a unique character combination demonstrating intermediate conditions in evolving the complex features employed in echo ...

Evolutionary history, novel lineages and symbiont coevolution in the ant tribe Camponotini (Hymenoptera: Formicidae)

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 646-676, July 2025.
Phylogenomic data illuminate the evolutionary history of the ant tribe Camponotini and its obligate bacterial endosymbiont, Blochmannia, and suggest a Paleotropical Eocene origin of the association. We discover three novel lineages of camponotine ants, previously misidentified as members of the large cosmopolitan genus Camponotus.
