A revised classification of the assassin bugs (Hemiptera: Heteroptera: Reduviidae) based on combined analysis of phylogenomic and morphological data

open access: yesSystematic Entomology, Volume 50, Issue 1, Page 102-138, January 2025.
This study produces the first combined morphological and molecular phylogenetic analysis for Reduviidae and reveals synapomorphies and diagnostic traits for clades at the ranks of subfamilies and tribes. Based on our resulting robust phylogenetic reconstructions and subsequent optimization of morphological character information, we propose a ...

A new exceptionally preserved sawfly fossil (Hymenoptera: Pergidae) and an evaluation of its utility for divergence time estimation and biogeography

open access: yesSystematic Entomology, Volume 50, Issue 1, Page 237-251, January 2025.
We describe the first Australian Pergidae fossil species, Baladi warru, from McGraths Flat, a newly discovered Miocene Konservat‐Lagerstätte in Australia. The specimen contains pollen grains from Quintianapolis that were imaged with high‐resolution using SEM.

Disentangling the mechanisms by which nitrogen addition affects soil communities and their functioning [PDF]

open access: yes
This thesis aims to explore the impact of nitrogen enrichment on soil communities and their functional dynamics. Specifically, we have investigated the direct effect of nitrogen enrichment on soil community and functioning and indirect effects mediated ...

The evolution of head structures in acercaria (insecta) [PDF]

open access: yes, 2015
Die Acercaria sind eine morphologisch und biologisch sehr diverse hemimetabole Insektengruppe mit ca. 113.000 beschrieben Arten. Die Nahrung bzw. die Ernährungsweisen spielten offenbar eine entscheidende Rolle in der Evolution der Acercaria, weshalb die ...

FINE STRUCTURAL STUDIES ON MAJOR LARVAL MOUTH PART SENSILLA OF ANTHERAEA ASSAMENSIS, AN ENDEMIC SILK MOTH SPECIES OF NORTH EAST INDIA IN REGARD TO SENSORY PHYSIOLOGY [PDF]

open access: yes, 2016
The larval mouth part sensilla trichodea in Antheraea assamensis revealed differential distribution pattern of pores and lumen in different parts of the same sensilla. Pores were sparse in the tip as compared to the middle portion.
