Description of the larval stages of Gymnochthebius jensenhaarupi and phylogenetic analysis of the relationships with other species of the subfamily Ochthebiinae (Coleoptera: Hydraenidae)

open access: yesEuropean Journal of Entomology, 2005
The three larval instars of Gymnochthebius jensenhaarupi (Knisch, 1924) are described and illustrated, including a detailed analysis of their chaetotaxy and porotaxy. The specimens used in this study were collected with adults of G.

A Survey of the Brazilian Dicranocentrus Schött (Collembola, Orchesellidae, Heteromurini) with the Description of a New Species and Notes on the Genus

open access: yesInsects, 2020
Dicranocentrus Schött is the most diverse and widespread taxon of Neotropical Orchesellidae. In Brazil, the genus is represented by 11 species found in humid forested areas of Atlantic and Amazon forests domains. Here we describe in detail Dicranocentrus

Target capture efficiently resolves the long‐standing taxonomic dead end of Diachrysia moths

open access: yesSystematic Entomology, Volume 51, Issue 2, April‐June 2026.
We demonstrate the high efficiency of the target capture method in elucidating the taxonomy of the cryptic species of Diachrysia chrysitis and D. stenochrysis. Phylogenomic and population structure analyses reveal clear nuclear divergence and asymmetric allele sharing, consistent with historical gene flow rather than recent hybridization.

Redefinition of the genus Allonychiurus Yoshii, 1995 (Collembola, Onychiuridae) with description of a new species from China

open access: yesZooKeys, 2011
In this paper, we describe a new species of the genus Allonychiurus Yoshii, 1995, characterized by the presence of an apical swelling on the fourth antennal segment as well as a combination of chaetotaxic and pseudocellar characters.

Evidence for Cryptic Diversity in the “Pan-Antarctic” Springtail Friesea antarctica and the Description of Two New Species

open access: yesInsects, 2020
The invertebrate terrestrial fauna of Antarctica is being investigated with increasing interest to discover how life interacts with the extreme polar environment and how millions of years of evolution have shaped their biodiversity.

The Chaetotaxy of Cypridacea (Crustacea, Ostrocoda) Limbs: Proposals for a Descriptive Model [PDF]

open access: yesBijdragen tot de Dierkunde, 1982
The need for better and more systematic descriptions of the chaetotaxy (especially data concerning the shape, structure and pattern of distribution of the setae) is emphasized. The historical developments of studies in chaetotaxy are reviewed.

Phylogenomics and the evolution of larval feeding habits in the blow flies (Diptera: Calliphoridae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Phylogenomic data from anchored hybrid enrichment provide a new phylogeny of Calliphoridae that delimits the family and confirms division into eight monophyletic subfamilies. Fossil‐calibrated divergence times place the origin of Calliphoridae in the mid‐Eocene (ca. 41 Mya) along with other rapidly radiating families of oestroid Diptera. Reconstruction

The genus Eupodes Koch, 1835 (Acari: Prostigmata: Eupodidae) from southern African soil and vegetation. Part 1. Characterisation of the genus, designation of the type species and descriptions of three new species

open access: yesKoedoe: African Protected Area Conservation and Science, 1997
Based on a study of the Eupodoidea of southern Africa, the genus Eupodes is redefined, with the incorporation of additional features, to distinguish it from other genera. E. striola Koch, 1835 is conceived as type species for the genus. Three new species,

The revival of tribes: An analysis of Platystomatidae (Diptera, Tephritoidea) phylogeny based on external morphological traits

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
First comprehensive phylogenetic hypothesis for the fly family Platystomatidae, based on 194 morphological characters, confirming the monophyly of its four traditional subfamilies. Illustrations of the external and internal morphology of nearly all genera of Platystomatidae are presented here; in addition, a new genus, Trapheroplatystoma gen. nov., and
