Diversification and evolution of Hawaiian Megalagrion damselflies (Pinapinao, Odonata: Coenagrionidae) Ka Ho‘omāhuahua a me ke Kumu Ho‘omohala o nā Pinapinao Megalagrion o Hawai‘i (Odonata: Coenagrionidae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The ancestor of today's pinapinao, Hawaiian Megalagrion damselflies, diverged from Ischnurinae around 51 MA and likely evolved for over 20 MA before colonizing the Northwestern Hawaiian Islands. An ancestor of Megalagrion colonized the Northwestern Hawaiian Islands and diversified into ecological niches with four new breeding habitats and two new gill ...

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

Star‐Like Radiation of Leucostigma candidescens Populations (Gastropoda: Clausiliidae) and Repeated Changes in Chirality

open access: yesZoologica Scripta, Volume 55, Issue 1, Page 62-73, January 2026.
ABSTRACT Leucostigma candidescens is a rock‐dwelling door snail species, which is widespread in the central and southern Apennines of Italy. The species has been divided into nine subspecies. Three of them are characterised by a change in the coiling direction, which is usually a rare evolutionary event.

Taxonomic Deception via Obvious Traits: Oversplitting in European Vallonia Risso, 1826 (Mollusca: Gastropoda: Valloniidae)

open access: yesZoologica Scripta, Volume 55, Issue 1, Page 37-51, January 2026.
ABSTRACT The status of the six traditionally recognised European Vallonia taxa is considered based on mtDNA and nDNA sequences from five independently sorting loci in combination with morphometric landmark analyses conducted on genetically confirmed shells. These analyses document that only two species are valid (V. costata and V.

Predicting Atlantic Bonefish (Albula vulpes) Fork Length From Head Morphometry

open access: yesJournal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
This study developed predictive models using generalized linear statistical analyses to estimate Atlantic bonefish (Albula vulpes) fork length (FL) dependent on four head morphometry covariates: snout length, eye diameter, postorbital head length, and head length.
