Dorsolateral head muscles of the catfish families Nematogenyidae and Trichomycteridae (Siluriformes: Loricarioidei): comparative anatomy and phylogenetic analysis

open access: yesNeotropical Ichthyology
The skeletal muscles of the dorsolateral region of the head of the Nematogenyidae and representatives of the all major clades of the Trichomycteridae are described and illustrated.

open access: yes, 2018
Calyptrates are a megadiverse, actively radiating, group of dipterans, which are widely spread and abundant in nearly all terrestrial environments. Despite huge diversity and economic importance, their phylogeny is far from resolved.

Genomic analysis of Plebejus Kluk (Lycaenidae: Polyommatinae) clarifies taxonomy within Europe

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The first genomic analysis for the genus Plebejus in Europe is presented, based on ddRAD sequencing data comprising all European Plebejus plus some Asian and North American taxa. Plebejus idas is recovered as paraphyletic, Plebejus corsicus as a subspecies of Plebejus argus and Plebejus villai as a population of Plebejus bellieri, totalling 4 species ...

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Alone no more—Integrative taxonomy of New Zealand odd‐clawed spiders challenges the monotypy of Pianoa and Gradungula (Araneae: Gradungulidae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Taxonomic revision of New Zealand Gradungulidae reveals unexpected northern South Island diversity through integrated molecular phylogenetics and targeted field sampling. Two new species formally described — Gradungula kahurangi sp. nov. and Pianoa civis sp. nov. — with revised male genitalia diagnoses for all three New Zealand genera.

Phylogeny, systematics and evolution of mimicry patterns in Neotropical limenitidine butterflies

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The most comprehensive phylogeny for Adelpha reveals that it is not monophyletic, supporting the description of the new genus Adelphina for the alala‐group. The rate of mimicry evolution increases towards the tropics, consistent with the hypothesis of stronger biotic interactions near the equator.
