A new fossil from the Eocene of Iran provides new insights regarding the evolution of the morphologically bizarre tube‐eye fish

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Stylephoriformes are a morphologically bizarre lineage of deep‐sea fishes, currently represented by a single extant species, Stylephorus chordatus, the so‐called tube‐eye fish. The phylogenetic relationships of the Stylephoriformes were extensively debated until recent genomic studies proposed a sister‐group relationship with the Gadiformes ...

A giant plagiosaurid temnospondyl from Bjørnøya (Svalbard, Norway) and the origin of the plagiosaurid body plan

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract An articulated temnospondyl skeleton from Middle Triassic deposits of Bjørnøya (Bear Island) in the western Barents Sea is described as a new plagiosaurid genus and species, Arctobatrachus urdensis. With a body length well exceeding 2 m, it represents by far the largest known member of the Plagiosauridae.

Functional chloroplasts in metazoan cells - a unique evolutionary strategy in animal life

Frontiers in Zoology, 2009
Background Among metazoans, retention of functional diet-derived chloroplasts (kleptoplasty) is known only from the sea slug taxon Sacoglossa (Gastropoda: Opisthobranchia). Intracellular maintenance of plastids in the slug's digestive epithelium has long

Unearthing Mesozoic beetles through micro‐computed tomography: A new family of Archostemata and the first representatives of Ommatidae and †Notocupes from the Crato Formation

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
First formally described Archostemata beetles from the Lower Cretaceous Crato Formation are reported, representing the earliest records of the suborder from western Gondwana. Micro‐computed tomography enabled three‐dimensional reconstruction of partially exposed fossils, revealing previously hidden dorsal and ventral morphological characters relevant ...

Complete chloroplast genome sequence of a tree fern Alsophila spinulosa: insights into evolutionary changes in fern chloroplast genomes

BMC Evolutionary Biology, 2009
Background Ferns have generally been neglected in studies of chloroplast genomics. Before this study, only one polypod and two basal ferns had their complete chloroplast (cp) genome reported.

Phylogeny‐based generic delimitations of the diverse leafhopper tribe Gyponini, including the establishment of a new tribe of Iassinae (Hemiptera: Cicadellidae)

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
Phylogenetic relationships among 97.6% of Gyponini genera and 97.4% of subgenera were inferred using morphological and multilocus molecular data. Analyses support the monophyly of Gyponini, transfer Hoplojassini to Hylicinae and establish Chilenanini trib. nov. within Iassinae.

Inconsistencies in the Classification of the Family Cydnidae (Hemiptera: Heteroptera: Pentatomoidea) Revealed by Molecular Apomorphies in the Secondary and Tertiary Structures of 18S rRNA Length-Variable Region L (LVR L)

International Journal of Molecular Sciences
The SSU nuclear rDNA (encoding 18S ribosomal RNA) is one of the most frequently sequenced genes in the molecular analysis of insects. Molecular apomorphies in the secondary and tertiary structures of several 18S rRNA length-variable regions (LVRs) located within the V2, V4, and V7 hypervariable regions can be good indicators for recovering monophyletic
