Phylogenetics and taxonomy of the Indo-Australian genus Ulonemia sensu Drake (Hemiptera: Tingidae), with the recognition of new genera and species collected from Proteaceae in Australia Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-29 Ryan Shofner, Gerasimos Cassis
Tingid classification has been problematic since the recognition of the family. The exaggerated ornamentation of many tingids has caused confusion in morphology-based phylogenies due to convergence. Also, some genera, like Ulonemia, lack exaggerated structures and their diagnoses rely on reduced morphology, making identification difficult. The relationship between these genera is of great interest

Genomic diversity, evolutionary history, and species limits of the endemic Ethiopian laminate-toothed rats (genus Otomys, Rodentia: Muridae) Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-25 Daniela Mizerovská, Aleksey A Martynov, Ondřej Mikula, Anna Bryjová, Yonas Meheretu, Leonid A Lavrenchenko, Josef Bryja
The Ethiopian Highlands represent one of the most important centres of endemism on Earth. Six endemic species of laminate-toothed rats have been reported from Ethiopia in a previous study based mostly on morphological analyses. Largely missing genetic data for some of the species, insufficient sampling across Ethiopia, and presence of a pseudogene on cytochrome b created knowledge gaps in basic taxonomy

Dental eruption and adult dentition of the enigmatic ptolemaiid Qarunavus meyeri from the Oligocene of the Fayum Depression (Egypt) revealed by micro-computed tomography clarifies its phylogenetic position Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-17 Panagiotis Kampouridis, Josephina Hartung, Felix J Augustin, Haytham El Atfy, Gabriel S Ferreira
The Palaeogene is a very important time period for mammalian evolution because it documents the first occurrence of many groups. One such group is the enigmatic Ptolemaiida, best known from the Early Oligocene of the Fayum Depression in Egypt, where it is represented by three genera, Ptolemaia, Qarunavus, and Cleopatrodon, including five species. Among these, Qarunavus meyeri is especially rare, as

The first report of Champsosaurus lindoei (Choristodera: Champsosauridae) from the Campanian of the United States: anatomical, phylogenetic, and palaeoecological significance Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-17 Thomas W Dudgeon, Jordan C Mallon, David C Evans
Although the neochoristodere Champsosaurus is well documented in Campanian deposits of western North America, species-diagnostic remains from these strata are restricted to the Dinosaur Park Formation of Alberta, Canada. Here, we describe an exceptionally well-preserved specimen of Champsosaurus lindoei from the Two Medicine Formation of Montana, USA—one of the few occurrences of the genus within the

Eocene origin of anemone-carrying behaviour in polydectine crabs (Brachyura: Xanthidae) Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-16 Lennart Gries, Juraj Paule, Moritz Sonnewald, Maria A Nilsson
The crabs in the subfamily Polydectinae (family Xanthidae) have adapted a defence behaviour in which living invertebrates are used as protection from predators. The polydectine crabs carry a living invertebrate, a sea anemone or nudibranch, in each claw, which is positioned in front of the body and waved to scare off attackers. In an attempt to trace the origin of this behaviour, we sequenced the complete

Hiding in the mists: molecular phylogenetic position and description of a new genus and species of snake (Dipsadidae: Xenodontinae) from the remote cloud forest of the Lost World Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-16 Philippe J R Kok, D Bruce Means
Pantepui s.l. is a remote, biodiverse region of ~400 000 km2 containing at least five endemic reptile genera and a number of ancient vertebrate lineages. Here, we describe an additional endemic snake genus and species, Paikwaophis kruki gen. nov., sp. nov. (Dipsadidae: Xenodontinae), recently collected in the Pantepui cloud forest that sits at the base of the steep cliffs of Roraima-tepui and Wei-Assipu-tepui

Evolutionary history, biogeography, and a new species of Sphoeroides (Tetraodontiformes: Tetraodontidae): how the major biogeographic barriers of the Atlantic Ocean shaped the evolution of a pufferfish genus Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-16 Gabriel S Araujo, Yan R Kurtz, Ivan Sazima, Pedro Hollanda Carvalho, Sergio R Floeter, Anderson Vilasboa, Matheus M Rotundo, Carlos E L Ferreira, João Pedro Barreiros, Diane E Pitassy, Alfredo Carvalho-Filho
Tetraodontidae is the most speciose family of Tetraodontiformes and is represented by fish popularly known as pufferfishes. They are characterized by modified jaws with four dental plates and the ability to inflate their bodies. Tetraodontids are distributed throughout the world and have a wide range of habitat use. One of its genera, Sphoeroides, shows a biogeographical pattern, with 19 of its 21

Effects of Quaternary climatic oscillations over the Chacoan fauna: phylogeographic patterns in the southern three-banded armadillo Tolypeutes matacus (Cingulata: Chlamyphoridae) Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-14 Alejandro Manuel Ferreiro, Juan Diego Pinotti, Sebastián Poljak, Esteban Soibelzon, Marina B Chiappero
The southern three-banded armadillo, Tolypeutes matacus, is one of the most representative species of the South American Chaco region. The susceptibility of this species to climatic changes and its good number of paleontological records has led to the study of their range dynamics for untangling the effects of Quaternary oscillations. These studies yielded contradictory results, suggesting expansion

Environmental DNA metabarcoding of Danish soil samples reveals new insight into the hidden diversity of eutardigrades in Denmark Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-14 Frida Løkkegaard Pust, Tobias Guldberg Frøslev, Reinhardt Møbjerg Kristensen, Nadja Møbjerg
Tardigrades are rarely included in large biodiversity surveys, mainly because of the impracticalities that follow larger sampling and identification of these microscopic animals. Consequently, there is a lack of data on their biogeographical distribution. Here, we analyse environmental DNA sequences of eutardigrades obtained with a metabarcoding protocol on Danish soil samples collected during a national

Ecomorphological correlates of inner ear shape in Australian limb-reduced skinks (Scincidae: Sphenomorphini) Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-08-09 Marco Camaiti, James Wiles, Rocio Aguilar, Mark N Hutchinson, Christy A Hipsley, David G Chapple, Alistair R Evans
The inner ear labyrinth is an organ able to perceive balance and spatial orientation, but the drivers of its morphological variation across and within vertebrate lineages are unclear. We assess two competing hypotheses whether this organ, and specifically the semicircular canals, modifies its shape as a functional adaptation to ecology and locomotion, or according to the constraints of skull morphology
