Beyond the glow: proving the unity of pheromones and bioluminescent signals in glow-worm firefly courtship Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2024-04-11 Martin Novák, Pavel Jakubec
Sexual communication in nocturnal fireflies has been presumed to be facilitated exclusively by bioluminescence, which has replaced the pheromones used by diurnal species. Although some fireflies are suspected of using combined signalling, this view has so far not been supported by empirical evidence, and these species have been viewed more as outliers. In this study, we have investigated the visual

Flying singers: spatio-temporal distribution and acoustic dynamics of two species of Carinetini (Hemiptera: Cicadidae) cicadas in sympatry Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-12-09 Riuler C Acosta, Tatiana P Ruschel, Lucas A Kaminski
The natural history of Neotropical cicadas is poorly understood. Here, we describe comparatively the spatio-temporal distribution and acoustic dynamics of two Carinetini cicadas in sympatry: colourful-cicada, Carineta diardi, and eryngo-cicada, Guaranisaria llanoi. Males of both species emit conspicuous acoustic signals during flight, a rare behaviour in cicadas. Although sympatric and synchronic,

Delimiting phylogeographic diversity in the genomic era: application to an Iberian endemic frog Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-12-02 Christophe Dufresnes, Johanna Ambu, Pedro Galán, Fernando Sequeira, Leticia Viesca, Magdalena Choda, David Álvarez, Bérénice Alard, Tomasz Suchan, Sven Künzel, Iñigo Martínez-Solano, Miguel Vences, Alfredo Nicieza
The rich genetic and phenotypic diversity of species complexes is best recognized through formal taxonomic naming, but one must first assess the evolutionary history of phylogeographic lineages to identify and delimit candidate taxa. Using genomic markers, mitochondrial DNA barcoding, and morphometric analyses, we examined lineage diversity and distribution in the Iberian endemic frog Rana parvipalmata

Myrmecophagy in lizards: evolutionary and ecological implications Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-12-02 Lucas B Q Cavalcanti, Gabriel C Costa, Guarino R Colli, Eric R Pianka, Laurie J Vitt, Daniel O Mesquita
Myrmecophagy is one of the most common dietary specializations among vertebrates. Ants are an important food resource for many lizard species. Here, we use a large dataset on ant consumption by lizards (345 species, 33 families) to explore evolutionary and ecological correlates of myrmecophagy across the evolutionary history of lizards. Based on literature and previous empirical work, we develop and

A revision of the higher latitude periwinkle species Laevilitorina caliginosa sensu lato Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-22 Sebastián Rosenfeld, Nicolás I Segovia, Claudia S Maturana, Cristián Aldea, Thomas Saucède, Paul Brickle, Hamish G Spencer, Elie Poulin, Claudio A González-Wevar
The marine gastropod genus Laevilitorina is exclusive to the Southern Hemisphere, with 21 species from southern South America, Antarctica, Australia, New Zealand, and sub-Antarctic Islands. We present a comprehensive revision of Laevilitorina, using molecular and morphological analyses, to address formally the interspecific divergences within the nominal taxon Laevilitorina caliginosa s.l. We confirm

Tardigrade Augean stables—a challenging phylogeny and taxonomy of the family Ramazzottiidae (Eutardigrada: Hypsibioidea) Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-21 Pritam K Dey, Alejandro López-López, Witold Morek, Łukasz Michalczyk
Tardigrade taxonomy is most often hindered by prevalent outdated species descriptions, lack of integrative redescriptions, scarce genetic information, and fragmentary sampling. Here, we diagnose the problems obscuring phylogenetic inference and the taxonomy of the cosmopolitan family Ramazzottiidae. We carried out the most extensive phylogenetic analysis of this family to date, with a considerable

Four new species of dragonfish genus Eustomias (Stomiiformes: Stomiidae: Melanostomiinae) from the western tropical Atlantic, with remarks on Eustomias minimus Clarke, 1999 Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-19 Bárbara T Villarins, Luciano G Fischer, Artem M Prokofiev, Michael M Mincarone
Four new species of the scaleless black dragonfish genus Eustomias are described based on specimens collected during the ABRACOS (Acoustics along the BRAzilian COaSt) expeditions along the Fernando de Noronha Ridge, off northeastern Brazil, western tropical Atlantic. Eustomias (Haploclonus) antea sp. nov. differs from its congeners by having a long chin barbel without appendages, ending in a very small

Fantastic beasts and how to delimit them: an integrative approach using multispecies coalescent methods reveals two new, endemic Dugesia species (Platyhelminthes: Tricladida) from Corsica and Sardinia Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-18 Daniel Dols-Serrate, Giacinta Angela Stocchino, Ronald Sluys, Marta Riutort
Dugesia hepta and D. benazzii are two species found in Sardinia and Corsica. Previous studies have been unable to resolve their evolutionary relationships and there was doubt about the monophyly of D. benazzii. This study used molecular and morphological data to develop a rigorous species-delimitation procedure within an integrative framework. Three different species discovery methods (ABGD, GMYC,

Anthropause on tardigrade urban communities during COVID-19 pandemic restrictions in Salta, Argentina Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-17 Andrea González-Reyes, Alfonsina Grabosky, Mariana Rocha, Florentina Ballardini, Belén Ostertag, Sandra Rodríguez-Artigas, Daniel Fernández, José Corronca
The World Health Organization declared COVID-19 a pandemic on 11 March 2020. The ‘anthropause’ almost emptied our streets of vehicles. In urban areas, automobile traffic is a major environmental factor, and tardigrades can serve as bioindicators of environmental change. During the winter of 2019–2020, samples were taken both before and during the COVID-19 lockdown. In both cases, traffic variables

A new fossil frog (Lissamphibia: Anura) from the Late Cretaceous of Brazil and the early evolution of neobatrachians Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-15 Rodolfo Otávio Santos, Alberto B Carvalho, Hussam Zaher
Although neobatrachians represent about 95% of anuran diversity, their fossil record, especially during the Mesozoic, remains scarce and often limited to a few damaged specimens with uncertain affinities. In South America, fossil neobatrachians have been identified from the Cretaceous deposits in Chile, Argentina, and Brazil. Here, we describe a new species of fossil neobatrachian from the Late Cretaceous

Morphology matters: congruence of morphology and phylogeny in the integrative taxonomy of Clevelandellidae (Ciliophora: Armophorea) with description of six new species Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-14 Michael Kotyk, William A Bourland, Matyáš Soviš, Daniel Méndez-Sánchez, Pavel Škaloud, Zuzana Kotyková Varadínová, Ivan Čepička
Armophorid ciliates of family Clevelandellidae represent ecologically interesting symbionts of ecologically interesting hosts: wood-eating cockroaches of subfamily Panesthiinae unrelated to the termite/Cryptocercus lineage. Moreover, these protists exhibit a peculiar morphology, with the posteriorization of oral structures being the most striking of their unique characters. Despite that, the family

What is a ‘strong’ synapomorphy? Redescriptions of Murray’s type species and descriptions of new taxa challenge the systematics of Hypsibiidae (Eutardigrada: Parachela) Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-14 Piotr Gąsiorek, Brian Blagden, Witold Morek, Łukasz Michalczyk
Hypsibiidae are the most species-rich group within the Hypsibioidea, and three (Diphasconinae, Itaquasconinae, and Pilatobiinae) of its four subfamilies are characterized by a division of the foregut into a rigid buccal and a flexible pharyngeal tube. The aim of this work is to provide a comprehensive background for sound taxonomic studies on several hypsibiid lineages. We redescribe the type species

Searching for Mediterranean bath sponges (Demospongiae: Dictyoceratida: Spongiidae) in the Northeast Atlantic reveals a new species: an integrative taxonomic approach Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-14 Marie Grenier, Charlotte Simmler, Pierre Chevaldonné, Noëlle Callizot, Thierry Pérez
Bath sponges, included in the Spongiidae (Demospongiae: Dictyoceratida), are distributed across the oceans of the world, with a greater abundance in temperate, subtropical, and tropical zones. Their harvest started during ancient times in the Mediterranean Sea, which shed light on the whole family. Most of the Mediterranean Spongiidae have been reported repeatedly from the Northeast Atlantic, notably

A highly polymorphic South American collared lizard (Tropiduridae: Tropidurus) reveals that open–dry refugia from South-western Amazonia staged allopatric speciation Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-11-10 André L G Carvalho, Rafael C B Paredero, David Villalobos-Chaves, Elaine Ferreira, Miguel T Rodrigues, Felipe F Curcio
Research on Pleistocene Amazonian refugia has predominantly targeted forest-dwelling taxa, although evidence suggests that endemic species have also evolved in peripheral Amazonian enclaves of open–dry habitats. In Rondônia, Brazil, Tropidurus lizards are restricted to savannah relicts that were once connected to the core Cerrado biome. These populations are currently allocated under Tropidurus oreadicus
