The order Amphipoda is one of the largest orders in the Crustacea, many species of which are involved in symbiotic relations with other animals. Despite the considerable diversity of the Amphipoda both in number of species and ecology, polychaete-commensalism has been poorly known and described from few species. In particular, there has been little discussion of the evolutionary origins of polychaete-commensalism

A molecular perspective on the systematics and distribution of Loxopholis lizards in South and Central America, with advances on the biogeography of the tribe Ecpleopodini (Gymnophthalmidae: Squamata) Syst. Biodivers. (IF 1.9) Pub Date : 2022-10-10 Sergio Marques-Souza, Katia Cristina M. Pellegrino, Tuliana O. Brunes, Fernando J. M. Rojas-Runjaic, Miguel Trefaut Rodrigues
Knowledge about the biological diversification of vertebrates in the Amazonia has previously relied on taxa that diversified in relatively recent timeframes (i.e. Plio-Pleistocene). Dating of evolutionary events in small lizards and frogs, on the other hand, has progressively demonstrated that the major phylogenetic events in these organisms occurred earlier in time, from the Eocene to the Miocene

Morphological and distributional patterns of native and invasive Trifolium (Papilionoideae, Leguminosae) species in southern South America Syst. Biodivers. (IF 1.9) Pub Date : 2022-10-10 Fernando Carlos De Diego, Federico Omar Robbiati, Juan José Gaitán, Renée Hersilia Fortunato
The ability of a species to colonize new geographical areas is closely related to its morphological response to environmental gradients. Previous studies compared native and alien invasive species in their ability to modify their morphology in reaction to climatic and edaphic factors; however, taxonomically close species have been scarcely analyzed. In this study, morphological variability patterns

Multiples lines of evidence unveil cryptic diversity in the Lophostoma brasiliense (Chiroptera: Phyllostomidae) complex Syst. Biodivers. (IF 1.9) Pub Date : 2022-09-20 Diego A. Esquivel, Maria Joáo Ramos Pereira, John D. Stuhler, Daniela M. Rossoni, Paúl M. Velazco, Filipe Michels Bianchi
Phenotypically similar species – often called cryptic species – represent a challenge for taxonomy and conservation biology because they are usually undetectable to scientists. To unravel these cryptic taxa, studies now employ data from different sources under an integrative approach. We present an assessment of the cryptic diversity of the Lophostoma brasiliense species complex (Chiroptera: Phyllostomidae)

Evolution and biogeography of the Haploniscus belyaevi species complex (Isopoda: Haploniscidae) revealed by means of integrative taxonomy Syst. Biodivers. (IF 1.9) Pub Date : 2022-08-30 Henry Knauber, Jona R. Silberberg, Angelika Brandt, Torben Riehl
The role of geomorphological features as drivers for benthic deep-sea biodiversity remains poorly understood. By disentangling the putative Haploniscus belyaevi Birstein, 1963a species complex from the abysso-hadal Kuril-Kamchatka Trench (KKT) region in the North-west Pacific Ocean, we aim to shed light on deep-sea differentiation and how it is related to potential bathymetric barriers such as the

Species delimitation in the Trichocentrum cepula (Oncidiinae, Orchidaceae) complex: a multidisciplinary approach Syst. Biodivers. (IF 1.9) Pub Date : 2022-08-30 Antonio E. Camelo-Júnior, Alessandro W. C. Ferreira, Ivanilza M. Andrade, Simon J. Mayo, Felipe Nollet, José L. Silva, Maria C. Barros, Elmary Fraga, Edlley M. Pessoa
The Trichocentrum cepula complex comprises three species, T. caatingaense, T. cepula and T. sprucei, endemic to tropical forests east of the Andes in South America. The delimitation of these species has been diversely interpreted due to the extensive morphological variation in the complex. We applied an integrative approach to achieve a better understanding of these biological units, using geometric

Shedding light on taxonomic chaos: Diversity and distribution of South Asian skipper frogs (Anura, Dicroglossidae, Euphlyctis) Syst. Biodivers. (IF 1.9) Pub Date : 2022-08-30 Christophe Dufresnes, Stephen Mahony, Vishal Kumar Prasad, Rachunliu G. Kamei, Rafaqat Masroor, Muazzam Ali Khan, Awadh M. Al-Johany, Kumudani Bala Gautam, Sandeep Kumar Gupta, Leo J. Borkin, Daniel A. Melnikov, Juriy M. Rosanov, Dmitriy V. Skorinov, Amaël Borzée, Daniel Jablonski, Spartak N. Litvinchuk
A known haven of amphibian diversity, South Asia is also a hotspot of taxonomic confusions. Vastly distributed from Saudi Arabia to Myanmar, the dicroglossid genus Euphlyctis (“skittering” or “skipper” frogs) is a representative example. Combining phylogenetic analyses with 16S barcoding and genome size variation of 403 frogs from 136 localities, we examined genetic diversity and distributions across

When did bumblebees reach South America? Unexpectedly old montane species may be explained by Mexican stopover (Hymenoptera: Apidae) Syst. Biodivers. (IF 1.9) Pub Date : 2022-08-18 Paul H. Williams, Elaine Françoso, Baptiste Martinet, Michael C. Orr, Zongxin Ren, José Santos Júnior, Chawatat Thanoosing, Rémy Vandame
A problem for understanding bumblebee biogeography is that if bumblebees dispersed from Asia through North America to South America, if they are poor at long-distance dispersal with establishment o...

Integrative systematic revision of a new genus of Eumolpinae (Coleoptera: Chrysomelidae) endemic to New Caledonia: Dematotrichus gen. nov. and its numerous new hairy species Syst. Biodivers. (IF 1.9) Pub Date : 2022-07-26 JesúS Gómez-Zurita
The monophyletic group of species around Dematochroma pilosa Jolivet, Verma & Mille is identified in this work by combining information from mitochondrial DNA data and morphological features. A series of defining traits diagnosing this species assemblage from its closest phylogenetic relatives, including the genera Thasycles Chapuis and Atrichatus Sharp, is used to argue for its taxonomic separation

Tempestichthys bettyae, a new genus and species of ocean sleeper (Gobiiformes, Thalasseleotrididae) from the central Coral Sea Syst. Biodivers. (IF 1.9) Pub Date : 2022-07-25 Christopher H. R. Goatley, Luke Tornabene
The Thalasseleotrididae is a small family of exclusively marine gobioids. They form a sister taxon to the Gobiidae and Oxudercidae and are distinguished from most species in these families by having six branchiostegal rays and a membrane linking the hyoid arch to the first ceratobranchial. Here we use micro-CT informed morphological data and molecular phylogenetics to describe a new genus and species
