Graphical Abstract Image

Madagascar is one of the most diverse areas of the world and harbours numerous endemic species. A new genus of ant-eating spiders, Suffascar, was discovered on the island, where it is apparently endemic, common and speciose (with 12 new species). It is well known that ant-eating spiders (Zodariidae) with femoral organs are specialised consumers of ants or termites, although the exact role of these glands, and their importance in a wider phylogenetic context, remains obscure.

IS16065The Australasian spiny trapdoor spiders of the family Idiopidae (Mygalomorphae : Arbanitinae): a relimitation and revision at the generic level

Graphical Abstract Image

The spiny trapdoor spiders of Australia are an iconic and highly diverse component of the Australasian ground-dwelling spider fauna, renowned for their longevity and conservation significance. Following detailed molecular analysis, we present a monographic revision of the family Idiopidae in Australia at the generic level, including an illustrated key to genera, molecular diagnoses for all higher taxa, along with live habitus and burrow images to assist in field identification. This work provides a single reference point for the identification of Australasian Idiopidae and lays the phylogenetic and morphological foundations for future species-level analyses.

Graphical Abstract Image

How much do we know about biodiversity in the ocean? Too little. Even common organisms, such as jellyfish, have many more species to be discovered. Exploration of the Tropical Eastern Pacific and adoption of modern methods revealed 22 new species – a tenfold increase in regional diversity. Genetic and morphological diversity of these species suggests considerable hidden ecological and functional diversity. Photograph by L. Gómez Daglio.

IS17001Taxonomic reassessment of species within the chrysaoros group of Calisto (Lepidoptera : Nymphalidae : Satyrinae)

Rayner Núñez Aguila, Antonio R. Pérez-Asso and Julio A. Genaro
pp. 747-764
Graphical Abstract Image

We reassess the taxonomic status of several Calisto Hübner taxa included in the archebates and hysius species groups. By using COI barcodes and morphological evidence, we recognise Calisto clydoniata Schwartz & Gali and C. chrysaoros Bates as valid species and propose C. clenchi, syn. nov., C. galii galli, syn. nov. and C. galii choneupsilon, syn. nov. as synonyms of C. chrysaoros. Further work must be focused on other species group members to reassess their affinity.

IS16091Astrocoryne cabela, gen. nov. et sp. nov. (Hydrozoa : Sphaerocorynidae), a new sponge-associated hydrozoan

pp. 734-746
Graphical Abstract Image

All the species belonging to the hydrozoan family Sphaerocorynidae live in association with sponges and often show a confusing taxonomic history. According to both morphological and molecular analyses, we herein describe the new genus and species Astrocoryne cabela from the Red Sea and Maldives. The present study suggests that a comprehensive revision of the family is needed to clarify the diversity and evolution of this taxon.

Graphical Abstract Image

We describe a novel genus and species of soft coral from North Carolina. This species was not previously reported in the South Atlantic Bight, suggesting it may not be native to the region. The discovery of this species underscores the value of taxonomic work and highlights the need to investigate and document understudied taxa, including soft corals.

IS17020A spectacular new genus of Staphylinini rove beetle from the tropical Andes and its phylogenetic assessment (Coleoptera : Staphylinidae)

pp. 713-722
Graphical Abstract Image

Neotropical insects are so poorly known that we keep discovering new taxa there, often of a puzzling nature. With the aid of morphology-based phylogenetic analysis, we describe such a rove beetle, a new genus and species placed in the south temperate subtribe Amblyopinina. This is a step towards elucidating Neotropical biodiversity and appreciation of the biogeographic complexity of its core, the tropical Andes.

IS16083Relationships and phylogenetic revision of Filistatinella spiders (Araneae : Filistatidae)

Ivan L. F. Magalhaes and Martín J. Ramírez
pp. 665-712
Graphical Abstract Image

Filistatinella spiders are found in semiarid areas of North America, and represent an ancient branch of the spider tree of life. After investigating specimens deposited in scientific collections, seven new species were discovered, and their morphology suggests Filistatinella are relatives of Pholcoides from Asia. This study suggests that many Filistatidae species remain to be discovered, and adds yet another piece to the puzzle of early spider evolution.
