Disconnecting trapdoors: Phylogenomic analyses reveal evolutionary contrasts in trapdoor spiders with intercontinental distribution (Idiopidae, Idiopinae).

Among Mygalomorphae spiders, the family Idiopidae is the second most diverse, consisting exclusively of trapdoor spiders and is divided into three subfamilies: Arbanitinae, Genysinae, and Idiopinae. The subfamily Idiopinae, distinguished mainly by anterior lateral eyes that project forward, includes 153 species across seven genera, distributed throughout South America, Africa, and parts of Asia. Within this subfamily, the genus Idiops includes the greatest diversity and is the only genus recorded in both the New and Old Worlds.

Voracity, reaction to stings, and survival of domestic hens when feeding on the yellow scorpion ().

Background: Scorpionism is a worldwide problem that has already made thousands of victims, and multi-disciplinary approaches for controlling their populations are to be more successful. Hens are often mentioned as tools for controlling scorpions; however, systematic/experimental behavioral studies are not available. Moreover, there is no systematic information on the effect of scorpion venoms on hens.

Flying or digging? The trapdoor spider genus Neocteniza Pocock, 1895: Redescription of three species, new records from Brazil, notes on natural history and first record of ballooning for Idiopidae (Araneae, Mygalomorphae).

The Neotropical trapdoor spider genus Neocteniza Pocock, 1895 is distributed throughout Central and South America. The genus currently comprises 18 species and little is known about the biology of these spiders. We provide an amended diagnosis for the genus Neocteniza and the species: N.

Taxonomy of the genus Cyrtopholis Simon, 1892 (Araneae, Mygalomorphae, Theraphosidae): Cuban species described by Pelegrín Franganillo Balboa.

Cyrtopholis Simon 1892 is a spider genus from the Caribbean islands characterized by the presence of stridulatory setae on trochanter of palps and legs I. Franganillo Balboa described eight species of Cyrtopholis Simon 1892 from Cuba between 1926-1936. The type-material is deposited in the Instituto de Ecología y Sistematica do Ministerio de Ciencias, Tecnologia e Meio Ambiente, La Habana, Cuba.

Schismatothelinae spiders (Araneae, Mygalomorphae, Theraphosidae) from Colombia: four new species and an approach to their diversity.

The spider subfamily Schismatothelinae from Colombia is revised. One new species of Euthycaelus Simon 1889 and three new species of Schismatothele Karsch 1879 are named, as well as new geographical records provided. E.
