  A new species of the genus Spinoctenus Hazzi, Polotow, Brescovit, González-Obando et Simó, 2018 (Araneae: Ctenidae) from Panama A new species Spinoctenus leleji sp. n . is described from Panama based on a male specimen. This is the first record of the genus Spinoctenus from Panama and the second record of this genus outside South America. The new species is most similar to S. tequendama Hazzi, Polotow, Brecovit, González-Obando et Simó, 2018, but differs by the structure of the male palp and the shape of metatarsus IV. Photographs of the habitus and copulatory organs are provided. The type locality of the new species is mapped. Omelko, Мichail M. 2026.

Mystery on the Bounty: The family-level status of Pacificana cockayni Hogg, 1904 (Araneae)

Abstract

The family-level placement of the species Pacificana cockayni Hogg, 1904 (Araneae, Miturgidae) has been ambiguous for over a century, with the monotypic genus initially placed in Agelenidae, later transferred to Amaurobioidinae (Anyphaenidae), and presently in Miturgidae. A recent work describing the male and molecular data consisting of a single mitochondrial gene, cytochrome c oxidase subunit I, confirmed that the species is part of the marronoid clade; however, these data did not result in conclusive family-level placement. Here, we use low-coverage whole genome sequencing (lcWGS) combined with data from the Sequence Read Archive to infer a phylogeny from ultraconserved elements (UCEs) and six legacy Sanger loci. Indications of potential family placements from prior work and the topologies from this study support a transfer of Pacificana Hogg, 1904 to Cycloctenidae Simon, 1898 (new family placement).
