As a researcher and curator at Cuba’s National Museum of Natural History, Dr. Alayón devoted decades to studying arachnids. His publications on spider taxonomy, evolution, and biogeography gave other researchers a stronger foundation for understanding the region’s biodiversity. He also shared that knowledge through teaching and scientific exchange far beyond Cuba. For those of us who care about taxonomy, his legacy is a reminder of the patient work behind every species description: examining specimens, recording differences, and preserving knowledge that others can build upon. His contributions will continue to guide the study of Caribbean spiders for years to ...

Systematic placement of the enigmatic genus Timesius Simon, 1879 (Opiliones, Laniatores, Nomoclastidae), with description of a new species from the Colombian Andes

Abstract 

The enigmatic monotypic genus Timesius Simon, 1879, hitherto assigned to Stygnidae Simon, 1879, is redescribed and its phylogenetic position inferred upon morphological and molecular evidence, resulting in its reallocation to the family Nomoclastidae Roewer, 1943. The type material of Timesius vesicularis (Gervais, 1844), long presumed lost, was rediscovered, and is hereby redescribed and illustrated. Also, a new species, Timesius paramuno sp. nov., is described based on specimens collected in the Páramo ecosystem in the Central Cordillera, Colombia. Timesius vesicularis can be readily distinguished by having two long spines on area III of the dorsal scutum (two short tubercles in T. paramuno sp. nov.) and small whitish-yellow granules on the ocularium and dorsal scutum (vestigial whitish-yellow granules in T. paramuno).
