  First record of Thaumasia Perty, 1833 nursery web spider (Araneae: Pisauridae) preying upon Polistes canadensis (Linnaeus, 1758) (Hymenoptera: Vespidae) in the Neotropical region Abstract Thaumasia Perty, 1833 are opportunistic spiders that inhabit the Neotropical region. This study reports a spider of the genus Thaumasia preying upon Polistes canadensis (Linnaeus, 1758) in semiarid region of Brazil. A spider of the genus Thaumasia was observed moving rapidly from the fountain's water surface to capture an individual of P. canadensis . After successfully capturing the wasp, Thaumasia sp. was observed partially perched on the wall of the fountain, with the prey still on the water surface and trapped by its chelicerae. The pedipalps and chelicerae of Thaumasia sp. manipulated the head of P. canadensis , which stopped moving shortly after being captured, probably because of the action of the spider's venom. The study records a wasp in the diet of Thaumasia based on the ca...

The story of a Tailless Whip Scorpion in Eastern Mediterranean: First report of Sarax ioanniticus (Kritscher, 1959) in Cyprus (Amblypygi: Charinidae)

Abstract

Amblypygi, commonly known as tailless whip scorpions or whip spiders, is an order of Arachnida noted for its cryptic habits and predominantly tropical and subtropical distribution. Although the group was first mentioned on the island of Cyprus in 1990, no specific taxonomic information was provided at the time. Through a combination of literature review, targeted field surveys, and citizen-science contributions, we confirm the presence of Sarax ioanniticus (Kritscher, 1959) in Cyprus, representing the first documented record of this species on the island. Following seven years of dedicated searches, a live specimen was collected in 2023 and identified, thereby establishing S. ioanniticus as part of the island’s fauna. This finding extends the known range of S. ioanniticus within the Eastern Mediterranean and underscores the importance of integrating biodiversity research with public engagement to detect elusive or underreported taxa. Future studies should investigate the species’ local distribution, ecological requirements, and potential conservation concerns on Cyprus.
