  New predatory interaction of Trichonephila clavipes (Araneae: Nephilidae) on Fidicinini (Hemiptera: Cicadidae) in a forest fragment of the Neotropical region Abstract Trichonephila clavipes (Araneae: Nephilidae) is an orb web-building spider whose diet is primarily based on flying insects. This note aims to report the first predatory interaction of T. clavipes on a cicada of the genus Fidicina (Hemiptera: Cicadidae) in a fragment of the Atlantic Forest in Brazil. The predation event was observed (ad libitum) in the Benjamin Maranhão Botanical Garden situated in the Mata do Buraquinho Wildlife Refuge, northeastern Brazil. A specimen of Fidicina sp. was found freshly dead and trapped in the web of T. clavipes. The nephilid was observed moving slowly between the ventral and dorsal regions of the Fidicina sp. without weaving a web around the cicadid. Then, T. clavipes was observed perched on the left side of the Fidicina sp., with its pedipalps and chelicerae manipulating the thorax ...

Two new species of Spinosatibiapalpus Gabriel & Sherwood, 2020 (Araneae: Theraphosidae) from Colombia

Abstract
Two new species of the genus Spinosatibiapalpus Gabriel & Sherwood, 2020 are described: S. paula sp. nov. from the Colombian Caribbean coast and S. neisi sp. nov. from central Colombia. Both species are proposed based on the morphology of the palpal bulb, tibial apophysis and spermathecae. Taxo-nomic keys for all known species of the genus and a distribution map for Colombian species are provided.
