  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 ...

Three new species of orb-weaver spiders (Araneidae) from Humid Chaco in south-west Paraguay

Abstract 


Three new species of orb-weaver spider are described from Paraguay. Kaira mbywangiae sp. nov. has a remarkable complexity of abdominal humps and hump regions. Two species are described from the Humid Chaco flooded wetland region of Ñeembucú (Eustala davalosae sp. nov. and Kaira mbywangiae sp. nov.), and one from an Atlantic rainforest fragment in eastern Itapuá (Mangora sandovalae sp. nov.).
