  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 ...

On two wolf spiders from Yintiaoling Nature Reserve of Chongqing, China (Araneae, Lycosidae)

Abstract

Two spiders of the wolf spider family Lycosidae from high altitude area (>1900 m) of Yintiaoling Nature Reserve are presented here, including a new species, Trochosa alpina sp. nov. (male, female) and a poorly known species, Alopecosa pseudocuneata (Schenkel, 1953). The new species is similar to the Holarctic congener, T. ruricola (De Geer, 1778) and Alopecosa pseudocuneata is quite similar to the Palaearctic species, Alopecosa cuneata (Clerck, 1757). Description / redescription, diagnoses, photos and illustrations of these two species are given. Photos of A. cuneata are provided for comparison purposes.
