  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 the survey of theridiosomatid spiders (Araneae: Theridiosomatidae) from Qizimeishan National Nature Reserve, China

Abstract

Three species of the spider family Theridiosomatidae Simon, 1881 were identified from Qizimeishan National Nature Reserve, Hubei Province, China, and are presented here. They are Ogulnius barbandrewsi Miller, Griswold & Yin, 2009 (new provincial record), and two new species herein described based on males and females: Theridiosoma subdiwang sp. nov. and T. xiaoshuiense sp. nov. Photos of all three species, along with diagnoses and descriptions of the two new species are provided.
