  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 Androctonus from Morocco (Arachnida: Scorpiones: Buthidae)

Abstract


New data are presented on the taxonomy and distribution of the dark species of the genus Androctonus Ehrenberg, 1828 in Morocco and Western Sahara. Three new species, A. argoubi sp. n., A. stockmanni sp. n., and A. vaneki sp. n. from Morocco are described, characterized by having metasoma I–IV ventrally punctate, a character that is well developed in A. stockmanni sp. n., and A. vaneki sp. n., and weakly developed in A. argoubi sp. n. Dark species from Morocco are compared with A. sergenti Vachon, 1948, and A. bourdoni Vachon, 1948. We describe and compare their external morphology, illustrating their characters comprehensively in color photographs. The hemispermatophores of two species are described and illustrated, and a map showing the distributions of the studied species is provided. Furthermore, for all three newly described species, we provided their karyograms, which are very similar (2n = 24) and demonstrate the karyotypic uniformity of the entire genus Androctonus.
