Olfactory learning in two Amblypygi species Paraphrynus laevifrons and Phrynus pseudoparvulus

  Olfactory learning in two Amblypygi species Paraphrynus laevifrons and Phrynus pseudoparvulus Abstract A wide diversity of arthropod taxa have demonstrated the capacity for learning, but most of our current understanding comes from only a select subset of this highly diverse clade, with most studies focusing on various insect groups. Amblypygids (Order Amblypygi, Class Arachnida), however, are emerging as a model group for studying sensory integration and the neural substrates associated with learning and memory, especially as it relates to navigation. These nocturnal creatures possess specialized sensory appendages and one of the largest and most complex mushroom bodies - the part of the arthropod brain associated with learning and memory - of any arthropod. Prior field studies on multiple species demonstrate sophisticated homing abilities while laboratory-based behavioral assays in  Phrynus marginemaculatus  confirm olfactory-based learning associated with a refuge.

New records of spiders (Arachnida: Araneae) from Azerbaijan, including the first record of Nephilidae from the Western Palaearctic

Abstract
New faunistic data on spiders of Azerbaijan are presented. Thirteen species are recorded from this country for the first time: Araniella villanii Zamani, Marusik & Šestáková, 2020 (Araneidae), Cesonia aspida Chatzaki, 2002, Civizelotes solstitialis (Levy, 1998), Cryptodrassus hungaricus (Balogh, 1935), Gnaphosa cumensis Ponomarev, 1981, G. ukrainica Ovtsharenko, Platnick & Song, 1992, Micaria atropatene Zamani & Marusik, 2021, Trichothyse senilis (O. Pickard-Cambridge, 1872), Turkozelotes attavirus Chatzaki, 2019 (all Gnaphosidae),Trichonephila clavata (L. Koch, 1878) (Nephilidae), Neottiura uncinata (Lucas, 1846), Paidiscura pallens (Blackwall, 1834)(both Theridiidae), and Xysticus edax (O. Pickard-Cambridge,1872) (Thomisidae); the genera Cesonia Simon, 1893 and Trichonephila Dahl, 1911 are newly recorded from the Caucasus. The record of T. clavata represents the first documented introduction of this family in the Western Palaearctic.
