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.

The Vouched, the Unvouched, and a Digital Phantom: Four Spiders (Araneae) Published for, but Not Occurring in, Ireland

Abstract

The gnaphosid spider Zelotes subterraneus (C. L. Koch, 1833) is formally deleted from the Irish list. The names of three spider species recently published for Ireland would constitute the first Irish records; however, voucher specimens were not collected. Therefore, these species have not been safely shown to be established in Ireland and the names should not be included in an Irish checklist. One of the species is now mapped for Ireland in several digital datasets from two independent putative observations. The importance of robust filtering criteria to avoid such eventualities is noted.
