摘要: Palaeomicromenneus lebanensis gen. et sp. nov. (Araneae: Deinopidae) is described from Upper Neocomian–basal Lower Aptian (ca. 125–135 Ma) Cretaceous amber the Hammana/Mdeyrij outcrop, Lebanon. This oldest known, and possibly first true fossil, deinopid. The lack of ocular modifications in new fossil genus does not ex− clude it having exhibited same net−casting prey capture behaviour as extant deinopids. Alternatively, this prey−capture may be highly derived whether had evolved by Early cannot determined for sure; early deinopids (as diagnosed pedipalp morphology rather than behaviour) have been orb−web weavers their sister taxon Uloboridae.
