Abstract
A new Australian genus in the orb-weaving spider family Araneidae Clerck, 1757 is described,Kangaraneusgen. nov., withK. arenaceus(Keyserling, 1886)comb. nov.(New South Wales, Queensland, South Australia, Victoria and Western Australia) as the type species and also including two other species:Kangaraneus amblycyphus(Simon, 1908)comb. nov.(Australian Capital Territory, New South Wales, Queensland, South Australia, Victoria and Western Australia) andK. farhanisp. nov.(Australian Capital Territory, New South Wales, South Australia, Victoria and Tasmania). The new genus is included in the informally termed Australasian ‘backobourkiine’ clade due to the presence of its putative synapomorphies, specifically a single patellar macroseta on the male pedipalp and its median apophysis forming an arch over the radix. It includes medium-sized orb-weaving spiders (total length 3–12 mm) with distinct humeral humps on the almost triangular abdomen. Therefore, within the backobourkiines, it is somatically most similar toNovakiellaCourt & Forster, 1993 but differs considerably in male genitalic characters, including a C-shaped median apophysis with an acute tip. Genitalia are most similar to those inQuokkaraneusCastanheira & Framenau, 2023 from which the new genus differs by the lack of the white colouration and the shape of the abdomen.
