摘要

1757年，在澳大利亚描述了一个新的球织蛛科单型属：Abbagen。十一月，与Abba transversa（彩虹，1912）梳。nov.为模式种。它与科中所有其他属的不同之处在于体细胞特征，特别是雄性第一条腿前侧表面有一块约五根长棘，腹部颜色为乳白色表面背面有一对两个中心斑点。A.transversacomb的标本。nov.已经在昆士兰和新南威尔士州采集，那里的物种大部分是夏季成熟的。我们还提供了所有澳大利亚蛛科的属级总结，目前由46属中的230个已描述物种和8个亚种组成。

Abba, a new monotypic genus of orb-weaving spiders (Araneae, Araneidae) from Australia

A new monotypic genus in the orb-weaving spider family Araneidae Clerck, 1757 is described from Australia: Abbagen. nov., with Abba transversa (Rainbow, 1912) comb. nov. as the type species. It differs from all other genera in the family by somatic characters, specifically a patch of approximately five long spines on the prolateral surface of the first leg in males and an abdominal colouration with a pair of two central spots dorsally on a creamy-white surface. Specimens of A. transversacomb. nov. have been collected in Queensland and New South Wales, where the species is largely summer-mature. We also provide a genus level summary of all Australian Araneidae, currently consisting of 230 described species and eight subspecies in 46 genera.
