Abstract

A new theridiid spider, , is described from the Kuril Islands (Kunashir). The new genus belongs to the ' clade (clade 24)' of Agnarsson (2004). A pair of raised, fused setal sockets on the cheliceral promargin adjacent to the fang base was found to be another synapomorphy of all the 'distal theridiids' (the 'elongated central claw clade (clade 33)': argyrodins, ' clade' and theridiins). demonstrates a male polymorphism similar to some Simon, 1891 species (e.g., (Hentz, 1850)).

摘要

一种新的球蛛科蜘蛛，，由千岛群岛（国后岛）描述而来。新属属于阿格纳松（2004年）的“ 进化枝（进化枝24）”。在靠近毒牙基部的螯肢前缘发现一对凸起的、融合的刚毛窝，这被认为是所有“远端球蛛科蜘蛛”（“细长中央爪进化枝（进化枝33）”：银鳞蛛属、“ 进化枝”和球蛛属）的另一个共同衍征。表现出与一些1891年西蒙的物种（例如，（亨茨，1850年））相似的雄性多态性。
