Abstract

Wedoquella apnnea sp. nov. and W. karadya sp. nov., two new species of the jumping spider subtribe Freyina are described and illustrated from specimens recently collected in Misiones and Chaco provinces, Northeastern Argentina. The new species are placed into a new group of Wedoquella because, although in body morphology they resemble the Phiale gratiosa group, the genital structures of both sexes more closely resemble those of Wedoquella, and a preliminary analysis based on mitochondrial COI sequences places this new group as sister to Wedoquella rather than to Phiale. Both new species are similar, but can be distinguished mainly by differences in the retrolateral tibial apophysis of the male palp. Females have a slight intraspecific color variation.

跳蛛一新种组及二新种(蜘蛛目,跳蛛科,跳蛛科)
根据最近在阿根廷东北部米西奥内斯省和查科省采集的标本,描述并说明了Freyina跳蛛亚系的两个新种Wedoquella apnnea sp.nov.和W.karadya sp.nov。这些新物种被归入一个新的Wedoquella类群,因为尽管在身体形态上它们类似于Phiale gratisosa类群,但两性的生殖器结构更接近于Wedoqueella的生殖器结构,基于线粒体COI序列的初步分析将这个新类群视为Wedoquellas的姐妹,而不是Phiale的姐妹。这两个新物种是相似的,但主要可以通过雄性须的胫骨后外侧突起的差异来区分。雌性有轻微的种内颜色变化。
