Data from: Phylogenetic placement of the unusual jumping spider Depreissia Lessert, and a new synapomorphy uniting Hisponinae and Salticinae (Araneae, Salticidae)

The relationships of the unusual salticid spider Depreissia from central Africa and Borneo have been difficult to resolve, obscured by its highly modified ant-like body. Phylogenetic analysis of the gene 28S strongly supports its placement outside the major clade Salticinae and within the clade of cocalodines, spartaeines and lapsiines, with weaker support for a relationship with the cocalodines in particular. Excluding the genus from the Salticinae is supported also by the presence of a median apophysis on the male palp, and by the lack of a cymbial apical groove cradling the tip of embolus, which is newly presented here as a synapomorphy of Hisponinae plus Salticinae.

产自中非与婆罗洲的跳蛛科（Salticidae）德普雷蛛属（Depreissia）为一类特殊类群，其分类关系长期难以厘清，高度特化的蚁形躯体掩盖了相关分类学依据。针对28S基因的系统发育分析有力支持，该属类群不属于核心的跳蛛亚科（Salticinae）演化支，而是隶属于包含科卡洛跳蛛类（cocalodines）、斯帕塔跳蛛类（spartaeines）与拉普西跳蛛类（lapsiines）的演化支；不过针对其与科卡洛跳蛛类的专属亲缘关系，仅获得了较弱的支持证据。将该属排除出跳蛛亚科的结论，还得到两项形态学特征的佐证：其一为雄蛛触肢（male palp）上存在中突（median apophysis），其二为缺乏用于托住插入器（embolus）尖端的跗舟顶端凹槽（cymbial apical groove）——本文首次将该特征确立为希斯波纳跳蛛亚科（Hisponinae）与跳蛛亚科的共有衍征（synapomorphy）。
