Data from: Sumakuru, a deeply-diverging new genus of lyssomanine jumping spiders from Ecuador (Araneae: Salticidae)

The lyssomanine jumping spider genus Sumakuru gen. n. is here described for Sumakuru bigal sp. n., from the Bigal River Biological Reserve in Ecuador. Known from a single male, the embolus of the palp takes the form of a smoothly arching curve, and appears fully mobile, being connected to the tegulum by a thin sclerite and a twisted hematodocha. Data from four gene regions (28S, 16SND1, CO1, wingless) indicate that Sumakuru is the sister group to all other sampled lyssomanines, diverging deeply on the stem lineage of the clade of other known lyssomanines. Unlike previous molecular results, the sampled species of Lyssomanes Hentz, 1845 are supported as monophyletic, with Chinoscopus Simon, 1900 as the sister to Lyssomanes.本文记述了lyssomanine亚科跳蛛的新属Sumakuru gen. n.及其模式种Sumakuru bigal sp. n.，该新种采自厄瓜多尔比加尔河生物保护区。目前该属仅知1头雄性标本，其触肢（palp）的插入器（embolus）呈平滑弧形，且完全可活动，通过一纤细骨片（sclerite）与扭曲的血囊（hematodocha）连接至盾板（tegulum）。基于4个基因区域（28S、16SND1、CO1及wingless）的分子数据显示，Sumakuru与其余所有已采样的lyssomanine类群构成姊妹群，在已知lyssomanine类群演化支（clade）的茎系上发生了深度分化。与既往分子研究结果不同的是，已采样的Lyssomanes Hentz, 1845物种被支持为单系群（monophyletic），其姊妹群为Chinoscopus Simon, 1900。
