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.

本文记述利氏跳蛛类（lyssomanine）跳蛛的1新属——苏马库鲁跳蛛属（Sumakuru gen. n.），该属以采自厄瓜多尔比加尔河生物保护区的新种大加尔苏马库鲁跳蛛（Sumakuru bigal sp. n.）为模式种。目前仅发现该新种的雄性标本，其触肢（palp）的插入器（embolus）呈平滑弧形，且完全可动，通过一薄骨片（sclerite）与扭曲的血囊（hematodocha）连接至盾板（tegulum）。基于28S、16SND1、CO1及无翅基因（wingless）共4个基因区域的分子数据表明，苏马库鲁跳蛛属与其余所有已采样的利氏跳蛛类群互为姊妹群，在其他已知利氏跳蛛类群的支系（clade）主干谱系上发生了深度分化。与此前的分子研究结果不同，本次采样的Lyssomanes Hentz, 1845属物种被支持为单系群（monophyletic），其姊妹群为Chinoscopus Simon, 1900属。
