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

AbstractThe 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., Usage notesAlignments and trees for Sumakuru study (Salticidae)Alignments for 28S, 16SND1, CO1, wingless, and maximum likelihood trees from analysis of salticid spider phylogeny, showing placement of Sumakuru within the lyssomanines.Sumakuru-Maddison2016-ForDryad04.nex

摘要 本研究建立跳蛛科（Salticidae）柔跳蛛类（lyssomanine）新属Sumakuru gen. n.，模式种为发现于厄瓜多尔比加尔河生物保护区的新种Sumakuru bigal sp. n.。目前该类群仅记录1头雄性标本，其触肢的插入器（embolus）呈平滑弧形，且可完全活动，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显示，Sumakuru属为所有其他已采样柔跳蛛类群的姊妹群，在已知柔跳蛛类群分支的主干谱系上发生了深度分化。与既往分子研究结果不同，本次采样的柔跳蛛属（Lyssomanes Hentz, 1845）物种被支持为单系群，其姊妹群为Chinoscopus Simon, 1900。
