本文报道了一个新属--Escaphiella,它是一组分布于美国南部至智利和阿根廷的36种卵形虫的新属。先前已知的物种被归入Scaphiella Simon,而Escaphiella被假设为该属的姐妹群。这两个群体的成员共享一个横向延伸的腹侧盾板和一个独特的女性生殖器构造,但不同的cheliceral形状和刚毛,女性的触须跗骨形状,男性和女性的触须跗骨刚毛,栓子形式,和后呼吸结构。至少有七种Escaphiella的特征是极不寻常的发生之间的不对称的右和左男性pedipalps。在至少8个物种中,左右后正中突起融合成一个单一的正中突起,甚至完全消失。从Scaphiella转移了9个种名:S. hespera Chamberlin(作为模式种)、S. litoris Chamberlin,S. juvenilis(Gertsch和Davis)、S. iguala Gertsch和Davis,S. schmidti Reimoser,S. gertschi Chickering,S. itys Simon,S. scutata Chickering和S.阿根廷比拉本。其中两个名字是新的同义词:E。juvenilis与E. hespera和E. scutata与E. itys。雌性E. hespera为首次描述,并记述了29个新种:E. nye,E. acaclyco、E. colima、E.卡特马科、E.托尼拉、E. chiapa,E.纳亚里特,E. magna和E. olivacea,墨西哥E. viquezi,洪都拉斯和尼加拉瓜的E. tayrona,艾美球虫E. betin和E.来自哥伦比亚的茶E. bolivar,E. Escherades,E. hesperoides、E. maculosa、E. cachimbo,E. aratau,E.巴伊亚、E.波科内,E. blumenau和E. morro,巴西E. exlineae,秘鲁的E. peckorum,E. ramirezi、乌拉圭E. ocoa和E. cristobal和E.来自加拉帕戈斯群岛的伊萨贝拉。
Abstract A new genus, Escaphiella, is established for a group of 36 oonopid species found from the United States south to Chile and Argentina. The previously known species had been placed in Scaphiella Simon, and Escaphiella is hypothesized to be the sister group of that genus. Members of the two groups share a laterally extended ventral abdominal scutum and a distinctive female genitalic conformation, but differ in cheliceral shape and setation, female palpal tarsal shape, male and female palpal tarsal setation, embolus form, and posterior respiratory structure. At least seven species of Escaphiella are characterized by the highly unusual occurrence of asymmetry between the right and left male pedipalps. In at least eight species, the right and left posterior median spinnerets are fused into a single median projection, or even lost entirely. Nine specific names are transferred from Scaphiella: S. hespera Chamberlin (chosen as the type species), S. litoris Chamberlin, S. juvenilis (Gertsch and Davis), S. iguala Gertsch and Davis, S. schmidti Reimoser, S. gertschi Chickering, S. itys Simon, S. scutata Chickering, and S. argentina Birabén. Two of those names are newly synonymized: E. juvenilis with E. hespera, and E. scutata with E. itys. The female of E. hespera is described for the first time, and 29 new species are described: E. nye from California and Nevada, E. acapulco, E. colima, E. catemaco, E. tonila, E. chiapa, E. nayarit, E. magna, and E. olivacea from Mexico, E. viquezi from Honduras and Nicaragua, E. tayrona, E. betin, and E. gigantea from Colombia, E. bolivar from Venezuela, E. cidades, E. hesperoides, E. maculosa, E. cachimbo, E. aratau, E. bahia, E. pocone, E. blumenau, and E. morro from Brazil, E. exlineae from Peru, E. peckorum from Argentina, E. ramirezi from Argentina and Uruguay, E. ocoa from Chile, and E. cristobal and E. isabela from the Galapagos Islands.
