Abstract

The new genus Amazoonops is proposed for a group of species from the Brazilian Amazon that belong to the Varioonops group, which is presently composed by Varioonops Bolzern & Platnick, Ponsoonops Bolzern and Bipoonops Bolzern. In these genera, female lacks the dorsal abdominal scutum, have a reduced abdominal post-epigastric scutum, and the male palp has unfused cymbium and tegulum. The incomplete abdominal epigastric scutum of females and the sternal surface covered with deep pits in both sexes are considered as putative synapomorphies of the new genus. Five new species are described, four from the state of Pará (Amazoonops almeirim sp. nov., A. cachimbo sp. nov., A. caxiuana sp. nov. and A. juruti sp. nov.) and one from the state of Amazonas (A. ducke sp. nov.). Females of A. almeirim sp. nov. and A. ducke sp. nov. are unknown.

摘要

新属Amazoonops是为来自巴西亚马逊地区的一组物种而设立的，这些物种属于Varioonops类群，该类群目前由Varioonops Bolzern & Platnick、Ponsoonops Bolzern和Bipoonops Bolzern组成。在这些属中，雌性缺少腹部背甲，腹部后腹盾片缩小，雄性触肢的跗节和盾片未愈合。雌性不完全的腹部腹盾片以及两性中布满深坑的胸骨表面被认为是新属的假定共衍征。描述了五个新物种，四个来自帕拉州（新种Amazoonops almeirim、新种A. cachimbo、新种A. caxiuana和新种A. juruti），一个来自亚马逊州（新种A. ducke）。新种A. almeirim和新种A. ducke的雌性未知。
