Three new species of the spider genus Speocera Berland, 1914, collected in ferruginous caves in the Carajs region of Par state, Brazil are described: Speocera pinima sp. nov., S. babau sp. nov. and S. piquira sp. nov., all based on males and females. These are abundant species, which have morphological characteristics probably associated with isolation in the subterranean environment. Variation in the shape of the lateral eyes, which can be reduced, and in the eyes colloration bright or opalescent, were observed in all species in this study. These morphological variations may indicate that some populations are in the process of isolation and/or are distributed in different horizons of the subterranean environment, including the Milieu Souterrain Superficiel (MSS). An update of male and female genital structures and specializations to the subterranean environment are discussed.
描述了在巴西帕拉州卡拉雅斯地区的赤铁矿洞穴中采集到的三种新的蜘蛛属 Speocera Berland, 1914 物种:Speocera pinima sp. nov.、S. babau sp. nov. 和 S. piquira sp. nov.,均基于雌雄个体。这些都是丰富的物种,具有可能与地下环境隔离相关的形态特征。在本研究中,所有物种的侧眼形状、眼睛颜色(明亮或乳光)都存在变异,这些变异可能表明一些种群正在隔离和/或分布在地下环境的不同层次,包括浅层地下环境(MSS)。讨论了雄性和雌性生殖器结构以及对地下环境的特殊适应。
