本文记述了产于中安第斯山脉东坡托利马省Villahermosa的一新种：Strengeriana Pretzmann，1971，S.villaensis。该属为哥伦比亚特有种，分布于内华达山脉、圣玛尔塔山脉和安第斯山脉的西部和中部，海拔从700米到2000米不等。随着维拉山山脉的加入，该属的总种数增加到16种。这一新种与其同类的区别主要在于第一个雄性性肢动物的形态，特别是近端、头端和侧面裂片的形状，以及近端和头端的突起。根据第一只雄性性肢动物和第三只上颌足动物的形态特征，提出了该属种的鉴定检索表。
We describe a new species of Strengeriana Pretzmann, 1971, S. villaensis, from Villahermosa, Tolima Department, on the eastern slope of the Central Andes. The genus is endemic to Colombia and is distributed in the Sierra Nevada de Santa Marta and the Western and Central Andes, at elevations ranging from 700 to 2000 m. With the addition of S. villaensis the total number of species in the genus rises to 16. This new species is distinguished from its congeners primarily by the morphology of the first male gonopod, particularly by the shape of the mesial, cephalic and lateral lobes, and the mesial and cephalic processes. We present a key for the identification of the species of the genus based on the morphology of the first male gonopod and the third maxilliped.
