Abstract

Two new species of the Chilean endemic genus Neogonyleptes Roewer, 1913 are described based on specimens obtained in the Nahuelbuta mountain range, Biobo and La Araucana Regions. The new taxa are morphologically allied to Neogonyleptes karschii (Srensen, 1902); however, both differ from all species of the genus by their dorsal scutum area III+IV, which is armed with a large, apically bifurcate apophysis. Neogonyleptes floresi sp. nov. differs from N. pedrazai sp. nov. principally in the slender body and legs, the proximal constriction of the scutal apophysis, and the distally straight prolateral apophysis on coxa IV. Detailed descriptions, illustrations, and comparisons of the new species are given. Additionally, some comments are provided about the taxonomy of Neogonyleptes and allied genera.

摘要

描述了基于在纳韦尔布塔山脉、比奥比奥和拉阿劳卡纳地区获得的标本的智利特有属 Neogonyleptes Roewer，1913 的两个新种。新分类单元在形态上与 Neogonyleptes karschii (Srensen，1902) 密切相关；然而，它们与该属的所有物种都不同，因为它们的背盾区 III+IV 带有一个大的、顶部分叉的突起。Neogonyleptes floresi sp. nov. 与 Neogonyleptes pedrazai sp. nov. 的主要区别在于身体和腿部细长、盾突近端收缩以及第四 Coxa 上直的近端突起。给出了新种的详细描述、插图和比较。此外，还对 Neogonyleptes 和相关属的分类学进行了一些评论。
