Abstract

ABSTRACT Two monotypic and troglobitic genera of harvestmen are described from caves in Oaxaca, Mexico: The Karosinae Cruz-López & Francke, 2017 Brujita chapulapa n. gen., n. sp. and the Stygnopsinae Sørensen, 1932 Toojah cimutaa n. gen., n. sp., both based on males only. Also, based on the examination of the male holotype of Hoplobunus planus Goodnight & Goodnight, 1973, the new combination is proposed: Mictlana plana (Goodnight & Goodnight, 1973) n. comb., proposing an emended diagnosis for Mictlana Cruz-López & Francke, 2015, including an analysis of the dilemma of the position of the ocularium and observations on selected homoplastic characters. Finally, on the regard of troglobitic stygnopsids, a review of the exclusive morphological traits exhibit by some representatives of the family is addressed, discussing on the putative synapomorphies of each subfamily.

墨西哥瓦哈卡州Stygonopsidae（Opiliones，Laniatores，Gonyleptoidea）的两个新属和两个新种，并对所选形态特征进行了注释

在墨西哥瓦哈卡州的洞穴中发现了两个单型和双型的收割机属:Karosinae Cruz-López & Francke, 2017 Brujita chapulapa n. gen.， n. sp.和Stygnopsinae Sørensen, 1932 Toojah cimutaa n. gen.， n. sp.，均仅基于雄性。同时，在对平面hopplobunus Goodnight & Goodnight, 1973的雄性全型检验的基础上，提出了新的组合:平面Mictlana plana (Goodnight & Goodnight, 1973) n. comb。，提出了对Mictlana的修正诊断Cruz-López & Francke, 2015，包括对目镜位置困境的分析和对所选同质性状的观察。最后，关于穴居茎突类，对该家族的一些代表所表现出的独特形态特征进行了回顾，讨论了每个亚家族的推定突触。
