  New synonymy and combinations in Megamyrmaekion Reuss, 1834 (Araneae: Gnaphosidae) Abstract The drassodine ground spider genus Megamyrmaekion Reuss, 1834 is recorded from Vietnam for the first time as a result of the following new combinations here proposed: M. luridum (O. Pickard-Cambridge, 1874) comb. nov., ex Drassodes Westring, 1851, and M. vickyae (Sherwood, Marusik, Sharp & Ashmole, 2023) comb. nov., ex Australoechemus Schmidt & Piepho, 1994. Detailed redescriptions and illustrations of the male and female of M. luridum comb. nov., from Vietnam are provided. Additionally, A. celer Schmidt & Piepho, 1994 syn. nov., is recognized as a junior synonym of M. caudatum Reuss, 1834. Drassus tarrhunensis Karsch, 1881 is removed from the synonymy of M. caudatum and provisionally transferred to the genus Megamyrmaekion as M. tarrhunense (Karsch, 1881) comb. nov.

Two new species of the genus Nemaspela Šilhavý, 1966 (Opiliones: Nemastomatidae) from Georgian caves

Abstract

Two new cavernicolous harvestmen species, Nemaspela sakavria sp. nov. from Sakavria Cave and Nemaspela sakinule sp. nov. from Sakinule (Nikortsminda) and Melia (Nikortsminda) caves, are described from the Racha karst massif in the Racha-Lechkhumi and Kvemo Svaneti region of western Georgia. A differential diagnosis is provided in relation to morphologically similar species, as well as a key for the identification of species of the genus Nemaspela. This study provides the first molecular genetic data for the genus Nemaspela. Pairwise genetic distances for the COI-5P barcode region showed clear differentiation between the two new and one unidentified Nemaspela species examined.
