Altella aussereri, Mimetus laevigatus, and Trichoncyboides simoni (Araneae: Dictynidae, Mimetidae, Linyphiidae), three species of spiders new for Slovakia

Three species of spiders (Araneae), Altella aussereri Thaler, 1990, Mimetus laevigatus (Keyserling, 1863), and Trichoncyboides simoni (Lessert, 1904), are reported from Slovakia for the first time. These new records originate from southern Slovakia. The record of A. aussereri provides new data on the distribution and natural history of this range-restricted species of very high conservation value. The records of M. laevigatus and T. simoni in Slovakia extend their known distribution in Central Europe. Characteristic features, pictures of the habitus, copulatory organs, and habitats are presented.
