description: Zodarion weissi Deltshev & Naumova sp. n.
Figs 61–75.
Types. Holotype: ♂ (NMNHS-Zod-0004.1), BULGARIA: Sofia Mt., Kremikovtsi ward, N42.7882 ˚, E23.4812 ˚, 645 m, 23.06.2019, M. Naumova leg. Paratypes: 2♂, 2♀ (NMNHS-Zod-0004.2) same data as the holotype.
Comparative material examined. Zodarion abantense Wunderlich, 1980 (♂ holotype, 1♀ paratype (SMF 30055, 58853), TURKEY, Bolu village, Abant Mountains, 29.04– 20.05.1976, H. Korge leg.; Z. pirini (1♂, 2♀ (IBER), BULGARIA, Eastern Rhodopes Mts, Blagun village, N41.3698 ˚, E25.7515 ˚, 423 m, 24.05.2018, M. Naumova leg.; Z. turcicum Wunderlich, 1980 (1♂ (IBER), BULGARIA, South Black Sea coast, Primorsko resort, N42.2544 ˚, E27.7487 ˚, 3 m, 27.04– 07.06.2016, T. Teofilova, T. Ljubomirov & N. Karaivanov leg.).
Diagnosis. Zodarion weissi sp. n. belongs to the germanicum species group (sensu Bosmans 2009) and resembles Z. aurorae Weiss, 1982. Males differ by the following traits: tegular projection elongated triangular in lateral view in Z. weissi sp. n., vs. oblong with a broad rounded tip in Z. aurorae; basal tegular bulge reaching to the half of the tegular projection in Z. weissi sp. n. (Figs 63–65, 71, 72), vs. reaching more than 2/3 of the tegular projection length in Z. aurorae (see in Weiss 1982: 80, fig. 1) in lateral view. Females differ as follows: posterior margin of the epigynal plate with triangular incision with broad and shallow hood, 2.5–3 times wider than long in Z. weissi sp. n. (Figs 68–70, 73–75), vs. narrow and deep anterior hood, clearly longer than wide in Z. aurorae (see in Weiss 1982: 80, fig. 3).
Etymology. The species is dedicated to Ingmar Weiss (Grafenau, Germany) a well-known arachnologist who has great contribution to araneological research in Romania.
