Inventory of the spiders (Araneae) of the border region of northern Greece with Albania and FYR Macedonia

In May 2016 an inventory of the spider fauna was carried out in the border region of Greece, Albania and Macedonia. In the course of two weeks 33 sites were visited and sampled, resulting in 244 species of 31 families amongst which 25 species recorded for Greece for the first time (Comaroma simoni Bertkau, 1889, Araneus triguttatus (Fabricius, 1775), Araniella displicata (Hentz, 1847), Cyclosa oculata (Walckenaer, 1802), Gibbaranea ullrichi (Hahn, 1835), Clubiona marmorata L. Koch, 1866, Clubiona subtilis L. Koch, 1867, Cicurina cicur (Fabricius, 1793), Leptodrassex memorialis (Spassky, 1940), Centromerus lakatnikensis (Drensky, 1931), Kratochviliella bicapitata Miller, 1938, Sintula corniger (Blackwall, 1856), Tenuiphantes flavipes (Blackwall, 1854), Theonina kratochvili Miller & Weiss, 1979, Trichoncus saxicola (O. P.-Cambridge, 1861), Walckenaeria acuminata Blackwall, 1833, Walckenaeria cucullata (C.L. Koch, 1836), Walckenaeria nudipalpis (Westring, 1851), Alopecosa taeniata (C.L. Koch, 1835), Zora manicata Simon, 1878, Evarcha michailovi Logunov, 1992, Dipoena braccata (C.L. Koch, 1841), Robertus frivaldszkyi (Chyzer, 1894), Theridion betteni Wiehle, 1960, Heriaeus zhalosni Komnenov, 2017). The females of two species are described for the first time: Nomisia levyi Chatzaki, 2010 and Erigonoplus simplex Millidge, 1979. The earlier suggestion of the synonymy of Pardosa tatarica with Pardosa atomaria is repeated. Theridion betteni Wiehle, 1960 is reported as new for Albania.
