Here we report four spider findings that are new for the Province of South Tyrol (northern Italy), with two of them being new for Italy. All spider species were found on extensively grazed dry pastures located in the inner-alpine dry Vinschgau valley and in or close to the Italian LT(S)ER area „Val Mazia/Muntatschinig“ (LTER_EU_IT_097).
The jumping spider Pellenes lapponicus (Sundevall, 1833) (Salticidae) and the crab spider Psammitis bonneti (Denis, 1938), both new to South Tyrol, were found on alpine dry grasslands at 2500 m a.s.l. above the localities of Schluderns/Sluderno and Obertels/Tels di Sopra (Tanas, Laas/Lasa).
The velvet spider Eresus sandaliatus (Martini & Goeze, 1778) (Eresidae) was also found on alpine dry grasslands at 2500 m on the adjacent crest above the localities of Muntatschinig and Matsch (both Mals/Malles Venosta). The yellow sac spider Cheiracanthium campestre Lohmander, 1944 (Cheiracanthiidae) was found in sub-alpine dry grasslands at 1500 m close to Planeil and Muntatschinig (both Mals/Malles Venosta). These two spiders are new recordings for both South Tyrol and Italy.
