Material examined. Portugal, Guarda, Seia, Casa do Loureiro , 40.4334°N, 7.7005°W, 415 m a.s.l., 19 july 2023, Ferreira & Cruz-Oliveira, 1 deutonymph (DNA barcoded; Voucher Id: BGE _00109_E01) GoogleMaps ; Viana do Castelo, Melgaço, Aldeia de Pontes , stream between the houses, 41.9887°N, 8.1634°W, 720 m asl., 20 Aug. 2024, leg. Ferreira, Girão & da Silva, 1♂ dissected and slide mounted (DNA barcoded; Voucher Id: BGE _00580_E03; RMNH) GoogleMaps ; Viana do Castelo, Melgaço , Porto Ribeiro, Watermill and medieval bridge of Lamas de Mouro , 42.0446°N, 8.2030°W, 865 m asl., 19 Aug. 2024, leg. Ferreira, Girão & da Silva, 1♂ (DNA barcoded; BGE _00580_D03) GoogleMaps .

Remarks: Morphological analysis revealed that in regard to the shape of palp (as illustrated in Fig. 6A–B), postgenital plate longitudinally distinctly wider than long (length/width <1), III–IV-leg-5 with prominent distolateral extension ( Fig. 6C) and the tip of anterior ramus of ejaculatory complex indented with laterally rounded, posteriorly slightly pointed extensions, Portuguese males match the description S. denticulatus . Genetic data indicate that examined specimens form a unique BIN (BOLD:AFW4926).

Distribution. Western Palaearctic. New for Portugal.
