Harpactea dolanskyi Řezáč sp. nov. (Figs 1L, 2L, 3L, 5D, 9) Type material. Holotype. ♁, Mertola, Mertola, 37.643, -7.661, Eucalyptus trees, 30 March 2013, leg. M. Řezáč, coll. National Natural History Museum, Prague, code P6A 7386. Paratypes. Mertola, Mertola, 37.643, -7.661, Eucalyptus trees, 3 ♁♁, 30 March 2013, 2 ♁♁, 20 March 2022, leg. M. Řezáč, coll. Crop Research Institute, Prague. Etymology. Named after the Czech arachnologist Jan Dolanský, our friend who helped us to discover this species. Diagnosis. This species is characterised by long thin S-shaped conductor and embolus (Fig. 5D). Its bulbus is similar to that of H. tavirensis, but tegulum is longer than wide, and embolus is more detached from tegulum. It possesses the cheliceral type algarvensis (Fig. 2L). In contrast to the other two representatives of this cheliceral type, H. algarvensis and H. krejcii sp. nov., its posterior basal cheliceral tooth is shifted more basally (it is not next to the anterior basal tooth, Fig. 2L). The male pedipalpal tarsus is only slightly elongated, it exhibits, like in H. algarvensis, no special modifications (Fig. 3L). Description. Male (holotype). Carapace olive brown, matting (Fig. 1L). Sternum yellow-brown, matting. Chelicerae brown. Legs yellow-brown, anterior legs and pedipalps darker. For measurements and leg spination see the Table 1. Relative leg length: IV>I>II>III. Cymbium with elongated distal part (Fig. 3L), and concave basal half of the prolateral side. Tegulum large, longer than wide (Fig. 5D). Conductor thin, relatively long, S-shaped. Embolus dark, very long, thin, S-shaped, directing distally. Opisthosoma cylindrical, whitish. Female unknown. Variability. Male carapace length 1.9–2.5 mm (2.2±0.2, N=4). Ecology. It was found in relatively dry leaf litter under Eucalyptus trees on a northern slope in early spring. Distribution. Known only from the type locality, in the valley of Guadiana river, near Mértola, in southern Portugal.
