Etymology. Named after the Czechoslovak arachnologist Stanislav Korenko, our friend who helped us to collect material for this study.

Diagnosis. It differs from most Iberian Harpactea species by almost straight dorsal side of cymbium ( Fig. 3H View FIGURE 3 , like in H. magnibulbi ), and relatively short embolus (approximately of the same length as conductor, Fig. 4H View FIGURE 4 ). It resembles H. magnibulbi ; males differ by the distance between the anterior cheliceral teeth, that is 1.5× longer than the distance between the teeth in the posterior row ( Fig. 2H View FIGURE 2 , in H. magnibulbi the distance between the dorsal teeth is the same as the distance between the ventral teeth, Fig. 2G View FIGURE 2 ); the position of the dorsal distal tooth that is between the ventral teeth (in H. magnibulbi it is next to the posterior basal tooth), and by the shape of embolus, which is thinner ( Fig. 4H View FIGURE 4 ), S-shaped on its distal end; females differ by anterior arc with lobes bent backwards on its prolateral edges and absence of posterior diverticle rudiment ( Fig. 8B View FIGURE 8 ).

Description. Male (holotype). Carapace yellow, matting ( Fig. 1H View FIGURE 1 ). Sternum yellow, matting, with long hair on the edges. Chelicerae yellow brown. Legs yellow brown, pedipalps ferruginous. Measurements and spination are shown in the Table 1 View TABLE 1 . Relative leg length: IV>I>II>III. Cymbium with very elongated distal part ( Fig. 3H View FIGURE 3 ), and very concave prolateral side. Tegulum large, longer than wide ( Fig. 4H View FIGURE 4 ). Conductor regularly bent, flattened, tapering. Embolus dark, parallel to conductor but more bent, only slightly longer than conductor, flattened, its end is S-shaped. Opisthosoma cylindrical, whitish.

Female. All somatic characters as described for the male. Vulva is of the type algarvensis (see Materials and Methods) ( Fig. 8B View FIGURE 8 ).

Variability. Carapace length 1.5–2.2 mm (both sexes) (N=33).

Ecology. It lives in leaf litter in shaded Quercus coccifera forests. Females lay eggs in early spring. The presence of independent juveniles together with mothers with egg sacs suggests a possible two-year life cycle.

Distribution. Forests around the south Portuguese city of Carrapateira.
