1 ♁ Paratype. Moura, Serra da Adiça , 37.978, -7.294, Quercus coccifera bush, 27 March 2013, leg. M. Řezáč, coll. Crop Research Institute, Prague GoogleMaps .

Etymology. Named after the mountain range Serra da Adiça, the type locality of this species.

Diagnosis. Harpactea adicensis sp. nov. resembles H. magnibulbi and H. korenkoi sp. nov. by the shape of copulatory organs, in particular by almost straight dorsal side of cymbium ( Fig. 3I View FIGURE 3 ), but it can be distinguished from these species by absence of conductor and the flattened embolus directing distally, growing from the middle of a collar on the terminal part of tegulum ( Fig. 5A View FIGURE 5 ). Also, the morphology of male chelicerae is unique. The arrangement of teeth is of usual Harpactea type (two teeth in posterior row and two teeth between them in anterior row, but the fang is with tooth on its frontal side.

Description. Male (holotype). Carapace olive brown, matting ( Fig. 1I View FIGURE 1 ). Sternum yellow-brown, matting. Chelicerae brown.Legs brown yellow, pedipalps brown. For measurements and leg spination see the Table 1 View TABLE 1 . Relative leg length: IV>I>II>III. Cymbium with elongated distal part ( Fig. 3I View FIGURE 3 ), and concave prolateral side. Tegulum large, longer than wide, terminated by collar surrounding the base of the embolus ( Fig. 5A View FIGURE 5 ). Conductor atrophied. Embolus dark, regularly bent, flattened, the widest in the middle, directing distally. Opisthosoma cylindrical, whitish.

Female. Unknown

Ecology. Adults were found in early spring in leaf litter of Quercus coccifera forests on northeastern slopes.

Distribution. So far known only from Serra da Adiça, a mountain range in southern Portugal.
