Etymology. Named after the Portuguese arachnologist Luis Crespo, our friend, who helped to discover this species.

Diagnosis. The species is characteristic by the cymbium bent around tegulum ( Fig. 3N View FIGURE 3 ), tegulum wider than long and extremely long embolus ( Fig. 5F View FIGURE 5 ). The embolus is very long also in H. dolanskyi sp. nov. and H. tavirensis , but these species possess conductor, in H. crespoi sp. nov. it is absent. The vulva is similar to that of H. algarvensis , but it lacks two pockets of whitish tissue in front of the anterior arc, and is less sclerotised, the only obviously sclerotised part of the anterior arc is the median rod ( Fig. 8C View FIGURE 8 ).

Description. Male (holotype). Carapace pale brown, matting ( Fig. 1N View FIGURE 1 ). Sternum brown-yellow, matting. Chelicerae pale brown. Legs are pale yellow, pedipalps darker. For measurements and leg spination see the Table 1 View TABLE 1 . Relative leg length: IV>I>II>III. Cymbium slightly bent around the bulbus, with elongated distal part ( Fig. 3N View FIGURE 3 ), and slightly concave basal half of the prolateral side. Tegulum wider than long ( Fig. 5F View FIGURE 5 ). Conductor absent. Embolus dark, extremely long, slightly undulated, directing to the side, the base is bent in 180° angle. Opisthosoma cylindrical, whitish.

Female (paratypes). All somatic characters as described for the male. The vulva is of the type algarvensis (see Materials and Methods) ( Fig. 8C View FIGURE 8 ).The vulva is relatively small and only slightly sclerotised. The median rod is very weak. The posterior diverticle is a rudimentary spherical sclerotised spot.

Size range. Male carapace length 1.6–2.3 mm (1.9±0.18, N=8), female carapace length 1.53–1.86 mm (1.72±0.17, N=3).

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 small mountain range in southern Portugal.
