Crop Research Institute, Prague . Etymology. Named after the Czechoslovak arachnologist Stano Pekár, our friend who helped us to collect material for this study. Diagnosis. The smallest and more gracile Portuguese Harpactea species. It resembles H. gaditana , H. fageli and H. henriquesi sp. nov. by slightly elongated unmodified cymbium ( Fig. 3D ). It can be distinguished from the former species by spherical tegulum, no conductor and long regularly curved embolus, transversal in respect to tegulum ( Fig. 4D ). The reduced (small, only slightly sclerotised and without spermathecae) vulva resembles H. algarvensis , H. tavirensis and H. crespoi sp. nov. but it can be distinguished from these species by narrow posterior transversal bar bearing two furrows ( Fig. 6C ). It co-occurs with H. minoccii , from which it differs by smaller and lighter body. Description. Male ( holotype ). Carapace yellow-orange, head region darker, matting ( Fig. 1D ). Sternum yellow, matting. Chelicerae brown. Legs yellow, femora I and pedipalps darker. For measurements and leg spination see the Table 1 . Relative leg length: IV>I>II>III. Cymbium with only slightly elongated distal part ( Fig. 3D ). Tegulum large, longer than wide ( Fig. 4D ). Conductor atrophied. Embolus dark, long, regularly bent, directing to the side. Opisthosoma cylindrical, whitish. Female. All somatic characters as described for the male. The vulva is of the type pekari (see the Material and Methods). It is very reduced and does not possess any posterior diverticle ( Fig. 6C ). Variability. Male carapace length 1.33–1.84 mm (1.58±0.14, N=21), female carapace length 1.51–1.60 mm (1.54±0.04, N=4). Ecology. Adults are found in early spring in leaf litter and under stones on humid northern slopes with Quercus ilex and Juniperus turbinata bush. Distribution. Known only from the valley of the river Guadiana near Mertola in southern Portugal .
