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
.
