new species

Type material:
Holotype
male,
paratype
male and
paratype

Portugal
,
Coimbra
,
Paúl
de Arzila NR, meadow with few
Populus sp.
, about
100m
from a small river,
23.X.2006
,
L. Crespo
leg.; deposited in KBIN.
Etymology:
The name is an adjective and is Latin for a natural from
Coimbra
, the city where
P. conimbricensis
was first found.
Diagnosis:
The new species is closely related to
Parapelecopsis nemoraloides
(O.P.-Cambridge, 1884) and
P. nemoralis
(Blackwall)
. Males differ by the cephalic lobe being longer than wide, the wider sulcus, the relatively shorter dorsal and ventral apophyses of the palpal tibia and the wider terminal part of the embolus; females differ by the more anterior position of the insemination ducts.
Remarks:
The genus
Parapelecopsis
was created by Wunderlich in 1992 and, according to
Platnick (2009)
, comprises three species:
Parapelecopsis nemoralis
(Blackwall, 1841)
(
type
species),
P. nemoralioides
(O.P.-Cambridge, 1884), and
P. mediocris
(Kulczyn'ski, 1899). The first two are widely distributed in the Palearctic region and the third one is only known from
Madeira
. According to
Wunderlich (1985)
,
Pelecopsis nemoralis
and
P. nemoralioides
have identical bulbs and variable height of the prosoma in both species; they can only be differentiated by the shape of the palpal tibia. He further suspects
P. mediocris
to be a junior synonym of
P. nemoralioides
. Figures of the prosoma of
P. nemoralis
and
P. nemoralioides
have been published by
Simon (1884
, figs 529–535),
Tullgren (1954
, figs 80e–f),
Wiehle (1960
, figs 61–71),
Locket
et al.
(1974
, figs 52A, C, F),
Roberts (1987
, figs 23i, 25a) and
Heimer & Nentwig (1991
, fig. 621). All show a large, rounded cephalic tubercle and a relatively small sulcus, clearly different from the material now discovered in
Portugal
. There are also differences in the male palp and the female epigynum. The creation of a new species is therefore clearly justified.
Another species is here transferred to the genus
Parapelecopsis
:
Parapelecopsis lunaris
(
Bosmans & Abrous 1992
)
new combination
, from the north of
Algeria
. The species has all the characters of the genus: spineless tibiae, a cephalic lobe carrying the PM, one trichobothrium on the male palpal tibia, a long tegulum, a short spiral embolus and an anterior position of the spermathecae.
Description:
Male: Measurements: Total length 1.7–1.8; prosoma 0.70–0.83 long, 0.56–0.60 wide. Colour: Prosoma brown with darkened striae, thoracic part somewhat paler; legs yellow brown; abdomen greyish, in males with dark brown, pitted scutum, Prosoma (
Figs 80–81
): With small, flattened tubercle carrying the PM, longer than wide, with strong concavity between the AM and the PM and with very large sulcus behind the PL. Eyes: a = b = 1, c = 0.75, d = 3. Chelicerae: Fang groove with three promarginal and three smaller retromarginal teeth; stridulating file with 8 inconspicuous ridges. Sternum: With few punctures, smooth in the middle getting rugose towards the margins. Legs: All tibiae spineless. Tb Mt I = 0.43; Tb Mt IV absent. Palp (
Figs 82–84
): Tibia with large, triangular dorsal and retrolateral apophyses; tegulum ventrally strongly produced with large protegular process; suprategular apophysis strongly developed, U-shaped; embolic division with elongated tailpiece, embolus wider than tailpiece, compact, spirally coiled describing one circle, terminally pointed.

): With rectangular plate with curved lateral margins.
Vulva (

): Spermathecae rounded, separated by 1.5 their diameter; insemination ducts wide, nearly touching in the middle, anteriorly trespassing the base of the spermathecae.
