Types
The
type
specimens, representing
Teg. picta
and
Teg. pusilla
, could not be traced in the
MNHN
. Several specimens (
MNHN
) from the
type
locality of
E. picta
(Guadarrama)
were determined by E. Simon.

Diagnosis:
Eratigena picta
and the closely related
E. balearica
have the dorsal branch of the RTA distally elongated and bent posteriad (all other species of
Eratigena
gen. nov.
with differently shaped RTA), a short dorsal spike at the male palp tibia (absent in
E. inermis
,
E. vomeroi
,
E. arganoi
,
E. sardoa
,
E. sicana
,
E. hispanica
,
E. herculea
,
E. incognita
, and
E. feminea
), a moderately to strongly elongated distal portion of the conductor (not elongated in
E. inermis
,
E. vomeroi
,
E. atrica
,
E. agrestis
, and
E. fuesslini
), the distal margin of conductor entirely folded (shared character with
E. herculea
,
E. hispanica
,
E. arganoi
,
E. sardoa
, and
E. sicana
), and an epigyne with distinct atrial cavity (shared character with
E. agrestis
and
E. fuesslini
, absent in all other
Eratigena
gen. nov.
species). Male
E. picta
can easily be separated from the closely related
E. balearica
by having the distal portion of conductor much more elongated, the more convoluted terminal end of the conductor, and the relatively much shorter male palp tibia. Females of
E. picta
can be separated from
E. balearica
females by the shape of the transparently visible CD on the epigynal plate and the very differently shaped vulvae.
Description
Redescriptions of
E. picta
were, at least partly, provided by
Dahl (1931: 32
, 33 sub
Teg. picta
, 41, 42 sub
Teg. pusilla
) and
Jones (1984)
. Drawings were also provided by
Brignoli (1971b)
.
Distribution
Reported from all western European countries. The eastern boundary of distribution may run through western
Germany
and
Switzerland
. Records from
Hungary
, the Balkan region, and
Russia
may be doubtful (see e.g.
Deltshev, 2008a
).
Discussion
In
E. picta
incredibly great variation in size can be observed, which also influences the genital structures (
Fig. 12R–S
). Such variation is also found in other related species (e.g.
Simon, 1937: 1003
;
Kraus, 1955: 379
;
Bolzern
et al
., 2008: 763
).
Together with
E. balearica
,
E. picta
forms the ‘
Eratigena
picta-
group’. This is in contrast to previous polyphyletic concepts, which were based on that of
Simon (1937)
who grouped
E. picta
with
Aterigena soriculata
and
Aterigena ligurica
(all sub
Tegenaria
).
