Remarks on synonymy:
Lepthyphantes bacelarae
was described by
Schenkel (1938)
from a single female from Sintra (
Portugal
). The species has never been cited since then and the
type
material was not examined. The description is accompanied by good illustrations of the epigynum in ventral and lateral view, which allowed
Telfer
et al
. (2003)
to identify females collected in Tapada de Mafra as
L. bacelarae
. The females were accompanied by the unknown male and this allows us to describe it and classify the species in one of the new genera that recently have been created for species previously placed in
Lepthyphantes
. The male palp (
Fig. 57
) appears to be very similar to the one of
Lepthyphantes obscurus
(
Fig. 64
), in having a cymbium with a conical tubercle and an elongated lamella. The epigynum also shows corresponding characters: the absence of lateral lobes and the short insemination ducts.
Lepthyphantes obscurus
is the
type
species of the genus
Obscuriphantes
and
Lepthyphantes bacelarae
is hereby transferred to
Obscuriphantes
.
The first author was also able to examine the
type
material of
Lepthyphantes ollivieri
described by Denis (1957) from the French Pyrénées, only known from the female. The epigynes of
L. bacelarae
and
L. ollivieri
are identical and
L. ollivieri
becomes a junior synonym.

Diagnosis:
The species is closely related to
Obscuriphantes obscurus
, especially the males and these can have been misidentified in the past. Males are distinguished from
O. obscurus
by the more conical cymbial tubercle and the shorter lamella (
Fig. 57
versus fig. 64), females are much easier distinguished by the rounded scape in
O. bacelarae
(
Figs 59, 60
), angular in
O. obscurus
(
Fig. 66
).
Description:
Male: Measurements: Total length 1.9–2.0, prosoma 0.90–0.92 long, 0.74–0.76 wide. Colour: Prosoma brown suffused with chestnut brown; legs pale yellowish brown; abdomen with dorsal pattern of brown, grey and white. Legs: Fe I pl, Fe II–IV spineless; Ti I 2 d pl rl, Ti II 2 d rl, Ti III–IV 2 d; Mt d; Tb Mt I = 0.85. Palp (
Figs 57, 58
): Femur with long dorsal spine, twice as long as its diameter; tibia with short dorsal spine, as long as its diameter; cymbium with strong conical tubercle; basal branch of paracymbium with two hairs, with basal tooth, distal branch widened, terminally deeply incised; lamella bifid, consisting of two unequally elongated, pointed branches.
Female:
Measurements: Total length 2.2; prosoma 0.82 long, 0.66 wide. Colour and spine disposition as in the male. Epigynum (
Figs 59–62
): Scape with narrow stalk, in ventral view much wider than long, in an oblique position, in posteroventral view oval and with deep posteromedian incision in which fits the scape. Vulva (
Fig. 63
): Spermathecae small and oval, with lateral lobe; insemination ducts short, running from the spermathecae to the anterior parts of the scape.

Distribution:
The species is known from several localities in Central
Portugal
and one in the French Pyrenees (Denis 1957), as
Lepthyphantes ollivieri
. This species is expected to occur in
Spain
.
Habitat
type
:
All material was collected by beating or sweeping vegetation, indicating the species lives on trees, like its congener
Obscuriphantes obscurus
.
Phenology:
Adult females were collected from May to September, and the single male in May.
