New synonymy
Justification of the synonymy.
The epigynum of
A
.
captator
looks similar to the epigynum of the
subterraneus
-group of
Zelotes
, as illustrated for
Zelotes subterraneus
(C. L.
Koch, 1833
)
,
Zelotes fratris
Chamberlin, 1920
and
Zelotes sula
Lowrie & Gertsch, 1955
: epigynum with paired anterior comma-like margins, with L-shaped lateral margins and posterior margin with a median protrusion (compare
Fig. 5
with
Platnick & Shadab 1983
: figs 4, 8, 11, 16). Moreover,
A
.
captator
has small, globular spermathecae that are also similar to that of the above-mentioned species (compare
Fig. 5
with
Platnick & Shadab 1983
: figs 4, 8, 11, 16). Based on these observations, I propose to consider
Aracus
as a junior synonym of
Zelotes
, in contrast to
Deeleman-Reinhold (2001)
, who doubted
Aracus
as a senior synonym of
Haplodrassus
Chamberlin, 1922
. Females of
Haplodrassus
species are distinct from that of
Aracus
by having paired lateral epigynal arms (
Platnick & Shadab 1975
: figs 3, 7). The proposed synonymy has resulted in a new combination (see below).
