Type material.
Holotype
of
Placusa vaga
:
♀
, “
Sta. Cruz
Mts.
Cal.[ifornia]”, “
vaga
Csy.
”, “TYPE USNM 39576” (red label), “CASEY bequest 1925” (
NMNH
).
Holotype
of
Pseudota cornicula
:
♀
, “Metlakatla, B.[ritish] Col.[umbia] Keen”, “
cornicula
Csy.
”, “TYPE USNM 39161” (red label), “CASEY bequest 1925” (

Diagnosis.

Discussion.
The
holotype
of
Ps. cornicula
agrees with the
lectotype
of
Pl. vaga
in external characters and in the shape of the spermatheca.
Casey (1911a)
admitted that he was unable to examine the tarsal formula of the
holotype
of
Ps. cornicula
(it is in fact 44 5). This may explain why he failed to recognize that the species belonged to
Placusa
(tribe
Placusini
).
Distribution.
Placusa vaga
is known from
British Columbia
and
California
.
