Discussion.
Claustropyga simplicis
was previously known only from the
holotype
and three
paratype
males from Ontario. The new specimen from British
Columbia
differs from the
types
by having some of the ventral setae of the gonocoxa shorter and curved, resembling the setae of some other species of
Claustropyga
, e.g.
C. sajanica
(Mohrig & Antonowa)
, and by having sharp-angled lateral shoulders on the tegmen, not dissimilar to some other species of
Claustropyga
, e.g.
C. sajanica
and
C. ctenophora
. So far as the latter character is concerned, the difference between the new specimen and the
holotype
(cf.
Hippa, Vilkamaa and Mohrig 2003
) is rather striking, but we believe that it is because the aedeagus-tegmen complex is not in an identical position on the mounts. A similar variation is also known in some other species, e.g.
C. ctenophora
(cf.
Hippa, Vilkamaa and Mohrig 2003
, Fig. 11). Except for the slight difference in the character of the ventral setae mentioned above, the gonostylus is identical in the
types
and the British
Columbia
specimen, and we are rather certain that they all belong to same species.
