Color variation.
Color of antennae, palpomeres, femora, and tibiae varied from medium brown to dark brown or even black among different individuals (
Figs 22-23
,
36
-
41
).
Geographical distribution.
Fig. 158
. Known only from eastern Afghanistan, Pakistan, and northern India.
Remarks.
Mensural data cited in the description were obtained from type and cotype specimens examined. The name
Chlaenius agilis
Chaudoir was once treated as a junior synonym of
Chlaenius latro
LaFerte-Senectere
(
Csiki 1931
,
Kirschenhofer 1997
). However, in his work,
LaFerte-Senectere
(1851)
did not provide a specific description of
Chlaenius latro
. This means that
Chlaenius latro
LaFerte-Senectere
is a
nomen nudum
, and therefore, unavailable.
Kirschenhofer (2005)
considered
Chlaenius nuristanus
Jedlicka
to be a junior synonym of
Chlaenius anchomenoides
Bates. We have examined the types and/or cotypes of
Chlaenius agilis
Chaudoir,
Chlaenius anchomenoide
s,
Chlaenius nuristanus
and its aberration
Chlaenius nuristanus
a.
rubridipes
, and found no significant differences between them, except for variation in the color of antennae and legs. The aedeagi are abruptly bent near the base in all dissected males (
Figs 124
,
139, 141, 143
).
Mandl (1972: 104)
assigned
Chlaenius anchomenoides
to genus
Stenochlaenius
. Based on the pubescent elytral intervals and incomplete elytral basal margin in members of
Chlaenius anchomenoides
, we do not agree with this assignment.
