Diagnosis.—
Pocadicnemis pumila
is distinguished from
P. a m e r i c a n a
by the straight median apophysis (MA) of the male palpus (
Fig. 29
).
Distribution.—
Widespread in North
America
.
Remark.—
Pocadicnemis pumila
is very similar to
P. americana
(see
Paquin & Dupérré 2003
, figs
1206–1208
), and these two species are commonly found in the same habitat.
Millidge (1976)
, who described
P. americana
, gave characters to distinguish males and females of the two species, but examination of several specimens and comparison with his illustrations led us to the conclusion that females are impossible to separate. Therefore, the present records are from males only. We rely on the shape of the median apophysis to distinguish the two species (straight in
P. pumila
and curved in
P. americana
see
Fig. 30
, and
Millidge 1976
: figs 24 and 40) but we are not convinced that these represent disctinct species. A few specimens examined (omitted here) could have been placed in
P. pumila
based on examination of the right palp and in
P. americana
with the left palp. However, the two species are actually valid and we report the present records on that premise.
