Remarks.
The
holotype
was not in good condition. Therefore, I examined two other specimens from Nishishibetsu,
Hokkaido
collected by Dr. K. Niijima, but they were also not in good condition so that some characters could not be observed.
I examined other
two specimens
labeled as "
E. kimum
?" reported in
Imadaté & Ohnishi (1979)
:
1 male
from
Nanatsunuma
(
Hokkaido
,
23-VIII-1977
,
J. Ohnishi
leg.), and
1 male
from
Shizunai
(
Hokkaido
,
5-VIII-1975
,
T
.
Satoh
leg.), both identified by the late
Dr. Imadaté
(
Imadaté’s Proturan Collection No.
1139 2 and
1137 in
NSMT
, respectively).
They
also were not in good condition.
However
, they were different from
E. kimum
in the shape and position of
P1a
, which was sensillum-like and on the same level with
P1–P2
on abdominal tergites
V
–
VI
(delicate and posterior to
P1–P
2
in
E. kimum
).
Hence
these specimens are presumably an undescribed form similar to
E. kimum
.
As
they were males and not in good condition, it is preferable to leave this form undetermined until females can be obtained
.
