Eosentomon topochi
Imadaté, 1964a: 56
, figs. 24–27;
Imadaté, 1974b: 293
, figs. 152–153.
Specimens examined.
The
holotype
was not found; therefore, other specimens listed as "
E. topochi
?" in
Imadaté & Kinjo (1985)
and
Imadaté & Ohnishi (1979
,
1993
) were studied.
Remarks.
One male from Pankenai (NSMT–Ap 227,
Hokkaido
,
3-X-1974
, H. Tamura leg., site No.
11 in
Imadaté & Ohnishi (1979))
, was not in good condition and characters could not be observed. Females from Okoppe (
Hokkaido
,
6-VIII-1979
, J. Ohnishi leg., Imadaté’s Proturan Collection No. 8054 1, site No.
54 in
Imadaté & Ohnishi (1993))
and Soranuma–dake (
Hokkaido
,
22-VII-1979
, O. Nakamura leg., in my collection, site No. 97a in
Imadaté & Ohnishi (1993))
were also in poor condition. However, the female caput processus in both specimens was visible; it is almost straight, being different from the S-shaped sclerotization on the processus sternalis in the original description of
E. topochi
.
In
one female
from
Hagurosan
(
Yamagata
,
3-XI-1977
,
K. Shirahata
leg.,
Imadaté’s Proturan Collection No.
4111 31, site
No.
111 in
Imadaté & Kinjo (1985))
, the foretarsus possessed sensillum
b'1
, abdominal tergite
VII
had three pairs of anterior setae (
A2, A4, A5
) and abdominal sternite VIII possessed two anterior and seven posterior setae.
These
characters were different from the original description of
E. topochi
.
Therefore
, these females are certainly different forms
.
Distribution.
Japan
(
Hokkaido
and Honshu).
