Eosentomon kimum Imadaté  

Fig. 35

Eosentomon kimum Imadaté, 1964a: 43   , figs. 5–12; Imadaté, 1974b: 272, fig. 137.

Specimens examined. Holotype male, NSMT – Ap 4, Otoineppu, 20-X-1962, G. Imadaté leg.; 2 males, NSMT – Ap 121, Nishishibetsu, Shibetsu –shi, Hokkaido, 3-IX-1969, K. Niijima leg.  

Additions to description. On head, seta rs simple, slightly thicker and shorter than sr ( Fig. 35A). On maxillary palpus ( Fig. 35B) sensillum md longer than ml. Mandible rounded terminally ( Fig. 35C). On hind tarsus ( Fig. 35D) D2 and D4 spine-like, more slender than D5. On abdominal tergite VIII ( Fig. 35E) P1a' without basal dilatation and anterior to P2, P2a linear.

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   .

Distribution. Japan (Hokkaido).
