Taxonomic revision of the family Eosentomidae (Hexapoda: Protura) from Japan 2701 Author Nakamura, Osami text Zootaxa 2010 2010-12-03 2701 1 109 journal article 1175­5334 Eosentomon topochi Imadaté 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).
