On the Discontinuous Distribution in Some Opiliones

[摘要] References(16)Cited-By(1)1. This paper is concerned with the discontinuous distribution in some Opiliones.2. Caddo agilis BANKS (Caddoinae) occurs disjunctively in Japan and in the north-eastern area of North America.3. Japanese Cladolasma parvula SUZUKI (Nemastomatidae) strikingly resembles the North American Dendrolasma mirabilis BANKS, both of which showing the distribution pattern of amphipacific disjunction.4. Crosbycus dasycnemus (CROSBY) (Nemastomatidae) so far known from the north-eastern area of North America is newly recorded from several localities of Japan. The populations of the both areas are so similar that no specific distinction is obtained.5. All the species discussed are regarded as survivors.
