Abstract

Knowledge of the cosmopolitan land planarian Bipalium kewense is briefly reviewed. A neotype and paraneotypes are designated. External morphology and internal anatomy of the species are redescribed. Karyological studies on B. kewense reveal a diploid chromosome complement of 16; one subtelocentric, three submetacentric and four metacentric chromosome pairs. Taxonomy of B. kewense is revised and full synonomy provided. New synonomies include Placocephalus isabellinus Geba and Bipalium costaricensis Hyman. Species that phenetically resemble B. kewense are divided into three groups primarily on the basis of stripe pattern and cutaneous musculature. A differential diagnosis distinguishing B. kewense from taxa in these groups is provided. Present distribution of the species is mapped. New records are reported from Barbados, Colombia, Costa-Rica, El Salvador, Indonesia, Madagascar, Malaysia, Mauritius, Mexico, Puerto Rico, Tahiti, Taiwan and Zimbabwe. Worldwide B. kewense exhibits a disjunct distribution pattern. In Australia and in the United States a similar pattern of occurrence is evident. The species appears to be dispersed with rooted plants. The natural range of B. kewense extends from Vietnam to Kampuchea, possibly extending to Malaysia. Elsewhere it has been introduced by man. The bipaliid fauna of Vietnam, to which B. kewense belongs, appears to have closer phenetic affinities with the faunas of adjacent southern rather than northern regions.
