Type data. Indonesia , North Sumatra Province , Medan, from Homo sapiens L. ( L. deliense ); China , Taiwan Province, Penghu Islands, from Rattus exulans (Peale) ( L. deliense sinense ); China , Hainan Province , Paracel Islands, from Rattus tanezumi Temminck [= Rattus flavipectus (Milne-Edwards) ] ( L. deliense microsetosa ). Remarks. Vercammen-Grandjean and Langston (1976) give fPp = N/N/BNB for L. deliense in the text of description. This is an obvious error, because in their figures, identification key, and the section concerning species grouping, fPp = N/N/BNN. Subspecies L. deliense sinense and L. deliense microsetosa have no significant differences from the nominate subspecies. Their diagnoses do not allow identification of new materials. Therefore, I consider these forms as examples of individual variation within the same species.
