Fig. 4. Geographical distribution of the known records of Gallancyra dentata (Sugimoto, 1934), based on the reports cited in Table 1. Black circles indicate countries where G. dentata has been reported at in at least one survey, including the present report. Hollow circles indicate countries for which surveys of domestic chicken have been published, but G. dentata has not been found. In addition to the areas indicated on the map, Emerson (1956) reported G. dentata from "various islands in the Central Pacific Area", but gave no detail.
