摘要：
Among D. bipectinata Duda, 1923, three subspecies, bipectinata from Southeast Asia (SEA) and Okinawa (OKN), szentivanii stat. nov. from Papua New Guinea (PNG) (Mather & Dobzhansky, 1962) and pacificiae ssp. nov. from South Pacific Ocean (SPO), are recognized. The external morphology of the reproductive organs and the numbers of teeth per row in the sex combs are different between the three subspecies. Furthermore, the sterility of hybrid males between strains from the different regions confirms the subspecies status of each population from SEA, PNG and SPO, together with different gene arrangements in the geographical populations. Although males of the strains from OKN (Okinawa), the northernmost population, show significant differences in the number of teeth of sex combs from males of SEA (Southeast Asia) strains, hybrid males between them are fertile.
