Abstract
Three Graphium species belonging to two species groups of the subgenus Pazala, the alebion and tamerlanus groups,were examined in molecular and morphological studies, and their female genitalia are reported for the first time. Theirrelationship with other species groups within the subgenus is assessed and their divergence times are estimated. We findthat G. (P.) alebion is the first lineage to diverge within Pazala in the early Miocene (20 Ma) and that G. (P.) tamerlanusand G. (P.) parus are sister species and diverged from each other in the late Miocene (7 Ma). A revision of the fourrecognised taxa belonging to three species is presented, and historical misidentification of these taxa and their geographicranges are explained.
