Have not yet seen A. immaculifrons, which is known from Central Vietnam, nor A. panybeus, which might occur, given its distribution both to the north and to the southwest of Vietnam. But it has not been recorded yet, although it is not that difficult to recognize when seen well. Yet another Anax is A. nigrofasciatus, a common mountain species.
|Male A. parthenope julius, with extensive pale markings on brownish abdomen, reddish femora. A nice dragonfly.|
|The frons in dorsal view, with black cross bar bordered by pale blue|
|Seen from the front the frons has a clear horizontal black field. The brown spot on the postclypeus is an aberration.|
|The appendages in dorsal view. Note the very short and rounded epiproct.|
