Erythrodiplax kimminsi (Chalk-marked Dragonlet)

Painfully similar to Erythrodiplax andagoya (Andagoya Dragonlet) but the markings at the root of the hindwing are larger, both the dak patch and the surrounding pale border (presumably the “chalk mark”). Some have “extensive black on middle abdominal segments”. My specimen certainly has more black than the specimen shown in the book but whether it’s extensive ..?
