I am afraid it is the second option...  |

In such cases, there should be more or less firm distributional borders. So, is there something like that?
Otherwise, it is impossible to distinguish particular (ie. small) specimens. |

Maybe... but it is the same concerning sibling species.
In some cases males are well different (e.G. Dynastinae, Lucanidae), in some other ones females are well different (Vesperus). In this case, it seems to me that large decempunctata males have really a notably enlarged pronotum with respect to other species.
However, it is necessary to compare long series and specimens having the same size... a thing the author (Takakuwa) really did.
Other thing is identifying specimens through pictures... not always easy. |

Sorry, but it seems to me that all these characters are rather arbitrary... |

Après la clé de Pierre et les tableaux de Robert, je dirais plus pachycornis. |
