I have seen many D. agyleus from Colombia.
How does it compare with the image on Larry's website?

Agyleus is the closest match I can see, indeed. In all cases there are not so many possibilities.
I have inserted a picture of a specimen from Ecuador on Biolib, very similar, both have a straight pronotal apex with spines being projected strictly sidewards.
On the Otanche specimen the elytral surface is less brilliant, more silky, and the basal spines of the pronotum strong, finger-like shaped and missing sharp points. Unfortunately such details can not be seen on the single male of Larry's website.

Bonjour Pierre, j'ai un ex. de D. agyleus de Colombie (Cali) similaire au tien.
Avec un pronotum latéralement "tridenté" et un apex elytral échancré avec 2 épines, je ne vois pas trop d'autres possibilités à part D. drumonti.

Drumonti, ce n'est pas plutôt une espèce d'Amérique centrale?

Effectivement Mexique, ce qui ne laisse plus beaucoup de choix !
Quant à la configuration des épines du pronotum, il ne faut pas chercher un "standard absolu" car, à part le nombre et l'implantation, il peut être parfois observé des variations de taille et d'orientation.

Oui, Claude, tout à fait d'accord.
Je pense qu'on peut conclure sans trop de risque pour D. agyleus.
