Is this a Closterus?

Thanks,

Larry B.

In spite of a narrow inter-ocular space I don't think about a Closterini. Most Closterini have the third and fourth antenal joints of the same lenght.
What is the size of this beetle ? is there a spine on the posterior angle of the pronotum ?.

Thanks Claude, unfortunately this image was sent to me by a colleague, who takes images but leaves the beetles in the field. The original image is a bit more clear, but still does not show a spine on the pronotum.

Sorry Larry, but from this picture and without complementary precision, it's difficult to find a right way for determination...
For me it's not a Closterus, but without spines on pronotum and legs unarmed, maybe genus Parelaptus or Nesopriona castanea (I don't know this species..)

Oui Thierry, c'est une bonne idée, il pourrait appartenir à M. mutica male mais pour être sur il faudrait une meilleure vue dorsale car je ne vois pas bien les côtes elytrale.. mais reste très probable

c'est un angle inhabituel, et les photos sont souvent déformantes mais je pencherais pour Megopis quand même. On devine les cotes sous forme d'ombre de relief. Le truc qui m'a fait tiquer c'est les antennomères pointus vers l'arrière mais j'ai vérifié sur les miens, c'est possible selon l'angle de la photo.

Voici un Megopis mutica de Mayotte pour comparaison.
Il y a plusieurs Megopis dans les Comores et l'ile Maurice mais, au vu de la photo, mutica reste le plus probable.
Par prudence nous laisserons le titre sous Megopis sp.
