There is no reported Stenoderus from Solomon Island, so I suppose this species is undescribed ?
Guadalcanal, 13,8 mm.

Je ne connais pas du tout cette tribu, mais le genre Syllitus Heller, 1914 me semble très proche lui aussi.

Oui, tout à fait mais il y a une différence évidente entre ces 2 genres (d'après Slipinski & Escalona, 2016) :
Syllitus : yeux de forme ovale et grossièrement facettés;
Stenoderus : yeux de forme circulaire et finement facettés.
Je suis en cours de description de cette espèce, merci de la déplacer dans la section confidentielle...

This species looks very similar to Syllitus bicolor Schwarzer I collected in New Britain, and for sure belongs to Syllitus.
The shape of eyes round or oval is not clear for differentiation, but the faceting of eyes is ok; otherwise, Stenoderus is distributed in Australia only.

Also very close to Syllitus insularis Gressitt, 1959.
Be carefull while descripting a new species...

Thank you Andreas. You are almost right ! but your observation put me on the right track. This is Syllitus insularis Gressitt, 1959.
It differs from Syllitus bicolor (Schwarzer, 1924) in having a pitchy head above and very shiny head and prothorax (not very shiny in bicolor according to Gressitt, 1959).
The eyes are coarsely facetted comparatively with Stenoderus.
The tribe is Stenoderini.
Description avortée .

Merci Xavier pour ta détermination et je suis content de voir que nous sommes arrivés à la même conclusion.
Ne soit pas fâché, je ne suis pas animé de mauvais sentiments, nous avons tous deux la même passion et peut-être beaucoup d'autres points communs. Je t'invite d'ailleurs à venir me voir près de Montélimar si tu as l'occasion de prendre la N7, pour partager cette passion de vive voie.
