I try to understand the systematic position of the tribes Compsocerini Thomson, 1864, and Unxiini Napp, 2007. Biolib does not separate them, other sources accept two distinct tribes.

In addition to this, does someone know any good sources or papers helping to identify the genera of these tribes? As a fact, some of them are very close especially those with hairy antenna.

Pierre,

Je pense que tu as le papier de Napp dans lequel, elle explique le caractère principal qui nécessite la création de cette nouvelle tribu:

"Unxiini, a new tribe of Cerambycinae (Coleoptera, Cerambycidae). Unxiini trib. nov. is proposed to include the
following genera up to now in Compsocerini Thomson, 1864: Chariergus White, 1855, Chenoderus Fairmaire & Germain,
1859, Unxia Thomson, 1860, Ethemon Thomson, 1864, Paromoeocerus Gounelle, 1910, Rierguscha Viana, 1970,
Parunxia Napp, 1977 and Allopeba Napp & Reynaud, 1999, whose females present a brush on the seventh abdominal tergite
used as oviposition strategy. In Cerambycidae, this kind of brush is exclusive to Unxiini.

Oui, ça, je l'ai lu. Je me demandais juste si ça suffit pour créer une nouvelle tribu. Ce genre de "brush on the 7th abdominal tergite" peut être trouvé aussi chez certains Trachyderini, (Tragidion par exemple), et également interprété comme étant un dévelopement spécifique dans le contexte de la ponte. Apparemment je ne suis pas le seul puisque les Unxiini semblent être une spécialité "américaine", peu utilisée par ici. Biolib par exemple ne parle que de Compsocerini Thomson, 1864. Les Unxiini figurent dans la liste des synonymes...
