Coelosternus

***Coelosternus*** er en slekt av snutebiller (Curculionidae) som lever på busker og trær. 

## Utseende
Små (gjerne 2 – 6 mm), avlange, høyt hvelvede, brunlige snutebiller. Kroppen er vanligvis helt dekket av skjell, noen av dem gjerne oppstående og hårlignende. **Hodet** er temmelig lite, fasettøynene er forholdsvis store og flate. Snuten er middels lang og tynn og holdes vanligvis bakoverbøyd slik at den ikke er synlig ovenfra. Den kan foldes inn i en fure mellom framhoftene som ender i en kopplignende grop på mellombrystet (*mesosternum*). Antennene er festet rundt midten av snuten. **Brystskjoldet** (pronotum) er bredere enn langt, men tydelig smalere enn dekkvingene. Sidene er avrundede. Det har ofte markerte knøler på sidene. **Dekkvingene** er ovale hos de fleste, men parallellsidige hos noen av de større artene. De har mer eller mindre markerte skuldre og ofte rekker av oppstående skjell. **Beina** er kraftige og forholdsvis lange, lårene er vanligvis utannede, men kan ha en tann på undersiden. Leggene (*tibiae*) ender i en krok (*uncus*). Føttene er nokså korte og kan foldes tilbake mot leggen. 

## Levevis
Tresnutebillene lever på ulike slags busker og trær, der de voksne billene gjerne gnager på bladene. De er sjelden spesielt tallrike og er ikke regnet som skadedyr.
## Utbredelse
Slekten er hovedsakelig neotropisk.
