'''''Synthlibonotus''''' is a genus of broad-nosed weevils in the family Curculionidae distributed in northern South America.<ref name=":0">{{Cite book|last=Alonso-Zarazaga|first=M.

== Taxonomy == ''Synthlibonotus'' belongs in the tribe Eustylini. It was described for the first time by Carl Johan Schönherr in 1847 (p. 41).<ref name=":2">{{Cite book|last=Schönherr|first=C.J.|url=https://biodiversitylibrary.org/page/4822326|title=Mantissa secunda familiae curculionidum.

== Description == The genus ''Synthlibonotus'' was characterized by Schönherr as follows:

{{Blockquote|text=Antennae longiusculae, minus tenues; scapus oculos superans, sensim incrassatus, articulis duobus basalibus funiculi longiusculis, reliquis gradatim paullo brevioribus, omnibus obconicis; clava elongata, subovali.

Rostrum breviusculum, crassiusculum, subteres, apice paullo crassius.

Oculi rotundati, nonnihil convexi.

Elytia ovalia, basi truncata, dorso antice deplanata.|author=Schönherr|title=Mantissa secunda familiae curculionidum.|source=p. 41.}}

'''''Synthlibonotus''''' resembles some members of the genus ''Exophthalmus'' but can be distinguished by their long antennal scapes that reach beyond the anterior margin of the pronotum. The scale coverage can be relatively dense and uniform or essentially absent. There is noticeable sexual dimorphism, with females much broader than males.

== Distribution == Members of the genus ''Synthlibonotus'' can be found in Mexico, Guatemala, Colombia, and Venezuela.<ref name=":0" /><ref name=":1" />

== Species == The genus contains three described species:<ref name=":1">{{Cite journal|last=Wibmer|first=G. J.|last2=O’Brien|first2=C.
