Curculionidae (weevils and bark beetles)

The last beetle family for me to review and identify my outstanding specimens... This is in progress and will hopefully be completed soon.

When using Duff's key to subfamilies of Curculionidae I have found couplet 26 (where Entiminae splits off) practically impossible to judge. It's worth bearing in mind the majority of Entiminae would hit an obvious dead-end at couplet 27, so when I get to couplet 26 I find it easier to check couplet 27 first and if it fails there assume it's Entiminae.

Subfamily Curculioninae

includes genera Acalyptus, Cionus, Curculio, Dorytomus, Furcipus, Orchestes and Rhamphus

Subfamily Baridinae

includes genus Limnobaris

Subfamily Ceutorhynchinae

includes genera Ceutorhynchus, Nedyus, Parethelcus, Rhinoncus and Trichosirocalus

Brachypera zoilus
