本文首次报道了隐喙象甲亚科的系统发育。推断的模式和时间象甲家庭关系一般与以前的研究一致，但我们的数据是第一个建议高度支持的姐妹群之间的关系Attelabidae和Belidae。我们的地理推断表明Cryptorhynchinae s.s.起源于白垩纪晚期（C。86 Ma）在南美洲。在Acalles群和Cryptorhynchus群中，在晚白垩世和早第三纪发生了几次独立的经新北向古北西部的扩散事件。第二条经由南极洲的南线可能促进了澳大利亚在白垩纪晚期的殖民化（c。82 Ma），其中一个不同的印度-澳大利亚分支可能出现c。73 Ma.早始新世（C。50-55 Ma），几个分支独立地从澳大利亚分散到原新几内亚，即部落Arachnopodini s.l.，Rhynchodes组和Trigonopterus属。新西兰最早在古新世晚期被殖民。60 Ma）。分歧时间估计和地理重建表明，新几内亚的殖民地比该地区目前的地质重建所预期的要古老。
The first dated phylogeny of the weevil subfamily Cryptorhynchinae is presented within a framework of Curculionoidea. The inferred pattern and timing of weevil family relationships are generally congruent with previous studies, but our data are the first to suggest a highly supported sister‐group relationship between Attelabidae and Belidae. Our biogeographical inferences suggest that Cryptorhynchinae s.s. originated in the Late Cretaceous (c. 86 Ma) in South America. Within the ‘Acalles group’ and the ‘Cryptorhynchus group’, several independent dispersal events to the Western Palaearctic via the Nearctic occurred in the Late Cretaceous and Early Paleogene. A second southern route via Antarctica may have facilitated the colonization of Australia in the Late Cretaceous (c. 82 Ma), where a diverse Indo‐Australian clade probably emerged c. 73 Ma. In the Early Eocene (c. 50–55 Ma), several clades independently dispersed from Australia to proto‐New Guinea, i.e. the tribe Arachnopodini s.l., the ‘Rhynchodes group’ and the genus Trigonopterus. New Zealand was first colonized in the Late Palaeocene (c. 60 Ma). Divergence time estimations and biogeographical reconstructions indicate that the colonization of New Guinea is older than expected from current geological reconstructions of the region.
