Eobelinae
Eobelinae are an extinct beetle subfamily that throve in the late Mesozoic. They belong to the belids or "primitive weevils" of the family Belidae. The Belidae today occur only from the Australia-New Guinea-New Zealand region to Southeast Asia, some Pacific islands, South and Central America and a few locations in Africa. The Eobelidae were more widespread, occurring at least in Central Asia, Spain and Brazil during the Late Jurassic and Early Cretaceous (about ).〔Ming ''et al.''(2006)〕
==Description==
Adult Eobelidae are recognizable by their elongated and flat body and long rostrum ("snout"), the latter being longer than the head and pronotum together. Like in other belids, their antennae were straight, not elbowed as in the true weevils (Curculionidae); they insert near the rostrum's center. The "forehead" between the rostrum base and the eyes has a marked outward bulge. The tibiae of the middle and hind legs have spurs at their tips.〔
Their larvae are unknown. Presumably, like the living belids, they fed on the wood and fruits of diseased or dying plants or on deadwood, with healthy plants less important as food. Given that Araucariaceae are the host plants of many of the older extant lineages of belids, it is quite likely that Eobelinae utilized these conifers too. Indeed, the Araucariaceae flourished at the same time as the Eobelidae, whereas most other known host plants of belids are angiosperms, a group of which the first primitive members (e.g. ''Archaefructus'') lived at the same time as the Eobelidae.〔Marvaldi ''et al.''(2006)〕
