Distribution

The Belidae today have an essentially Gondwanan distribution, occurring only in the Australia–New Guinea–New Zealand region up to Southeast Asia, South and Central America (barely reaching North America), some Pacific islands (notably the Hawaiian Islands) and a few places in Africa. Many lineages of belids are notable for their highly relictual distribution; for example the Aglycyderini are found in two areas on opposite sides of the Earth, with no such beetles known from anywhere in between.[1]

Belids were more widespread during the Late Jurassic to Early Cretaceous, about 161 to 100 million years ago, when they were found at least in Central Asia, Spain and Brazil.[2] Paleogene species belonging to still-living tribes are known from Europe and North America.[1]

Description

Rhinotia haemoptera resembles a fire-coloured beetle (Pyrochroidae) in colour.

Members of the subfamily

Pyrochroidae.[1]

The adults are distinguished from other ancient weevil lineages by some characteristic traits: The fore

pronotum is constricted at the tip (not in Oxycorynus, Parallocorynus and Rhopalotria).[1]

The endocarina is V-shaped. In most, the antennae have a retractable membrane at the base (not in

caeca distributed all over at random (in two clean bundles in Aglycyderini and Metrioxenini).[1]

Ecology

The Atala butterfly (Eumaeus atala) can only survive because the belid Rhopalotria slossoni pollinates its foodplant.

Adults usually eat

Coontie (Zamia pumila); indirectly, the Atala butterfly (Eumaeus atala
) also depends on this beetle.

The original host plants of belids were probably

palms. The Pacific genus Proterhinus has undergone a vigorous adaptive radiation on the Hawaiian Islands and evolved to utilize a wide range of the limited diversity of plants found there.[1]

Systematics

The

subfamilies have each, at various times, been considered as separate families, but they are grouped together in most recent classifications. There are three main living lineages, variously considered three or, as here, two subfamilies, with the tribe Aglycyderini sometimes considered a distinct subfamily. Other classifications treat the Oxycoryninae as distinct family Oxycorynidae. A prehistoric subfamily only known from Mesozoic fossils are the Eobelinae.[1][2]
