Formosan Cossonine Weevils of Bamboo (Coleoptera: Curculionidae: Cossoninae)

Towards a phylogenetic system of derelomine flower weevils (Coleoptera: Curculionidae)

A revised phylogenetic classification for derelomine flower weevils (Coleoptera: Curculionidae: Curculioninae: Derelomini Lacordaire) is proposed, based on a cladistic analysis of 115 outgroup and ingroup taxa and 155 primarily morphological characters. The single most-parsimonious cladogram (length 1⁄4 271, consistency index 1⁄4 65, retention index 1⁄4 95) indicates that several genera must be...

Pollination of Anthurium (Araceae) by derelomine flower weevils (Coleoptera: Curculionidae).

Cyclanthura flower weevils (Coleoptera: Curculionidae: Derelomini) are identified for the first time as pollinators of multiple species of Anthurium (Araceae) in Costa Rica. The weevils are present on the inflorescences in small numbers during the pistillate and staminate phase of anthesis, and consume plant tissues and pollen. The individuals of one species of Cyclanthura can visit several Ant...
