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

Analysing the history of the derelomine flower weevil–Carludovica association (Coleoptera: Curculionidae; Cyclanthaceae)

The evolutionary history of the interaction among species of derelomine flower weevils (Coleoptera: Curculionidae: Derelomini) and the Panama-hat palm Carludovica (Cyclanthaceae) is analysed with emphasis on the congruence of (1) topologies and (2) character state transformations in each of the Neotropical clades. For this purpose cladistic analyses are complemented with host plant records, nat...

Systematics of Cyclanthura gen. n., a new genus of Derelomini (Coleoptera: Curculionidae)

The present paper supplements recent contributions to the systematics of derelomine flower weevils from the Neotropics (Franz 2001, Franz & O’Brien 2001a, 2001b). Under the current conception, Derelomini (Coleoptera: Curculionidae: Curculioninae sensu Alonso-Zarazaga & Lyal 1999) comprise 220 species and 39 genera, the majority of which are associated with the inflorescences of Arecaceae. Some ...

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...

Taxonomic use of endophallus in weevils of the genus sitona (coleoptera : curculionidae)

Re-description and first host and biology records of Entedon magnificus (Girault & Dodd) (Hymenoptera, Eulophidae), a natural enemy of Gonipterus weevils (Coleoptera, Curculionidae), a pest of Eucalyptus trees.

Entedon magnificus (Girault & Dodd) (Hymenoptera: Eulophidae, Entedoninae) is recorded as a gregarious larval endoparasitoid of Gonipterus weevils (Coleoptera: Curculionidae), significant pests of Eucalyptus trees. Entedon magnificus is re-described and illustrated based on females and males from Australia and Tasmania.
