Ganglionus, a New Genus of Derelomini (Coleoptera: Curculionidae) Associated with Carludovica (Cyclanthaceae)

چکیده
Ganglionus, gen. nov., is described for Þve species: G. mitigatus, sp. nov., from Costa Rica;G. catenatus, sp. nov., fromCosta Rica and Panama;G. undulatus, sp. nov., fromCosta Rica and Panama;G. constrictus, sp. nov., fromEcuador; andG. spatulatus, sp. nov., fromColombia.Ganglionus is placed in Derelomini and presents the following putative synapomorphies: male with (1) dorsally tumescent rostrum, (2) posteriorly setose sternum VIII, and (3) apically O-shaped tegmen. Ganglionus is associated with Carludovica Ruṍz & Pavón (Cyclanthaceae). Observations on the biology ofG. undulatus at La Selva, Costa Rica, indicate that the adults are pollinators. The females oviposit into the staminate ßowers of the host inßorescences, and the larvae complete their development in the leaf litter.Acladistic analysisÑusingNotolomusbasalisLeConte, Staminodeus vectorisFranz, and Perelleschus carludovicae (Günther) as outgroups proposes the relationships (G. mitigatus, ((G. catenatus, G. undulatus), (G. constrictus, G. spatulatus))).

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...

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...

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 ...
