WEEVILS OF THE LARINUS GENERA OF ZAPORIZ`KA OBLAST (COLEOPTERA, CURCULIONIDAE)

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

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...

Larinus berti sp. n. (Coleoptera, Curculionidae, Lixinae) from North Africa

A new species, Larinus berti sp. n. is described from Morocco and assigned to subgenus Cryphopus Petri, 1907 (Curculionidae: Lixinae; Lixini). Diagnostic characters of the new species are large size, elongate-ovate body, bisulcate sub-quadrangular rostrum, triangularly raised dorsum of rostrum, flat subgena and submentum, Y-shaped apodeme of sternite VIII of female and thin nodulus of spermatheca.

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...

Description of the immature stages of Larinus vulpes and notes on its biology (Coleoptera, Curculionidae, Lixinae)

Mature larva and pupa of Larinus vulpes (Olivier, 1807) (Curculionidae: Lixinae: Lixini) are morphologically described for the first time and compared with known larvae and pupae of other Larinus species. Very high counts of larval body setae (pronotum with more than 25 setae and postdorsum on meso- and metathorax and also on abdominal segments I-VII with more than 12 setae) are characteristic ...
