Bruchus

Belongs within: Bruchidae. Bruchus is a genus of bean weevils with a large tooth on the lateral margin of the pronotum, and a prominent tooth or angulation on the metafemur (Kingsolver 2002). Bruchus pisorum is a cosmopolitan pest on growing peas and beans (Lawrence & Britton 1991). Characters (from Kingsolver 2002): Pronotum convex, lateral pronotal… Continue reading Bruchus

Sagrinae

Belongs within: Chrysomelidae. The Sagrinae are a group of leaf beetles characterised by enlarged hind femora bearing teeth or spines. They are most diverse in Australia with the genus Sagra also found in Africa and Asia (Lawrence & Britton 1991). Characters (from Lawrence & Britton 1991): Length more than 8 mm; head somewhat rostrate, with genae and… Continue reading Sagrinae

Cryptocephalini

Belongs within: Chrysomelidae.Contains: Cryptocephalus (Burlinius). The Cryptocephalini are a group of leaf beetles whose larvae feed on dead leaves accumulated on the ground and protect themselves within a case composed of faeces and debris (Lawrence & Britton 1991). The genus Cryptocephalus is one of the largest genera recognised in the animal kingdom, with close to… Continue reading Cryptocephalini

Hispinae

Belongs within: Chrysomelidae.Contains: Hispa, Physonota. The Hispinae are a group of leaf beetles with an opisthognathous head and tetramerous tarsi. Members of the tribe Chalepini are narrow-bodied with a rough dorsum bearing coarse, deeply impressed punctation. The Mesomphaliini are broad beetles bearing a broad basal tooth on each of the tarsal claws (Riley et al.… Continue reading Hispinae

Cerambycidae

Belongs within: Phytophaga.Contains: Stenoderinae, Dorcadioninae, Hypselominae, Cirrhicera, Spondylidinae, Lepturinae, Cerambycinae, Parandrinae, Prioninae, Lamiinae. The Cerambycidae include the longicorn beetles, distinguished (as their name suggests) by the notably long antennae of many species which may be longer than the remainder of the insect. Larvae of longicorns are generally internal feeders on plants. Some species are significant… Continue reading Cerambycidae

Chrysomelini

Belongs within: Chrysomelidae.Contains: Chalcolampra, Paropsis, Gonioctena, Chrysolina, Chrysomela, Plagiodera. The Chrysomelini are a cosmopolitan group of leaf beetles including the majority of species in the subfamily Chrysomelinae, characterised by genitalia with a V-shaped tegmen. Subgroups of the Chrysomelini include the primarily Australasian Paropsina which generally have toothed claws and the epipleura completely obscured in lateral view by the… Continue reading Chrysomelini

Anthribidae

Belongs within: Phytophaga.Contains: Araecerini, Trigonorhinus, Anthribus. The Anthribidae are a group of weevils with a flattened rostrum retaining a visible labrum, and non-elbowed antennae (Britton 1970). Larvae mostly feed on dead wood, galls and fungi, except those of the Urodontinae that feed on the soft stems and seeds of monocotyledons. Subfamilies Choraginae and Anthribinae bear… Continue reading Anthribidae

Nemonychidae

Belongs within: Phytophaga. The Nemonychidae, pine flower weevils, are a group of weevils with larvae feeding on pollen of conifers. They have a primarily bipolar distribution with few species known from tropical regions (Anderson 2002). Adults are distinguished from other weevils by the combination of a free labrum, visible at the level of the clypeus,… Continue reading Nemonychidae

Curculionidae

Belongs within: Phytophaga.Contains: Alcidides, Acicneminae, Brachycerini, Tanysphyrini, Platypodinae, Dryophthorinae, Bagoinae, Erirhinina, Sitonini, Hyperinae, Cyclominae, Curculioninae. The Curculionidae are the largest family of weevils, distinguished by geniculate (elbowed) antennae with an elongate scape. Members of the family typically possess an elongate rostrum though this is relatively short in some subfamilies such as the Entiminae and absent… Continue reading Curculionidae
