Belongs within: Phytophaga.Contains: Nanophyinae, Eurhynchinae, Apioninae, Brentini, Eremoxenini, Microtrachelizina, Trachelizina, Cyphagogini, Stereodermini, Ithystenini, Arrhenodini. The Brentidae are a family of weevils whose larvae burrow into wood, seeds or other plant structures. Brentids are highly variable in body form, including elongate forms such as members of the subfamily Brentinae as well as the more compact Apioninae.… Continue reading Brentidae

Eremoxenini

Belongs within: Brentidae. The Eremoxenini are a group of weevils often associated with ants. Members are characterised by sexually dimorphic modifications of the head and rostrum, and tarsite 3 is more or less laterally compressed and not bilobed (Zimmerman 1994). <==EremoxeniniB14 | i. s.: CobalocephalusB14 | SymmorphocerusB14 |–Eremoxenus [Eremoxenina]B14 `–Amorphocephalina [Amorphocephalides, Amorphocephalini]Z94 |–Amorphocephala coronata (Germar… Continue reading Eremoxenini

Ithystenini

Belongs within: Brentidae. The Ithystenini are a primarily Indo-Pacific group of weevils with outlying representatives in South America and Madagascar. Members have notably long and slender antennal segments, including in the club, and each elytron bears a slender, acute, conical, spiniform, caudal process well isolated from the suture by two or three interval spaces (Zimmerman… Continue reading Ithystenini

Cyphagogini

Belongs within: Brentidae. The Cyphagogini are long-bodied weevils with the sides of the anterior part of the prothorax laterally compressed or concave, modified for reception of the femora, and/or the coxae are extended laterad in points over the trochanters and visible extending beyond the sides of the prothorax when viewed from above (Zimmerman 1994). <==Cyphagogini… Continue reading Cyphagogini

Apioninae

Belongs within: Brentidae.Contains: Aplemonini, Oxystomatini, Apion, Notapionini. The Apioninae are pear-shaped weevils whose larvae mine stems, feed on developing fruit pericarp, or develop in seeds (Anderson & Kissinger 2002). Characters (from Anderson & Kissinger 2002): Body “pear-shaped”; antenna straight, not geniculate, scape shorter than combined length of first three articles of funicle; funicle with seven… Continue reading Apioninae

Aplemonini

Belongs within: Apioninae. The Aplemonini are apionine weevils with confluent mesocoxal cavities, and all elytral striae complete, coarsely impressed and punctate, with stria 1 straight at the base and not reaching the elytra’s basal margin (Zimmerman 1994). <==AplemoniniZ94 |–AplemonusZ94 |–PrissotrichiumZ94 |–ChilapionZ94 |–CircapionZ94 |–Podapion Riley 1883Z94 | `–P. gallicola Riley 1883AK02 `–OnychapionZ94 |–O. dumonti (Peyerimhoff 1929)HF03… Continue reading Aplemonini

Apion

Belongs within: Apionini. Apion is a cosmopolitan genus of straight-snouted beetles of uncertain circumscription, essentially containing less specialised members of the Apionini. Core members of the genus in the Holarctic realm are associated with Polygonaceae (Anderson & Kissinger 2002). Members of the subgenus Perapion differ from Apion sensu stricto in their confluent mesocoxal cavities and… Continue reading Apion

Notapionini

Belongs within: Apioninae. The Notapionini are shiny black apionine weevils with confluent mesocoxal cavities and at least some elytral striae incomplete (Zimmerman 1994). Characters (from Zimmerman 1994): Shiny black with mostly smooth, shiny derm. Elytra with some or most striae poorly defined, incomplete or wanting and/or stria 1 continued basad of apex of scutellum and… Continue reading Notapionini

Eurhynchinae

Belongs within: Brentidae. The Eurhynchinae are an Australasian group of weevils with poorly known biology (Zimmerman 1994). Characters (from Zimmerman 1994): Antenna with loose club. Rostrum with narrow, shallow sulcus extending along junction between lateral and ventral surfaces of each side of rostrum from beneath anterior corner of eye to below antennal insertion. Mandibles strongly… Continue reading Eurhynchinae
