Belongs within: Curculioninae.Contains: Lechriopini, Zygopini, Peridinetus, Ambates, Tonesiina, Nertinina, Torcina, Coelonertina, Diorymerina, Madarina, Lydamis, Eurhinina, Madopterina, Pseudobaris, Heterosternus, Baris, Solenosternus, Anopsilus. The Conoderinae are a diverse group of weevils united by the presence of a strongly curved submarginal fold on the ventrolateral surface of the elytra (Davis 2009). The monophyly of this group is uncertain… Continue reading Conoderinae


Belongs within: Conoderinae. The Madarina are baridine weevils with uninterrupted surfaces between prosternum, meso- and metaventrite, and an oblique, dorsally visible pygidium (Legalov 2018). They are usually elliptical or rhomboidal in overall shape, and often brightly coloured. Members of the genus Microstrates are found in palm flowers. Leptoschoinus and related genera have historically been separated… Continue reading Madarina


Belongs within: Conoderinae.Contains: Stegotes (Stegotes). The Diorymerina are a diverse group of baridine weevils with a concealed pygidium, and interruptions between the surfaces of the prosternum and meso- and metaventrites. The rostrum is diverse in form but never much longer than head and pronotum combined, and the prosternum either lacks a rostral channel or has… Continue reading Diorymerina


Belongs within: Conoderinae. The Eurhinina are a group of weevils characterised by a brilliant metallic coloration in the adults. Larvae of the genus Eurhinus create galls in the stems of Vitaceae. The pygidium is exposed in the genera Eurhinus, Barycerus and Barycerellus but covered by the elytra in Eurhinopsella triangularis and Pseudeurhinus violaceocoeruleus (Hustache 1949).… Continue reading Eurhinina


Belongs within: Conoderinae. The Tonesiina are a pantropical group of weevils, distinguished by their non-canaliculate and usually very wide prosternum. The species Myctides imberbis has been introduced into Florida in association with the rose apple Syzygium jambos (Anderson 2002). Characters (from Lacordaire 1866, as “Lytériides”): Prothorax with low median lobe at base; prosternum not canaliculate,… Continue reading Tonesiina


Belongs within: Conoderinae. Ambates is a genus of weevils found in the Amazon region. Characters (from Casey 1922): Beak arcuate, cylindric, antennae inserted at about middle of beak; anterior coxae contiguous; tibiae pluricostulate; claws arcuate, free; elytra not laterally carinulate, ornamentation circumambient. <==Ambates [=Ambatis (l. c.)]K83 |–A. benoisti Hustache 1949H49 |–A. bisignatusH49 |–A. boliviensis Hustache… Continue reading Ambates

Belongs within: Conoderinae. Lydamis is a genus of weevils found in Central and South America, characterised by the possession of relatively long and slender tarsal claws (Casey 1922). Characters (from Casey 1922): Body rhomboidal, generally densely clothed with variegated scales; beak evenly arcuate, cylindric and strongly sculptured; antennae medial, first two segments of funicle rather… Continue reading Lydamis


Belongs within: Conoderinae. The Madopterina are a group of weevils found in the Neotropics, distinguished by having the body particularly elongate and parallel-sided, and the prosternum posteriorly truncate or at least never with a distinct posterior lobe (Casey 1922). The tarsi are often greatly dilated. <==Madopterina |–Centrinopsis Roelofs 1875D09 | `–C. nitensM62 |–LipancylusD09 | |–L.… Continue reading Madopterina


Belongs within: Conoderinae. The Coelonertina are a group of weevils with an elongate and parallel-sided body form and coarse sculpture. They have a relatively short beak compared to other baridine weevils. Characters (from Casey 1922, as Coelonertini): Body form elongate and parallel or rigidly cylindrical, sculpture very coarse and close, vestiture partially squamiform, abdomen very… Continue reading Coelonertina
