Abstract
A new genus and species of weevils (Coleoptera: Curculionidae: Anchineus dolichobothris Poinar and Brown) are described from Cretaceous Burmese amber. The new genus is characterized by: a long, narrow rostrum in the upper position, geniculate antennae with a loosely compact club, antennal scrobes extending the length of the rostrum, a lobed fifth tarsal segment, small trochanters, a well developed unguitractor plate, divaricate, toothed, tarsal claws and unequal ventrites.

A new subfamily, genus and species of weevils (Coleoptera: Curculionoidea; Eccoptarthridae: Mesophyletinae: Mesophyletis calhouni Poinar) are described from Cretaceous Burmese amber. This fossil differs from all previously described Cretaceous weevils, in having definite geniculate antennae with an elongate scape and antennal scrobes, prolonged trochanters, toothed tarsal claws, and long pedunculate lobes on the third tarsal segment. The presence of the latter characters suggests that its life s...

Amber (‘Burmite’) from the Hukawng Valley of Myanmar has been known since at least the 1st century AD. It is currently being produced from a hill known as Noije Bum, which was first documented as a source of amber in 1836. Several geologists visited the locality between 1892 and 1930. All of them believed that the host rocks to the amber are Tertiary (most said Eocene) in age, and this conclusion has been widely quoted in the literature. However, recent work indicates a Cretaceous age. Insect in...

The main goals of this study were to provide a robust phylogeny for the families of the superfamilyCurculionoidea,todiscoverrelationshipsandmajornaturalgroupswithinthefamilyCur- culionidae,andtoclarifytheevolutionoflarvalhabitsandhost-plantassociationsinweevilstoanalyze their role in weevil diversiecation. Phylogenetic relationships among the weevils (Curculionoidea) were inferred from analysis of nucleotide sequences of 18S ribosomal DNA (rDNA; »2,000 bases) and 115 morphological characters of ...

A brief account of the present state of weevil taxonomy is followed by a detailed study of certain structures used in their classification, namely the venter, abdominal tergites, sternite 8 of the male, apex of the hind tibia and deciduous mandibular processes. A key to some 50 families and subfamilies of Curculionoidea is followed by a list of family-group taxa. The following changes are made: Brachyceridae, Erirhinidae, Cryptolaryngidae and Raymondionymidae are promoted to family rank from Cur...

ABSTRACTAn ambrosia beetle described as Palaeotylus femoralis n. gen et sp. belonging to a new subfamily (Palaeotylinae n. subfam.: Coleoptera: Platypodidae) is described from Cretaceous Burmese amber. It differs from other subfamilies by the loose antennal club, 6-articled funicle, coarsely faceted eyes, tibiae with teeth at apex, bilobed meso- and meta-tarsomeres 2 and 3 and tarsomere 1 shorter than tarsomeres 2–4 combined. This is the first described Platypodidae from Burmese amber and the ol...

Only a few weevils have been described from Burmese amber, and although most have been misclassified, they show unusual and specialised characters unknown in extant weevils. In this paper, we present the results of a study of a much larger and more diverse selection of Burmese amber weevils. We prepared all amber blocks to maximise visibility of structures and examined these with high-magnification light microscopy as well as CT scanning (selected specimens). We redescribe most previously descri...

Abstract A new weevil, Oropsis marinae gen. et sp. nov., Oropsini trib. nov., is described from Lower Cretaceous Lebanese amber. The new genus is similar to the genera Libanorhinus Kuschel et Poinar, 1993 and Arra Peris, Davis et Delclos, 2014. It differs from Libanorhinus in the long abdominal ventrite 1, prosternal process distinctly extends beyond procoxal cavities and tarsomere 3 weakly bilobed, and from Arra in the arcuate pronotal sides, antennal club with fused articles, long abdominal ve...

Two new tribes in the Curculionoidea are described as the Anchineini Poinar and Legalov, n. trib. (Ithyceridae: Carinae) and Paleocryptorhynchini Poinar and Legalov, n. trib. (Curculionidae: Erirhininae). The genus Anchineus Poinar and Brown, 2009, n. placem. is transferred from the subfamily Curculioninae of the family Curculionidae to the subfamily Carinae of the family Ithyceridae. The genus Paleocryptorhynchus Poinar, 2009, n. placem. is transferred from the subfamily Cryptorhynchinae to the...

SummaryNew species of rhynchitid weevils, Rhynchitobius tanyrhinus n. sp. and R. xuthocolus n. sp. (Coleoptera: Rhynchitidae) in the tribe Auletini are described from Dominican amber. The former species is characterized by a long rostrum, narrow pronotum and elytra, rugose elytral intervals and distinct elytral striae. The latter species has a short rostrum, wide antennal club, yellow legs, non-rugose elytral intervals and weak elytral striae. The present study describes the first representative...
