Abstract
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 oldest documented ambrosia beetle that demonstrates glandular sac mycangia containing yeast-like propagules and hyphal fragments.

A new weevil, Burmorhinus georgei gen. et sp. nov. from the tribe Arthrostenini (Curculionidae: Erirhininae) is described from Cretaceous Burmese amber. The new genus is similar to the genus Thecorhinus Faust, 1887 but differs from the latter in having the body lacking wide scales, the tibiae being slightly widened at the apex, with large spurs, and weakly laminate tarsal claws. It is distinguished from the genus Arthrostenus Schoenherr, 1826 in the body lacking wide scales, the tibiae not serra...

A new weevil, Aepyceratus hyperochus gen. et sp. nov., Aepyceratinae subfam. nov., is described from mid-Cretaceous Burmese amber. The new subfamily differs from the previous Mesozoic subfamilies Brenthorrhininae, Eobelinae, Cretonemonychinae and Paleocartinae by the short lateral pronotal carina, stark convex eyes and basal antennal insertion. From the subfamilies Rhinorhynchinae and Cimberidinae, it is distinguished by the short lateral pronotal carina, exodontous mandibles and basal antennal ...

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...

The ambrosia beetle–fungus farming symbiosis is more heterogeneous than previously thought. There is not one but many ambrosia symbioses. Beetle-fungus specificity is clade dependent and ranges from strict to promiscuous. Each new origin has evolved a new mycangium. The most common relationship with host trees is colonization of freshly dead tissues, but there are also parasites of living trees, vectors of pathogenic fungi, and beetles living in rotten trees with a wood-decay symbiont. Most of t...

A new tribe, Mekorhamphini trib. n., two new genera Mekorhamphus gen. n. and Habropezus gen. n. and two new species ( M . gyralommus sp. n. and H . plaisiommus sp. n.) are described from Burmese amber. The new tribe resembles the tribe Mesophyletini but differs from the latter by possessing contiguous procoxal cavities and very wide elytra with regular striae. From the tribe Anchineini, it differs by the contiguous procoxal cavities, precoxal portion of the prosternum elongated, and swollen troc...

All known extinct species of Mesozoic and Cenozoic weevils are listed. Ten species of Obrienioidea and 895 Curculionoidea species are recognized, including 88 Nemonychidae, 43 Anthribidae, 44 Ithyceridae, 65 Scolytidae, 12 Belidae, 67 Brentidae, 508 Curcuionidae, 45 Rhynchitidae, six Attelabidae, and 16 Platypodidae. The Triassic beds have yielded six fossil species; Jurassic, 64; Jurassic–Cretaceous boundary, 2; Cretaceous, 105; Paleogene, 510; Neogene, 190; and Pleistocene–Holocene, 22 (5 are ...

Abstract Platypodinae is a peculiar weevil subfamily of species that cultivate fungi in tunnels excavated in dead wood. Their geographical distribution is generally restricted, with genera confined to a single continent or large island, which provides a useful system for biogeographical research. This study establishes the first detailed molecular phylogeny of the group, with the aim of testing hypotheses on classification, diversification, and biogeography. A phylogeny was reconstructed based o...

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...

Two new species are described from Mexican amber (15–20 Ma): Cenocephalus tenuis Peris and Solorzano Kraemer sp. nov. and Tesserocerus simojovelensis Peris and Solorzano Kraemer sp. nov. Cenocephalus, originally described as living in Central and South America and then as fossils from Early to Middle Miocene amber, is noted as morphologically indistinguishable from Mitosoma, and originally described as endemic from Madagascar. Thus, we consider that a close taxonomic relationship exists, even if...

The present work reveals plant and animal associates of 16 families and subfamilies of fossil beetles that have been preserved in amber from Mexico, the Dominican Republic, and Myanmar. The associates include mites, pseudoscorpions, spiders, insect parasites and predators, fungi, angiosperm parts, vertebrates, and nematodes. The presence of these fossil associates can be attributed to the rapid preservation of organisms in resin, thus maintaining natural associations almost “in situ”. Examples o...

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...
