Male Beetle

A bizarre cylindrical bark beetle from mid-Cretaceous Burmese amber is described as Stegastochlidus saraemcheana, a new genus and species in the subfamily Colydiinae of the family Zopheridae. The male beetle is characterized by elongate protuberances covering its entire dorsal surface, a tarsal formula of 4-4-4 and ten-segmented antennae with the terminal segment expanded into a small club. The fossil is considered to have been a possible predator that lived among moss, lichens and fungi either attached to trees trunks or on the forest floor. A close association with fungi is indicated by strands of conidia attached to the cuticle of the beetle.

A new genus and species of the extinct family Weitschatidae, Criniverticillus longicumulus gen. et sp. nov. (Hemiptera: Coccomorpha), is described and illustrated from mid-Cretaceous Burmese amber. The new species is based on a fossil specimen with complete body, wings and antennae. The family diagnosis is updated to include similarities between Criniverticillus, Pseudoweitschatus and Weitschatus. An identification key to species of Weitschatidae is provided.

A new fossil stonefly genus and species of the family Perlidae, Pinguisoperla yangzhouensis gen. et sp. nov., is proposed as the second known genus from mid-Cretaceous Burmese amber. The new genus is characterized by its dark coloration and the basally enlarged and curved cerci. Morphological characters of the new genus and species are described, illustrated, and compared with related taxa.

With over 4,600 species distributed worldwide, the net-winged beetles belong among the most speciose elateroid lineages. Despite this, beetles of the family Lycidae are rare in the fossil record. A new genus and species of Lycidae, Cretolycus praecursor gen. et sp. nov., is herein described based on a single specimen preserved in mid-Cretaceous Burmese amber. Cretolycus praecursor represents the second known lycid from the Mesozoic. A new tribe, Cretolycini trib. nov., is erected for the species, characterised by 11-segmented filiform antennae, 3-segmented labial palpi with an enlarged apical palpomere, and elytra without costae. A catalogue of fossil net-winged beetles is appended.

A new genus and species of apsilocephalid flies, Cascomixticus tubuliferous gen. et sp. nov. (Diptera: Asiloidea: Apsilocephalidae) is described from Burmese amber. Assignment to the Apsilocephalidae is based on the wing venation that is very similar to extant members of the family. The present fossil differs from known genera of this family by a long labellum bearing tactochemical papillae, a long tubular hypopharynx and a pointed labrum as well as the structure of the scape and pedicel. The long, tubular hypopharynx may have been used to obtain nectar from angiosperm flowers, however the function of the sharp-tipped labrum is unknown.

A new genus and species of the family Dinglidae Szwedo & Drohojowska , 2020 (Hemiptera: Sternorrhyncha), Alloeopterus anomeotarsus, is described from mid-Cretaceous Burmese amber. The new genus is characterized by a simplified forewing venation with thick veins of R and M+Cu emerging separately from the wing base, a diffuse pterostigma close to termination of RA vein, reduced vein A1, veins M and Cu unbranched, a reduced clavus, a small hindwing with a costal margin and terminal R vein weakened in apical portion; a long first flagellomere, approximately 1.5 times as long as the second flagellomere and rhinaria with sensory pits on the apex of the pedicel and flagellomeres 5 and 6. The fossil increases our knowledge of the morphological variation that occurred during the evolution of Cretaceous Sternorrhynchia.

ABSTRACTMicromalthidae is a small relictual family of archostematan beetles that is well known for its unusual asexual reproductive system characterised by parthenogenetic, viviparous, larviform females and sterile adults. Here we describe the first micromalthid beetle from mid-Cretaceous Burmese amber (ca.100Ma). Protomalthus burmaticus gen. et sp. nov. differs from all presently known micromalthid beetles by the presence of distinct frontoclypeal, labroclypeal, and medicranial sutures. The finding represents the first Mesozoic record of an adult micromalthid beetle and confirms a Gondwanan distribution of the family during the Cretaceous. A list of micromalthid beetles is provided, together with a key to extant and fossil species.

AbstractMicroberotha macculloughigen. nov. and sp. nov. from Early Eocene Okanagan Highlands amber of Hat Creek, British Columbia, Canada, is described. This new genus and species represents one of the smallest members of the family Berothidae and the first occurrence of the family in the New World Tertiary. The systematic position of the genus Microberotha within the family is rather unclear, but the structure of the male genitalia indicates a close association with the subfamily Cyrenoberothinae. Stratigraphy and palaeoenvironment of the Hat Creek locality are briefly discussed.

Phylogenetic Status

A new genus and species, Latidorsum carinbifarium Wang, Tang & Yao gen. et sp. nov., is assigned to Phatnomatini (Tinginae), which is described from the mid-Cretaceous Burmese amber. A parsimonious analysis based on 50 morphological characters with 26 terminals clarifies the phylogenetic status of the new fossils and examined relationships among the presently analysed genera of the family Tingidae. The resulting cladogram supporting Tingidae are reconfirmed as monophyletic and divided into four main clades, with relationships as follows: (Vianaidinae + ((Burmacader multivenosus + Burmavianaida anomalocapitata) + (Sinaldocader rasnitsyni + (Gyaclavator kohlsi + Tinginae + Cantacaderinae)))). Anterior length of bucculae distinctly projecting in front of head, sometimes in contact is not a synapomorphic character for Cantacaderinae, which evolves in parallel in Tinginae and Cantacaderinae.

Definition Of

AbstractThe definition of the family Evaniidae is revised and Cretevaniidae are synonymised with Evaniidae based on evidence derived from recently described Mesozoic taxa and a new genus and species, Lebanevania azari, described here from Lebanese amber. A fore leg with a long trochanter and a 12-segmented antenna are autapomorphies of the new genus. A large, high and wide head and a high and short mesosoma are derived characters shared with other Evaniidae. The new genus also has complete fore wing venation and lacks a tubular petiole, which are ground plan features of the Evanioidea. A cladistic analysis of fossil and extant members of the superfamily Evanioidea and notes on fossil taxa are presented.

A fragmentary specimen of pterosaur originally assigned to the genus Pterodaustro Bonaparte, 1970 is reassessed. The presence of a sagittal dorsal cranial crest on a fragment of nasopreorbital arcade with linear vertical trabeculae and the occurrence of alveolar protuberances on the os dentale indicate the new specimen has similarities with crested pterodactyloid pterosaurs of the family Ctenochasmatidae, and with members of the Dsungaripteridae. The presence of alveolar protuberances allows us to assign the specimen to the Dsungaripteridae. It forms the basis of a new genus and species, Domeykodactylus ceciliae.
