Lygistorrhinidae (Diptera: Bibionomorpha: Sciaroidea) in early Eocene Cambay amber

  title={Lygistorrhinidae (Diptera: Bibionomorpha: Sciaroidea) in early Eocene Cambay amber},
  author={Frauke Stebner and Hukam Singh and Jes Rust and David A. Grimaldi},
One new genus and three new species of Lygistorrhinidae in early Eocene Cambay amber from India are described, which significantly increases our knowledge about this group in the Eocene. Lygistorrhina indica n. sp. is the oldest fossil known from this extant genus. Indorrhina sahnii n. gen. et sp. shows morphological similarities to each of the two extant genera Lygistorrhina and Asiorrhina. Palaeognoriste orientale is the third species known from a group that has only been recorded from Eocene… 

Another Laurasian connection in the Early Eocene of India: Myrmecarchaea spiders (Araneae, Archaeidae)

The first fossil Archaeidae in Cambay amber from India, of Eocene age, is documented and placed as Myrmecarchaea based on the presence of elongated legs, a slightly elongated pedicel with lateral spurs, and a diastema between coxae III and IV that is similar to M.antecessor from Oise amber.

Diversity of Lygistorrhina (Probolaeus) Williston, 1896 (Diptera: Keroplatidae, Lygistorrhininae) of Mitaraka (French Guiana), with descriptions of three new species

Three new species of Lygistorrhina (Probolaeus) Williston, 1896 are described, which were collected mainly by Malaise and SLAM traps in Mitaraka, southwestern French Guiana, during the “The authors' Planet Revisited” expedition in 2015.

A peculiar leg structure in the first non-biting midge described from Cambay amber, India (Diptera: Chironomidae)

The combination of the head and genital apparatus characters supports the hypothesis that Gujaratomyia and Cladotanytarsus are members of a common group within the subtribe TanyTarsina.

Transitional morphology and Afrotropical affinity of a bythinoplectine rove beetle from the early Eocene of India (Coleoptera: Staphylinidae: Pselaphinae)

The fossil taxon signifies a biotic link between early Eocene India and continental Africa, and marks the Cenozoic emergence of a tropical leaf litter arthropod fauna approaching that of contemporary, ant-dominated rainforests.

Nueva especie y nuevos registros de Lygistorrhina Skuse de México (Diptera: Lygistorrhinidae)

The male is distinguished mainly from other congeneric species by the presence of a pair of preapical setae on the mediotergite, pale-yellow fore coxa, with brown pigmentation medially, and “U-shaped” tegmen.

  • 2019
Three new genera and species of flea beetles (Chrysomelidae: Alticini) are described from the lowermost Eocene Cambay amber of India, with similarities to Afrotropical elements interpreted to be a result of Neogene migrations from Laurasia to Africa.

A New Species of Eumanota Edwards (Diptera: Mycetophilidae: Manotine) from Colombia: Evidence for a Pseudogondwanan Pattern

The biogeographical significance of Eumanota in the Neotropical region is discussed, interpreted here as a concurrent incidence of a circumtropical pattern and Gondwanan distributions, in other words, a particular pattern of biogeographic pseudocongruence, referred to here as “pseudogondwana pattern.”

Comparison of Biting Midges of the Early Eocene Cambay Amber (India) and Late Eocene European Ambers Supports the Independent Origin of European Ambers

Strong differences in the proportion of tropical components among Ceratopogoninae from different European ambers are in agreement with data on Cambay amber and so are indicative of origin of the Europe ambers under different climatic and hence geographic environments.

The Fossil Record of Long-Proboscid Nectarivorous Insects

The paper overviews the fossil record of insects with long mouthparts and rostra adapted to feeding on floral nectar and pollination drops of extinct gymnosperms. The presence of suctorial mouthparts

The vision of David Grimaldi

This issue has been compiled in recognition of David A. Grimaldi’s remarkable ongoing impact on the fields of paleontology, entomology, and evolutionary biology.



The bees of Early Eocene Cambay amber (Hymenoptera: Apidae)

The fauna of bees known from Early Eocene (Ypresian) Cambay amber are reviewed and two new species of the genus Melikerte Engel are documented, one representing a new subgenus, Paramelikertes Engel & Ortega-Blanco, as is a third, fragmentary melikertine of uncertain identity.

Asiorrhina, a new Oriental genus of Lygistorrhinidae (Diptera: Sciaroidea) and its phylogenetic position

All recent taxa of Lygistorrhinidae form a monophyletic group with the fossil genus Palaeognoriste Meunier as the sister group.

Parisognoriste, a new genus of Lygistorrhinidae (Diptera: Sciaroidea) from the Oise amber with redescription of Palaeognoriste Meunier

A new genus and a new species of Lygistorrhinidae, Parisognoriste eocenica is described from the Eocene Oise amber of the Paris Basin, demonstrating a new approach in cybertaxonomy including automatic generation of manuscript within Virtual Research Environment (Scratchpads), semantic enhancements, and parallel release of the publication on paper and on-line accompanied with registration of new taxa with ZooBank.

This is the first fossil record of this rare family in Dominican amber and the first record for Hispaniola in general as the family is currently unknown from the extant fauna.

The extinct genus Pareuthychaeta in Eocene ambers (Diptera: Schizophora: Ephydroidea)

Comments are provided on the relationships of Pareuthychaeta to Recent genera of Diastatidae sensu lato (including Campichoetinae), and implications of this extinct genus are discussed regarding biogeography and the early Paleogene Schizophora radiations.

Notes on the genus Lygistorrhina Skuse with the description of the first Nearctic species

A new species of Lygistorrhina Skuse, sanctaecatharinae, is described from southeastern United States; the genus is redescribed; its placement within the Mycetophiloidea is discussed; and it is considered to represent a separate family.

New taxa of the Lygistorrhinidae (Diptera: Sciaroidea) and their implications for a phylogenetic analysis of the family

The phylogeneticrelationships among the taxa of Lygistorrhinidae were studied by parsimony analysis using 43 morphological characters from the adults of 25 ingroup and one outgroup species and the solution obtained suggests unambiguously the following phylogeny.

Biting Midges (Diptera: Ceratopogonidae) from Cambay Amber Indicate that the Eocene Fauna of the Indian Subcontinent Was Not Isolated

Faunal links among Ceratopogonidae from Cambay amber and contemporaneous amber from Fushun, China, Eocene Baltic amber from Europe, as well as the modern Australasian and the Oriental regions imply that faunal exchange between Europe, Asia and India took place before the formation of Cambay Amber in the early Eocene.

A new species of Lygistorrhina Skuse (Diptera: Sciaroidea: Lygistorrhinidae) from South Africa

A new species of Lygistorrhina from South Africa is described and a key for Afrotropical species of the genus is provided.
