Tipulomorpha are known back to the Triassic but are very rare in the fossil record of that period. The oldest tipuloid genus, Archilimonia Krzemiński & Krzemińska, 2003, is redescribed based on the type and a new species from the Middle Triassic (early Anisian, 242–247 Ma) of the northern Vosges Mountains, NE France. Male terminalia of Triassic Tipulomorpha are described for the first time: a terminal gonostylus divided into a fleshy setose clasper and a lobe in Archilimonia grauvogeliana sp. nov. The systematic position of Archilimonia is investigated based on morphological characters of both extant and extinct taxa of Tipulomorpha and other infraorders. Our cladistic analysis is congruent with the family-level relationships recovered by the most recent phylogenetic studies of Tipulomorpha, and the position of some extinct taxa is discussed. The divided gonostylus is considered a synapomorphy of Tipuloidea except Pediciidae, so in our analyses we place Archilimonia between Pediciidae and other Tipuloidea (Limoniidae + (Tipulidae + Cylindrotomidae), with two other Triassic tipuloid genera (Mabelysia and Metarchilimonia). The family Tipulidae including the Mesozoic genus Tipunia is monophyletic, so Tipulidae has existed since the Late Jurassic. http://zoobank.org/urn:lsid:zoobank.org:pub:4C0BA500-A928-4C83-ABE1-8B42BB01A803

New species of Leptotarsus (Tipulidae s.str.) are described from the Early Cretaceous beds of Brazil (Santana Fm. Aptian/Albian, ca. 112 Mya) and Spain (La Huérguina Fm., Late Barremian, ca. 126 Mya), vis. L. grimaldii sp. nov., L. cretaceus sp. nov., L. martinsnetoi sp. nov., L. buscalioniae sp. nov., L. ibericus sp. nov. and L. contractus sp. nov. Males of three species possess extremely long antennae. The fossils are the oldest representatives of the genus Leptotarsus, and the oldest known members of the family Tipulidae.

Four new species of Chironomidae with well-developed elongate proboscises are described from a Late Jurassic site Shar Teg in SW Mongolia. These are named Creta

The new species of Axymyiidae Juraxymyia krzeminskii sp. n. and Sinaxymyia szadziewskii sp. n. from the Lower Cretaceous beds of Transbaikalia and Juraxymyia evae sp. n. from the Lower Cretaceous beds (Upper Jurassic not excluded) of Yakutia are described.

New nematoceran taxa are described based on isolated wings from the Late Jurassic Shar Teg locality (Mongolia): ?Nannotanyderus incertus sp. nov. (Tanyderidae), Crenoptychoptera liturata sp. nov. (Ptychopteridae), Chaoburmus amphilogos sp. nov., Mesocorethra cincta sp. nov. (Chaoboridae), Rasnicynomma additum gen. et sp. nov., and Palaeoperissomma ornatum sp. nov. (Perissommatidae).
