The first Early Cretaceous representative of the fly family Tipulidae from the lower Barremian dysodiles of Lebanon (Diptera).

Leptotarsus reyi sp. nov., first representative of the family Tipulidae from the Lower Cretaceous of Lebanon, is characterised, described and illustrated from the Early Barremian dysodile of Jdeidet Bkassine, South Lebanon.

New stem-anisopteran dragonflies in the Jurassic of China (Odonata: Epiproctophora).

The odonatan asiopterid Turanopteron sinensis sp. nov. and the juragomphid Oxfordgomphus trescellulae gen. et sp. nov. are described on the basis of two new fossil wings from the Middle-Upper Jurassic of Henan Province in China. These taxa belong to ancient, Toarcian epiproctophoran stem groups of Anisoptera Selys, 1854. They show important affinities with taxa from the Karatau entomofauna in Kazakhstan. These groups progressively decrease and were replaced by more modern clades of Anisoptera during the Late Jurassic.

Revision of <em>Sinomesuropetala daohugensis</em> Boudet, Nel & Huang, 2023 (Odonata: Aeshnoptera: Mesuropetalidae).

The mesuropetalid dragonfly Sinomesuropetala daohugensis Boudet, Nel & Huang, 2023, is here revised based on a new well-preserved dragonfly from the Haifanggou Formation of Inner Mongolia, northeastern China. The new specimen allows us to complete the forewing characters of this species, showing the close relationship of Sinomesuropetala Boudet, Nel & Huang, 2023 with Mesuropetala Handlirsch, 1906. The mesuropetalid dragonflies are currently recorded from the Late Jurassic and Lower Cretaceous deposits of east Asia, East Central South Europe, and southern America, indicating the wide distribution and the possible long-distance migration ability of some basal aeshnopteran dragonflies during these epochs.

Beautiful wing coloration pattern in a new doratomantispine species (Neuroptera: Mantispidae) from the mid-Cretaceous Burmese amber.

A new species, namely Doratomantispa pouilloni sp. nov., of the mantidfly subfamily Doratomantispinae, is described and illustrated from a complete individual preserved in mid-Cretaceous amber from Tanai, northern Myanmar. Doratomantispa pouilloni sp. nov. preserves nearly all the diagnostic characters of this subfamily, but differs from the two other species of the genus Doratomantispa, inter alia, in its forelegs with stout trochanter, femora with nine spines on outer edge, two spines on inner edge, tibia with parallel sides, probasitarsomeres with around six pairs of black and thick spines; wings elongate and narrow, forewings with costal veinlets simple before ScP and RA fusion, coloration pattern present. Doratomantispa pouilloni sp. nov. highlights the diversity and the niche specialization of mid-Cretaceous Mantispidae from Tanai amber.

The second North American fossil horntail wood-wasp (Hymenoptera: Siricidae), from the early Eocene Green River Formation.

Eoteredon lacoi gen. et sp. nov., is described from the early Eocene Green River Formation in Wyoming, the second fossil siricid genus and species described from North America. We propose Eoteredon as sister to the genus Teredon, whose sole species is one of the rarest of extant Siricidae. The majority of siricids today inhabit temperate Northern Hemisphere forests; Teredon cubensis, however, is one of its few species that live in megathermal tropical lowlands. The Eocene forest that Eoteredon inhabited had a mesothermal to megathermal climate. We place Eoteredon in the context of broad Cenozoic climate change.
