Libanonemopalpus grimaldii gen. et sp. nov. is characterised, illustrated, and described from the lower Barremian amber of Bqaatouta (Lebanon). It represents the earliest record, the first and only Bruchomyiinae psychodid with functional piercing mouthparts. The discovery of this Cretaceous psychodid fly improves our knowledge of the palaeobiodiversity of Bruchomyiinae and particularly on the evolution of mouthparts in this group.

The Aix-en-Provence Formation is an Oligocene (22.5 Ma) Lagerstätte in southern France that contains an abundance of soft-bodied fossils preserved in exceptional detail. Many taxa have been described from this formation, including insects, spiders, fishes, and plants, suggesting a diverse ecosystem in a subtropical, brackish, lacustrine paleoenvironment. Fossil spiders from this deposit are preserved as compression fossils and internal and external molds. Recently, compression fossils of spiders from Aix-en-Provence were hypothesized to be a product of a taphonomic pathway based on diatoms and sulfurization. Here, we examine fossil spiders preserved as molds to uncover a second taphonomic pathway based on microbial mats. Evidence of microbial mats include wrinkles, pustular textures, and possible microbial mat chips on the bedding surfaces as well as a matrix fabric that contains possible microbial sheaths and bacterial spherules. The evidence presented here supports prolific microbial mat communities during deposition of the Aix-en-Provence Formation, and suggests that they are likely responsible for the moldic preservation of the spiders. Our work shows that the paleoenvironment of the Aix-en-Provence Formation promoted at least two possible taphonomic pathways that resulted in the differing modes of preservation observed.

Eocicadellium grimaldii gen. et sp. nov., the oldest representative and first Triassic member of the subfamily Karajassinae Shcherbakov, 1992, is described on the basis of six forewings from the Middle-Upper Triassic Yanchang Formation of northern China, widening the duration and biogeographic distribution of this extinct subfamily. The new data represents the first known definite record of Karajassinae in China, and further explores the palaeodiversity of Triassic archijassids.

Two early Eocene damselfly taxa Eopodagrion scudderi Cockerell, 1921 and Eopodagrion ‘Podagrion’ abortivum (Scudder, 1878) are redescribed and refigured. Their phylogenetic relationships are discussed. Although they could likely belong to the Coenagrionidae, their exact affinities remain uncertain because of the presence of homoplasies affecting crucial characters among the Zygoptera.

Ricinulei Thorell, 1876 is an order of Arachnida currently represented in the New and Old Worlds by 103 living species. The order is also represented in the fossil record from the Carboniferous (ca. 305–319 Ma) and the Cretaceous (ca. 99 Ma) periods. In the present contribution, Hirsutisoma grimaldii sp. nov., a new extinct species of the suborder Primoricinulei Wunderlich, 2015, is described from a specimen preserved in Cretaceous Burmese amber. The specimen is a well-preserved adult male in which several taxonomically informative structures are visible, allowing the new species to be differentiated from Hirsutisoma bruckschi Wunderlich, 2017, the only other congener for which a male is known. This description raises the number of Cretaceous Ricinulei species to six. A comparative table documents morphological differences among the various species of this lineage. Hypotheses concerning the paleoecology and functional morphology of this species and, by extrapolation, other primoricinuleids, are presented. The evidence suggests that Primoricinulei were corticolous, scansorial predators.

The family Palleptoceridae fam. nov. is proposed as a new extinct family of the superfamily Leptoceroidea. It is characterized by the absence of ocelli, the presence of five-segmented maxillary palps in both sexes, antennae longer than the forewings, and the tibial spur in the form of 2/4/4. The extinct Palleptoceridae is closely related to the leptoceroid family Leptoceridae, but the formula for the adult tibial spur is reduced from 2/4/4 to 2/2/4 (Morse, 1981). The Palleptocerus grimaldii sp. nov. from the mid-Cretaceous Burmese amber is furthermore characterized by the sexual dimorphic wing venation. In the forewings, the apical forks I and V are present in the male and forks I, III, and V in the female; in the hind wings of both sexes, exclusively the apical fork V is present. The Leptoceroidea originated and evolved in Gondwana. Palleptocerus grimaldii sp. nov. is interpreted as a relict species of the Gondwanan Leptoceroidea in Burmese amber.

A new species, Eltxo grimaldii sp. nov., is described from Spanish Lower Cretaceous (middle Albian) amber from El Soplao, based on a single female. The new species is compared with the other only known species of the genus, Eltxo cretaceus Arillo & Nel, 2000, based on a single male specimen also found in Spanish amber, but slightly younger (Peñacerrada I amber; upper Albian). The holotype of E. cretaceus is reviewed and its description corrected and expanded, providing the first micrographs of its anatomical features. The holotype of the new fossil species is the only female specimen known of the cecidomyiid tribe Amediini Jaschhof, 2021, a tribe recently described after changes of taxonomic attribution of the genus Eltxo during the last 20 years.

The family Dolichopodidae (Diptera) from the Eocene amber of the Cambay and Kutch, India is reviewed. Based on a sample of 38 inclusions, the fauna preserved in amber reveals that the family was well-differentiated by early the Eocene. Palaeomedeterus cambayensis Bickel sp. nov. is described and provisionally assigned to the Peloropeodinae, and is congeneric with European Baltic amber species, suggesting the genus was widespread for a considerable time period in both Europe and India. Two small-sized new monotypic genera are also described, Gujaratmyia rotunda Bickel gen. et sp. nov. and Rajpardia grimaldii Bickel gen. et sp. nov. Also included are undescribed members of the dolichopodid subfamilies Diaphorinae and Medeterinae, and unplaced species. The Baltic amber species Prohercostomus noxialis (Meunier, 1907) is regarded as the new senior synonym of Sympycnites primaevus Grimaldi & Cumming, 1999, described with a mistaken provenance of Cretaceous Lebanese amber.

Docidiadia grimaldii sp. nov., the second known species in the genus, is described based on a holotype female and on a female paratype. The differences with D. burmitica Blagoderov & Grimaldi, the type-species of the genus, are discussed. The specimens allow the study of important details of the antenna, wing, and terminalia. The question of the connection of Docidiadia to the extant family Diadocidiidae is addressed. An antenna with the flagellum more slender towards the apex is also known in the extinct sciaroid family Archizelmiridae, but the wing venation of Docidiadia is much more conservative than the wing in archizelmirid genera.
