The scarce fossil wood record of Proteaceae is complemented with the addition of a new morphogenus with two new species from the Oligocene of Patagonia, Scalarixylon patagonicum, gen. nov., sp. nov., and S. grandiradiatum, gen. nov., sp. nov. They become the first two fossil species that have all the typical characteristics of Proteaceae wood anatomy: wide multiseriate rays, tangential bands of vessels with unilateral banded associated parenchyma and simple perforation plates. They seem to be related to extant species that inhabit the subantarctic forests of Patagonia.

Leaves of three species belonging to the family Araucariaceae are described from two Eocene localities in Tasmania. Araucarioides gen. nov. is proposed to contain the fossil species. The erection of a new genus is necessary for two reasons. Two new species, A. linearis and A. sinuosa, are intermediate between Agathis and Araucaria and do not have the Florin rings which are the characteristic of extant species of Araucariaceae. The third new species, A. annulata, while clearly belonging to the Araucariaceae, is not well enough preserved to be assigned to an extant genus. These species confirm the presence of the subtropical/tropical Araucariaceae in Tasmania in the Eocene. The evolutionary position of the fossil species is uncertain at present.

Lonchodryinus groehni sp. nov. (Hymenoptera: Chrysidoidea: Dryinidae) is described from Baltic amber. The new species is close to L. balticus Olmi & Guglielmino, 2012, but it can be distinguished for the different OPL/POL ratio and 2r-rs&Rs vein of the fore wing. A key to the fossil species of Lonchodryinus and a comparison with the extant species L. ruficornis (Dalman, 1818) are presented.

ABSTRACT Phloeocharinae is a small and likely non-monophyletic subfamily of rove beetles. The enigmatic genus Charhyphus Sharp, 1887 has long been placed in Phloeocharinae, whereas recent studies have found it to be phylogenetically very distant from the core members of this subfamily, suggesting the possibility that it actually deserves its own separate subfamily status. So far, the sole definitive fossil record for Charhyphus is known based on a single male from Eocene Baltic amber as represented by †Charhyphus balticus Shavrin, 2020. Here, we describe and illustrate another new Charhyphus species, †Charhyphus serratus sp. nov. Yamamoto & Shavrin, from Baltic amber based on a well-preserved female fossil. Considering the general proportions of the body and the head, this new species is most similar to †C. balticus. The new species differs from all known species by the development of strong serration of the lateral edges of the pronotum and features of the shape of the apical margin of the mesoventrite. By using X-ray micro-computed tomography, we succeeded in visualising not only the general habitus but also each individual body part, recovering a previously undocumented sclerite on the female internal genital segments in the genus. Morphological features of extinct and extant species of Charhyphus are briefly discussed. Figures of all extant Charhyphus species and a key for the genus are also provided. Our study is important for considering possible higher palaeodiversity, more common occurrence, and palaeobiogeography of Charhyphus.

Two new species, Itaphlebia exquisita sp. nov and Itaphlebia laeta sp. nov., were collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou, Inner Mongolia, China. A key to the species of the genus Itaphlebia is provided and diagnosis of the genus is revised. Itaphlebia exquisita sp. nov differs from other species in having an extra medial vein branch. Itaphlebia laeta sp. nov shows a transitional character to the extant genera by having a simple Sc. These new findings expand the distribution of Itaphlebia from middle-southern Russia to northeastern China.

Modiomytilus n. gen. is described from Tertiary sediments exposed in the southwestern corner of Santa Cruz province (Argentina). This large mytilid is characterized by its ornamentation of strong comarginal undulations, its smooth ligamentary ridge, and its relatively large anterior adductor muscle. Two new species are assigned to it: Modiomytilus argentinensis n. sp., from the Centinela Formation (Miocene) south of Lago Argentino, and Modiomytilus mercerati n. sp., from the Río Turbio Formation (Eocene) in Sierra Dorotea. Although other species belonging to this new taxon and previously referred to Mytilus have been described from Tertiary sediments in the region, none are known so far from rocks of comparable age outside Patagonia.

Two new species of the cosmopolitan genus Metatrichia Coquillett are described. Metatrichia dhimurru sp. nov. is described from Arnhem Land (Northern Territory), Australia and represents the third species of the genus to be described from the Australasian region. Metatrichia venezuelensis sp. nov. from Venezuela is the third extant species of the genus to be described from the New World.

Culiseta kishenehn, sp. n. and Cs. lemniscata, sp. n. (Diptera: Culicidae: Culisetini) are described from compression fos-sils from the 46 million year old Kishenehn shale deposits in Montana, USA. The new species appear to share featureswith extant species of subgenera Climacura and Culicella, respectively. The antiquity of Culiseta is examined and previ-ously described Eocene fossil species are discussed. Eoaedes gen. n. and Aetheapnomyia gen. n. are established for Aedes damzeni Podėnas and Ae. hoffeinsorum Szadziewski, two Eocene fossil species in Baltic amber.

Two new species of the lineomaculatus clade of the Liolaemus lineomaculatus section are described from southern Patagonia in Argentina. Liolaemus morandae sp. nov. is found in S Chubut province and Liolaemus avilae sp. nov. inhabits NW Santa Cruz province. Several tests were performed to diagnose these new species as distinct lineages. Univariate analysis of variance (ANOVA), principal component analysis (PCA), discriminant function analysis (DFA), non-parametric multivariate analysis of variance (NPMANOVA), as well as a genetic characterization through molecular analysis of variance (AMOVA) were performed; genetic distances between described and these new species are reported. The new Liolaemus species differ from other members of the lineomaculatus group in morphometric, meristic, qualitative and genetic characters; moreover they inhabit different phytogeographical provinces and districts. With these descriptions, the number of species now recognized in the lineomaculatus section is twenty one (including one more description that is in press).

A new fossil species of fairyfly (Hymenoptera: Chalcidoidea: Mymaridae) is described and figured from a well-preserved female in middle Eocene (Lutetian) Baltic amber as Borneomymar pankowskiorum Engel, McKellar, & Huber, new species.  This species represents the fourth genus from Baltic amber whose extant species now occur only in southeastern Asia, Australia and Madagascar.

Masona popeye Quicke & Chaul sp. n. is described from Brazil, and differentiated from other species of the genus. Described extant species of Masona are known from Australia and south eastern U.S.A. (Georgia and Florida including the Key Islands). Two undescribed species are known from Tanzania and Cambodia. The new species is therefore the first representative of the subfamily Masoninae van Achterberg from South America, demonstrating the completely cosmopolitan distribution of this very poorly known group. The new species most closely resembles a fossil species, M. pyriceps van Achterberg, 2001, from Dominican amber with which it shares the plesiomorphic presence of a scutellum.
