A new species, Dorytomus groehni Bukejs & Legalov sp. n. is described and illustrated from Eocene Baltic amber. The new species differs from D. nudus Legalov, 2016 primarily in longer and wider body size, narrower and longer rostrum, slightly convex interstriae distinctly wider than elytral striae and finely punctate pronotum with semierect setae.

A new species of comb-clawed beetles of the genus Asiomira Dubrovina, 1973 (A. dubrovinae sp. n.) is described from the Eocene Baltic amber. This newly descovered fossil species displays typical generic characters and is the most similar to the extant Asiomira ophtalmica (Seidlitz, 1896). Both species share a similar shape of the pronotum and the flattened posterior angles of the pronotal disc. Asiomira dubrovinae sp. n. can be distinguished from A. ophtalmica by the smaller body size (4.8 mm in contrast to 6–8.12 mm), more serrate antennomeres, and finer and sparser pronotal punctation. Extant species of the genus are distributed in the arid landscapes of Central Asia with the highest diversity occurring in Tajikistan. Therefore the discovery of a new fossil species from Eocene Baltic amber suggests that Asiomira could have a wider range, and the modern distribution of this group is the result of a later secondary expansion of the ancestral representatives that survived in mid-mountain areas with arboreal and shrub vegetation. Relevant corrections to the distribution of extant species, Asiomira ophtalmica (Seidlitz, 1896) and Asiomira firjusana (Dubrovina, 1973), are given.

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.

A new species of the extant spider family Anapidae is described from a fossil mature male in Eocene amber from the Baltic region and tentatively assigned to the genus Balticoroma Wunderlich, 2004. Phase contrast X-ray computed micro-tomography was used to reveal important features that were impossible to view using traditional microscopy. Balticoroma wheateri new species is easily diagnosed from all other anapids by having clypeal extensions that run parallel to the ectal surface of the chelicerae and in having the metatarsus of the first leg highly reduced and modified into what is presumably a y-shaped clasping structure. Although only a single extant anapid species occurs in northern Europe, the family was diverse in the Eocene. The discovery of yet another anapid species in Baltic amber supports the idea that Eocene European forests may have been a hotspot of evolution for this family of spiders.

A new species of the genus Holoaden is described from the Atlantic forest of the state of São Paulo, Brazil, being restricted to primary or slightly disturbed high altitude cloud forests along the northeastern portion of the Serra do Mar. The typelocality is determined as Estação Ecológica de Bananal, in the Municipality of Bananal, State of São Paulo, Brazil. The new species is characterized by its moderate body size (female 42.6–44.2 mm SVL; male 37.2–38.5 mm SVL) with long and slender limbs, a head wider than long, a highly glandular dorsum, covered by well developed macroglands that extend to the internasal region, thigh and tibia, and an intense dark brown dorsal coloration and dark grey ventral surface.

Parapteronemobius contains 7 species or subspecies distributed in East Asia with only one species recorded from China. In this study, we reported the second species, P. chenggong He sp. nov., from Zhejiang. The new species differs from P. dibrachiatus in body size, male genitalia and COI gene. The phylogeny of this genus in subfamily Nemobiinae are discussed based on COI, 18S and 28S genes. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

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.

Species of the megadiverse ground beetle tribe Platynini occur on all continents except Antarctica. It has been long recognized that platynine beetles were preserved in the Eocene Baltic amber. However, thus far only a single Eocene fossil has been described to the species level. In the present paper, a new species of Platynini known only as an amber inclusion fossil is described and imaged using light microscopy and micro X-ray computed tomography. Since this species cannot be assigned to any of the recently described genera, the monotypic genus Praeanchodemus gen. n., with the type species P. punctaticeps sp. n., is erected. There is some evidence from external morphology that Praeanchodemus gen. n. is part of a lineage comprising the recent genera Paranchodemus, Rhadine, and Tanystoma. However, since some synapomorphies were not found, the true relationships of the fossil taxon remain moot.

A new species of oribatid mites (Oribatida) phoretic on the beetle, Macrolinus batesi (Coleoptera, Passalidae) is described from Sumatra, Indonesia. Graptoppia (Stenoppia) royi sp. nov. (Oppiidae) differs from G. (S.) italica by the smaller body size, the presence of thin transcostula and the absence of costulae. Data on oribatids phoretic on passalid beetles are summarized; nine identified oribatid species (from 19 beetle species) are listed.

A new species of Ituglanis is described from rio Iratapuru, near the rio Jari, Amapá, Brazil. The new species is distinguished from all congeners by the reduced number of post-Weberian apparatus vertebrae (36 or 37); the low number of paired ribs (2); the low number of interopercular odontodes (12–15); the number of branchiostegal rays (7 or 8); the presence of elongated fontanel in parieto-supraoccipital; the pectoral-fin rays (i,5); head length (18.9–25.0); and the presence of pores supraorbital s1, infraorbitals i1 and i3 of the laterosensory system. The new taxon has a reduced body size and fully ossified skeleton, but does not display a large number of paedomorphic traits compared to congeners. Comments about taxonomy and intrageneric comparisons are made, and paedomorphic in Ituglanis is discussed. Thoughts about conservation of the new species are presented.

A new species of the extinct scydmaenine genus Euroleptochromus Jałoszyński (Mastigitae: Leptochromini), E. tuberculatus Yin & Cai, sp. nov., is described from Eocene Baltic amber. It can be separated from the two previously known congeners by the different proportions of the body parts and spination of the profemur, and more importantly, lack of an elongate postgenal process of the head. Our finding demonstrates for the first time a notable variability of the postgenal structures within Euroleptochromus.
