Abstract: The relationship of Xylomoia strix Mikkola, 1980; Xylomoia retinax Mikkola, 1998; and Xylomoia stangelmaieri Mikkola, 1998 is reconsidered based on 59 genitalia slides (37 males and 22 females) and 40 barcodes of adults collected from the type localities and areas in-between. Due to lack of stable morphologic differences, apart from the wing coloration of X. retinax, and low genetic distance between the three, they are considered as three subspecies of X. strix: the nominotypical one X. strix stangelmaieri stat. nov. and X. strix retinax stat. nov. Included are photographs of all specimens covering 37 adults, and 28 male and 18 female genitalia, as well as a phylogenetic tree and a map showing collecting localities.

Abstract: A fundamental prerequisite for understanding and protecting biodiversity is the construction of a high-quality faunal database. The primary objective of this study was to address knowledge gaps in the biodiversity of the family Psychodidae in Estonia. Faunistic data on 45 species of moth flies (Diptera: Psychodidae) from Estonia are presented, including 30 new country-records. Sixteen species are considered important for nature conservation. An updated checklist of the family, comprising 71 species, is provided for the Baltic countries. Habitus photographs of selected Estonian species are also included.

Abstract: Two new species of Bryocamptus Chappuis, 1929 from the Russian Arctic from the Bryocamptus minutus species group are described: Bryocamptus putoranus sp. nov. and Bryocamptus abramovae sp. nov. A complete morphological comparison of the new species with the type species Bryocamptus minutus (Claus, 1863) was carried out. Significant interspecific differences were shown at the level of microcharacters, such as integumental sensillae and pores, ornamentation of segments of mouthparts and swimming legs, and pores on swimming legs. A significant correlation has also been shown in the shape of the caudal rami of the females and the antennules of the males, which is likely caused by an evolutionary sexual arms race. Bryocamptus putoranus sp. nov. and B. minutus have a similar structure of caudal rami, but completely different male antennules, which may indicate a convergent origin of modifications and highlights the importance of depicting male antennules in the species descriptions.

Abstract: A morphological and molecular study of 17 Cylindrotomidae species revealed that the two subspecies of Cylindrotoma distinctissima, the Nearctic C. americana Osten Sacken, 1865, stat. reval. and the Palearctic C. distinctissima (Meigen, 1818), represent separated lineages and consequently are raised to species level. Cylindrotoma japonica Alexander, 1919, syn. nov. and C. distinctissima alpestris Peus, 1952, syn. nov. are now known to be junior synonyms of C. distinctissima. Triogma kuwanai limbinervis Alexander, 1953, syn. nov. and T. nimbipennis Alexander, 1941, syn. nov. are now placed into synonymy under Triogma kuwanai (Alexander, 1913). The Japanese Cylindrotomidae are all redescribed and all available literature and distribution data are summarised. Supplementary descriptions and illustrations for male and female terminalia of Cylindrotoma nigriventris Loew, 1849, Diogma dmitrii Paramonov, 2005, Liogma nodicornis (Osten Sacken, 1865), Phalacrocera replicata (Linnaeus, 1758), P. tipulina Osten Sacken, 1865, and Triogma trisulcata (Schummel, 1829) are provided. The following new distribution records are outlined; Diogma caudata Takahashi, 1960 from Arkhangelsk Oblast, Russia; D. glabrata (Meigen, 1818) from Belarus, Latvia, and Altai Republic, Amur Oblast, Novgorod Oblast, Magadan Oblast, Samara Oblast, and Kuril Islands (Shikotan I and Paramushir I) in Russia; Liogma serraticornis Alexander, 1919 from Khabarovsk Krai, Russia; Phalacrocera replicata from Khabarovsk Krai, Russia; and the presence of Cylindrotoma nigriventris in Altai Republic, Russia is confirmed.

Abstract: An overview of the Estonian terrestrial isopod fauna is given, based on literature data and material collected from 1984 to 2021. The identified material consisted of 10915 specimens belonging to 14 species and collected from 172 localities throughout Estonia. In combination with previous data from the literature data, there are now reliable records of 16 species of woodlice from Estonia. Two species, viz. Platyarthrus hoffmannseggii Brandt, 1833 and Hyloniscus riparius (C. Koch, 1838), are new for the fauna. The latter has probably colonised Estonia recently and range expansions have been reported elsewhere. The data on Philoscia muscorum (Scopoli, 1763) are dubious, and this species is currently excluded from the Estonian list.

Abstract: The data on Estonian Myriapoda are scattered in various publications and there has been no overview of the fauna up to the present. A critical summary of the previous information on Estonian Myriapoda is given, supplemented by new records and distribution maps. Altogether, 5784 specimens from 276 collecting sites were studied. To the hitherto recorded 14 centipede species are added Lithobius melanops, L. microps, Geophilus carpophagus, G. flavus, Strigamia transsilvanica and Stenotaenia linearis, a probably introduced species. Of the 27 published Estonian millipede species, the data on two species proved erroneous, and two new species were recorded (Craspedosoma raulinsii and Cylindroiulus britannicus). Two previously recorded millipede species – Brachyiulus pusillus and Mastigophorophyllon saxonicum – were not found in the recent samples, the latter may have become more rare or extinct. Pauropoda and Symphyla lack previous reliable records. Combined with published data, the number of myriapod species known from Estonia is now set at 52. Some changes in species distribution and frequencies were detected comparing the published data with new records. Some data about habitat preferences of the more common species are also given. The majority of species have a western Palaearctic distribution, while six species are at the northern limit of their ranges.

Abstract: The Chrysididae are a group of cleptoparasitic and parasitoid aculeate wasps with a large number of rare and endangered species. The taxonomy of this group has long been confusing due to the similarity of species and extensive intraspecific variation. We present for the first time a comprehensive dichotomous key for all 74 species found in the Nordic and Baltic countries. In addition to diagnostic characters, information on the distribution and biology of each species is also presented. A new species, Chrysis borealis Paukkunen, Ødegaard & Soon, sp. n. is described on the basis of specimens collected from Fennoscandia. Chrysis gracillima Förster, 1853 is recorded as new to the Nordic and Baltic countries.

Abstract: Two new Mycetophilidae species, Neuratelia jabalmoussae sp. n. and Neuratelia salmelai sp. n. are described on the basis of material collected from Lebanon, Estonia and Finland. Detailed figures of male terminalia and photographs of general facies are provided along with discussions of their morphological distinction from sibling species. For the first time molecular characters are used to distinguish new fungus gnat species. Molecular analysis relies on cytochrome oxidase subunit one (COI) but has additionally been corroborated by information from the 28S and ITS2 regions of nuclear ribosomal DNA. Situations where morphological and molecular data provide conflicting evidence for species delimitation are discussed. A new country record from Georgia is provided for Neuratelia caucasica.
