The family Berytoniscidae is recorded for the first time from Iran and a new species, Berytoniscus persicus sp. nov. is described, and its diagnostic characters are illustrated. The specimens were collected from a solutional cave located in south of Iran. Berytoniscus persicus sp. nov. is the second species of the genus. The species displays classic troglomorphic characters, such as the absence of eyes and body pigmentation and is, therefore, considered a troglobiotic species.

A new species Laelaspis cheliceratus sp. nov. is described from the Philippines based on the materials located in Ohio State University Acarology Laboratory (OSAL) collection. Some morphological characters of two species of Berlese collection, L. regalis Berlese and L. aviator Berlese have been discussed. Laelaspis dubitatus Hunter was considered as a junior synonym of L. regalis. Some notes concerning Laelaspis dariusi and L. guilaniensis Ramroodi, Joharchi and Hajizadeh were presented in comparison with Berlese species.

Nogullocoris lemaitreae Chen & Cai, sp. nov. (Hemiptera: Heteroptera: Reduviidae: Stenopodainae) is described and illustrated based on material from the Bacan Islands, the Moluccas, Indonesia. The new species is diagnosed by the pale brown body color, the relatively long antennal scape and the straight sides of the posterior margin of the abdominal segment VII. DNA barcode of the new species and a key to the species of the genus Nogullocoris Miller, 1958 are provided to facilitate its identification. The relationship between Nogullocoris and affiliated genera is briefly discussed.

A new monospecific fossil genus of ricaniid planthoppers (Hemiptera: Fulgoromorpha: Ricaniidae), Worako gen. nov., is described with Worako yulei sp. nov. The fossil is reported from the Late Eocene Insect Bed of the Bembridge Marls, Isle of Wight, UK. It is the second record of Ricaniidae from these strata and third fossil record of Ricaniidae from the United Kingdom. The morphological characters and biogeographical importance of the fossils are briefly discussed.

Macrostemum Kolenati is the largest genus of Macronematinae, with about 106 described species, being 10 described females and only three had their female genitalia illustrated and described: Macrostemum araca Pes, Desidério, Barcelos-Silva & Hamada, 2019, M. brasiliense (Fisher, 1970) and M. scharfi Pereira & Calor, 2020. For the other seven species with described females, only the wings are illustrated. Herein, a new species of Macrostemum is discovered from the Serra da Mocidade, an isolated mountain range located in Roraima State, in the northern Brazilian Amazon. Macrostemum mocidade sp. nov. is described and illustrated based on males and females. It can be recognized as the adult male mainly by the morphology of the tergum X and phallic apparatus. Interestingly, the female of the new species have a very unusual genitalia compared to the other species in the genus, being very tapered, with a pair of cerci and two pairs of papillae very long and slender.

The genus Myrmica Latreille, 1804 from late Eocene European ambers is revised. The neotypes for M. longispinosa Mayr, 1868, M. rudis (Wheeler, 1915) and M. intermedia (Wheeler, 1915) are designated; four new species, Myrmica electrina sp. nov., M. dictyosa sp. nov., Myrmica damzeni sp. nov. and Myrmica saxonica sp. nov. are described; M. rudis and M. intermedia are recorded for Rovno amber for the first time. A key to identification of amber Myrmica species is compiled. Myrmica in mentioned ambers is the second species rich myrmicine genus. Only M. longispinosa can be assigned to the ritae-group; other ‘ritae-like’ species have either some putative plesiomorphies compared to this group, or putative apomorphy. M. electrina and M. saxonica are well distinguished from species of the ritae-group, but they are distinct from all extant Myrmica species and cannot be assigned to any modern species-groups. M. schaefersi Jessen, 2020 and M. nungesseri Jessen, 2020 from late Oligocene deposits fit well into the modern rugosa species group. In can be assumed that the putative ancestor of modern Myrmica lived in the warm forests of the early or middle Eocene, and by the late Eocene had already given rise to M. ritae-like species and other forms, and in the Oligocene species of the rugosa-group evolved.

The Ukrainian Carpathian species of the genus Hybrizon Fallén, 1813 are reviewed and illustrated. Four species are currently found in the studied region, of them H. ghilarovi Tobias, 1988 is the first record for Ukraine and H. propodealis sp. nov. is described as new from Ukraine and Belgium. An updated key to the European species of Hybrizon is provided.

Abstract. Apomorphies of the family Ephydridae and its monophyly are discussed. Revised interpretation of the male terminalia is proposed and the variability of adult proboscis is presented. Apomorphies of adults mouthparts are resulted from adaptations to microphagy, mining or algal consumption and well reflect relations among major clades. Genus Brachydeutera is transferred from Dagini to Hyadinini; subfamilies Discomyzinae and Hydrelliinae are combined; four tribes: Atissini, Lipochaetini, Ilytheini, and Dryxini are link into subfamily Lipochaetinae; tribe Hyadinini is moved to the subfamily Ephydrinae. The new phylogeny of shore flies (Ephydridae) on the subfamilial level is proposed, resulted mostly from modifications of proboscis and the male terminalia. The family is divided into four subfamilies with 19 tribes: Hydrelliinae (Discomyzini, Hydrelliini, Notiphilini, Psilopini, and Typopsilopini), Gymnomyzinae (Discocerinini, Gymnomyzini, Gastropini, Hecamedini, and Ochtherini), Lipochaetinae (Atissini, Dryxini, Ilytheini and Lipochaetini), and Ephydrinae (Dagini, Ephydrini, Hyadinini, Parydrini and Scatellini).

New inclusions found in Baltic amber allow to distinguish and describe new species of Rhabdomastix – Rhabdomastix hoffeinsi sp. nov. and provide a comparison of atypical wing venation of chosen species of this genus collectively reffered to as a group ‘R. caudata’. A new species of Rhabdomastix was determined herein with particular description and diagnosis, complete set of drawings and photographs. Thanks to new discovery, an attempt was made to explain the complete or partial preservation of crossvein r-r (R₂) in the ‘R. caudata’ group of craneflies and disscuss including the Eocene species Rhabdomastix klebsi in this group. New results give us possibilities to interpret that craneflies of ‘R. caudata’ group probably occured in fauna already in the Eocene, there is no evidence of their existence on Earth before.

Description of a new South American cerambycid species, Amethysphaerion martinsi sp. nov., is provided. The new species is illustrated and a comparative diagnosis provided. An updated key to Amethysphaerion is presented.

This paper is the eighth in a series of studies on the genus Habroloma Thomson from China, presenting the results of a collecting survey of the fauna in Hunan province, China. Nineteen species were collected and identified from twenty-eight collecting localities, eight of which are described as new species and illustrated: Habroloma (Parahabroloma) angustulum, sp. nov., H. (P.) contractiphallum, sp. nov., H. (P.) graciliforme, sp. nov., H. (P.) inusitatum, sp. nov., H. (P.) latipenne, sp. nov., H. (P.) recticolle, sp. nov., H. (P.) pseudeximium, sp. nov. and H. (P.) ruchengense, sp. nov.

Present paper is the first consolidated work on the Indian and Sri Lankan Trictenotomidae beetles, a peculiar, small and rare family of Coleoptera, providing re-descriptions, information on types, as well as images, distribution records and identification key. A total of five species (Autocrates aeneus (Westwood, 1846), Trictenotoma childreni Gray, 1832, T. grayii Smith, 1851, T. mniszechi Deyrolle, 1875, and T. templetonii Westwood, 1848) of the family Trictenotomidae have been examined from India and Sri Lanka. India harbors four species, of which three belong to the genus Trictenotoma Gray, 1832 and single species in the genus Autocrates Thomson, 1860. Sri Lanka has only one rare and endemic species, namely Trictenotoma templetonii Westwood, 1848. The lectotype for Trictenotoma aenea Westwood, 1846 (= Autocrates aeneus (Westwood, 1846)) has been designated and situation surrounding the author of Autocrates aeneus is clarified and fixed during the present study. For Trictenotoma childreni Gray, 1832, T. templetoni Westwood, 1848 and T. grayii Smith, 1851 specimens that were labelled as ‘Type’ or ‘Syntype’, were fixed as holotype by monotypy. Similarly lectotype designations have been done for Trictenotoma mniszechi Deyrolle, 1875.

To examine the relative phylogenetic position of Metoecus and Macrosiagon, we used a set of newly collected specimens of Ripiphoridae, including species not previously analysed as Ripiphorus subdipterus, R. diadasiae and Macrosiagon praeusta, along with additional Iberian specimens of Ptilophorus dufourii, Macrosiagon bimaculata and Metoecus paradoxus. Our results indicate that the inclusion of additional taxa in the analyses permitted the recovery of the reciprocal monophyly between Metoecus and Macrosiagon, as it was previously supported by morphological data. We also provide a preliminary phylogeographic analysis of Macrosiagon bimaculata aimed to discuss the large morphological variation found within the species, and a molecular analysis on the differentiation level between the Ripiphorus arabiafelix clade and its morphologically similar European counterpart, Ripiphorus subdipterus. The results of these analyses indicate that R. subdipterus is markedly different from R. arabiafelix, and R. a. arabiafelix and R. a. caboverdianus should retain their infraspecific status. The genetic variability of cox1 in M. bimaculata was not geographically structured, nor was its structure related to particular phenotypes.

Stereopalpus tsou sp. nov. (Coleoptera: Anthicidae) is described from Taiwan. This is the first record of the subfamily Eurygeniinae LeConte, 1862 from the island. The new species, considered Taiwanese endemic, belongs to the minutus informal species-group.

Two new species of the Oriental coccinellid genus Monocoryna: Monocoryna jadwiszczaki sp. nov. and M. bukidnon sp. nov. from the Philippines, are described, diagnosed and illustrated. Monocoryna nicolebertiae Ślipiński & Jadwiszczak, originally known from a single male, is redescribed based on a series of specimens of both sexes. Distribution map and an updated key to species of Monocoryna from the Philippines are also provided. Additionally, the female genitalia of M. fasciata Arrow from Malaysia are also illustrated for the first time.

(WA); E. thornorum Ślipiński and Zhou sp. nov. (WA); E. trophis Ślipiński & Zhou sp. nov. (WA.). The following new species synonymies are proposed: Psacus mastersii Macleay, 1872 = Megatoma apicalis Macleay, 1871; Trogoderma longius Blackburn, 1903 = Trogoderma singulare Blackburn, 1891;Trogoderma maurulum Blackburn, 1903 = Megatoma morio Erichson, 1842; Trogoderma tasmanica Armstrong, 1942 = Megatoma tenuefasciata Reitter, 1881b; Trogoderma debilius Blackburn, 1903 and Trogoderma adelaidea Blackburn, 1891 = Trogoderma eyrense Blackburn, 1891; Trogoderma ellipticum Armstrong, 1942 = Trogoderma antipodum Blackburn, 1891; Trogoderma inconspicuum Armstrong, 1942 = Trogoderma lindense Blackburn, 1891.Lectotypes are designated for: Megatoma apicalis Macleay, 1871; Megatoma morio Erichson, 1842; Psacus attagenoides Pascoe, 1866; Psacus callubriensis Armstrong, 1945; Psacus mastersii Macleay, 1872; Trogoderma Adelaidea Blackburn, 1891; Trogoderma alpicola Blackburn, 1891; Trogoderma antipodum Blackburn, 1891; Trogoderma apicipenne Reitter, 1881; Trogoderma baldiense Blackburn, 1891; Trogoderma blackburni Lea, 1908; Trogoderma boganense Armstrong, 1942; Trogoderma consors Arrow, 1915; Trogoderma debilius Blackburn, 1903; Trogoderma explanaticolle Armstrong, 1942; Trogoderma exsul Blackburn, 1903; Trogoderma eyrense Blackburn, 1891; Trogoderma frater Arrow, 1915; Trogoderma froggatti Blackburn, 1892; Trogoderma inconspicuum Armstrong, 1942; Trogoderma leai Armstrong, 1942; Trogoderma lindense Blackburn, 1891; Trogoderma longius Blackburn, 1903; Trogoderma macleayi Blackburn, 1891; Trogoderma maurulum Blackburn, 1903; Trogoderma meyricki Blackburn, 1891 Trogoderma nigrobrunneum Armstrong, 1942; Trogoderma nigronitidum Armstrong, 1845; Trogoderma parvum Armstrong, 1942; Trogoderma picinum Armstrong, 1945; Trogoderma reitteri Blackburn, 1892; Trogoderma rufipenne Armstrong, 1942; Trogoderma silvicolum Armstrong, 1949; Trogoderma varipes Blackburn, 1892; Trogoderma yorkense Blackburn, 1891. The interception records and available specimens of pestiferous Trogoderma species from Australia have also been reviewed and based on extensive sampling and interception records we believe that only Trogoderma variabile Ballion has been established in Australia. Both T. inclusum (LeConte) and T. glabrum (Herbst) have been intercepted in Australia but apparently failed to establish viable populations and should be treated as absent from Australia.

The publication recalls the figure of the world-famous traveler and ethnographer, Jan Kubary, who worked for the Godeffroy Museum in Hamburg. Kubary provided European natural history museums with extremely valuable research materials constituting the basis of the 19th century systematic studies of the animals of Oceania including numerous descriptive types of species new to science. The results of the query of ornithological collections of the Museum and Institute of Zoology of the Polish Academy of Sciences in Warsaw revealed the presence of 17 bird specimens from Oceania collected by Jan Kubary. They were transited to the current collection from the collection of the Warsaw Zoological Cabinet and the Branicki Museum. These specimens are valuable voucher materials for studies in the field of museology and the history of zoology, and, due to the specific method of preparation, currently offer the possibility of conducting systematic research based on genetic data (historical DNA).
