Nine species of the genus Hebarditettix are found in Vietnam; H. chamensis sp. nov., H. fuscus sp. nov., H. gibbus sp. nov., H. intermedius sp. nov., H. magnus sp. nov., and H. oculatus sp. nov. are described from this country. A key to Vietnamese species of Hebarditettix is provided.

Four species (Rhyparida spiridonovi sp. nov. from Penang Island and Singapore, Tricliona trimaculata sp. nov. from Penang Island and Malay Peninsula, T. suratthanica sp. nov. and T. trangica sp. nov. from Thailand) are described. A key to the species of the genus Tricliona from Indochina and Malay Peninsula is given. Rhyparida faitsilongi nom. nov. is the new replacement name for Rhyparida megalops (Chen, 1935), comb. n., transferred from the genus Tricliona; Tricliona tonkinensis (Lefèvre, 1893), comb. nov. and Tricliona episternalis (Weise, 1922), comb. nov. transferred from the genera Phytorus and Rhyparida, accordingly. Lectotypes of Rhyparida episternalis Weise, 1922 and Phytorus tonkinensis Lefèvre, 1893 are designated.

A new species Callopora septentrionalis sp. nov. of cheilostome Bryozoa is described from the collection of the Zoological Institute, Russian Academy of Sciences. The species differs from its congeners by presence on gymnocyst of three types of adventive avicularia: two columnar avicularia with triangular mandible of different sizes as well as large avicularia with spatulate mandible, and by bell-shape and cap-shape ovicells.

Microrhagus nikitskyi sp. nov. and M. vicarius sp. nov. are described from the Russian Far East. Based on the holotype, Balistica elongata Fleutiaux, 1923 is re-described. The following new combinations are proposed: Clypeorhagus elongatus (Fleutiaux, 1923), comb. nov. (= Balistica elongata Fleutiaux, 1923) and Dirrhagofarsus ferrugineus (Reitter, 1889), comb. nov. (= Dirrhagus ferrugineus Reitter, 1889). A new synonym is established: Dirrhagofarsus Fleutiaux, 1935 = Pseudorhacopus Olexa, 1975, syn. nov. Lectotypes of Microrhagus pyrenaeus Bonvouloir, 1872 and Dirrhagus ferrugineus Reitter, 1889 are designated; status and distribution of these species are discussed.

Investigation of Eriosomatidae in Belarus started in the 1900s. However, a regional checklist of Eriosomatidae aphids was not published till now. Based on material preserved in the collections of Belarusian State University and the Zoological Institute of the Russian Academy of Sciences, and data scattered across publications we have compiled the first comprehensive list of Eriosomatidae recorded from Belarus and briefly analysed it from the geographical and ecological points of views. The list includes 12 genera and 27 species. Pemphigus passeki Börner, 1952 has been recorded from Belarus for the first time. The registered diversity is less abundant than in the adjacent Poland. In the accordance with the global pattern of aphids host plant connections, a single species permanently inhabit woody plants (monoecious species), the other ones are dioecious and migrate from woody plants to woody (eight species) or herbaceous (12 species) plants. Four species is anholocyclic.

Mirococcus vallis sp. nov. is described and illustrated from Samara Prov. of Russia. Three else species of mealybugs: Fonscolombia amnicola (Borchsenius, 1948), Mirococcopsis subterranea (Newstead, 1893) and Ripersiella poltavae (Laing, 1929) are reported for the first time to the fauna of the Volga Area.

An annotated list of robber flies (Diptera: Asilidae) occurring in Belarus is presented based on the original material and published data. Totally 36 species are recorded, 35 of them based on the author’s material. Ten species are recorded from Belarus for the first time.

A new species of the genus Parasmittina Osburn, 19521, P. tatianae sp. nov., is described and illustrated. It was obtained from a surface of mollusk shells in the south-eastern part of the Chukchi Sea. The new species differs from congeners in the size of zooids, in the shapes of the primary orifice and peristome and in the morphology of the lyrula and the condyles.

A replacement name, Encarsia flagellata nom. nov., is proposed for E. antennata Myartseva, 2014, a junior homonym of E. antennata Myartseva, 2008.

Peracca omissa sp. nov. and P. derelicta sp. nov. from western part of Malaysia are described. These species are very similar to P. conspicuithorax Griffini, 1897 and P. mirzai Tan et Ingrisch, 2014 but differs from them in the shape of some male abdominal structures. Peracca macritchiensis Tan et Ingrisch, 2014, syn. nov. from Singapore is synonymized to P. tiomani Gorochov, 2011 described from Tioman I. near southern part of Malacca Peninsula.
