Two species from a Baltic amber sample of the late Eocene Period, described earlier in the genus Bryocrypta, are attributed to the genus Rovnodidactylomyia (R. girafa (Meunier, 1904) comb. n. and R. capitosa (Meunier, 1904)). The first fossil species of the genus Didactylomyia is described for the first time; two contemporary Palaearctic species are recorded. Keys to the species of the genus Didactylomyia are given.     

A review of species of the genus <Emphasis Type="Italic">Diaphorus</Emphasis> (Diptera,Dolichopodidae) in the Palaearctic Region

The history of studying the genus Diaphorus is described. Seventeen species have been studied. A key to species of the genus Diaphorus of the Palaearctic fauna, including 37 species, and a catalogue of the Palaearctic species with synonyms are given. Diaphorus oldenbergi Parent, 1925 is regarded as a synonym of the species D. nigrotibia Strobl, 1893 (syn. n.). The new species Diaphorus sublautus sp. n. from Azerbaijan is described. Lectotypes of D. dolichocercus Stackelberg, D. parenti Stackelberg, D. ussuriensis Stackelberg, and D. varifrons Becker are designated.     

Phylogenetic relationships of the genus <Emphasis Type="Italic">Armadolepis</Emphasis> Spassky, 1954 (Eucestoda,Hymenolepididae), with descriptions of two new species from Palaearctic dormice (Rodentia,Gliridae)

Two new species of hymenolepidid cestodes belonging to the genus Armadolepis Spassky, 1954 are described from dormice (Gliridae) from the southern East European Plain and the northwestern Caucasus, Russia. Armadolepis (Bremserilepis) longisoma n. sp., with a rudimentary, unarmed rostellar apparatus is described from the fat dormouse Glis glis (Linnaeus) from the Republic of Adygeya, Russia. Additionally, A. (Armadolepis) dryomi n. sp., characterised by a well-developed rostellar apparatus and armed rhynchus is described from the forest dormouse Dryomys nitedula Pallas from Rostov Oblast’, Russia. Armadolepis (Bremserilepis) longisoma n. sp. differs from A. (Bremserilepis) myoxi (Rudolphi, 1819) in having a substantially longer strobila and cirrus-sac, wider scolex and ovary and larger rostellar pouch and testes. Armadolepis (Armadolepis) dryomi n. sp. is distinguishable from A. (Armadolepis) spasskii Tenora & Baru?, 1958, A. (Armadolepis) jeanbaeri Makarikov, 2017 and A. (Armadolepis) tenorai Makarikov, 2017 in having a substantially longer and wider strobila, and larger rostellar pouch and cirrus-sac. Furthermore, A. dryomi n. sp. can be distinguished from its congeners by the number and size of rostellar hooks and the arrangement of the testes. Phylogenetic affinities of Armadolepis were studied for the first time using partial sequences of the nuclear ribosomal 28S DNA gene. Phylogenetic analysis strongly supported the status of Armadolepis as a separate genus belonging to the “Rodentolepis clade”.     

On the northernmost distribution of leaf beetles of the genus <Emphasis Type="Italic">Oreomela</Emphasis> (Coleoptera,Chrysomelidae): New species from mountains of southern Siberia

Three new species of leaf beetles are described: Oreomela dudkorum sp. n. (Terektinskii Ridge, Central Altai Mountains), O. tuvensis sp. n. (mountains of southeastern Republic of Tuva), and O. romantsovi sp. n. (Western Sayan Mountains). The representatives of this genus, and especially of the nominotypical subgenus, were found in Russia and in the territories mentioned for the first time. Thus, the distribution boundary of this genus is shifted 3–4° northwards. The representatives of Oreomela have most probably migrated from Tien Shan to the mountains of southern Siberia via the Mongolian Altai Mountains.     

On the taxonomic position of <Emphasis Type="Italic">Issus reticulatus</Emphasis> Bervoets, 1910 (Hemiptera: Fulgoroidea: Issidae) from Baltic amber

A new genus Bolbossus gen. n. is erected in the tribe Parahiraciini for Issus bervoetsi Gnezdilov et Bourgoin, nom. n. pro Issus reticulatus Bervoets, 1910 (nom. praeocc., non Issus reticulatus Herrich-Schäffer, 1835) described from the Baltic amber of Kaliningrad Province in Russia. The genus Issites Haupt, 1956 is assigned to the nominotypical subtribe of the tribe Issini Spinola. Bolbossus bervoetsi (Gnezdilov et Bourgoin) is the first species of the Oriental tribe of the family Issidae discovered in Europe. This finding implies the dispersal of taxa from the Oriental Region to the Western Palaearctic during the Eocene. Other fossil Issidae are briefly discussed.

A key to the new and closely related species is given to supplement that published in the third part of the revision (Kasparyan, 2015). The other 25 species of the genus Rhorus from the collection of the München Museum is given; some of the species are recorded for the first time for France, Italy, Germany, Netherlands, Poland, Moldova, and Armenia.     

A new species of the genus <Emphasis Type="Italic">Eusarima</Emphasis> Yang (Hemiptera: Fulgoroidea: Issidae) from Pakistan

Eusarima albifrons sp. n. is described from northern Pakistan (Islamabad). The new species is closely related to Eu. iranica Gnezdilov et Mozaffarian, 2011 and may be distinguished by details of coloration and male genital structure. This is the second species of the genus Eusarima Yang recorded from the Western Palaearctic. Parasarima triphylla Che, Zhang et Wang, 2012 is transferred to the genus Eusarima, which is thus recorded for the first time from continental China. The homologies in the genital structures of males and females are discussed for some genera of Oriental, Palaearctic, and Afrotropical Issidae.     

Two new species of the family Suctobelbidae (Acari,Oribatida) from Chile

Two new species of the oribatid mite family Suctobelbidae (Acari, Oribatida) are described from southern Chile. Niosuctobelba sphagnicola Ermilov, sp. n. differs from N. ruga Chinone, 2003 in the rostrum with a median incision and one pair of lateral teeth, the heads of bothridial setae rounded distally, the tectopedial fields not fused anteriorly, the notogastral setae barbed, and the body without striate ornamentation. Zeasuctobelba tierradelfuegoensis Ermilov, sp. n. differs from Z. trinodosa Hammer 1966 in a shorter body, the heads of the bothridial setae with thin apices, the tectopedial fields not fused anteriorly, and the notogastral humeral tubercles with longer cristae. An identification key to the known species of Zeasuctobelba is given. The genus Niosuctobelba is recorded for the Neotropical Region for the first time, while Zeasuctobelba is new to the fauna of Chile.

A synopsis of gall midges associated with conifers,with description of a new species of the genus <Emphasis Type="Italic">Kaltenbachiola</Emphasis> Hedicke (Diptera,Cecidomyiidae: Lasiopterinae) from Yakutia,damaging cones of the Siberian spruce (<Emphasis Type="Italic">Picea obovata</Emphasis>)

The world fauna comprises 134 species from 52 genera of gall midges associated with plants of the order Pinales (3 families, 16 genera and 74 species); 14 genera are specific to Pinales. The distribution of genera and species of gall midges over host plant taxa is described. The Holarctic genus Kaltenbachiola comprises four species all developing in the spruce (Picea spp.) cones. Earlier, K. strobi (Winnertz), widely distributed in Europe, was the only species known in the Palaearctic. A new species Kaltenbachiola anastasiae sp. n. is described, which damages cones of Picea obovata in Central Yakutia. The phylogenetic relationships of Kaltenbachiola with close genera specific to Pinales are characterized, and an updated diagnosis of the genus with additional morphometric parameters and keys to the pine-specific genera of the tribe Dasineurini and to species of the genus Kaltenbachiola are given. The host associations and specific traits of biology and distribution of Kaltenbachiola species are considered.
