A new phylogenetic hypothesis is proposed for the relationships among the species within the genus Docosia Winnertz, 1863, based on a combined analysis of five DNA markers (28S, ITS2, COI, COII and CytB). Five new species are described, Docosia anatolica Ševčík sp. nov. from Turkey, D. japonica Kurina sp. nov. from Japan, D. peloponnensis Ševčík sp. nov. from Greece, D. svanetica Kurina sp. nov. from Caucasus and D. polyspina Kurina sp. nov. from the Russian Far East. New country records of the following species are presented: D. diutina Plassmann, 1996 (Turkey), D. flavicoxa Strobl, 1900 (Georgia), D. gilvipes (Haliday in Walker, 1856) (Georgia), D. kerkini Kurina & Ševčík, 2011 (Bulgaria), D. moravica Landrock, 1916 (Georgia), D. pannonica Lastovka & Ševčík 2006 (Georgia) and D. rameli Kurina & Ševčík, 2011 (Slovakia).
A new monotypic genus of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae), Medleria gen. nov., is described for Medleria caudata gen. et sp. nov. (type species) from the island of Socotra (Yemen). Habitus, male and female external and internal genital structures of the new species are illustrated and compared with similar taxa. Medleria caudata gen. et sp. nov. is probably endemic to Socotra where it is known to date from a small area of the Dixam mountain plateau only.

A new mesoserphid wasp from the Middle Jurassic of northeastern China (Hymenoptera, Proctotrupoidea)
(2017)
A new genus and species of Mesoserphidae (Hymenoptera), Juraserphus modicus gen. et sp. nov., is described based on a well-preserved fossil specimen from the Middle Jurassic Jiulongshan Formation of northeastern China. It is characterized by the following forewing features: the forking of Rs+M located approximately one-third of the distance between 1m-cu and 2r-rs, both 1cu-a and 2cu-a antefurcal; 1-M more than twice as long as 1m-cu and hind wing with cells r and rm closed. In addition, it has a short ovipositor, only extending slightly beyond the metasomal apex. Its new morphological characters broaden the diversity of Mesoserphidae in the Mesozoic and provide new insights into the evolution and relationships of Mesoserphidae.
Four new species of the genus Coecobrya, C. gejianbangi sp. nov., C. annulata sp. nov., C. ciliata sp. nov., and C. oculata sp. nov., are described from Guangxi caves as the representative of the genus in China. Coecobrya oculata sp. nov. of the boneti-group has 1+1 eyes and a serrate outer edge of the unguiculus. The other three species, devoid of eyes and with a tiny outer tooth on the unguiculus, are assigned here to the tenebricosa-group, assuming that the large tooth on the unguiculus is transformed into a tiny one in cave-obligate species. Clypeal chaetae in Entomobryoidea are systematically surveyed for the first time, and are found to be well diversified at species level. They have a potential taxonomical value in discriminating taxa of morphologically conserved groups.
The Iranian species of the genus Anomalon Panzer, 1804 (Hymenoptera: Ichneumonidae: Anomaloninae) are reviewed. Four species, Anomalon amseli (Hedwig, 1961), A. chinense (Kokujev, 1915), A. cruentatum (Geoffroy, 1785) and A. narinae Zardouei & Rakhshani sp. nov., are found to occur in Iran. The female of A. amseli is described for the first time. Anomalon chinense is a new record for Iran. A key to the known Anomalon species of Iran is provided.
A new fossil diatom species, Tertiarius minutulus sp. nov., is described from a sediment sequence DEEP-5045-1 of Lake Ohrid. The species is characterized by small valves (3.0–8.0 μm) with a round shape, a marginal area with radially arranged costae and a central uneven area with scattered areolae. Externally, the alveoli are occluded by cribra perforated by irregularly arranged pores. Internally, the alveoli are simple and areolae are occluded with domed cribra. The marginal fultoportulae are situated on costae close to the valve margin, located on every 5th or 7th thick internal costa. One to three fultoportulae are present on the valve face, each surrounded by two to three satellite pores. One rimoportula is present, positioned on a costa at the valve face / mantle junction. The species is compared with morphologically similar taxa and a detailed differential diagnosis is provided. Tertiarius minutulus sp. nov. is known only as a fossil taxon from Lake Ohrid, with a first occurrence during the early stages of lake basin development.
The classification of the largest subfamily of leafhoppers, Deltocephalinae, including 38 tribes, 923 genera, and 6683 valid species, is reviewed and revised. An updated phylogeny of the subfamily based on molecular (28S, Histone H3) and morphological data and an expanded taxon sample (37 taxa not included in previous analyses) is presented. Based on the results of these analyses and on the morphological examination of many representatives of the subfamily, the classification of the tribes and subtribes of Deltocephalinae is revised. Complete morphological descriptions, illustrations, lists of the included genera, and notes on their distribution, ecology, and important vector species are provided for the 38 recognized tribes and 18 subtribes. A dichotomous key to the tribes is provided. All names in the taxonomic treatments are hyperlinked to online resources for individual taxa which are supported by a comprehensive database for Deltocephalinae compiled using the taxonomic database software package 3I. The online functionality includes an interactive key to tribes and subtribes and advanced database searching options. Each taxon (subspecies through subfamily) has a unique taxon webpage providing nomenclatural information, lists of included taxa, an automated description (if available), images (if available), distributional information, bibliographic references and links to outside resources. Some observations and trends regarding the history of taxonomic descriptions in Deltocephalinae are reported. Four new tribes are described: Bahitini tribe nov. (25 genera), Bonsapeiini tribe nov. (21 genera), Phlepsiini tribe nov. (4 genera), and Vartini tribe nov. (7 genera). The circumscription and morphological characterization of Scaphoideini Oman, 1943 (61 genera) is substantially revised. Eleven new species are described: Acostemma stilleri sp. nov., Arrugada linnavuorii sp. nov., Drabescus zhangi sp. nov., Parabolopona webbi sp. nov., Goniagnathus emeljanovi sp. nov., Hecalus hamiltoni sp. nov., Scaphoideus omani sp. nov., Dwightla delongi sp. nov., Abimwa knighti sp. nov., Gannia viraktamathi sp. nov., and Doratulina dmitrievi sp. nov. Some family-group level taxonomic changes are made: Platymetopiini Haupt, 1929, Anoterostemmini Haupt, 1929, and Allygidiina Dmitriev, 2006 are synonymized with Athysanini Van Duzee, 1892, syn. nov.; Procepitini Dmitriev, 2002 is synonymized with Cicadulini Van Duzee, 1892, syn. nov.; Listrophorini Boulard, 1971 is synonymized with Chiasmini Distant, 1908, syn. nov.; Adamini Linnavuori & Al-Ne’amy, 1983, Dwightlini McKamey, 2003, and Ianeirini Linnavuori, 1978 are synonymized with Selenocephalini Fieber, 1872 syn.nov., and all three are now recognized as valid subtribes in their parent tribe. New placements of many genera to tribe and subtribe are made, and these are described in individual taxon treatments.
Two species of Tomoceridae were found near Dalat, southern Vietnam. Tomocerus ocreatus Denis, 1948 is redescribed based on a neotype specimen. Previous records of Tomocerus ocreatus in non-type localities are reevaluated. A new species Tomocerina annamitica sp. nov. is described. The new species is mainly characterized by its small body size, pointed tenent hair, compound dental spines and the absence of intermediate teeth on mucro.
The endophallic structure of the genus Laius is studied and discussed based on the examination of 19 species from Asia to the Indian Ocean. The structure contains two primary sclerites (named gonoporal piece and ligula), a secondary sclerite on the basal part of the gonoporal piece (named additional sclerite) in some species, and a membranous basal area closely covered with many spines (named spinous area). Five species groups are recognized based on the morphology of the endophallic sclerites. The sympatric species have different body sizes and quite distinguishable endophallic sclerites (= different species group), while the allopatric species have overlapping body sizes and similar endophallic sclerites (= same species group). Three new species are described and six previously known species are redescribed with endophallic sclerites, and the descriptions of endophallic sclerites of the remaining ten species are added. The larva of Laius rodriguesensis sp. nov. is also described. The genus
Nossibeus Evers, 1994 is synonymised with Laius Guérin-Méneville, 1830.
