The following are notes on the taxonomies and synonymies, and on the distributions in Canada, of the Nearctic species of leafhoppers of the genus Oncopsis Burmeister. Twenty-one species referable to this genus have been described from the Nearctic region. Seventeen were listed as valid species by Oman (1949), under Oncopsis, Macropsis, and Zinneca. One is probably not a Nearctic species. In the present paper 14 names are considered to be synonyms. This reduces the number of Nearctic species to seven, including one new species described below. Wagner (1949) discussed six species found in Germany. Of these, two were new and the remaining four had been described under a total of 14 names.

AbstractFour species have been described in the apterus-group of the staphylinid genus Tachinus Gravenhorst. One of these, tundrae Poppius, is regarded as a synonym of brevipennis Sahlberg. Tachinus arcticus (Motschulsky) is recognized as a valid species, although earlier works have considered it a synonym of apterus. Tachinus brevipennis is recorded from the Nearctic Region for the first time. A neotype is designated for arcticus and lectotypes are designated for brevipennis and tundrae. Tachinus instabilis Mäklin is transferred to the apterus-group from the fimbriatus-group and recorded for the first time from Siberia. One new species, T. glacialis, is described from Siberia.A key for identification of the species of the group and a description of the group characters are included. Each of the five species is described and the major diagnostic characters illustrated with scanning electron photomicrographs. A map is included to show the distribution of the species.

AbstractThe Nearctic Idiocerini exclusive of the fauna of the Sonoran subregion are reviewed. The 68 recognized species are assigned to three genera: Idiocerus Lewis, Rhytidodus Fieber, and Balcanocerus Maldonado-Capriles. Three subgenera of Idiocerus are recognized, including I. (Liocratus) Dub. and I. (Populicerus) Dlab. (n. stat). Sahlbergotettix Zvk., 1953, Viridicerus Dlab., 1974, Tremulicerus Dlab., 1974, and Acericerus Dlab., 1974 are synonymized with Idiocerus Lewis, 1834.Sixteen new species of Idiocerus are described: aureus, carolina, cedrus, freytagi, gillettei, immaculatus, inebrius, iodes, lucidae, midas, pericallis, taiga, unicolor, vanduzeei, venosus, and xanthiops. I. varions n. n. is created for varias DeLong & Hershberger, 1947 (nec Germar, 1818). I. lunaris Ball (n. stat.), I. obsoletus (Wlk.) (n. stat.), and I. raphus Freytag (n. stat.) are recognized as valid species for the first time. Twelve other species are removed from synonymy. I. verrucosus Ball is placed as a subspecies of I. musteus Ball (n. stat.). Five new synonymies are created: alnirubratus Bliven, 1955 = I. couleanus Ball & Pkr., 1946; nigrens DeL. & Cld., 1937 = I. distinctus Gill & Bak., 1895; duzeei Prov., 1890 and vagus Ball, 1902 = obsoletus Walker, 1851; and apertus DeL & Hbr., 1947 = I. verticis (Say), 1831.Additional characters of the male antennae, male abdominal apodemes, and female ovipositor are described and illustrated. The phylogeny and hosts of the members of Idiocerus are discussed. Keys are provided to the genera of the Nearctic Idiocerini, and to the species of Idiocerus of the Nearctic region, exclusive of the Sonoran subregion, for both sexes.

During a survey, 12 known and one new species of Ditylenchus Filipjev, 1936 were collected from southern provinces of Iran during 2013–2017. Ditylenchus paraparvus n. sp. is characterised by a short body length (441–543 µm), lateral field with four lines, delicate and short stylet (6–7.5 µm) with small rounded or posteriorly sloping knobs, pyriform and offset basal pharyngeal bulb, V = 67.7–76.4, short post-vulval uterine sac less than one vulval body width long, small spicules (12.5–15 µm) and almost cylindrical tail (71–90 µm) with rounded end. Morphometric data of studied species are presented and intraspecific variation of their morphometrics and morphological characters is discussed. The list of the world Ditylenchus species is updated, and a dichotomous identification key and an updated tabular compendium for 63 valid species is provided.

The Afrotropical species of Pachyanthidium Friese are revised. Sixteen species are recognized in four subgenera. One new species, Pachyanthidium (Trichanthidium) anoplos sp. n. is described; and one species, Pachyanthidium (Trichanthidium) cucullatum (Friese), is reinstated as a valid species. Four new synonymy are proposed: Pachyanthidium minutulum Pasteels =Pachyanthidium (Trichanthidiodes) semiluteum Pasteels syn. n.; Anthidium africanum Smith = P. (P.) bicolor (Lepeletier) syn. n.; Pachyanthidium cordatum swellemdamense Mavromoustakis = Pachyanthidium (P.) cordatum (Smith) syn. n. and Anthidium cordatum var. salamense Friese 1931 = Pachyanthidium (P.) salamense (Friese 1915) syn. n. Identification keys for the Afrotropical species are given.

Examination of material representing the 24 previously named species and subspecies of Austrophilopterus resulted in recognition of only 6 of these as valid species and 18 as synonymies, including a previously established junior synonym and 17 new synonymies. These 6 species are redescribed and illustrated. One new species, A. thysi, is described from the type host Selenidera gouldii (Natterer).

More than one-fourth of the spiders examined for this revision were collected since the neotropical genusScoloderuswas revised in 1976. Thirteen names have been proposed for what appear to be five valid species (Scoloderus cordatus, S. gibber, S. nigriceps, S. tuberculifer,andS. ackerlyi). These species are distinguished by the presence or absence of abdominal humps on the female, the shape of the median apophysis of the male palpus, and the shape of the scape of the female epigynum. Abdominal coloration and pattern are highly variable and unreliable for identification. One new species,Scoloderus ackerlyi, is described on the basis of a single, unique female from Belize.

The Indo-Pacific peristediid genus Satyrichthys Kaup, 1873 was first diagnosed as having a broad head with mesethmoid, postocular, parietal and preopercular spines. Later, most ichthyologists characterized Satyrichthys by its toothless jaws and strong preopercular spine. Kawai (2008) divided Satyrichthys into two genera, Satyrichthys and Scalicus, on the basis of a phylogenetic hypothesis, and redefined Satyrichthys. Seven species of Satyrichthys are recognized here, including one new species: S. clavilapis, S. laticeps, S. longiceps, S. milleri sp. nov., S. moluccensis, S. rieffeli and S. welchi. The new species is distinguished from its congeners in having equilateral-triangular rostral projections, 4 lip and 4 chin barbels, and no anterior directed spines on the upper lateral row of the caudal peduncle. Satyrichthys laticeps, previously treated as a junior synonym of S. moluccensis, is regarded as a valid species. The following new synonyms are noted: S. adeni, S. halyi and S. magnus are all junior synonyms of S. laticeps; S. isokawae is a junior synonym of S. moluccensis; and S. lingi is a junior synonym of S. welchi. In addition, a neotype is designated for S. moluccensis.

Herein one new species of Amazhomidia Cipola & Bellini from Brazilian Amazon is described and illustrated: A. thaisae sp. nov., plus one specimen no nominal due to lack of material for formal descriptionend point.  Acanthocyrtus guianiensis Womersley is redescribed and transferred to Amazhomidia by presence of prelabral chaetae bifurcated, macrochaetotaxy pattern, manubrium laterally with long distal mac finely ciliate and dens ventrally unscaled. Acanthocyrtus croceus Womersley is confirmed as a junior synonymy of A. guianiensis. The juvenile description of Amazhomidia ducke is provided, and changes in chaetotaxy nomenclature are made based on them. Acanthocyrtus lineatus Womersley is redescribed based on type material and new diagnostic characters are revealed. Identification keys for both genera and a comparison for Entomobryinae genera with dental spines are provided. Amazhomidia has now three and Acanthocyrtus Handschin six valid species.
