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.

The Central Asian spider genus Anemesia Pocock, 1895 is rediagnosed and revised. The genus was found to contain 14 species: ♂♀ A. andreevae sp. nov. (Uzbekistan, Tajikistan); ♂♀ A. birulai (Spassky, 1937) (Turkmenistan); ♂♀ A. castanea sp. nov.; ♂♀ A. incana Zonstein, 2001, ♂♀ A. infumata sp. nov.; ♂♀ A. infuscata sp. nov.; ♂♀ A. karatauvi (Andreeva, 1968) (all Tajikistan); ♂ A. koponeni Marusik, Zamani & Mirshamsi, 2014 (Iran); ♂♀ A. oxiana sp. nov.; ♂♀ A. pallida sp. nov.; ♂ A. parvula sp. nov. (all Tajikistan); ♂♀ A. pococki sp. nov. (Turkmenistan); ♂♀ A. sogdiana sp. nov. (Uzbekistan, Tajikistan) and ♂♀ A. tubifex (Pocock, 1889), the type species (Afghanistan, Turkmenistan). Nine species are newly described; others are redescribed from types and/or conspecific material. Males of A. tubifex and females of A. birulai, hitherto unknown, are described for the first time. Data on the variability, relationships, distribution, and ecology of all considered species are provided.

A new species complex, the eparmata complex, is established within the subgenus Phortica s. str., based on eight known and five new species, all of which are endemic to the Oriental Region: P. bipartita (Toda & Peng, 1992), P. eparmata (Okada, 1977), P. lanuginosa Chen & Toda, 2007, P. latipenis Chen & Gao, 2005, P. pangi Chen & Wen, 2005, P. setitabula Chen & Gao, 2005, P. unipetala Chen & Wen, 2005 and P. zeta Chen & Toda, 2007; P. jadete sp. nov., P. kava sp. nov., P. mengda sp. nov., P. wongding sp. nov. and P. yena sp. nov. A key to all species of this complex is provided. Barcoding sequences (mitochondrial COI gene) were obtained for 22 specimens of five known and the five abovementioned new species. The intra- and inter-specific pairwise K-2P (Kimura’s two-parameter) distances of COI were determined. Phylogenetic analysis was performed using Bayesian inference based on COI sequences, confirming the monophyletic status of the eparmata complex, which is distinct from the species complexes of magna, omega, variegata and another two ungrouped species.

Cochlostoma revised: the subgenus Lovcenia Zallot et al., 2015
(Caenogastropoda, Cochlostomatidae)
(2018)
Five species of the subgenus Lovcenia of Cochlostoma (Cochlostomatidae) are recognized, three of which are described as new to science: C. (L.) tropojanum sp. nov., C. (L.) jakschae sp. nov. and C. (L.) lanatum sp. nov. A lectotype is designated for C. (L.) erika (A.J. Wagner, 1906). The shell and the genital tracts are described for all species and the distributional data are summarized.

The concept of the jumping spider genus Pochytoides Berland & Millot, 1941 is reviewed, based on the examination of described and undescribed species. Pochytoides is elevated from the subgeneric to the generic rank and a short diagnosis and description of the genus are presented. Redescriptions or descriptions of all species are provided together with a key to the species. Two new combinations are proposed: Pochytoides perezi (Berland & Millot, 1941) comb. nov. and P. poissoni (Berland & Millot, 1941) comb. nov. (both from Pochyta). Pochyta remyi Berland & Millot, 1941 originally placed in the subgenus Pochytoides is excluded; new combination Thiratoscirtus remyi (Berland & Millot, 1941) comb. nov. is proposed for it (but its generic status is uncertain). Six new species are described: Pochytoides monticola sp. nov., P. obstipa sp. nov., P. lamottei sp. nov., P. patellaris sp. nov., P. securis sp. nov. and P. spiniger sp. nov. The genus has a West African distribution.

The South American genera of the Cimbicidae are reviewed. Five genera and nine species are recognized. Redescriptions of all genera and an identification key to all species are provided. All species are illustrated, including both sexes and aberrant specimens when relevant. The South American Cimbicidae are grouped in the subfamily Pachylostictinae, but there is substantial morphological divergence at the genus level. This and the isolated geographic and phylogenetic position relative to the other subfamilies of Cimbicidae indicates that the Pachylostictinae have evolved in isolation for a substantial amount of time. Host plant records are known for only one species, Pseudopachylosticta subflavata, which is mainly found in the Chacoan subregion. The distribution of the remaining species falls almost exclusively within the range of the Parana subregion forest provinces, a biome that has been much reduced by human activity in the past half millennium. It is likely that these rarely collected wasps are threatened by habitat degradation.

Four new species of Xiphocentron (Antillotrichia) Brauer, 1870 from the Atlantic forest are diagnosed, described and illustrated. All of them have a small mesal sclerite and a set of spines, differing in size, density and position, on the inner face of the inferior appendage. Moreover, tergum IX varies mostly in the shape of the posterior margin. Four species are described as new for science. Xiphocentron (Antillotrichia) copacabana sp. nov. is distinguished mainly by the projected basoventral margin of the inferior appendage, the spines are clustered in two regions and the quadrate posterior region of tergum IX. Xiphocentron (Antillotrichia) maracanan sp. nov is differentiated by the inferior appendage, with a strongly angled apical region of 90º. Xiphocentron (Antillotrichia) redentor sp. nov. differs by the inferior appendage, with a linear row of thick spines, and the tergum IX, with a posterior margin forming smoothly rounded lobes. Xiphocentron (Antillotrichia) tijuca sp. nov. is diagnosed by the subbasal region of the preanal appendage, which is markedly projected medially, and by the inferior appendage, which is thin subapically, enlarged apically and strongly bent dorsad.

The new genus Phasmomantella gen. nov. is created to accommodate the new species P. nuichuana gen. et sp. nov. described from five adult females from Núi Chúa National Park in southern Central Vietnam. A second species, Phasmomantella pallida (Roy, 2001) gen. et comb. nov., is transferred from Euchomenella where it was originally described based on a single male specimen from the Nha Trang region in the Khánh Hòa Province. Phasmomantella gen. nov. is placed in the tribe Euchomenellini of the subfamily Deroplatyinae. A comprehensive diagnosis and detailed descriptions are presented along with high-resolution photographs, measurements and a distribution map. The standardised measurements are illustrated and a new key is proposed for the tribe Euchomenellini. The unique biogeography and habitats of the collection site within Núi Chúa National Park are discussed in the light of possible endemism and importance for nature conservation.

Two Norwegian uristid amphipods, obligate associates of sea anemones, have for a long time been confused sub nomine Onisimus normani Sars, 1890. In reality this species only occurs in south Norway, while the north-Norwegian material belongs to O. turgidus (Sars, 1879), described from the Barents Sea and for a long time forgotten. This paper fully illustrates both species, gives a key, and provides data on their distribution and ecology.
