Tigronehoides andrassyi sp. nov. from Baltic coastal dune in Poland is described and illustrated. New species is characterized by medium body length (females 2.25–2.65 mm, males 2.27–2.72 mm), spacious buccal cavity (females 57.1-60.0 × 49.3-53.9 µm, males 49.5-52.4 × 41.2-43.3 µm), relatively high position of teeth apices (females 29.2–33.6%, males 39.9–42.5% ), longitudinal vulva with clearly separated sclerotizations, short and evenly tapered tail with cone-shaped posterior part.

A new species of mites of the family Veigaiidae (Acari, Gamasida) from the USA (Oregon, Mary's Peak) is described and figured.

Corrections and additions are provided to the checklist of nominal taxa of terrestrial Parasitengona mites published by Mąkol and Wohltmann (2012).

The morphology of juvenile stages and ontogeny of Scheloribates holsaticus (Weigmann, 1969), S. initialis (Berlese, 1908), and S. pallidulus (C. L. Koch, 1841) were investigated. The juveniles of these species have excentrosclerites at similar gastronotal setae (c₂, la, lp, and h₁ in larva, and C₂, la, lp, h-series, and P₁ in nymphs), and solenidion ω;₁ on tarsus I strongly curved outwards, which are typical of Scheloribatidae, but they differ by body size and the shape of most gastronotal setae. The successive juvenile stages of S. holsaticus are the largest, while those of S. pallidulus are the smallest. The former species has most gastronotal setae barbed, while S. initialis and S. pallidulus have them smooth. The latter species has these setae thinner and more curved than other species, and pliable in distal parts. The adult of all these species have notogastral sacculi, but S. holsaticus has 13 pairs of notogastral setae, including pairs C₂ and d-series, while other species have 10 pairs of setae, including pair C₂.

The present study is based on material collected during a two-month RussianEthiopian expedition in October and November 2011. An annotated checklist of identified oribatid mite taxa is presented. Two new oribatid mites of the family Oppiidae, Separatoppia concava, sp. nov. and Ramusella (Rectoppia) ginchiensis sp. nov., are described from moss of Cholomu forest (Southern Ethiopia). An identification key to all known species of Separatoppia is given. Eighteen species, 11 genera and two families are recorded for the first time from Ethiopia. The genus Furcoribula and species Trhypochthonius tectorum and Furcoribula furcillata are recorded for the first time from the Ethiopian region.

A new extraordinary monotypic genus of Ricaniidae is described from Mahé Island (The Seychelles archipelago) with a new species Mahecania trinigromaculata gen. et sp. nov. Photographs, drawings and SEM images are presented. Discussion is provided on unique and rare characters presented for this genus.

Two new species of Sogana Matsumura, 1914: S. condaoana sp. nov. and S. cucphuongana sp. nov., both from Vietnam are described and illustrated. The species are compared with S. longiceps Fennah, 1978. A key to the species from Vietnam and a distribution map are provided. The genus now contains 10 species. The records of S. longiceps from China are considered as erroneous.

As a result of biodiversity research on Socotra Island, a new species of the genus Deretus Gahan, 1900 is described — D. hajeki sp. nov. The new species is figured, compared with its relatives and keyed.

The taxonomic and distributional data concerning the representatives of the Quadrideres interioris species-group were revised. Lectotypes for Q. interioris (Gebien, 1911), Q. lesnei Koch, 1956 and Q. volcanicus Koch, 1956 were designated. Q. kaszabi sp. nov. and Q. rex sp. nov. were described. An identification key is provided to all known species of the Q. interioris species-group. This paper brings the total species number within the genus Quadrideres to 18.

Humerus medogicus gen. nov. and sp. nov. from Medog of Xizang, China is described and illustrated. Placement of this genus within the subfamily Lycoperdininae is discussed. Key to the genera of Amphisternus-group of Lycoperdininae is provided based on the key of Tomaszewska (2005).

This paper reviews five species of Limbobotys Munroe et Mutuura that occur in the Oriental Region. One species, L. acanthi sp. nov., is described as new. Diagnoses are provided for all previously described species. The adult and genitalia of the new species are figured, and a key to all the known species is provided.

During long-term field studies on division of space between the territorial ant species Lasius fuliginosus (Latr.) and Formica polyctena, Först. in southern Finland a severe decrease in the abundance of subordinate ant species was observed within L. fuliginosus territory. As part of this study we analyze the extent of changes in subordinate ant species assemblage in the light of already documented cases of L. fuliginosus predation on colonies of subordinate ants. The results showed that L. fuliginosus had a much stronger negative impact on co-occurring subordinate species, than the neighbouring rival F. polyctena. The hypothesis of hunger-induced myrmecophagy in this species is put forward, and is discussed as a possible competitive mechanism by which L. fuliginosus could shape ant assemblages within its territories.

The genus Doryctinus Roman is recorded for the first time in the fauna of the Old World and African continent. A new species D. africanus sp. nov. from Congo reared from the beetle larvae of the families Lyctidae and Scolytidae is described and illustrated. The discussion about composition of this genus and its synonyms is presented. A key to the World Doryctinus species is provided.

Descriptions of seven new species of the genus Dinotrema Foerster with widely sculptured propodeum are suggested: D. agaricophagum sp. nov. (Denmark and Ireland), D. curtisetum sp. nov. (Denmark), D. deprane sp. nov. (Denmark), D. haeselbarthi sp. nov. (Denmark and Italy), D. lobatum sp. nov. (Denmark, Finland and Portugal), D. paludellae sp. nov. (Denmark) and D. setaceum sp. nov. (Germany). The comparisons of the these new species with the most similar Palaearctic Dinotrema taxa are given.

A new species of the genus Dicranomyia Stephens, 1829 (Diptera: Limoniidae) from Baltic amber (Eocene) is described. The characteristic feature distinguishing a new species, D. gorskii sp. nov. is the presence of the surprisingly strong and elongate spine on rostral prolongation of ventral gonostylus. The morphological features of the new species are briefly discussed. New replacement name Dicranomyia alexandri nom. nov. for Dicranomyia flagellata (Alexander, 1931) is proposed to avoid with Dicranomyia flagellata Edwards, 1928.

Morphometric and karyological variations were analysed within the Moorish gecko Tarentola mauritanica sensu lato from Tunisia, and compared with already published data. The results show high levels of interspecific variability, indicative of the existence of two distinct lineages: the larger one T. fascicularis, widespread in the south, nearly identical to specimens from Libya and Egypt and the other one, T. m. mauritanica, confined to the northern and central regions, belonging to the common “European” and “North African” morphotype. The observed morphological variation appears to be related to microevolutionary events (phylogenetic variation) derived from a speciation event between the two taxa. We observed that these two lineages also differed in karyotype, such as the shape of some chromosomes and position of NORs. This study highlights the importance of Tunisia as a transition area between eastern and western lineages of Moorish gecko. However, additional genetic studies seem to be essential to infer evolutionary relationships among T. mauritanica populations' across North Africa.
