The holotype of Chitinotylenchus paragracilis (Micoletzky, 1922) is redescribed and illustrated. Chitinotylenchus is proposed as a synonym of Ditylenchus Filipjev, 1936 and C. paragracilis as Ditylenchus paragracilis (Micoletzky, 1922) new comb. The four other species in the genus Chitinotylenchus are considered species inquirendae.

A new species of wingless leaf litter weevil, Otibazo polyphemus sp. n., is described from Tam Dao, northern Vietnam. This is the fourth named species in the genus, with its three other species known only from Japan. Habitus and genitalia of the male holotype are illustrated and DNA barcoding data are provided. 

A new subgenus, Exallomyia, of the genus Wyeomyia is established for three species previously included in the subgenera Davismyia and Dendromyia, and in the genus and nominate subgenus Sabethes. The terminalia of the holotype males of the three species, the midlegs of the males of two species, and the larvae and pupae of two species are illustrated.

The male holotype of Trite lineata Simon, 1885 is redescribed and the palp is illustrated for the first time. The female is formally described. Three new species are diagnosed, described and illustrated: Trite caledoniensis sp. nov., T. guilberti sp. nov. and T. simoni sp. nov. Remarks on distribution and relationships of the genus are given.

A new species of the genus Eremohadena Ronkay, Varga and Fabian, Eremohadena afzalipouri Shirvani sp. nov., is described from southeastern Iran. Holotype and female paratype and genitalia of both sexes are illustrated for the new species. A checklist of Iranian species of Eremohadena including nine species and subspecies is provided.

The holotype of the Emperor Scorpion Pandinus imperator (C.L. Koch, 1841) was long believed to have been lost. In 2015, as scientists at the State Museum of Natural History in Stuttgart were digitizing its entomological collections, they rediscovered the specimen on which Koch had based his description of the scorpion in 1841.

Three species of Rhodacaroidea are reported from soil in Colombia. Desectophis anthuriumsetis n. sp. (Ologamasidae) and Multidentorhodacarus colombianus n. sp. (Rhodacaridae) are described from newly-collected material. Multidentorhodacarus triramulus (Karg, 1998) is redescribed from the holotype and adult females collected in this study. A key for the separation of females of the five recognis...

Two new butterfly species belonging to the genus Aphnaeus (Lycaenidae: Theclinae), A. mirabilis sp. n., A. nimbaensis sp. n. were found in the Nimba Mountains, Western Range, Liberia in February 2012. Both are illustrated and described in comparison with closely related species: A. flavescens Stempffer, 1954 and A. liberti Bouyer, 1996, respectively. Genitalia of the male holotype of A. nimbaen...

The morphology of adult instars of two oribatid mites of the genus Neoribates, N. pallidus Aoki, 1988 and N. alius Fujikawa, 2007, is analyzed. Comparisons were based on holotype and paratypes (for N. alius) and specimens identified by the original author (for N. pallidus). Both species were described from Japan. Neoribates alius is recognized as a junior subjective synonym of N. pallidus.

The aphid genus Asiphonipponaphisgen. n. from China is new to science. Asiphonipponaphis vasigallasp. n. causing galls on Distylium chinense from Hunan, China is described and illustrated. Holotype and paratypes are deposited in the National Zoological Museum of China, Institute of Zoology, Chinese Academy of Sciences, Beijing, China (NZMCAS) and Kogakkan University, Japan.
