Alphasida (Glabrasida) bounaceurensis sp. nov. is described from the Jbel Bou Naceur top, the most eastern summit of the Moroccan Middle Atlas range. It is compared to other morphologically and geographically related species. Type material of Alphasida (Glabrasida) lecerfi Koch, 1940 and its subspecies is studied. A lectotype is designated for Alphasida (Glabrasida) iblanensis Antoine, 1939. We propose here a new synonymy: Alphasida (Glabrasida) iblanensis Antoine, 1939 = Alphasida (Glabrasida) lecerfi ighrezranensis Koch, 1940.

Zadenos jani, Z. jozwiki, Z. kaweckii and Z. szatalowiczi are described as new species. Z. incostatus Koch, 1956 and Z. natalensis Koch, 1956, previously known only from female specimens, are redescribed. Lectotype for Zadenos mulsanti Koch, 1956 is designated, in order to fix the taxonomic status of this species. An updated checklist of all known Zadenos species is provided. This paper brings the total species number within the genus to 37.

Crististibes Koch, 1963 (type species: Planostibes binodosus Gebien, 1920) is revised and illustrated. The genus belongs to monophyletic stizopoid group which consists of endemic genera distributed in southern Africa. New species are described: Crististibes tuberculatus and C. ugabensis. Key for species determination is provided. The genus Crististibes consists of three species distributed in Namibia.

A new species of the endomychid subfamily Leiestinae, from Japan, Panamomus jaloszynskii sp. nov. is described, diagnosed and illustrated. A key to the known species of Panamomus is provided.

Lichenophanes vespertinus is described as a new species of Bostrichidae from Gambia. As a result this paper increase the number of know African representatives of Lichenophanes up to 21. An updated checklist of all species from Ethiopian Region is provided.

The genera of Tropiduchidae tribe Paricanini are discussed and their key to identification of the genera is given and key characters illustrated. The new genus Lukabales gen. nov. with a new species Lukabales ecarinatus sp. nov. is described based on specimens collected in montane areas of Cambodia and Thailand.

The family Tropiduchidae Stål in Madagascar according to distribution and relationships of genera is discussed. A key to all tropiduchid genera as well as the checklist of species known from Madagascar are proposed. Two new genera of the tribe Elicini Melichar, Bolitropis gen. nov. with 6 new species (B. irwini sp. nov., B. montanus sp. nov., B. olsufievi sp. nov., B. imperator sp. nov., B. strobilus sp. nov., B. synavei sp. nov.) and Bambomada gen. nov. with a single new species B. flava sp. nov. are described.

Five prostigmatic mite species from the family Cunaxidae are recorded in Hungary. Four of them: Cunaxa polita Kazmierski et Ripka sp. nov., Cunaxa subita Ripka et Laniecka sp. nov., Cunaxa minuta Laniecka et Kazmierski sp. nov. and Cunaxoides ornatus Kazmierski et Laniecka sp. nov. are described as new to science, whereas Cunaxoides kielczewskii Michocka, 1982 is discussed and figured. Leg's organotaxy for C. kielczewskii is given for the first time.

Three species of fossil smaridid mites (Parasitengona, Smarididae) are described based on postlarval forms. Fessonia wunderlichi sp. nov., Fessonia grabenhorsti sp. nov. and Fessonia groehni sp. nov. were discovered in Eocene (ca. 44–50 Ma) Baltic amber and the former two also in the probably younger Oligocene (ca. 23–25 Ma) Bitterfeld amber. Although Smarididae has been reported from Baltic (and other) Cenozoic amber localities, these are the first species from this group to be formally described. Fessonia wunderlichi sp. nov. and Fessonia grabenhorsti sp. nov. are also the first named mites from Bitterfeld amber, and at the same time the first examples of mite species common to both the Baltic and Bitterfeld deposits. Fessonia groehni sp. nov. is known from a single specimen originating from the Baltic deposit. Although the thickened hindlimbs seen in Fessonia wunderlichi sp. nov. resemble the modern smaridid genus Kraussiana Southcott, 1961, the structure of the crista metopica implies another extant genus — Fessonia von Heyden, 1826 — which we redefine here to accommodate the morphology of the amber species. An outline of previous findings of terrestrial Parasitengona in amber is also provided.

A new stygobitic cyclopoid species, Mesocyclops sondoongensis sp. nov. is described from caves in central Vietnam. This is the first cave-dwelling representative of Mesocyclops in SE Asia. Conspicuous features of the new species, such as the narrow lateral arms of the seminal receptacle and the presence of medial spine on leg 1 basipodite, are only shared with the rarus-group in the Paleotropics, but common among the Neotropical representatives. Surface ornamentation of the labrum is similar to that in the Middle American reidae-clade, a basal lineage in Mesocyclops. The basal relationships within Mesocyclops are re-examined herein. Strict consensus tree shows that: i. M. sondoongensis and the rarus-group constitute a clade, which is the sister to all Mesocyclops exclusive of the reidae-group; ii. the Neotropical species and M. edax (North and Middle America) constitute a clade, which is the sister to all Mesocyclops lacking medial spine on leg 1 basipodite and distributed mainly in the Paleotropics. Branching sequence of the trees might be congruent with: i. origin of the genus in Northern Tropical Gondwana, ii. origin of the clade (M. sondoongensis, rarus-group) in India-Madagascar, and dispersal from India to SE Asia in the Eocene when India collided with Asia; iii. New World-Old World vicariance during separation of northern South America from Africa in the Cretaceous.

Three new species belonging to the subgenus Cyrtocoelioxys Mitchell, 1973 of Coelioxys Latreille, 1809, Coelioxys (Cyrtocoelioxys) lactea sp. nov. from São Paulo State, Brazil and C. (C.) acanthosara sp. nov., and C. (C.) jordiana sp. nov. both from Nayarit and Oaxaca States, Mexico, are described and illustrated. An updated checklist of the 73 species of the subgenus Cyrtocoelioxys of Coelioxys is also provided. Two species are placed in synonymy: Coelioxys (C.) sanguinea Friese, 1921 syn. nov. of Coelioxys (C.) costaricensis Cockerell, 1914 (nec Friese, 1916) and Coelioxys (C.) gigantea Friese, 1921 syn. nov. of Coelioxys (C.) zonula Smith, 1854. The subspecies Coelioxys (C.) unidentata obscuriventris Friese, 1921 is raised to species level, as C. (C.) obscuriventris stat. nov. For the following three species the new subgeneric placement is proposed: C. (C.) ignava Smith, 1879 = C. (Glyptocoelioxys) ignava; C. (G.) leopoldensis Friese, 1921 = C. (Cyrtocoelioxys) leopoldensis and C. (G.) triangula Friese, 1906 = C. (C.) triangula. Five species previously considered as incertae sedis are assigned to Coelioxys (Cyrtocoelioxys): C. (C.) ambrosettii Holmberg, 1918; C. (C.) hirtiventris Popov, 1946; C. (C.) paranensis Schrottky, 1920; C. (C.) spatulata Friese, 1921 and C. (C.) tabayensis Schrottky, 1920. A key to the Mexican species of the subgenus Cyrtocoelioxys is provided.
