Ochyrocera brumadinho n. sp. is described from Brumadinho, state of Minas Gerais, Brazil. This species has morphological affinities with males of O. ibitipoca Baptista, González & Tourinho, 2008, in having a cymbial apophysis of the palp enlarged subdistally, and this feature may be a putative synapomorphy that groups these species. It was collected inside caves in the Iron Quadrangle region and compared to Ochyrocera ibitipoca, which also inhabits caves in another region of the same state. Although both species were found in this type of habitat, neither present troglomorphic features.

Literature-based species lists for arachnids, excluding spiders and mites, found in the Republic of the Sudan are provided. We summarize records, references, and localities for 17 scorpions (Scorpiones), one harvestman (Opiliones), nine pseudoscorpions (Pseudoscorpiones), 21 camel spiders (Solifugae) and one whip spider (Amblypygi). There are no published records of palpigrades (Palpigradi), whip scorpions (Thelyphonida), schizomids (Schizomida) or ricinuleids (Ricinulei), although at least whip scorpions and ricinuleids would not be expected in East Africa based on their current distribution. Key literature for mites and ticks (Acari) is also mentioned. In general, the Sudanese arachnid fauna has not been documented in detail. Many more species, particularly among the harvestmen and pseudoscorpions, are to be expected, and we offer the data gathered here as a baseline for future work.

A new species, Dysdera galinae n. sp. is described from Antalya, Turkey. Its relationship to, and differences from, D. argaeica Nosek, 1905 are discussed. New localities of D. argaeica and Harpactea alanyana Özkütük, Elverici, Marusik & Kunt, 2015 are provided. The female of Harpactea terveli Lazarov, 2009 is described from the type locality, and the species identity, synonymy, and distribution are discussed. H. erseni Kunt, Özkütük & Kaya, 2010 is regarded as junior synonym of H. terveli, n. syn.

Cyrtarachne nagasakiensis Strand, 1918 (Araneidae) is newly recorded from India on the basis of a specimen collected from Assam. A species description is provided, with figures of the habitus and internal genitalia.

A new species of the genus Callobius is described from Amami-Ōshima Island, southwestern Japan, under the name of Callobius amamiensis n. sp., and the differences from the related species, C. yakushimensis Okumura, 2010 are shown. The male palp of the new species is characterized by having the short mesal process in the tibia. In the female specimen, the lateral lobes of the epigyne are situated distant from each other, hence the width of epigyne is almost twice the length. In addition, the mitochondrial cytochrome oxidase subunit I (mt-COI) partial sequences of the new species have been analyzed and documented for future use.

Four new Malagasy species of Entypesa Simon, 1902, E. andohahela sp. nov. (♂♀), E. enakara sp. nov. (♂), E. fisheri sp. nov. (♀), and E. rastellata sp. nov. (♂), are diagnosed and described from specimens deposited in the Field Museum of Natural History (Chicago, USA). All of them are clearly distinguishable from the known Madagascan congeners E. nebulosa Simon, 1902 and E. annulipes (Strand, 1907a), in details of colouration and structure of the eye group and spinnerets. In three of the four new species the males are known; they differ from males of the only South African congener, E. schoutedeni Benoit, 1965, in structure of the palpal tibia, configuration of the embolus, and the shape and armament of leg I. Data on the features of the hitherto known members of Entypesa are also provided.

A new species of the spider genus Tenedos O. Pickard-Cambridge, 1897 (Zodariidae: Storeninae), Tenedos jocquei n. sp., is described from the Colombian Andes, based on males and females. A map with this new and previously published records of the genus from Colombia is presented.

The webs of hahniid spiders are poorly known. Those of Neoantistea riparia (Keyserling, 1887) all included sheets near the surface of the ground, but were more complex and variable than the simple sheets mentioned in previous accounts. Additional components included: sparse tangles of variable size above the sheet; lines below the sheet; small, dense tangles near some edges of the sheet; and a temporary feeding chamber below the sheet built near a recently captured prey. Webs were close to the surface of damp ground and, as a result, spent long periods coated with droplets of water. These droplets may aid in prey capture, as water accumulated on struggling prey and may have hindered their escape. In contrast, droplets seldom adhered to the spiders.

A type species of the genus Steriphopus O. Pickard-Cambridge, 1873 is redescribed based on the topotype specimens from Sri Lanka. Endogyne and details of the male palp are described in details for the first time. The genus belongs to Chediminae and currently encompasses four species distributed from the Seychelles to Burma. Relationships of the genus is briefly discussed.

A new species of pseudoscorpion, Neobisium (Ommatoblothrus) achaemenidum n. sp. is described from a karst cave of western Georgia. Illustrations of diagnostic characters are provided to facilitate taxon recognition.
