Some 2,000 Ptiliidae collected in the North and South Islands of New Zealand in 1983/1984 by Peter Hammond of the Natural History Museum, London, are determined to 34 species, four of which are new to the country. As there are very few previous records, most from the Auckland district of North Island, the Hammond collection provides much new distributional data. The three new species: Nellosana insperatus sp. n., Notoptenidium flavum sp. n., and Notoptenidium johnsoni sp. n., are described and figured; the genus Ptiliodes is moved from Acrotrichinae to Ptiliinae, and Ptenidium formicetorum Kraatz recorded as a new introduction. Information is provided to aid separation of the new species from those previously recorded.

The study is based on new material from the collections of the Naturalis Biodiversity Centre in Leiden (RNHM) and the Hungarian Natural History Museum (HNHM) and addresses issues in two genera: Epeus Peckham & Peckham, 1886 and Ptocasius Simon, 1885 from Thailand. Both genera are of Asian/Indomalayan origin, the latter with a diversity hotspot in the subtropical valleys of the Himalayas. Based on morphological data, we propose three new species of Epeus (Epeus daiqini sp. nov. (♂♀), Epeus pallidus sp. nov. (♀), Epeus szirakii sp. nov. (♀)) and two new species of Ptacasius (Ptocasius metzneri sp. nov. (♂♀) and Ptocasius sakaerat sp. nov. (♀)). Additionally, we redescribed E. tener (Simon, 1877) and added photographs of morphological characters. The genus Ptocasius is redefined due to the inclusion of 37 species, previously included in Yaginumaella Prószyński, 1979. Relationships and distribution of both genera are discussed in reference to molecular, morphological and distributional data, published by other authors in recent years.

This paper presents descriptions of three new species of Ephemeroptera from Illinois, all belonging to the genus Ephemerella. These are forms segregated from material in the Illinois Natural History Survey collection; the types are deposited in that collection. Two of these species are closely related to the genotype, E. excrucians Walsh, and it was thought for some time that one or the other of them would prove to be that species. Study of the lectotype of excrucians showed, however, that both of these species are recognizably distinct from excrucians.

Aphid specimens belonging to the genus Aphis (Hemiptera, Aphididae, Aphidinae) collected on species of Baccharis (Asteraceae) in localities of Argentina and Chile, preserved in the Natural History Museum in London and in the Universidad de León collections, have been studied. They belong to six species: Aphis craccivora, Aphis gossypii and Aphis spiraecola, which are widely-distributed and polyphagous, and the new species: Aphis ingeborgae Nieto Nafría and Brown sp. n., Aphis conspicua Nieto Nafría and Mier Durante sp. n. and Aphis fuentesi Nieto Nafría and Ortego sp. n. which are here described from apterous and alate viviparous females, and also from oviparous females and males in the case of Aphis fuentesi. These six species plus the native and monophagous A. coridifoliae are those known in southern South America living on plants of Baccharis. Diagnostic features of new species and an identification key for apterous viviparous females of these seven species are presented.

Representatives of the Southeast Asian pholcid spider genus Uthina Simon, 1893 have been thought to be very homogeneous in their ecology and morphology. The 14 previously known species all inhabit near-ground microhabitats and cave entrances, and range from pale to dark brown in colour. Even their genitalia are partly very similar, with some species pairs being barely distinguishable based on morphological characters. Here we describe three new species from Bali, Java and Sulawesi that represent three further microhabitats and demonstrate considerable ecological and morphological diversity within the genus: U. maya, sp. nov. from Bali is a large dark species on tree trunks; U. hylobatea, sp. nov. from Bali and eastern Java is a pale leaf-dwelling species that exhibits colour dimorphism; and U. mimpi, sp. nov. is a pale troglomorphic species collected in the aphotic zones of two South Sulawesi caves. In addition, we present new data for five previously described species, including ultrastructure, natural history, new records, taxonomic notes and a description of the previously unknown female of Uthina khaosokensis Yao, Li & Jäger, 2014. Molecular data suggest that all previously described species are very closely related to each other (constituting the monophyletic luzonica-group), and that the three new species represent separate clades within the genus. However, the basal trichotomy could not be resolved: U. maya + (U. hylobatea + U. mimpi) + luzonica-group.

The branchial-attaching cymothoid genus, Elthusa Schioedte & Meinert, 1884 is a genus with a worldwide distribution of 36 species, including the three species described here. Elthusaraynaudii (Milne Edwards, 1840) is the only species that has been described from southern Africa. All South African material held at the National Museum of Natural History, Paris, France (MNHN) and the Iziko South African Museum, Cape Town (SAMC) identified as, or appearing to belong to, Elthusa was examined. Four species were identified, Elthusaraynaudii and three species that proved to be undescribed. Elthusaxenasp. n. can be distinguished by an evenly rounded pereonite 1 anterior margin, a roughly rectangular pleotelson, and narrowly rounded uropod apices that extend to more than half the length of the pleotelson. Elthusaacutinasasp. n. is identified by the produced and narrowly rounded cephalon anterior margin, acute uropods that are shorter than half the length of the pleotelson, and pereonite 1 anterior margin with medial projection. Elthusarotundasp. n. is characterised by the round body shape, broadly rounded uropod apices, and protrusions on the proximal and lateral margins of the merus and carpus of pereopod 7. A key to the South African Elthusa species is provided, together with a table summarising the hosts and localities of the 33 previously known species of Elthusa.

Pseudoscorpions inhabiting mature Quercus pyrenaica Willd. trees have been surveyed using hollow emergence traps and window traps in Salamanca, Spain. Three new species are described: Neobisium (N.) hispanicum Zaragoza & Hernández-Corral, n. sp., Rhacochelifer gaeli Zaragoza & Hernández-Corral, n. sp. and Rhacochelifer nonidezi Zaragoza & Hernández-Corral, n. sp. The genera Amblyolpium Simon, 1898 and Beierochelifer Mahnert, 1977 and the species Amblyolpium dollfusi Simon, 1898 and Beierochelifer peloponnesiacus (Beier, 1929) are new records for the Iberian Peninsula. Beierochelifer peloponnesiacus jonicus (Beier, 1932) is shown to be a junior subjective synonym of B. peloponnesiacus n. syn. New regional records of five other species belonging to the families Cheliferidae, Chernetidae and Withiidae are given. Keys are given for the species of the genera Pseudorhacochelifer Beier, 1976 and Rhacochelifer Beier, 1932 with elongated keels on posterolateral corners of carapace and anterior tergites in males, and for the Rhacochelifer species of the Iberian Peninsula. Complementary data to the description of the female syntypes from Caravaca (Murcia, mainland Spain) and males from the Canary Islands of Rhacochelifer pinicola (Nonídez, 1917) are given. Brief redescriptions of the female of Neobisium (N.) maroccanum Beier, 1930 and the male of Rhacochelifer euboicus Mahnert, 1977 are provided. The previous record of R. disjunctus from Slovakia is shown to be an error for R. euboicus. New data on the distribution and habitats of species of Cheliferidae, Chernetidae and Withiidae are given.

The Lecithoceridae of southern Africa are reviewed, based on material preserved in the Ditsong National Museum of Natural History, Pretoria, Republic of South Africa. A total of 22 species are recognized including three new species: Idiopteryx jansei sp. nov., Lecithocera minyodes sp. nov. and Protolychnis natalensis sp. nov. Isotypa Janse, 1954 syn. nov. is synonymized with Idiopteryx Walsingham, 1891 and Homaloxestis lophophora Janse, 1954 stat. rev. is raised to species rank, separating it from H. cholopis Meyrick, 1906. In addition, Lecithocera ochrometra Meyrick, 1933 is transferred to Torodora Meyrick, 1894 as T. ochrometra (Meyrick, 1933) comb. nov., Lecithocera officialis Meyrick, 1911 is excluded from Lecithocera Herrich-Schäffer, 1853, and Dragmatucha proaula (Meyrick, 1908) is newly reported from Kenya. It is revealed that the male genital figure for Homaloxestis cholopis (Meyrick, 1906) by Janse (1954) was erroneously illustrated, based on a different species which is probably undescribed. Another miss-placed figure of the genitalia by Janse (1954) was also found for Lecithocera aenicta Janse, 1954. Diagnosis, descriptions (only for the new species), depositories of types, and distribution data of all the known species are provided. Images of adults, male and/or female genitalia, and the venation of a few species are illustrated.
