AbstractThree shrubby, succulent, spiny Euphorbia (Euphorbiaceae) species from western Saudi Arabia are described and illustrated as new: Euphorbia madinahensis Fayed & D.Al-Zahrani, Euphorbia saudiarabica Fayed & D.Al-Zahrani and Euphorbia taifensis Fayed & D.Al-Zahrani. Diagnostic characters, descriptions and taxonomic comments on each are given, and they are compared with closely related species. The geographical distribution of the three new species is shown.

Pimpinella ibradiensis, an unusual new species found in the Toka Yayla (İbradı, Antalya) in southern Anatolia, is described and illustrated. Site conditions, synecology and conservation status of P. ibradiensis are considered. In light of the comparison with the other closely related four species, namely P. nephrophylla, P. flabellifolia, P. sintenisii and P. paucidentata, its similarity within the genus are discussed. P. ibradiensis is easly distinguished from its relatives by its white petals, presence of bracts and bracteoles, larger fruits (4–5.5 × 1–2 mm), and having serrulate basal leaves with 60–95 strongly cartilaginous teeth along margins. The geographical distribution of P. ibradiensis and closely related species are mapped and the identification key of those species is updated.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).

We describe a new species of Gomesa (Oncidiinae, Orchidaceae), Gomesa caatingana, with restricted distribution on caatinga inselbergs in Paraíba and Pernambuco States, Brazil. Morphological and karyological characters of the new species were compared with those of Gomesa flexuosa, which is morphologically the most closely related species. Differences in geographical distribution, habit, flower morphology and chromosome number support description of this new species.

Elaphoidella thailandensis sp. nov. and E. jaesornensis sp. nov., collected during an investigation of cave-dwelling copepod fauna in the northern part of Thailand, are described and figured herein. The new species were collected from pools filled by percolating water from the unsaturated zone of a karstic aquifer in Phitsanulok and Lampang Provinces, respectively. Elaphoidella thailandensis, from Tham Khun cave, is distinguished from its congeners by the two-segmented endopod of pediger 1, the absence of endopod on pediger 4, and the setal formula 4, 5, 6 for the distal exopodal segment of pedigers 2–4. Elaphoidella jaesornensis, from Tham Phar Ngam cave, is distinguished from its most closely related species, E. namnaoensis Brancelj, Watiroyram & Sanoamuang, 2010, by the armature formula of the endopod of pedigers 2–5. The geographical distribution and ecology of Harpacticoida from Thai caves is also presented.

Three new species of the genus Tylenchorhynchus Cobb, 1913 from Canada are named and described. Tylenchorhynchus irregularis n. sp. differs from all closely related species in the irregular width of the cuticular annulation, especially in the posterior half of the body. T. longus n. sp. is similar to T. superbus Allen, 1955 but differs from this species in relative tail length and annulation of the tail terminus. T. laminatus n. sp. resembles T. leptus Allen, 1955 but differs in the details of the lip region, spear length, and laminated annules.

A new species, Queskallion saetosumsp. nov., is described herein from Sichuan Province, China. It is diagnosed from a closely related species, Q. tangi Smetana, 2015. Color images and line drawings of the adult of the new species, as well as its genitalia are provided. In addition, a checklist of species, an updated key to species and a geographical distribution map of all known species in the genus Queskallion Smetana are included.

AbstractTwo new genera and three new species of feather mites (Astigmata, Pterolichoidea, Analgoidea) are described from two closely related species of cockatoos, Cacatua galerita (type host) and C. sulphurea (Psittaciformes, Cacatuidae): Astrolabelichus caudatus gen. nov., sp. nov. (Pterolichidae), Psittophagus lacunosus sp. nov. (Pterolichidae), and Cacatualges microdiscus gen. nov., sp. nov. (Xolalgidae). The presence of the same set of mite species on these two species of parrots points to a very close affinity of Cacatua sulphurea and C. galerita and gives additional support for the recent hypothesis of the conspecificity of these birds.

Two new species (Rhabdoblattella hainanensis sp. n. and Rhabdoblattella disparis sp. n.) from Hainan and Yunnan Provinces, China are described and illustrated, which extends the geographical distribution of Rhabdoblattella northward from Vietnam. Photographs and detailed morphological descriptions including the male genitalia of R. hainanensis sp. n. and R. disparis sp. n. are given. For comparison, the photos of habitus and male genitalia of a closely related species, R. annamensis (Hanitsch, 1927) are provided. A key to all species of Rhabdoblattella is provided.
