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.

A new fern species, Polystichum weimingii (sect. Metapolystichum, Dryopteridaceae), is described from southern Yunnan, China. The new species is morphologically most similar to P. discretum. Compared to P. discretum, P. weimingii has a smaller habit, lanate (linear and curly), brown rachis scales, and pinnules without obvious aristate spines on the margin. In contrast, P. discretum is larger, has linear, dark brown rachis scales, and has pinnules with obvious aristate spines on the margin. The new species also differs from P. discretum in spore morphology. Features of the new species in anatomy of lamina epidermis, spore morphology, geographical distribution, and ecology are given. The relationships with three other closely related species in Polystichum ser. Linearia are discussed.

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.

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.

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.

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.

Two new species of mites are described from Europe on the basis of all developmental stages: Cilliba cassideasimilis sp. nov. and C. rafalskii sp. nov. (Acari: Uropodina: Cillibidae). Both of these species have been misidentified in the past as the closely related species C. cassidea, but these three species can be distinguished using morphological characters. Data on their geographical distribution and some remarks about ecology of both species are presented and discussed. New records of mites of the genus Cilliba are given.

Several specimens from historical collections made in Yunnan (PR China) were found to be inconsistent with hithertoknown species of Japalura. Two species are described as new: Japalura brevicauda spec. nov. and Japalura yulongensisspec. nov. Diagnostic features for the new species are compiled and a key to closely related species is produced. The geographical distribution of these species is outlined and discussed.

Paraphlomis kuankuoshuiensis (Lamiaceae), a new species found in the limestone areas of northern Guizhou, China, is described and illustrated in this paper. Based on its tubular-campanulate calyx, this taxon should be a member of sect. Paraphlomis Prain. The new species resembles P. patentisetulosa C.Y. Wu & H. W. Li, P. hispida C.Y. Wu, and P. hirsutissima C.Y. Wu & H.W. Li, but differs from these three taxa in the following aspects: the stems are very short (<7 cm), with one or two short internodes, giving the impression of having a tuft of basal leaves; it has sparsely setose hairs on the outer surface of the calyces and short fruiting calyces. The florescence, fruit period, habitat, and the geographical distribution of P. kuankuoshuiensis are also quite different from the three closely related species.
