More than one-fourth of the spiders examined for this revision were collected since the neotropical genusScoloderuswas revised in 1976. Thirteen names have been proposed for what appear to be five valid species (Scoloderus cordatus, S. gibber, S. nigriceps, S. tuberculifer,andS. ackerlyi). These species are distinguished by the presence or absence of abdominal humps on the female, the shape of the median apophysis of the male palpus, and the shape of the scape of the female epigynum. Abdominal coloration and pattern are highly variable and unreliable for identification. One new species,Scoloderus ackerlyi, is described on the basis of a single, unique female from Belize.

During a survey, 12 known and one new species of Ditylenchus Filipjev, 1936 were collected from southern provinces of Iran during 2013–2017. Ditylenchus paraparvus n. sp. is characterised by a short body length (441–543 µm), lateral field with four lines, delicate and short stylet (6–7.5 µm) with small rounded or posteriorly sloping knobs, pyriform and offset basal pharyngeal bulb, V = 67.7–76.4, short post-vulval uterine sac less than one vulval body width long, small spicules (12.5–15 µm) and almost cylindrical tail (71–90 µm) with rounded end. Morphometric data of studied species are presented and intraspecific variation of their morphometrics and morphological characters is discussed. The list of the world Ditylenchus species is updated, and a dichotomous identification key and an updated tabular compendium for 63 valid species is provided.

The Afrotropical species of Pachyanthidium Friese are revised. Sixteen species are recognized in four subgenera. One new species, Pachyanthidium (Trichanthidium) anoplos sp. n. is described; and one species, Pachyanthidium (Trichanthidium) cucullatum (Friese), is reinstated as a valid species. Four new synonymy are proposed: Pachyanthidium minutulum Pasteels =Pachyanthidium (Trichanthidiodes) semiluteum Pasteels syn. n.; Anthidium africanum Smith = P. (P.) bicolor (Lepeletier) syn. n.; Pachyanthidium cordatum swellemdamense Mavromoustakis = Pachyanthidium (P.) cordatum (Smith) syn. n. and Anthidium cordatum var. salamense Friese 1931 = Pachyanthidium (P.) salamense (Friese 1915) syn. n. Identification keys for the Afrotropical species are given.

Examination of material representing the 24 previously named species and subspecies of Austrophilopterus resulted in recognition of only 6 of these as valid species and 18 as synonymies, including a previously established junior synonym and 17 new synonymies. These 6 species are redescribed and illustrated. One new species, A. thysi, is described from the type host Selenidera gouldii (Natterer).

The Indo-Pacific peristediid genus Satyrichthys Kaup, 1873 was first diagnosed as having a broad head with mesethmoid, postocular, parietal and preopercular spines. Later, most ichthyologists characterized Satyrichthys by its toothless jaws and strong preopercular spine. Kawai (2008) divided Satyrichthys into two genera, Satyrichthys and Scalicus, on the basis of a phylogenetic hypothesis, and redefined Satyrichthys. Seven species of Satyrichthys are recognized here, including one new species: S. clavilapis, S. laticeps, S. longiceps, S. milleri sp. nov., S. moluccensis, S. rieffeli and S. welchi. The new species is distinguished from its congeners in having equilateral-triangular rostral projections, 4 lip and 4 chin barbels, and no anterior directed spines on the upper lateral row of the caudal peduncle. Satyrichthys laticeps, previously treated as a junior synonym of S. moluccensis, is regarded as a valid species. The following new synonyms are noted: S. adeni, S. halyi and S. magnus are all junior synonyms of S. laticeps; S. isokawae is a junior synonym of S. moluccensis; and S. lingi is a junior synonym of S. welchi. In addition, a neotype is designated for S. moluccensis.

Acanthocyrtus croceus Womersley is confirmed as a junior synonymy of A. guianiensis. The juvenile description of Amazhomidia ducke is provided, and changes in chaetotaxy nomenclature are made based on them. Acanthocyrtus lineatus Womersley is redescribed based on type material and new diagnostic characters are revealed. Identification keys for both genera and a comparison for Entomobryinae genera with dental spines are provided. Amazhomidia has now three and Acanthocyrtus Handschin six valid species.

One new species of Parasphaerolaimus is described from a Brazilian estuarine system with intra-uterine development of its offspring. Parasphaerolaimus magdolnae sp. n. is distinguished from other species of the genus by the presence of only one anterior testis, spicules morphology and size and a gubernaculum without dorsal apophysis. The cuticle of the new species is striated and the position of the vulva is far posterior on the body, almost reaching the anus. The taxonomy of Parasphaerolaimus was also re-examined and two other species were transferred from Sphaerolaimus to Parasphaerolaimus after the last revision: P. pentasetus (Pastor de Ward, 1984) comb. n. and P. striatus (Allgén, 1935) comb. n. An updated identification key for all valid species of Parasphaerolaimus is included.

AbstractMegagrapha Melander and the four other New World genera named below are defined as a natural group which belong to the tribe Drapetini of the subfamily Tachydrominae. Both the genus group and the component genera are described and keys to genera and species are presented. One new genus, Chaetodromia Chillcott from Mexico is described, with two new species. One new species is described in Megagrapha, five in Austrodromia Collin, four in Allodromia Smith, and 17 in Micrempis Melander. Micrempis testacea Melander is transferred to Allodromia, and Allodromia curviradius Smith is transferred to Micrempis. Megagrapha exquisita (Malloch) is resurrected from synonymy as a valid species. Lectotypes are designated for Micrempis minuta (Melander), M. nana Melander, and M. varipes Melander.

The members of the genus Pelthydrus are small-sized aquatic beetles which belong to the water scavenger beetle family Hydrophilidae. At present the lineage includes 63 valid species mainly occurring in Asia, with 21 known from China (Bian et al. 2008, 2009; Hansen 1999; Schönmann 1995). One new species is described here, which belongs to the Pelthydrus sculpturatus species group, bringing the total number of species within the group to seven (Schönmann 1995). One additional species is reported from China for the first time. Specimens were collected from Yunnan Province and are deposited in IAECAS (Institute of Applied Ecology, Shenyang, Chinese Academy of Sciences).

The species group effusus of the genus Pyrops Spinola, 1839 is reviewed and the nomenclatural history of the genus Pyrops is briefly summarized. One new species from eastern Borneo, Pyrops synavei sp. nov., is described. P. gunjii (Satô & Nagai, 1994) stat. nov. is proposed as a valid species instead of a subspecies of P. whiteheadi (Distant, 1889). P. maquilinganus (Baker, 1925) is removed from the effusus group and placed back into the candelaria group. P. cyanirostris (Guérin-Méneville, 1845) is removed from the group and not attributed to any of the currently defined species groups. An illustrated key to the species of the group with the addition of P. intricatus (Walker, 1857) and a distribution map are given. The effusus group is restricted to Borneo and adjacent Laut Island and presently contains 4 species: P. effusus (Distant, 1891), P. gunjii (Satô & Nagai, 1994) stat.nov., P. synavei sp. nov. and P. whiteheadi (Distant, 1889). Trophobiosis observations with the gecko Gehyra mutilata (Wiegmann, 1835) (Reptilia: Squamata: Gekkonidae) and two species of cockroaches (Insecta: Blattodea), one Dorylaea sp. and an unidentified species of Pseudophyllodromiinae, are reported and illustrated for P. whiteheadi; observation with a cockroach, Dorylaea sp., is reported for P. intricatus.
