Pseudascarophis kyphosi n.gen., n.sp. (Nematoda: Cystidicolidae) is described for specimens collected from the stomach of Kyphosus cinerascens (Forskål) from the southeast coast of Japan. The new genus is distinguished from all other genera of Cystidicolidae by its oral structure (presence of four submedian, longitudinally directed, digitiform processes in the buccal cavity projecting slightly beyond the oral opening; smooth margined mouth; absence of submedian labia and sublabia; and unique shape of the medial region of the pseudolabia) and numbers of caudal papillae in the male (3 pairs preanal, 7 pairs postanal).

A new genus and species of Desmodoridae was found in deep-sea sediments of the Campos Basin. Although the cuticle annulation of the new species is similar to members of Desmodorinae, many morphological features are strong enough to classify it within the Spiriniinae. Spirodesma magdae nov. gen. nov. sp. is characterized mainly by the presence of a unique form of unispired amphids, with circular amphideal fovea, and a buccal cavity with three equal teeth, one dorsal and two ventrosublateral.

Rhabdias americanus n.sp., Rhabdias ranae Walton, 1929, Rhabdias fuscovenosa (Railliet, 1899), and Rhabdias eustreptos (MacCallum, 1921) from amphibians and reptiles of southern Ontario are described. Rhabdias americanus n.sp. and R. ranae have two large lateral pseudolabia beside the oral opening whereas R. fuscovenosa and R. eustreptos each have six lips arranged in lateral groups of three. Rhabdias americanus n.sp. is distinguished from R. ranae by the shape of the pseudolabia and by the presence of a cuticular ring on the posterior border of the buccal cavity which is absent in the buccal cavity of R. ranae. Rhabdias fuscovenosa is distinguished from R. eustreptos by its significantly smaller size and by the shape of the posterior quarter of the body which is straight in R. fuscovenosa and corkscrew shaped in R. eustreptos. Rhabdias fuscovenosa is the only species examined in which eggs in the uteri of gravid hermaphrodites were always at an early cleavage stage of development. In other species examined most eggs in the uteri contained first-stage larvae.

Patagonema iubatum gen. nov. sp. nov. is described from a sandy beach at Playa Pozo, Golfo Nuevo, Argentina. It resembles Oncholaimidae (Nematoda: Enoplida) and it is characterized by a buccal cavity comprising a combination of three teeth and three mandibular ridges with small teeth. The new genus is also characterized by the presence of papillose pre-cloacal supplements, cephalated spicula and a gubernaculum with dorsal apophysis and lateral piece, and a new demanian system configuration. Patagonema iubatum sp. nov. has 9–11 papillae-like pre-cloacal supplements, short and cephalated spicula and a gubernaculum with dorsal apophysis and pointed lateral piece. Its position inside Oncholaimidae is discussed.

The Campterophlebiidae is the largest family of fossil damsel-dragonflies, containing more than 60 species described from Lower Jurassic–Lower Cretaceous strata of Europe and Asia. This group is especially diverse in the Middle–Late Jurassic strata in Inner Mongolia, northeastern China, with some very large species (Zhang et al., 2006, 2008, 2013; Nel et al., 2007, 2008, 2009; Petrulevičius et al., 2011; Li et al., 2013; Zhang et al., 2013; Zheng et al., 2016, 2017). Thus it is surprising that we found a new representative of these damsel-dragonflies, belonging to a group of genera characterized by a very particular shape of the forewing cubito-anal area. This fossil has a unique shape of the forewing median vein, allowing its attribution to a new genus and species. It increases our knowledge about the palaeobiodiversity of this impressive group of Odonata.

The group of Macrobiotus species having claws of the tenuis-type is discussed and a new genus, named Tenuibiotus, is instituted. The tenuis-type claws are characterised by the fusion of the primary and secondary branches over a long distance so that the common tract is longer than that found in other members of the Macrobiotidae. Distally, the secondary branch is clearly shorter than the primary branch, and forms with it almost a right angle. In all the known species attributable to the new genus, the buccal tube is narrow, the buccal cavity is small with small peribuccal lamellae; the eggs are laid freely and have conical or trunco-conical processes.

All polymastiid sponges displaying ornamented exotyles are reviewed and their morphological affinities are reconsidered. The study embraces all known species ofProteleia,Sphaerotylus,TrachyteleiaandTylexocladusas well as several species ofPolymastia. A new genus,Koltunia, is established for the Antarctic speciesProteleia burtonibased on the unique shape of distal ornamentations of its giant exotyles and on the absence of a spicule palisade in its cortex, a rare feature among the polymastiids. Three new species ofSphaerotylusare described –S. renoufifrom the British Isles,S. strobilisfrom South Africa andS. tjalfeifrom West Greenland. Transfer of one New Zealand species fromPolymastiatoProteleiaand of one Chilean species fromPolymastiatoSphaerotylusis proposed. The present study provides a background for future integrative phylogenetic analyses based on comprehensive molecular and morphological datasets which should reveal the natural relationships between the polymastiid taxa.

Lacrimacandona n. gen. with its type species Lacrimacandona wisei n. sp. from the San Marcos artesian well on the Texas State University campus (Hays County, Texas, USA) is proposed as a new genus of the subfamily Candoninae. The new species is sexually dimorphic, and so far no congeneric species have been found. The new genus has the following distinguishing characters: subtriangular carapace tapering posteriorly, uropod with a claw-like anterior seta and two short claws, one long “a” setae on male maxilliped, very large asymmetric clasping organs in males, unique shape and size of hemipenis, and unique occurrence of setae on segments.

Two new species, including a new genus of rhigonematid nematode, are described from Archispirostreptus tumuliporus (Spirostreptida; Diplopoda) from Malawi. Brumptaemilius justini n.sp. resembles Brumptaemilius sclerophorus, the type species, and Brumptaemilius oschei in the form of the area rugosa in the male. It differs from male B. sclerophorus in having a caudal appendage which is longer and supports the last pair of caudal papillae; this pair is anterior to the caudal appendage in B. sclerophorus. Male B. justini differ from those of B. oschei in having a shorter caudal appendage, distinctly set off from the rest of the body, and in possessing a field of tiny bosses on either side in the anal region. Waerebekeia n.gen., with type species Waerebekeia simoni n.sp., resembles Brumptaemilius since males have a urceolate buccal cavity with three prominent pennate cuticular projections and three trifid teeth at its base. The genera are distinguished by the shape of the oral opening in the male (laterally elongate in Waerebekeia; subtriangular in Brumptaemilius), by the absence of an area rugosa and by the more dorsal position of the third papilla pair in male Waerebekeia.

Nemhelix bakeri n.gen., n.sp. (Cosmocercinae), from the genital tract of Helix aspersa Miiller (Helicidae) in France, is described. The new genus is characterized by a rounded oral opening without lips. The authors presume that the Cosmocercinae arose in amphibians and became parasites of molluscs secondarily and that the two species became molluscan parasites independently.

The new genus and species Yeatesinia barbata gen. n., sp. n. is described from a sand dune habitat in New Zealand. The new genus is characterised by a body length of 299-357 μm in females and 304-361 μm in males, lip region rounded dorso-ventrally, broad laterally, dorsally inclined, lateral sides of lip region with two large, horn-like, projections, each bearing one seta at its base, each amphid surrounded by three setiform sensilla, oral opening a broad transverse slit located on the dorsal body surface, and different structure of cuticle in the dorsal and ventral body sectors. This combination of unique morphological characters clearly separates the new genus from all other members of the Plectidae. The phylogenetic affinities of Yeatesinia gen. n. and its relationships to other genera of the family Plectidae are discussed.
