Species Descriptions

The family Sphaerolaimidae Filipjev, 1918 includes nematodes that are characterized by the finely striated cuticle, round amphids, broad buccal cavity with longitudinal ribs, and single anterior ovary in females. Parasphaerolaimus species from this family are found in intertidal and subtidal sediments and have also been reported from mangroves and estuaries. Parasphaerolaimus pilosus sp. n. is characterized by the moderately plump body, presence of lateral alae, long cervical setae, small amphids in males, and relatively short spicules. As a result of a comprehensive evaluation of species descriptions, eight species in the genus Parasphaerolaimus are recognized valid, and an identification key to species level is provided.

Species Descriptions

The discovery of asellotan isopod species resembling Stenetrium, but with male pleopods like those in the genus Pseudojanira Barnard, 1925 necessitated a re-examination of the taxonomy of the family Pseudojaniridae Wilson, 1986. Data presented in this paper support the assignment of the Pseudojaniridae to the superfamily Stenetrioidea Hansen, 1905, thus eliminating the superfamily Pseudojaniroidea Wilson. A new definition of the Stenetrioidea and a generic key are provided. The genus Pseudojanira and its species are revised, including a species-level key. A study of Pseudojanira investigatoris Poore and Just, 1990 has revealed two new cryptic species, Pseudojanira fremantlensis, sp. nov. and Pseudojanira justi, sp. nov. Some paratypes and other specimens originally classified as Pseudojanira investigatoris are reassigned to other species. Descriptions of two new monotypic genera of the Pseudojaniridae, Schottea taupoensis, gen. nov., sp. nov. andAdajinoperus tetanomorphus, gen. nov., sp. nov. further expand the recognised morphological diversity of this family. A new genus of Stenetriidae, Lexcenium, gen. nov., with two new species, L. poorei, sp. nov. and L. greenensis, sp. nov., provides additional evidence of the diverse, non- homologous forms of the ‘stylet-like’ appendix masculina within the superfamily.

Mushrooms with a thin-fleshed pileus that becomes plicate on opening, deliquescent lamellae and dark brown to blackish basidiospores are commonly called coprinoid mushrooms. The genusCoprinellusis one of the important lineages of coprinoid mushroom in the family Psathyrellaceae. Species-level taxonomy inCoprinellusis based mainly on the presence or absence and the structure of veil and cystidia on the pileus, of cystidia on the lamellae and on basidiospore morphology. In this study, four new species ofCoprinellus(Co.campanulatus,Co.disseminatus-similis,Co.pakistanicusandCo.tenuis) are described from Pakistan. Species descriptions are based on morphological and molecular data. Phylogenetic analyses based on nuc rDNA ITS region show that the new speciesCo.campanulatusandCo.disseminatus-similisare clustered in a clade including members of section Micacei;Co.tenuisfalls in a clade with members of section Domestici; andCo.pakistanicusrecovered in a separate clade adjacent to other recently described clades of genusCoprinellus. Morpho-anatomical descriptions of the new species and comparison with closely allied taxa are provided. With this study, the number of known species ofCoprinellusin Pakistan has reached eight.

A new species of free-living marine nematode is described from Itapuã beach, northeast of Brazil. Pomponema veronicae sp. n. differs from other species of Pomponema by having buccal cavity with large pointed dorsal tooth, two subventral teeth and pairs of denticles, gubernaculum with two L-shaped lateral plates and having a membrane at its distal end that connects to L-shaped plate, and presence of a ventral orifice at distal end of L-shaped plates. It also differs from other species in the size of spicules and gubernaculum. The new species is considered most closely related to Parapomponema species because of the L-shaped lateral plates of gubernaculum, but the taxonomic status of Parapomponema was reviewed and Parapomponema and Propomponema are now synonymized with Pomponema. Pomponema cyatholaimoides is considered as a species inquirendum and Pomponema carinatum is accepted as Pomponema loticum. An updated identification key to species of Pomponema is included.

Abstract Coomansus batxatensis sp. nov., recorded from Vietnam, is described and illustrated and its phylogenetic relationship within the Mononchida is analysed. The molecular data (18S and 28S ribosomal DNA) are provided for the new species. The new species is characterized by small body size (body length, L = 0.7–0.9 mm); buccal cavity sub-rectangular in shape, flattened at base, 21–24 × 12–13 μm or 1.9 (1.7–2.0) times as long as wide; posterior position of dorsal tooth apex (59–63% from the base of buccal cavity); pars refringens vaginae with faint and small (2.5 × 1.7 μm) teardrop-shaped pieces, short pars distalis vaginae; and males with short spicules (50–51.5 μm) with rounded head and conical blade part. The new species is close to Coomansus parvus but differs from it by the smaller buccal cavity size, more posterior position of the dorsal tooth apex, longer tail and presence of males. An updated identification key to Coomansus species and a compendium of all the species known are presented.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

A New Species

A new species of the chirostylid squat lobster genus Uroptychodes Baba, 2004, U. fuscilineatus, is described and illustrated on the basis of a single ovigerous female from the Uraga Channel, central Japan, at depth of 250 m. The new species appears most similar to U. spinimarginatus (Henderson, 1885) and U. yapensis Dong, Gan & Li, 2021 among the 13 known congeners, but is notable in the pereopod 2 not being definitely more slender than the pereopods 3 and 4 and the remarkably spinose pereopods 1–4. A possible association of the new species with crinoid is suggested. An updated identification key to species of Uroptychodes is presented.
