Summary Litylenchus crenatae n. sp., isolated from leaf galls of Fagus crenata from Japan, is described and figured. The new species is characterised by its dimorphism in adult females, six (or more) lateral lines, a more or less pointed tail tip in both sexes, male bursa arising posteriorly and reaching to near tail tip, presence of a quadricolumella and a post-uterine sac in females. Litylenchus crenatae n. sp. is distinguished from its only congener, L. coprosma, by the number of lateral lines, six or more vs four; the lip morphology, offset with very shallow constriction or dome-shaped without clear constriction vs clearly offset; tail tip morphology, more or less pointed vs blunt; and structure of the median bulb, weakly muscular with a clear valve vs not muscular with an obscure valve. The molecular phylogenetic analysis confirms that the new species is close to, but clearly different from, L. coprosma.

Ektaphelenchus ibericus n. sp. is described and figured. The new species was isolated from pine packaging wood from Spain that was inspected in Ningbo harbour, China, in 2011. Ektaphelenchus ibericus n. sp. is characterised by lip region without clear constriction, relatively short stylet (11-15 μm) lacking basal knobs, and four lateral lines. The female post-uterine sac is less than one body diam. long, rectum and anus are absent, and the tail is conoid with a sharply pointed terminus. Males are rare and have a conoid tail with a sharply pointed terminus, spicules mitten-shaped, 12.8 μm long (chord) and smoothly curved with a high and bluntly rounded condylus and bluntly pointed rostrum, distal end broadly rounded, and three pairs of ventral caudal papillae present. The separate species status is also supported by molecular phylogenetic analysis based on partial SSU, ITS1/2 and partial LSU sequences.

A New Species

Pilaira australis, a new species of fungus in the coprophilous genus Pilaira, was isolated from emu (Dromaius novaehollandiae) faeces and is described. Morphologically, the species resembles other species in the genus, particularly P. moreaui, except differs in its unique combination of sporangiophore height and sporangiospore length. Molecular phylogenetic analysis indicates that P. australis is distinct from other species in the genus with two regions, the internal transcribed spacers (ITS) and a fragment of the pyrG gene, showing 91% and 90% identity to the nearest species, respectively. Ultrastructure features and carbon utilisation were determined for P. australis, and may provide characteristics for species identification in this genus.

A New Species

Codonopsis atriplicifolia (Campanulaceae) from western Sichuan, China, is described here as a new species, which is similar to C. subscaposa in a number of characters. The results of molecular phylogenetic analysis of 25 species of Codonopsis based on chloroplast DNA fragments (matK, petD with petB-petD, rbcL) show that C. atriplicifolia is closely related to C. farreri. In morphology, the new species is distinctly different from the allied species by its linear-lanceolate leaves with subentire to pinnatipartite margins.

A New Species

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.

A New Species

A new species of the continental shelf hyperbenthic genus Pilarella is described, the first from the Indo-Pacific. This is the second species of Pilarella known, and the first description of a male in the genus. The new species is easily distinguished from other species of Pilarella (P. longicornis) based on: (1) short caudal rami, approximately 1.5 times longer than wide; (2) 2 setae on the mandibular endopod; (3) 6 setae on the maxillular coxal epipodite; and (4) in the female, a short left antennule reaching the posterior border of the genital double-somite. The new diagnosis of Pilarella differs from Metacalanus in the separation of ancestral segments IX–XII and XIV–XV of the antennule, and the presence of 5–6 setae on the maxillular praecoxal arthrite. Pilarella is also separated from Metacalanalis based on the absence of a seta on the third ancestral segment of the antennary exopod, the symmetry of legs 1–3, the presence of a medial basal seta on the female leg 5, and 2 lateral exopodal spines on the female leg 5. A molecular phylogenetic analysis of some representative genera of the family Arietellidae, including the present new species, recovers two arietellid clades (Metacalanus- and Arietellus-clades) as in previous studies. Dichotomous keys for the genera of Arietellidae and the species of Pilarella are included.

This report provides a description of Primula sunhangii from the Shennongjia Forestry District, Hubei Province in Central China, which is categorized as a new species of the primrose family. Primula sunhangii is morphologically similar to P. involucrata Wall. ex Duby in terms of its simple umbel, efarinose, and prolonged bracts. However, P. sunhangii is distinguished by its glabrous sepal, short petiole (compare with blade) and cylindrical calyx and capsule. Molecular phylogenetic analysis based on nuclear and cpDNA genes demonstrates that P. sunhangii and P. involucrata are closely related. Combining genetic and morphological data, the recognition of P. sunhangii as a unique new species is supported.

The genus Sibogasyrinx has to date included only four species of rare deep-water Conoidea, each known from few specimens. In shell characters it strongly resembles three distantly-related genera, two of which, Comitas and Leucosyrinx, belong to a different family, the Pseudomelatomidae. A molecular phylogenetic analysis of a large amount of material of Conoidea has revealed the existence of much additional undescribed diversity within Sibogasyrinx from the central Indo-Pacific and temperate Northern Pacific. Based on partial sequences of the mitochondrial cox1 gene and morphological characters of 54 specimens, 10 species hypotheses are proposed, of which six are described as new species: S. subula sp. nov., S. lolae sp. nov., S. maximei sp. nov., S. clausura sp. nov., S. pagodiformis sp. nov. and S. elbakyanae Kantor, Puillandre & Bouchet sp. nov. One of the previously described species was absent in our material. Most of the new species are very similar and are compared to Leucosyrinx spp. Species of Sibogasyrinx are unique among Conoidea on account of the high intrageneric variability in radular morphology. Three distinct radula types are found within Sibogasyrinx, two of which are confined to highly supported subclades.
