Gerronema kuruvense sp. nov. and G. keralense sp. nov. are described from Kerala State, India, in the light of both morphology and molecular phylogenetic analysis. Comprehensive descriptions, photographs of both the basidiomes and the micro-structures, and comparisons with morphologically similar and phylogenetically related species are provided. Both morphology and nrITS-rDNA sequence-based molecular phylogenetic analysis proved the novelty of the species and their placement in the genus Gerronema. Both the species were collected from highland riverine islets.

A New Species

Zehneria grandibracteata, a new species of Cucurbitaceae from western Kenya, is described here, based on morphological and molecular data. It has long been misidentified as the widely-distributed species Z. scabra. However, it differs by its ovate leafy probract at the base of the inflorescences, subglabrous condition of the entire plant, shorter receptacle-tube and filaments, as well as denser and sessile inflorescences. Furthermore, the molecular phylogenetic analysis of Zehneria, based on nrITS sequences, further supports the argument that Z. grandibracteata should be segregated from Z. scabra.

Crangonyx ephemerus n. sp. and Crangonyx pseudoephemerus n. sp. are described from the headwaters of the St. Marks River in Leon County, Florida, based on detailed morphological and molecular comparisons with the closely related species Crangonyx floridanus Bousfield, 1963. The morphological and molecular data, including three species delimitation models, lend support to the hypothesis that the taxon C. floridanus sensu lato represents a species complex. Diagnostic morphological characteristics are highlighted and discussed within this group to assist in future morphological analyses.

Stellaria multipartita sp. nov. (Caryophyllaceae) from Chongqing, China, is described and illustrated based on morphological and molecular data. The new species is similar to S. radians by the palmately fimbriate petals with more linear divisions. Different characters are: shape of the leaves (oblong-triangular to ovate-triangular vs. oblong-lanceolate to ovate-lanceolate in S. radians), petals (10–12-cleft vs. 5–7-cleft in S. radians), and seeds (with mamillate ornamentation vs. scrobiculate ornamentation in S. radians). A molecular phylogenetic analysis supports the recognition of Chongqing population as a new species for science.

Tetrataenium mianguaqi, a traditionally used medicinal herb in Cangyuan County, SW Yunnan, China, is described as a species new to science and illustrated. Molecular phylogenetic analysis based on nuclear ITS well supports its belonging to Tetrataenium sensu stricto. The new species can be easily distinguished by its unique peltate, palmatilobate basal and lower leaves from the other five Chinese Tetrataenium species.

The recent delimitation of the cambalopsid genera Hypocambala and Glyphiulus is debatable. The focus of controversy is whether the presence of crests on the trunk rings is an appropriate key character dividing these two genera. To address this issue, we conducted a molecular phylogenetic analysis including species with or without crests belonging to Hypocambala and species with crests belonging to Glyphiulus. The results of the phylogenetic analysis suggest that cambalopsids with crests are monophyletic and sister to a species without crests. Hypocambala polytricha, a cambalopsid with crests that is in a clade with crested Glyphiulus species, should be transferred to Glyphiulus. Therefore, a new combination is proposed, Glyphiulus polytrichus comb. nov. In addition, a discussion on the boundary between these two genera and a description of a new species, Hypocambala zizhongi sp. nov., are provided.

Lithobius (Ezembius) longibasitarsussp. n. and Lithobius (Ezembius) datongensissp. n. (Lithobiomorpha: Lithobiidae), recently discovered from Qinghai-Tibet Plateau, China, are described. A key to the species of the subgenus Ezembius in China is presented. The partial mitochondrial cytochrome c oxidase subunit I barcoding gene was amplified and sequenced for eight individuals of the two new species and the dataset was used for molecular phylogenetic analysis and genetic distance determination. Both morphology and molecular data show that the specimens examined should be referred to Lithobius (Ezembius).

Morphological And Molecular Data

Because of their relatively simple body plan, the number of morphological characters used to differentiate between closely related nematode genera is often limited. In addition, boundaries among genera sometimes become blurred due to the appearance of new trait combinations as more new species are described. Molecular phylogenetic analyses can address the shortcomings of morphological taxonomy by clarifying relationships among closely related species and genera and can help identify which morphological characters are taxonomically informative. Here, we describeLaxus sakihariiaesp. n. from shallow subtidal sands on Sesoko Island in the Okinawa prefecture, investigate phylogenetic relationships with other stilbonematine species and genera based on SSU rDNA sequences, and provide the first LSU rDNA sequence for the subfamily. The new species can be easily distinguished from all other species of the genus by the presence in the male of subventral and ventral rows of stout and spine-like setae in the pre- and postcloacal regions. This feature suggests affinities with the closely related genusLeptonemella, although the SSU consensus tree clearly shows that the new species forms a monophyletic clade together with the otherLaxusspecies for which sequences are available. The structure of the cephalic capsule inL. sakihariiaesp. n., which consists of a block layer between the median and basal zones of the cephalic cuticle, is consistent with the placement of this species. This trait is not currently used as a diagnostic feature, but our finding suggests that the structure of the cephalic capsule may be taxonomically useful for differentiating between some stilbonematine genera.
