Two new corticioid species, Hydnophlebia sinensis and H. subchrysorhiza, are described and illustrated from China. Hydnophlebia sinensis was collected from northern China (Beijing, Jilin and Shaanxi Provinces), while H. subchrysorhiza was collected from southern China (Hainan, Hunan and Yunnan Provinces). The two new species belong to the H. chrysorhiza species complex and are similar to each other with few morphological differences. However, they are phylogenetically independent in both the ITS-LSU tree of Meruliaceae and the ITS tree of Hydnophlebia. In the trees, H. sinensis was sister to H. sp., whilst H. subchrysorhiza was closely related to H. chrysorhiza. Our analyses show that we do not have H. chrysorhiza in China but possess two undescribed sibling species

Mite predators of synanthropic flies similar to Macrocheles kraepelini (Berlese) are described as a new complex of species belonging to the Macrocheles glaber species group. Two new species in the kraepelini complex are described, M. tantalus and M. hallidayi. The male of M. kraepelini is described for the first time. Information on the distribution and phoretic associations of all three species is presented. Macrocheles hallidayi and M. kraepelini are sibling species, which, when sympatric, differ in adult body size by the same ratio as the holarctic sibling species pair of M. perglaber and M. glaber.

Amphiglena is a clade of sabellid annelids that has 12 named species from around the world. New COI and 18S sequences were combined with some available data to generate a molecular phylogeny for Amphiglena. Two new species of Amphiglena are described as a result, using an integrative approach combining molecular evidence with morphological descriptions using histology, 3D reconstructions and electron microscopy. Amphiglena seaverae n. sp is described from Florida, USA and Amphiglena joyceae n. sp. from Edithburgh, South Australia. Our analyses also reveal a previously underemphasized species complex in the Mediterranean, with up to six undescribed species. This highlights the potential diversity of these minute annelid worms yet to be named.

Wood-inhabiting fungi play crucial roles as decomposers in forest ecosystems and, in this study, two new wood-inhabiting corticioid fungi, Hyphoderma puerense and H. tenuissimumspp. nov., are proposed, based on a combination of morphological features and molecular evidence. Hyphoderma puerense is characterised by effused basidiomata with smooth to floccose hymenial surface, a monomitic hyphal system with clamped generative hyphae and ellipsoid basidiospores. Hyphoderma tenuissimum is characterised by resupinate basidiomata with tuberculate to minutely-grandinioid hymenial surface, septate cystidia and cylindrical to allantoid basidiospores. Sequences of ITS and nLSU rRNA markers of the studied samples were generated and phylogenetic analyses were performed with Maximum Likelihood, maximum parsimony and Bayesian Inference methods. These analyses showed that the two new species clustered into Hyphoderma, in which H. puerense grouped with H. moniliforme and H. tenuissimum formed a singleton lineage. In addition, an identification key to Chinese Hyphoderma is provided.

Fuscoporia (Hymenochaetaceae) is characterized by annual to perennial, resupinate to pileate basidiocarps, a dimitic hyphal system, presence of hymenial setae, and hyaline, thin-walled, smooth basidiospores. Phylogenetic analyses based on the nLSU and a combined ITS, nLSU and RPB2 datasets of 18 species of Fuscoporia revealed two new lineages that are equated to two new species; Fuscoporia ramulicolasp. nov. grouped together with F. ferrea, F. punctatiformis, F. subferrea and F. yunnanensis with a strong support; Fuscoporia acutimarginatasp. nov. formed a strongly supported lineage distinct from other species. The individual morphological characters of the new species and their related species are discussed. A key to Chinese species of Fuscoporia is provided.

Squat Lobsters

The genus Munida Leach, 1820 is the most diverse group within the squat lobsters, with approximately 250 described species. The extreme morphological similarity among certain species makes very difficult to identify diagnostic characters, and the real diversity of the group is probably underestimated. Here, two new species of the genus Munida from Taiwan previously identified as M. distiza Macpherson, 1994 and M. militaris Henderson, 1885, respectively, are described and illustrated. The two species are identified by subtle and constant morphological differences, which match clear molecular divergences in the 16S and COI genes. These results confirm the taxonomic value of slight morphological differences, and emphasize the need for more detailed analysis to clarify the phylogenetic relationships within the genus.

Abstract BackgroundCurrently, 24 species of Encotyllabe Diesing, 1850 (Monogenea: Capsalidae) are listed in WoRMS, but the validity of many species has been questioned due to deficient or incomplete descriptions. On the other hand, almost all species in the genus have been described from one host species or closely related host species, suggesting host specificity, but other species, specifically Encotyllabe spari Yamaguti, 1934, have been reported at least from 19 species belonging to nine families in two orders (Perciformes and Scorpaeniformes) from Japan, the Arabian Gulf and Brazil. Concerning Brazilian records of Encotyllabe spari (but also as Encotyllabe cf. spari); seven host species belonging to four families and two orders have been reported as hosts for this species. The aim of this study was to describe two new species of Encotyllabe from Brazil, previously considered as E. spari.MethodsDuring 2016, we examined specimens of Orthophristis ruber (Cuvier) (Haemulidae) and Pagrus pagrus (Linnaeus) (Sparidae) caught off the coast of Cabo Frio, Rio de Janeiro, Brazil by local fishermen. Specimens of Encotyllabe were collected from the pharyngeal plates of the hosts. Morphological and morphometric (multivariate analysis of proportional measurements standardized by total length) and molecular analysis (LSU rRNA and cox1 gene) were performed in order to identify the collected monogenea. ResultsThe presence of two new species of Encotyllabe, Encotyllabe yamagutii n. sp. and Encotyllabe haemuli n. sp., parasitizing the pharyngeal plates of Pagrus pagrus and Orthopristis ruber, respectively, is strongly suggested by the three approaches used in this study. The main morphological differences from the most related species include a combination of body size, shape of the penis, and size and position of the testes.ConclusionsSpecimens of Encotyllabe, hitherto recorded as E. spari or E. cf. spari, belong to two new species. Our results suggest that the host specificity for members of Encotyllabe and specimens registered as E. spari, other than those from the original description, must be revisited.

Two new species of Lactarius from Dinghu Mountain, Guangdong Province in southern China were described based on both morphological characters and phylogenetic analysis of internal transcribed spacer (ITS) sequences. Lactarius verrucosporus sp. nov. is characterized by reddish brown pileus with white and decurved margin, pale cream lamellae, globose to subglobose basidiospores with isolated warts, thin pileipellis composed of globose subterminal cells and inflated terminal elements. Lactarius nigricans sp. nov. is recognized by greyish brown pileus, beige lamellae, amyloid basidiospores with high ridges, subcylindrical to subfusiform caulocystidia, thick pileipellis with long terminal cells. Both molecular and morphological analysis consistently confirm that L. verrucosporus and L. nigricans belong to Lactarius subgenera Russularia and Plinthogalus, respectively, and both species are distinct from all described species of these two subgenera. The morphological differences of these two novel species with their closely related taxa are discussed.

The eustatic movements triggered by glaciations during the Quaternary have shaped the landscape of Brazilian Atlantic Coast. Cyclic sea-level changes either isolated or connected freshwater fish populations, impacting their distribution and diversification. Rhamdia quelen has been widely recorded from the Brazilian Atlantic Coastal rivers, but it is also considered a species complex. A phylogeographic study carried out using three molecular markers of mtDNA and one of nDNA in the populations of Rhamdia from the hydrographic basins of Southern Atlantic Coast of Brazil recovered three evolutionarily distinct groups: one represented by the populations found in lowlands of all studied watersheds; the second group composed of populations found in the upper tributaries of the rio Araranguá, rio Mampituba and rio Tramandaí; and a third group found exclusively in the upper portions of rio Tubarão. The genetic divergences among these three lineages of Rhamdia is discussed according to sea level changes in the Quaternary. Two new species of Rhamdia are diagnosed and described based on morphological and molecular evidence.
