Three new species of the tribe Synergini (Hymenoptera, Cynipidae), i.e., Lithosaphonecrus arcoverticus Liu, Zhu et Pang, sp. n. Lithosaphonecrus decarinatus Liu, Zhu et Pang, sp. n. and Saphonecrus emarginatus Liu, Zhu et Pang, sp. n. are described from Hunan, China. The three species have emerged from the same galls collected on Lithocarpus glaber (Thunb.) in December, June, and April, respectively. Phylogenetic reconstruction of Synergini based on mtDNA COI and rRNA 28S D2 genes resolved two independent monophyletic clades exclusively associated with Lithocarpus plant hosts, i.e., the genus Lithosaphonecus and the lithocarpii species complex of Saphonecrus. The three species each have a sister relationship with a congener in Taiwan, an island off the southeastern coast of continental China. This recurrent disjunct distribution and relatively low COI sequence variation between the sister species in each species pair are considered attributable to the formation of the Taiwan Strait in Holocene ca 10,000 years ago. We also discussed the possible speciation mechanism for Lithosaphonecrus due to seasonality and topography in subtropical China. Finally, we addressed the need for conservation consideration in urbanization planning.

Peyssonneliaceae represents a monophyletic clade of red encrusting algae classified Peyssonneliales. Molecular analyses have been important for revealing unknown diversity in this family, which includes small, cryptic organisms, frequently distinguished solely by discrete anatomical characters. Brazil however, remains virtually unknown. To assess this diversity, phylogenetic and barcoding analyses using rbcL, COI-5P and SSU data, as well as morpho-anatomical analyses were performed. Here we report the first occurrence of two genera on the Brazilian coast: Ramicrusta and Incendia, and describe three new species: Ramicrusta fujiiana sp. nov., Ramicrusta paradoxa sp. nov. and Incendia yoneshigueana sp. nov. Ramicrusta was resolved as a monophyletic clade in the three reconstructed phylogenies, and had congruent topologies. In the rbcL phylogeny, Ramicrusta fujiiana formed a well-supported clade sister to a well-supported clade including R. aranea (Vanuatu, type locality) and R. textilis (Jamaica, type locality). Morphological characters of R. paradoxa are not in agreement with the original description of the genus. Therefore, we present an updated and broader concept of Ramicrusta. Incendia was resolved as a monophyletic clade with full support for rbcL. Incendia yoneshigueana is in a sister relationship with I. glabra (Vanuatu, type locality). This study extends the distributions of Ramicrusta and Incendia, proposes three new species, and confirms the effectiveness of rbcL, COI-5P and SSU in inferring phylogenetic relationships and delimiting species in the Peyssonneliales. The integrative approach established clear taxonomic concepts for the studied genera and species, and identified useful characters for genera delimitation in Peyssonneliaceae.

Sinopoda spiders are a diverse group with limited dispersal ability. They are remarkably sympatric among related species, which often results in misidentification and incorrect matching of sexes. In order to understand the evolutionary relationships and revise the taxonomy problems in this genus, we offer the first molecular phylogeny of Sinopoda. Our results strongly support the monophyly of Sinopoda and its sister relationship with Spariolenus and reject the monophyly of the S. okinawana species group. We establish three new species groups based on both molecular and morphological data. Our phylogeny also illuminates some taxonomic issues and clarifies some species limits: (1) Supporting the newly revised matching of sexes in S. longiducta and S. yaanensis by Zhong et al. (2019). (2) The original description of S. campanacea was based on mismatched sexes. S. changde is proposed as a junior synonymy of S. campanacea, while the original female ‘S. campanacea’ is here described as a new species: S. papilionaceous Liu sp. nov. (3) The type series of S. serpentembolus contains mismatched sexes. The female is considered as S. campanacea, while we here report the correctly matched females of S. serpentembolus. (4) We describe one additional new species: S. wuyiensis Liu sp. nov. Our first molecular phylogeny of Sinopoda provides a tool for comparative analyses and a solid base for the future biodiversity and taxonomic work on the genus.

This study represents the first phylogenetic reconstruction of lumbrinerid genera using parsimony analyses of 38 morphological characters. Following higher-level phylogenetic analysis, Oenone (Oenonidae) was selected as outgroup. The analysis was restricted to type species for each genus, yielded 24 equally parsimonious trees, which after successive weighting were reduced to one tree (CI= 0.7396). The topology of this tree revealed the separation of the family into four main clades: 1. Lysarete, 2. Arabellonereis, 3. Scoletoma, Lumbrineris, Hilbigneris gen. nov., Kuwaita, Lumbricalus, Sergioneris gen. nov. and Eranno, and 4. Abyssoninoe, Cenogenus, Lumbrinerides, Lumbrineriopsis, Augeneria, Loboneris gen. nov., Gallardoneris gen. nov., Helmutneris gen. nov., and Gesaneris gen. nov.; the position of Ninoe is unclear. A diagnosis of each genus is provided, including the description of six new genera and three new species. A key to lumbrinerid genera is included.

We used both morphological and genetic approaches to investigate and to describe a new Mediterranean sponge species of the genus Protosuberites from the estuarine-anchialine Bue Marino Cave of Sardinia (Tyrrhenian Sea). The morphotraits of the specimens were compared versus congeneric species with the strongest affinities, covering the genus geographic range worldwide. Protosuberites mereui sp. nov. is light yellow, thinly encrusting, devoid of any special ectosomal skeleton, with spicular complement of tylostyles of three size classes, single or arranged in bundles/tufts, with round to suboval heads. The new species is characterized by an exclusive diagnostic trait recorded for any cave-dwelling Protosuberites i.e. suboval and basally plated resting bodies with a foraminal aperture ornate by a collar. Resting bodies were found in the basal spongin plate firmly adhering to the substratum singly or in small groups. Also the rare, small tylostyles with a sinuous shaft and a typical mushroom-like head were never recorded in the Western Mediterranean and Atlantic species of the genus. The phylogenetic reconstruction using maximum likelihood (ML) and Bayesian Inference (BI) analyses (COI, 18S rRNA, and 28S rRNA) recovered a robustly supported sister relationship between the Mediterranean P. mereui sp. nov. and Protosuberites sp. ‘Panama’ from the Eastern Pacific Ocean. The genetic distances based on COI sequences between all compared Protosuberites species were always higher than 2%, a value sufficient to confirm that P. mereui sp. nov. is a distinct species within the genus. Morphological and genetic analyses confirm unanimously P. mereui sp. nov. as a new species. Our results contribute to the assessment of biodiversity in anchialine/estuarine caves and increase data on sponge adaptive strategies in these extreme ecosystems.

The genus Pediella Roberts, described originally from the Venezuelan Páramos is reviewed. Three new species from the Peruvian Puna are described. The genus shows a striking disjunct distribution. It is the only Melanoplinae genus known to occur at the Páramos and Puna highlands above 3000 meters. Pediella exhibits a homogeneous morphology across species. Differences among species are rather small, observed mostly in the shape of the male cerci, phallic complex, and coloration of the hind tibiae. The edition of this paper has been formatted with embedded links to images of type specimens, maps based on geo referenced specimen data and species key available on the Orthoptera Species file online (http://orthoptera.speciesfile.org).

Three new species of ghost moth, Oxycanus ephemerous sp. nov., O. flavoplumosus sp. nov., and O. petalous sp. nov. are described from South Australia, New South Wales, and south-west Western Australia, respectively. We illustrate these species and compare morphological and molecular (mtDNA COI gene) characters with similar Oxycanus Walker, 1856 species from Australia. Comparative images of Oxycanus subvaria (Walker, 1856), O. byrsa (Pfitzner, 1933), and O. determinata (Walker, 1856) are figured. The type material of the three new species are held in the Australian National Insect Collection, Canberra, the Western Australian Museum, Perth, and in the South Australian Museum, Adelaide. The type specimens of Oxycanus hildae Tindale, 1964 syn. n. were also examined and the taxon is here considered synonymous with O. subvaria. Concerns are raised about the conservation status of all three new species due to few or localised distribution records.

The generic status of Winitia Chaowasku (Annonaceae Juss., Miliuseae Hook.f. & Thomson) is reaffirmed by an extensive phylogenetic reconstruction using seven plastome regions (matK, ndhF, rbcL, ycf1 exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers) and including, among others, seven accessions of Winitia plus two accessions of its sister group, Stelechocarpus Hook.f. & Thomson. The results disclosed a maximally supported clade of Winitia, as well as of Stelechocarpus. The sister relationship of the two genera is still rather poorly supported and the branch uniting them is very short, whereas the branches leading to Winitia and to Stelechocarpus are relatively long, corresponding to their considerable morphological differences. Additionally, in Miliuseae there is a particular indel of eight continuous base pairs in the trnL-trnF intergenic spacer potentially diagnostic for generic discrimination, i.e., members in the same genus possess the same indel structure (absence or presence of a gap), and this indel differentiates Winitia from Stelechocarpus. Winitia cauliflora (Scheff.) Chaowasku appears polyphyletic and Winitia longipes (Craib) Chaowasku & Aongyong comb. nov. based on Stelechocarpus longipes Craib is consequently proposed. Furthermore, our phylogenetic data support a new species, Winitia thailandana Chaowasku & Aongyong sp. nov. from southern Thailand, which is described and illustrated. A key to genera in the sageraeoid clade (Sageraea-Winitia-Stelechocarpus) and a key to the four species of Winitia are provided.

During fungal surveys between 2012 and 2014 in pine-dominated forests of the western Himalayas in Pakistan, several collections of Pseudosperma (Agaricales, Inocybaceae) were made. These were documented, based on morphological and molecular data. During this work, three new species came to light, which are here formally described as Pseudosperma brunneoumbonatum, P. pinophilum and P. triacicularis. These species belong in the genus Pseudosperma fideMatheny et al. (2019) = Pseudosperma clade fideMatheny (2005) = Inocybe sect. Rimosae s.s. fideLarsson et al. (2009). Macro- and micro-morphological descriptions, illustrations and molecular phylogenetic reconstructions of the studied taxa are provided. The new species are differentiated from their close relatives by basidiospore size and colouration of basidiomata. Molecular phylogenetic relationships are inferred using ITS (ITS1–5.8S–ITS2), nrLSU and mtSSU sequence data. All three newly-described taxa likely share an ectomycorrhizal association with trees in the genus Pinus. In addition, five names are recombined in Inosperma, Mallocybe and Pseudosperma. These are Inosperma vinaceobrunneum, Mallocybe erratum, Pseudosperma alboflavellum, Pseudosperma friabile and Pseudosperma neglectum.
