The new leafhopper genus Vittalianareticulata gen. nov., sp. nov., is described from India, and placed in the tribe Opsiini based on ocelli close to eyes, without carina on anterior margin of the face and bifurcate aedeagus with two gonopores. Phylogenetic analysis with maximum likelihood (ML) using IQtree v1.4.1 of combined data (Histone H3 and 28S rDNA) reveals that the new genus Vittaliana belongs to a clade consisting of Opsius versicolor (Distant, 1908), Opsiini gen. sp., Libengaia sp., Hishimonus phycitis (Distant, 1908) and Yinfomibus menglaensis Du, Liang & Dai (2019) with good branch support, and that the tribe Opsiini is paraphyletic. This resolves the placement of a new genus in the tribe Opsiini under Deltocephalinae.

A new genus of Neotropical Lycidae, Currhaeus gen. nov., is herein proposed as the second Eurrhacini genus lacking parameres in male genitalia. Seven new species are described: Currhaeus striatus sp. nov., C. nigroapicalis sp. nov., C. championi sp. nov., C. tabascensis sp. nov., C. ruschii sp. nov., C. polegattoi sp. nov., and C. paranaensis sp. nov. Illustrations of diagnostic characters and a key to species identification are presented. Parsimony and maximum likelihood analyses of morphological data demonstrated that Currhaeus gen. nov. belongs in the crown Eurrhacini. Implied weighting parsimony trees recovered Currhaeus as sister to Eurrhacus Waterhouse.

A new genus of long-horned chasmosaurine ceratopsid is described from the Dinosaur Park Formation (upper Campanian) of Western Canada. Mojoceratops perifania is represented by a skull and a parietal from the Dinosaur Park Formation of Alberta and an isolated parietal from the Dinosaur Park Formation of Saskatchewan. Several other specimens are provisionally referred to this taxon. While Mojoceratops shares many plesiomorphies with Chasmosaurus, the animal lacks the forward-curving parietal epoccipitals and reduced postorbital horns that diagnose the genus Chasmosaurus, and it differs from all other chasmosaurines in exhibiting a prominent sulcus on the anterior margin of the parietal, swellings on the anterodorsal surface of the parietal rami, and a small accessory process on the first parietal epoccipital. Other unusual features include anteriorly extended parietal fenestrae, a broad, heart-shaped frill, and transverse expansion of the postfrontal fontanelle. The type material of “Eoceratops canadensis” and “Chasmosaurus kaiseni” are nondiagnostic and these names are therefore considered nomina dubia, but their morphology is consistent with Mojoceratops and they probably belong to this genus. The frill of Mojoceratops shows marked variation. Some of this variation probably results from intraspecific variation or ontogenetic changes, but because the Dinosaur Park Formation encompasses more than a million years of time, evolution may explain some of these differences. Phylogenetic analysis shows that Mojoceratops forms a clade with Agujaceratops mariscalensis; Chasmosaurus is the most basal member of Chasmosaurinae.

Ibyacerina caparao new genus, new species (Trichoptera: Leptoceridae) is described and illustrated from specimens collected at Serra do Caparaó, Minas Gerais, Brazil. The monotypic genus is characterized by tibial spur formula 0,2,2; preanal appendages originating from a single base with a median process; tergum X broad, heavily sclerotized, saddle-like, wider at apex, and upturned, bearing small stout setae; inferior appendages each 3-branched, setose; and phallic apparatus tubular, curved slightly ventrad, with pair of lateral processes. Phylogenetic Bayesian and maximum likelihood analyses based on concatenated cytochrome oxidase I (COI) and carbamoyl-phosphate synthetase (CAD) partial sequences (1,504 bp) including representatives of 38 leptocerid genera positioned Ibyacerina gen. nov. with good support within Leptocerinae. However, due to low branch support of most relationships among genera within the clade of Leptocerinae, except Mystacidini, Setodini, and Leptocerini, its close affinities and tribal placement are still unknown.

The butterfly tribe Baorini Doherty, 1886 is a large group of skippers. In this study, a total of 8 genera and 41 species of putative members of this tribe, which represent most of the generic diversity and nearly all the species diversity of the group in China, were sequenced for two mitochondrial genes and three nuclear genes (2084 bp). Phylogenetic relationships and subdivision of this tribe were investigated and the status of the genera are discussed. Partitioned maximum likelihood analyses were performed based on the combined dataset. Our results suggest that the data are split into two well-supported clades in the phylogeny tree. This analysis also represents the most complete phylogenetic analysis of the tribe Baorini in China to date, and includes several genera and species that have been previously excluded from published phylogenies of this group.

The systematics of the dipteran family Sciaridae is based mainly on morphological characters and has remained quite controversial. In this study, we used two mitochondrial DNA markers (CO1, 16S) and a nuclear one (28S) to take a glimpse into phylogenetic relationships of part of the North and Central European Sciaridae. A total of 91 species from 19 genera were analysed using Maximum Likelihood based phylogenetics (depending on the availability of valid sequences, 50–70 per gene). We strengthen the suggestion of the Chaetosciara group as an independent subfamily. Within the subfamily Megalosphyinae, two separate Bradysia clades were identified, suggesting a close relation between the genera Zygoneura, Austrosciara, and Scatopsciara. The genus Alpinosciara gen. n. is established to place the species of the former Corynoptera crassistylata group inside the subfamily Megalosphyinae. This new genus now includes 22 species.

Three new species of Entoloma belonging to the subgenus Nolanea, E. brunneoumbonatum, E. luteodiscum and E. brunneoapplanatum, are described from Kerala State, India based on morphology and molecular phylogeny. Comprehensive descriptions, photographs, and comparisons with phenetically similar and phylogenetically related species are discussed. The nuclear ribosomal internal transcribed spacer region (ITS) of the three species was sequenced and analyzed. The ITS-based phylogenetic analysis, performed using Maximum Likelihood (ML) method, supported both the novelty of these species and their infrageneric placement within the subgenus Nolanea. A key to the ten species of Entoloma subgenus Nolanea known from India is also provided.

Didymosphaeria spartii was collected from dead branches of Spartium junceum in Italy. Multi-gene phylogenetic analyses of ITS, 18S and 28S nrDNA sequence data were carried out using maximum likelihood and Bayesian analysis. The resulting phylogenetic trees showed this to be a new genus in a well-supported clade in Massarinaceae. A new genus Pseudodidymosphaeria is therefore introduced to accommodate this species based on molecular phylogeny and morphology. A illustrated account is provided for the new genus with its asexual morph and the new taxon is compared with Massarina and Didymosphaeria.

Abstract We compared sequences of mitochondrial cytochrome-b and ND5 genes in a phylogenetic analysis of seven species of jacanas, representing all six genera and including the Greater Painted-snipe (Rostratula benghalensis) as an outgroup. When analyzed separately by parsimony and maximum-likelihood bootstrapping, the two genes produced consistent trees, although the ND5 tree was better resolved than the cytochrome-b tree. When combined, the data from the two genes produced a fully resolved tree that was identical to the ND5 tree. This tree had the following form: ((((Irediparra, Microparra), Metopidius), Actophilornis), ((Jacana jacana, J. spinosa), Hydrophasianus)), Rostratula. The phylogeny consists of two major clades that were known to traditional and phylogenetic taxonomists. It also contains sister taxa that are geographically disjunct: the New World Jacana and Asian Hydrophasianus, and the African Microparra and Australian Irediparra. We postulate that this biogeographic pattern results from the extinction of intervening African and Asian taxa, respectively.

Abstract Onychophora, or velvet worms, are a key group for understanding ecdysozoan evolution. It comprises two families: Peripatopsidae, largely of Austral distribution, and Peripatidae, which is circumtropical. The interrelationships between the members of Peripatidae present many taxonomic issues exacerbated in the radiation of the Neotropical species or Neopatida. To understand the phylogeny of Neopatida, and to test the information of such morphological characters, we gathered novel molecular and morphological datasets focusing on Neotropical specimens. Our data were analysed using a combination of parsimony and maximum likelihood for the individual and combined molecular and morphological datasets. An analysis of morphology alone was inconclusive, supporting the notion that morphological characters used in peripatid taxonomy have little power to resolve phylogenetic relationships among higher taxa in Neopatida. However, the analyses of molecular or combined data show a split of the Neotropical species into two clades, which we use to reassign genera. Epiperipatus, as currently understood, is non-monophyletic, because it includes species of monotypic genera. To avoid paraphyly of Epiperipatus, the following new combinations are proposed: Epiperipatus bouvieri (Fuhrmann, 1913), Epiperipatus hitoyensis (Oliveira et al., 2012a), Epiperipatus solorzanoi (Morera-Brenes & Monge-Nájera, 2010) and Epiperipatus sucuriuensis (Oliveira et al., 2015).
