Devilleferus brunkei Jenkins Shaw & Solodovnikov, gen. et sp. nov., a distinctive new genus and species of Staphylinini rove beetle with an unusual set of morphological characters is described from the tropical Andes (Ecuador and possibly Colombia and Bolivia) in South America. To resolve systematic placement of the new genus within Staphylinini we assembled a dataset of 68 morphological characters scored for 34 taxa representing a broad sample of the respective rove beetle tribe, and performed Bayesian inference and maximum parsimony phylogenetic analyses. Both analytical methods unambiguously placed Devilleferus as sister to the subtribe Amblyopinina, and overall they corroborated recently established subtribal systematics for Staphylinini inferred mainly from molecular markers. Based on the shared synapomorphies, Devilleferus is assigned to the subtribe Amblyopinina. The internal relationships within Amblyopinina remain to be clarified in a broader study of that very poorly explored austral lineage.

Konradus leehermani Chani-Posse & Ramírez-Salamanca, a new genus and species of the subtribe Philonthina (tribe Staphylinini) from the Tropical Andes of Ecuador, is described and illustrated. A dataset of 57 morphological characters scored for 23 taxa representing main clades of Philonthina and its putative sister groups was prepared and analysed by maximum parsimony and Bayesian inference. Both analytical methods unambiguously placed Konradus within the Neotropical (NT) lineage of Philonthina. Phylogenetic relationships of Konradus with other Neotropical representatives are proposed and discussed.

In this paper, Claviformisporagen. nov. in Linocarpaceae is introduced from Phyllostachys heteroclada in Sichuan Province, China. The new genus is characterised by its distinct morphological characters, such as ostiole with periphyses, asci with a thick doughnut-shaped, J- apical ring and clavate ascospore without septum-like band and appendage. Maximum Likelihood and Bayesian Inference phylogenetic analyses, based on DNA sequence data from ITS, LSU, SSU and TEF-1α regions, provide further evidence that the fungus is a distinct genus within this family. The new genus is compared with similar genera, such as Linocarpon and Neolinocarpon. Descriptions, illustrations and notes are provided for the new taxon.

Large Distribution

The superfamily Bogidielloidea is one of the most wide-ranging hypogean amphipod taxa currently known, comprising over 130 species in 43 genera occurring on every continent except Antarctica. This large distribution among such cryptic organisms is curious, especially when combined with weak morphological characters uniting the superfamily. A unique new genus and species of bogidielloid amphipod, Simplexia longicrus, gen. et sp. nov., described from Terrell County, Texas, sheds light on the evolutionary relationships within this grouping. Molecular phylogenetic analyses of the order Amphipoda using two nuclear genes and one mitochondrial gene reveal that this species and the sympatric Parabogidiella americana form a clade removed from other sequenced members of Bogidiellidae sensu stricto, and, as such, the two species are placed in the newly erected Parabogidiellidae, fam. nov. Additional phylogenetic analyses of the cosmopolitan Bogidiellidae are recommended to further resolve its systematics.

The new genus Moquiniastrum, the result of recent phylogenetic analyses, is described. Although these analyses are based on cpDNA and nDNA, they also involve documentation of the distinctive morphological characters supporting this new genus. The recognition of Moquiniastrum is necessary to accurately reflect the relationships of the taxa found in the tribe Gochnatieae. Moquiniastrum includes twenty-one species that are usually gynodioecious and found mainly in Brazil but with some species elsewhere in South America. A description of Moquiniastrum, together with the corresponding new combinations, new lectotypifications of three names and one new neotypification is here provided.

The Family

A fragmentary specimen of pterosaur originally assigned to the genus Pterodaustro Bonaparte, 1970 is reassessed. The presence of a sagittal dorsal cranial crest on a fragment of nasopreorbital arcade with linear vertical trabeculae and the occurrence of alveolar protuberances on the os dentale indicate the new specimen has similarities with crested pterodactyloid pterosaurs of the family Ctenochasmatidae, and with members of the Dsungaripteridae. The presence of alveolar protuberances allows us to assign the specimen to the Dsungaripteridae. It forms the basis of a new genus and species, Domeykodactylus ceciliae.

The generic taxonomy of the Nothofagaceae is revised. We present a new phylogenetic analysis of morphological characters and map these characters onto a recently published phylogenetic tree obtained from DNA sequence data. Results of these and previous analyses strongly support the monophyly of four clades of Nothofagaceae that are currently treated as subgenera of Nothofagus. The four clades of Nothofagaceae are robust and well-supported, with deep stem divergences, have evolutionary equivalence with other genera of Fagales, and can be circumscribed with morphological characters. We argue that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Nothofagus with four subgenera.        Nothofagus is recircumscribed to include five species from southern South America, Lophozonia and Trisyngyne are reinstated, and the new genus Fuscospora is described. Fuscospora and Lophozonia, with six and seven species respectively, occur in New Zealand, southern South America and Australia. Trisyngyne comprises 25 species from New Caledonia, Papua New Guinea and Indonesia. New combinations are provided where necessary in each of these genera.

Labriocimbex sinicus Yan & Wei gen. et sp. nov. of Cimbicidae is described. The new genus is similar to Praia Andre and Trichiosoma Leach. A key to extant Holarctic genera of Cimbicinae is provided. To identify the phylogenetic placement of Cimbicidae, the mitochondrial genome of L. sinicus was annotated and characterized using high-throughput sequencing data. The complete mitochondrial genome of L. sinicus was obtained with a length of 15,405 bp (GenBank: MH136623; SRA: SRR8270383) and a typical set of 37 genes (22 tRNAs, 13 PCGs, and two rRNAs). The results demonstrated that all PCGs were initiated by ATN codon, and ended with TAA or T stop codons. The study reveals that all tRNA genes have a typical clover-leaf secondary structure, except for trnS1. Remarkably, the secondary structures of the rrnS and rrnL of L. sinicus were much different from those of Corynis lateralis. Phylogenetic analyses verified the monophyly and positions of the three Cimbicidae species within the superfamily Tenthredinoidea and demonstrated a relationship as (Tenthredinidae + Cimbicidae) + (Argidae + Pergidae) with strong nodal supports. Furthermore, we found that the generic relationships of Cimbicidae revealed by the phylogenetic analyses based on COI genes agree quite closely with the systematic arrangement of the genera based on the morphological characters. Phylogenetic tree based on two methods shows that L. sinicus is the sister group of Praia with high support values. We suggest that Labriocimbex belongs to the tribe Trichiosomini of Cimbicinae based on adult morphology and molecular data. Besides, we suggest to promote the subgenus Asitrichiosoma to be a valid genus.

Systematic Relationships

Claviplatysgen. n. and its type species C.henryisp. n. (Hemiptera: Heteroptera: Plataspidae: Plataspinae) are described from Kerala, India. The new genus is related to the Indomalayan genera Heterocrates Amyot & Serville, 1843, Cratoplatys Montandon, 1894, and Cronion Bergroth, 1891, but differs from them and all other plataspid genera by the peculiarly modified antenna. The morphological characters and systematic relationships of the above genera are discussed.
