   Two new genera of the leafhopper tribe Erythroneurini, Hamata gen. nov. and Levigata gen. nov., are established based on type species from Yunnan, China: Hamata coralliformis sp. nov. and Levigata arborea sp. nov., respectively. Two additional new species, Gladkara bifi da sp. nov. from Yunnan and Thapaia tibetensis sp. nov. from Tibet, are described and illustrated and amended descriptions of their respective genera are provided. A new synonymy is suggested: Elbelus tripunctatus Mahmood, 1967 = Elbelus melianus Kuoh, 1992, syn. nov. Eleven species of nine erythroneurine genera are newly recorded from China: Arboridia (Arboridia) kakogawana (Matsumura, 1932), A.

3. Phylogenomic re-evaluation of Triaenonychoidea (Opiliones : Laniatores), and systematics of Triaenonychidae, including new families, genera and species

   The Opiliones superfamily Triaenonychoidea currently includes two families, the monogeneric New Zealand–endemic Synthetonychiidae Forster, 1954 and Triaenonychidae Sørensen, 1886, a diverse family distributed mostly throughout the temperate Gondwanan terranes, with ~110 genera and ~500 species and subspecies currently described. Traditionally, Triaenonychidae has been divided into subfamilies diagnosed by very few morphological characters largely derived from the troublesome ‘Roewerian system’ of morphology, and classifications based on this system led to many complications. Recent research within Triaenonychoidea using morphology and traditional multilocus data has shown multiple deeply divergent lineages, non-monophyly of Triaenonychidae, and non-monophyly of subfamilies, necessitating a revision based on phylogenomic data. We used sequence capture of ultraconserved elements across 164 samples to create a 50% taxon occupancy matrix with 704 loci. Using phylogenomic and morphological examinations, we explored family-level relationships within Triaenonychoidea, including describing two new families: (1) Lomanellidae Mendes & Derkarabetian, fam. nov., consisting of Lomanella Pocock, 1903, and a newly described genus Abaddon Derkarabetian & Baker, gen. nov. with one species, A. despoliator Derkarabetian, sp. nov.; and (2) the elevation to family of Buemarinoidae Karaman, 2019, consisting of Buemarinoa Roewer, 1956, Fumontana Shear, 1977, Flavonuncia Lawrence, 1959, and a newly described genus Turonychus Derkarabetian, Prieto & Giribet, gen. nov., with one species, T. fadriquei Derkarabetian, Prieto & Giribet, sp. nov. With our dataset we also explored phylogenomic relationships within Triaenonychidae with an extensive taxon set including samples representing ~80% of the genus-level diversity. Based on our results we (1) discuss systematics of this family including the historical use of subfamilies, (2) reassess morphology in the context of our phylogeny, (3) hypothesise placement for all unsampled genera, (4) highlight lineages most in need of taxonomic revision, and (5) provide an updated species-level checklist. Aside from describing new taxa, our study provides the phylogenomic context necessary for future evolutionary and systematic research across this diverse lineage.ZooBank Registration: urn:lsid:zoobank.org:pub:81683834-98AB-43AA-B25A-C28C6A404F41

4. Phylogeny of the new subfamily Cladodinae: neotenic fireflies from the Neotropics (Coleoptera: Lampyridae)

   Abstract Phylogenetic relationships of Vestini with extensive sampling were inferred using 37 taxa scored for 66 morphological characters. Consistent with recent DNA analyses, Vesta is found to be sister to Photurinae rendering Vestini monotypic. Conversely, our parsimony and model-based analyses robustly support the new subfamily Cladodinae established for Neotropical species of the former Vestini. The cladodine lineage includes Cladodes, Dodacles, Dryptelytra, Ledocas, plus the newly proposed Andecladodes gen. nov. and Brasilocladodes gen. nov. While Ledocas is mostly paraphyletic, Cladodes is polyphyletic and, therefore, Cladodes s.s. is introduced. Further, most trees presented a distinct Nyctocrepis, which is revalidated and includes the subgenus Fenestratocladodes (transferred from Cladodes). Finally, a highly supported crown clade designated as the Dodacles lineage is regularly recovered, splitting into two sister-clades: (1) Dodacles, Brasilocladodes and (2) Dryptelytra, C. proteus, C. solieri and Andecladodes. Four new Andean species are described: Andecladodes cosangensis sp. nov., A. ovalis sp. nov., Dryptelytra pampahermosae sp. nov. and Ledocas pikillactanus sp. nov. To recover the monophyly of genera, the following new combinations are proposed: Brasilocladodes carinatuscomb. nov., Brasilocladodes delalandeicomb. nov., Brasilocladodes illigericomb. nov., Dodacles lateraliscomb. nov. and Dodacles nigercomb. nov. (transferred from Cladodes); Ledocas emissuscomb. nov., Ledocas remixtuscomb. nov. (from Dodacles); Cladodes proteus comb. nov. (from Ledocas) Nyctocrepis malleri comb. nov. and Nyctocrepi stellatacomb. nov. (from Cladodes); and Cladodes cincticolliscomb. nov. and Cladodes melanuruscomb. nov. (from Vesta).

5. Late Cretaceous angiosperm woods from the McRae Formation, south-central New Mexico, USA: Part 2

   https://doi.org/DOI: 10.1086/695503  

   Estrada-Ruiz, E. ; Wheeler, E.A. ; Upchurch, G.R. ; Mack, G.H. ( January 2018 , International Journal of Plant Sciences)

   Premise of research. Over the past 3 decades, angiosperm woods have been reported from the Campanian to the Maastrichtian of southern Laramidia, including Coahuila and Chihuahua, Mexico; Big Bend National Park, Texas; and the San Juan Basin, New Mexico. Recent investigations of the upper Campanian (76.5 to >72.5 Ma) Jose Creek Member of the McRae Formation, south-central New Mexico, indicate an abundance of well-preserved silicified woods, representing one of the most diverse Cretaceous wood floras in the world. In this report, we describe four new angiosperm wood types. Methodology. The fossil woods described here were collected from the upper Campanian of south-central New Mexico, along the northeastern flank of the Caballo Mountains and in the adjacent Cutter Sag, and were studied using thin sections. The potential affinities of these McRae woods were determined by comparison with fossil and extant woods. Pivotal results. The woods reported here comprise one magnoliid and three eudicots with varying levels of comparability to extant taxa. Laurinoxylon rennerae sp. nov. belongs to Lauraceae and has a combination of features found in multiple extant genera variously referred to as Cinnamomeae Nees, Laureae Maout & Decaisne, or Lauroideae Burnett/core Lauraceae. Turneroxylon newmexicoense gen. et sp. nov. is a eudicot with many similarities to Dilleniaceae but differs in having narrower rays. Mcraeoxylon waddellii gen. et sp. nov. has a suite of features seen in several families of Malpighiales, Myrtales, and Oxalidales. McRae angiosperm wood type 1 has a suite of features found in genera of Dilleniales, Ericales, and Malpighiales. Conclusions. All wood types, with the exception of M. waddellii, have minimum axis diameters of 110 cm (12–50 cm), indicating that they represent trees. This reinforces previous evidence for the presence of small to large angiosperm trees in the Jose Creek Member and underscores the importance of woody angiosperms in vegetation of the southern Western Interior during the Campanian-Maastrichtian.
