AbstractLecanora demissa (Körb.) Zahlbr. is a crustose, lobate lichen that produces soredia and conidiomata but no apothecia. Its placement in Lecanora has long been questioned but nothing better has been proposed. We have studied the nuclear rDNA of the ITS regions and the SSU of L. demissa. In an alignment of the ITS regions of several representatives of Lecanora s. lat. it could clearly be shown by a PAUP analysis, using Aspicilia caesiocinerea as outgroup, that L. demissa does not belong to Lecanora. In a PAUP analysis of sequences of the SSU from representatives of the order Lecanorales, using members of Saccharomycetales as outgroup, L. demissa clustered on a well-supported branch with Caloplaca chlorina. In a further analysis of the ITS sequences of L. demissa together with representatives of Caloplaca and Xanthoria using Protoparmelia as outgroup two most parsimonious trees were found. In these trees the L. demissa branch was well within a strongly supported clade with C. cerina, the type species of the genus Caloplaca. The sister taxon to L. demissa in this analysis was C. variabilis. Chemical data and characters of the conidiomata support the affinity with Caloplaca and the new combination C. demissa (Körb.) Arup & Grube is therefore proposed. A lectotype for Imbricaria demissa has been designated. The phylogenetic analysis of several representatives of the genera Caloplaca and Xanthoria suggests that these genera are not monophyletic as presently circumscribed. Two large, monophyletic groups of species could be recognized, one with Xanthoria species mixed with lobate and crustose members of Caloplaca, and one with mainly crustose Caloplaca, including both species with orange or black apothecia.

A characteristic new species Meotipa sahyadri n. sp. with tall and white translucent abdomen in females is described in detail based on morphology of both sexes, based on specimens collected from the Western Ghats of Maharashtra, Gujarat and Goa. The new species has epigynal projection which is known only in Meotipa picturata Simon, 1895, but differs in shape (trifid vs. quadrangular respectively). Males have longest straight embolus exceeding conductor length. Observations of its natural history are provided. Meotipa picturata is newly recorded from Goa, which extends its north-westward distribution from the previously known records from ‘Kodei Kanal’, India (type locality), Ratchasima Province, Thailand and East Kalimantan, Indonesia. A new combination Meotipa andamanensis (Tikader, 1977) n. comb. (=Argyrodes andamanensis) is proposed based on the comparison of description and illustrations provided in the original paper to that of the characters of the type species M.picturata. 242 morphological characters studied in the previous literature and one additional character ‘epigynal projection’ were scored for Meotipa sahyadri n. sp. and Meotipa picturata. These species were obtained monophyletic, placed within Theridiinae as sister to Chrysso cf. nigriceps using parsimony analysis and Bayesian inference.

Lappula sinaica was recently transferred to the monotypic genus Pseudolappula based on phylogenetic studies, while the related species, L. occultata, has remained in the genus Lappula. In this study, morphological, molecular, and palynological evidence supports that L. occultata should be transferred to the genus Pseudolappula. Both L. occultata and P. sinaica share a combination of nutlets features that distinguish them from Lappula: a longer adaxial keel and a linear attachment scar. Phylogenetic analysis based on ITS and trnL-F strongly supports L. occultata as the sister taxon of P. sinaica. In addition, pollen grains of these two species are 3-syncolporate with 3 alternating pseudocolpi, which is significantly different from the grains of Lappula taxa. Based on the above evidence, the new combination Pseudolappula occultata is proposed.

Keys to adults and larvae of the genera of West Palaearctic nematine sawflies are presented. Species of some of the smaller genera are keyed, and their taxonomy, distribution, and host plants reviewed, with a geographic focus on north-western Europe, particularly Sweden. Dinematus Lacourt, 2006 is a new junior subjective synonym of Pristiphora Latreille, 1810, resulting in the new combination Pristiphora krausi (Lacourt, 2006) for the type species of Dinematus. Hemichroa monticola Ermolenko, 1960 is a new junior subjective synonym of Hemichroa australis (Serville, 1823). Lectotypes are designated for Tenthredo opaca Fabricius, 1775, Mesoneura opaca var. nigerrima Enslin, 1914, Mesoneura opaca var. obscuriventris Enslin, 1914, Nematus hypogastricus Hartig, 1837, Nematus alnivorus Hartig, 1840, Leptopus rufipes Förster, 1854, Nematus protensus Förster, 1854, and Platycampus luridiventris var. pleuritica Enslin, 1915. A phylogenetic analysis based on four genes (mitochondrial COI and nuclear NaK, POL2, and TPI) supports the current generic classification.

New Taxon

Xenoceratops foremostensis gen. et. sp. nov., a new centrosaurine ceratopsid from the Foremost Formation (Campanian) of Alberta, is described based on frill material from at least three adult-sized individuals collected from a low-density bone bed. The material can be assigned to Centrosaurinae based on features of the preserved squamosal. Although the parietals are incomplete, the shape of the diagnostic parietal can be inferred from several overlapping serial elements. The parietal of the new taxon shares with all other centrosaurines, except Centrosaurus apertus , spike-like ornamentation at the posterolateral (P3) locus under traditional coding methods. At approximately 78 Ma, it is the oldest known Canadian ceratopsid, approximately 0.5 Ma older than Albertaceratops from the lower Oldman Formation of Canada and approximately 1.0 Ma younger than Diabloceratops from the Wahweap Formation of Utah. A phylogenetic analysis resolves the new taxon as the basalmost centrosaurine and places Centrosaurus brinkmani as the sister taxon to Styracosaurus albertensis . The type species of Centrosaurus brinkmani is moved to a new genus.

Triblidiaceae (Rhytismatales) currently consists of two genera: Triblidium and Huangshania. Triblidium is the type genus and is characterised by melanized apothecia that occur scattered or in small clusters on the substratum, cleistohymenial (opening in the mesohymenial phase), inamyloid thin-walled asci and hyaline muriform ascospores. Before this study, only the type species, Triblidium caliciiforme, had DNA sequences in the NCBI GenBank. In this study, six specimens of Triblidium were collected from China and France and new ITS, mtSSU, LSU and RPB2 sequences were generated. Our molecular phylogenetic analysis and morphological study demonstrated three new species of Triblidium, which are formally described here: T. hubeiense, T. rostriforme and T. yunnanense. Additionally, our results indicated that Huangshania that was considered to be distinct from Triblidium because of its elongated, transversely-septate ascospores, is congeneric with Triblidium. Therefore, we have placed Huangshania in synonymy under Triblidium, rendering Triblidiaceae a monotypic family.

AbstractPatagonicolaPackernew genusis described for two species of xeromelissine bee (Hymenoptera: Colletidae) from Patagonian Argentina. One species,P. graveliPackernew speciesis described; the second species,P. aenigma(Packer)new combination, originally placed inChilicolaSpinola, 1851 subgenusChilioediscelisToro and Moldenke, 1979, is designated as the type species. The new genus is superficially most similar toXenochilicolaToro and Moldenke, 1979 but possesses none of the derived characteristics that were originally used to define that genus. Results of a phylogenetic analysis, based upon 114 morphological characters, are presented and suggest that the new genus is the sister clade to (GeodiscelisMichener and Rozen, 1999 +XeromelissaCockerell, 1926). An illustrated key is provided for the genera of Xeromelissinae and for the two species ofPatagonicola.
