Although Eugenia and Plinia genera belong to different subtribes in Myrteae (Myrtaceae), shared morphological features have led to frequent mistaken identity to these species. Molecular phylogeny and morphological studies in Plinia show that Plinia martinellii and Plinia sebastianopolitana should be combined within the generic concept of Eugenia. In addition, two synonymizations under Plinia sebastianopolitana and one under Plinia martinellii are proposed. Commentary on these nnomenclatural adjustments, as well as on morphological and geographical data related to the evolution of these lineages is also provided.

High Species Diversity

Owing to the high species diversity and the lack of a modern revision, the phylogenetic relationships within the tribe Boarmiini remain largely unexplored. In this study, we reconstruct the first molecular phylogeny of the Palaearctic and Oriental members of Boarmiini, and infer the relationships among tribes within the ‘boarmiine’ lineage. One mitochondrial (COI) and four nuclear (EF-1α, CAD, RpS5, GAPDH) genes for 56 genera and 96 species of Boarmiini mostly from the Palaearctic and Oriental regions were included in the study. Analyses of Bayesian inference and maximum likelihood recovered largely congruent results. The monophyly of Boarmiini is supported by our results. Seven clades and seven subclades within Boarmiini were found. The molecular results coupled with morphological studies suggested the synonymisation of Zanclopera Warren, 1894, syn. nov. with Krananda Moore, 1868. The following new combinations are proposed: Krananda straminearia (Leech, 1897) (comb. nov.), Krananda falcata (Warren, 1894) (comb. nov.), and Krananda fulva (Yazaki, 1994) (comb. nov.). Our results also supported the monophyly of the ‘boarmiine’ lineage. Boarmiini were recovered as sister to the remaining taxa within the ‘boarmiine’ lineage, and Macariini were recovered as sister to Abraxini, Eutoeini and Cassymini.

Clade 1

Many phenotypical features traditionally used to classify genera in Parmeliaceae and in lichens in general have evolved several times independently, potentially limiting their taxonomic utility. Here, we aim to elucidate evolutionary relationships of Canoparmelia s. lat. among other parmotremoid taxa. A multilocus dataset (ITS, nuLSU and mtSSU rDNA sequences) was gathered and analyzed within a phylogenetic framework. Canoparmelia s. lat. was recovered as highly polyphyletic within the parmelioid clade, and three divergent lineages representing Canoparmelia s. lat. were identified in addition to the previously segregated Crespoa group. Of these, two formed a sister relationship with Parmotrema. However, no apparent diagnostic morphological features were found distinguishing the distinct Canoparmelia s. lat. clades reconstructed in the phylogenetic analyses. As a consequence, we propose to restrict the circumscription of Canoparmelia to clade 1 (i.e. the C. texana group) and to include clades 2 and 3 in Parmotrema. We propose to recognize these well-supported monophyletic clades at subgeneric level. Consequently, the new subgeneric name Parmotrema subgen. Africanae is proposed for clade 3 recovered in this study. Since clade 4, which clusters with the genera Nesolechia and Punctelia, is only represented by a single sequenced specimen, we refrain from proposing any taxonomic changes. The new combinations Parmotrema epileucum, and P. zimbabwense are proposed.

The genus Cryphocricos Signoret, 1850 was recently determined in a molecular phylogeny to be distantly related to other taxa of the subfamily Cryphocricinae to the extent that it is now once again the sole member of the subfamily. This exclusively New World group of aquatic bugs lives in fast and usually turbulent current and respires by means of a plastron. Efforts to identify morphological features to distinguish among the species have largely fallen short, and some species have been established based on features that exhibit a high degree of intraspecific variation overlapping those of other species. Presented here is a review of the 13 described species with discussions of their features and photos of type specimens, and three new species from Venezuela and Colombia are described. Also presented is a diagnostic attribute unique to the enigmatic Cryphocricos barozzii Signoret, 1850.

Combined Matrix

Seven genera new to science, i.e.: Helmutiopsis, Huriopsis, Johnsheardia, Klauskalbia, Kudratovia, Kurokawia and Poeltonia of the Physciaceae are proposed for the ‘Rinodina’ atrocinerea, the ‘Rinodina’ xanthophaea, the ‘Rinodina’ cinnamomea, the ‘Heterodermia’ obscurata, the ‘Rinodina’ straussii, the ‘Anaptychia’ isidiata and the ‘Physconia’ grisea groups consequently that all form strongly supported monophyletic branches in a phylogeny analysis based on a combined matrix of nrITS and mtSSU sequences. Phylogenetic positions of species belonging to the genera Kashiwadia s. l., Leucodermia, Mischoblastia,Oxnerella, Phaeorrhiza s. l., Polyblastidium and Rinodinella s. l. are discussed. Oxnerella afghanica which for the first time recorded as parasitic lichen species from both epiphytic and saxicolous crustose lichens is designated as type species for the genus Oxnerella. Sequences of the recently described Physcia orientostellaris as well as Huriopsis xanthophaea and additional sequences of Kashiwadia aff. orientalis and Mischoblastia aff. oxydata are submitted to the GenBank. The positions of Polyblastidium casaterrinum from Costa Rica, ‘Rinodina’ efflorescens from Białowieża, Poland, and ‘Mischoblastia’ confragosula from Cambodia in the Physciaceae are confirmed in a phylogeny analysis based on the nrITS sequences. The presence of ‘extraneous mycobiont DNA’ in lichen associations is exemplified with earlier incorrect identifications of Heterodermia, Kashiwadia, Kurokawia,Oxnerella and Poeltonia specimens. Fifty-six new combinations are presented: Helmutiopsis alba (for Rinodina alba Metzler ex Arn.), Helmutiopsis aspersa (for Lecanora aspersa Borrer), Helmutiopsis atrocinerea (for Parmelia atrocinerea Fr.), Huriopsis chrysidiata (for Rinodina chrysidiata Sheard), Huriopsis chrysomelaena (for Rinodina chrysomelaena Tuck.), Huriopsis lepida (for Lecanora lepida Nyl.), Huriopsis luteonigra (for Rinodina luteonigra Zahlbr.), Huriopsis plana (for Rinodina plana H.

Taxonomic Changes

Extant genera and subgenera of the Trogidae (Coleoptera: Scarabaeoidea) are reviewed. Contemporary classifications of this family have been based exclusively on morphological characters. The first molecular phylogeny for the family recently provided strong support for the relationships between morphologically defined genera and subgenera. On the basis of morphological, molecular and biogeographical evidence, certain taxonomic changes to the genus-level classification of the family are now proposed. The family is confirmed as consisting of two subfamilies, Omorginae Nikolajev and Troginae MacLeay, the former with two genera,OmorgusErichson andPolynoncusBurmeister, and the latter with two genera,TroxFabricius andPhoberusMacLeaystat. rev.Phoberusis restored to generic rank to include all Afrotropical (including Madagascan endemic) species;Afromorgusis confirmed at subgeneric rank within the genusOmorgus; and the monotypic Madagascan genusMadagatroxsyn. n.is synonymised withPhoberus.The current synonymies ofPseudotroxRobinson (withTrox),ChesasBurmeister,LagopelusBurmeister andMegalotroxPreudhomme de Borre (all withOmorgus) are all accepted to avoid creating speculative synonyms before definitive phylogenetic evidence is available. New combinations resulting from restoringPhoberusto a monophyletic genus are listed in Appendix A.

Morphological And Molecular Data

Abstract Dacrymycetes has four families and 13 genera, few of them with molecular data available and then usually polyphyletic in phylogenetic analyses. Dacrymyces Nees is one of the polyphyletic genera in Dacrymycetes and it was introduced to accommodate one species, D. stillatus Nees. The morphological features of the genus are a homogeneous composition of the intra-structure and an amphigenous or superior hymenium. In this study, we included Neotropical specimens in the phylogeny of the Dacrymycetes and Dacrymyces s.s. is emended to include species with resupinate basidiomata, unilateral hymenium and heterogeneous context. In this new delimitation, the new species Dacrymyces flavobrunneus is described using morphological and molecular data and three new combinations (D. ceraceus comb. nov., D. maxidorii comb. nov. and D. spathularia comb. nov.) are proposed based on DNA analyses.

Adjectival Inflection

In the evolution of morphological studies, morphological features and markedness have come to play increasingly important rôles. Feature notation in morphology allows the development of the notion of natural morphological class, renders explicit much of the internal structure of paradigms and permits the exploitation, suitably adapted, of many of the results obtained in phonology. Markedness considerations, particularly when linked to general theories of morphology, again highlight morphological structure, constrain the variety of permitted analyses, and indicate, at least in part, the expected direction of historical change. In the sections to follow, I will present an analysis of Old French nominal and adjectival inflection which makes key use of morphological features and the differences between the marked and unmarked values of these features. This study will be particularly concerned with constraining the morphological analysis of Old French and conversely, with using Old French data to investigate more general properties of morphological systems.

Pharyngeal Apparatus

The main character distinguishing Minibiotus from Macrobiotus is the presence of peribuccal papulae instead of lamellae. However, most Minibiotus species also share a set of characters of the bucco-pharyngeal apparatus. This set is defined by ten morphological features (the first seven common to all species, the last three to most of them): antero-ventral mouth (1), teeth in oral cavity absent or strongly reduced (2), a rigid and narrow buccal tube (3), buccal tube wall thickened below the point of insertion of stylet supports (4), stylet supports inserted at considerable distance from the posterior end of the buccal tube (5), short ventral lamina (6), short macroplacoid row length (7), a double curvature of the buccal tube (8), first macroplacoid situated very close to the pharyngeal apophysis (9) and three almost rounded macroplacoids (10). We examined the original descriptions and/or the type material of several species belonging to the genus Macrobiotus that seemed to present this set of characters. It was concluded that several species should be transferred from Macrobiotus to Minibiotus. The following new combinations are proposed: Minibiotus subintermedius (Ramazzotti, 1962) comb. n., Minibiotus pustulatus (Ramazzotti, 1959) comb. n., Minibiotus julietae (de Barros, 1942) comb. n., Minibiotus marcusi (de Barros, 1942) comb. n., Minibiotus granatai (Pardi, 1941) comb. n., Minibiotus allani (Murray, 1913) comb. n., Minibiotus crassidens (Murray, 1907) comb. n. and Minibiotus acontistus (de Barros, 1942) comb. n.. As a result of these new combinations, the genera Minibiotus and Macrobiotus appear to be more homogeneous, but their monophyly has not yet been demonstrated. Further data are necessary to better analyze the systematic position of Macrobiotus lazzaroi Maucci, 1986, Macrobiotus spertii Ramazzotti, 1957 and Macrobiotus striatus Mihelčič, 1949.

All available phylogenetic evidence indicates that the rattan genus Calamus, the largest of all palm (Arecaceae) genera, is non-monophyletic and that the four remaining genera of subtribe Calaminae (Calameae: Calamoideae), Ceratolobus, Daemonorops, Pogonotium and Retispatha, are nested within it. This issue has not yet been adequately addressed in palm classifications, with recent authors preferring to wait for further phylogenetic evidence before revising the limits of the genera. Here, an alternative solution is proposed that is both pragmatic and phylogenetically robust. An expanded Calamus is recognised into which Ceratolobus, Daemonorops, Pogonotium and Retispatha are subsumed. This broad generic concept, which includes ca. 520 species, has practical advantages as it is more clearly defined by morphological and anatomical characters, and resolves potential biases introduced to recent eco-evolutionary research on palms by the non-monophyly of critical genera. Future phylogenetic research may yet provide an alternative means of delimiting these genera, but the broad sense Calamus proposed here is a justifiable alternative that can be adopted immediately. Nomenclatural synopses transferring currently accepted species of Ceratolobus, Daemonorops and Pogonotium to Calamus are provided, including 70 new combinations and 12 replacement names.
