The genus Rhodocodon is here reinstated based on morphological, biogeographical and molecular evidence. On the basis of the work presented by H. Perrier de la Bâthie in Flora of Madagascar, one subgenus and ten species of Rhodocodon are validated here. Furthermore, Rhodocodon madagascariensis and R. urgineoides are lectotypified, and Hyacinthus cryptopodus and Urginea mascarenensis are transferred to Rhodocodon. A complete morphological description for all 13 accepted species of Rhodocodon is provided, including data on biology, ecology and distribution. Furthermore, an identification key for the Rhodocodon species is presented.

ABSTRACT Three species of the Ascomycetes genus Camillea were recorded in a fragment of Amazon rainforest in the region of Santarém, Pará state, Brazil. The occurrence of C. leprieurii, C. cyclops and C. bilabiata expand the range of distribution of these species in the state. Camillea leprieurii has previous records in the regions of Marabá, Oriximiná, Itaituba and Novo Progresso, while C. cyclops had been recorded in the west of the state. This is the first record of C. bilabiata for Pará. We provide a morphological description of the specimens and an identification key for Camillea species found in Pará.

Abstract Thismia is a genus of > 80 mycoheterotrophic species characterized by a peculiar appearance and complex floral morphology. A significant proportion of the species and morphological diversity of Thismia has only been uncovered in the past two decades, and new discoveries continue to be made. Given that many new data have recently become available, and the most comprehensive taxonomic revision of the genus from 1938 addresses less than half of the currently known species, previous hypotheses for species relationships and infrageneric taxonomic classification in Thismia was in need of review. Extensive molecular phylogenetic studies of Thismia at the genus level have never been presented. We investigate the phylogenetic relationships of 41 species (and one variety) of Thismia from the Old World. Our study comprises 68 specimens (for 28 of which the data were newly generated), including outgroup taxa broadly representing Thismiaceae (= Burmanniaceae p.p. sensuAPG IV, 2016), and is based on two nuclear and one mitochondrial marker. We use maximum likelihood and Bayesian inference to infer relationships among the taxa. We also constructed a morphological dataset of 12 mostly floral characters, comparing these characters to hypotheses based on molecular evidence to identify putative synapomorphies for major clades and to discuss hypotheses regarding the evolution of structural traits in the genus. Our analyses indicate that the majority of currently accepted infrageneric taxa of Thismia are polyphyletic. We find support for the monophyly of the Old World group, in which we recognize five well-supported lineages (clades); the only New World species studied appears to be related to the Neotropical genus Tiputinia. Ancestral state reconstructions demonstrate that the evolution of most morphological characters was homoplastic, but we identify characters that provide each of the five clades of Old World Thismia with a unique morphological description. The geographical distribution of the species under study is also shown to be consistent with the major clades. Our investigation provides a phylogenetic basis for the development of a novel sectional classification of Thismia reflecting morphological and geographical traits.

AbstractExamination of 122 specimens ofXanthogrammaSchiner, 1861 (Diptera: Syrphidae) from varied localities in Europe (+Turkey) resulted in the description of two new species (X. aeginaeRicarte, Nedeljković, and Vujićnew speciesandX. pilosumNedeljković, Ricarte, and Vujićnew species), as well as new data on six other species. Most of the examined material originated from the Balkan Peninsula and Greek islands. New species concepts were supported by morphological and molecular evidence. Relationships among the eight studied species were analysed and discussed based on the data of nuclear (ITS2) and mitochondrial (COI) genes sequences. An identification key to the European species ofXanthogrammais provided. Lectotypes are designated forDoros decoratumZetterstedt, 1843,Lasiophthicus novusRondani, 1857,Syrphus laetusFabricius, 1794,Syrphus ornatusMeigen, 1822, andXanthogramma nobilitatumFrey, 1946.

Sequence data generated from the nuclear ribosomal internal transcribed spacer and ribosomal large subunit regions were deposited in GenBank and used to determine phylogenetic relationships within Cortinarius subg. Phlegmacium. A morphological description, illustrations, and phylogeny of the Turkish C. rapaceoides are provided.

A new species of freshwater Amphipod, Gammarus topkarai sp. nov., collected from Ivriz Creek, Tarsus Province, South Anatolia, is described and illustrated. The new species belongs to Gammarus pulex-group and shows similar characteristic features with Gammarus agrarius G. S. Karaman, 1973. Absence of well developed dorsal elevations on the urosome segments, smaller body length and relatively lower endopod/exopod ratio of third uropod are the most obvious features differ from G. agrarius. A detailed morphological description and illustrations of new species are given and differences from related species are discussed. An updated identification key of Gammarus taxa reported from Turkey, up to date, was also presented.

Three new species of Xylaria on fallen leaves in Hainan Province of China are described and illustrated, based on morphological and molecular evidence. Xylaria hedyosmicola is found on fallen leaves of Hedyosmum orientale and featured by thread-like stromata with a long sterile filiform apex. Phylogenetically, X. hedyosmicola is closely related to an undescribed Xylaria sp. from Hawaii Island, USA and morphologically similar to X. vagans. Xylaria lindericola is found on fallen leaves of Lindera robusta and characterised by its subglobose stromata and a long filiform stipe. It is phylogenetically closely related to X. sicula f. major. Xylaria polysporicola is found on fallen leaves of Polyspora hainanensis, it is distinguished by upright or prostrate stromata and ascospores sometimes with a slimy sheath or non-cellular appendages. Xylaria polysporicola is phylogenetically closely related to X. amphithele and X. ficicola. An identification key to the ten species on fallen leaves in China is given.

A new amphipod species, Dikerogammarus istanbulensis sp. nov., is described. Specimens were collected from a reservoir, near Silivri district, İ stanbul province, Turkey. The new species is similar to Dikerogammarus bispinosus Martynov, 1925 except for the presence of setae on inner surface of basal segment of pereopod 7 in both sexes and absence of long setae on the ventral side of second peduncle segment of antenna 1. In addition, epimeral plate 2 has many setae along the ventral margin in both sexes. A detailed morphological description and illustrations of the new species are given. Differences between the new species and related species are discussed. An identification key for the genus Dikerogammarus is presented.

A New Species

A new species of Heteropterys belonging to the Parabanisteria informal group is described for the savannas grasslands of the Serra do Tombador Natural Reserve, municipality of Cavalcante, State of Goiás, Brazil. Heteropterys rosmarinifolia is easily distinguished from the remaining Brazilian species of the Parabanisteria informal group due to its stems unbranched, leaves associated with the inflorescence verticillate, blades linear to very narrowly oblong, strongly conduplicate, ascending to upright, and sparsely sericeous to glabrous at age. We present a complete morphological description for the new species, photographic plates, comments on its distribution, ecology, and taxonomy, besides an identification key to the species of Heteropterys from the Parabanisteria group from the State of Goiás, Brazil.
