We investigated type material of Ulva montana (Lightfoot 1777: 973) and compared it with the type material of Gloeocapsa magma Brébisson in Brébisson & Godey (1835: 40) and fresh material from nature. Our investigation indicates a separate evolutionary lineage of U. montana which possesses specific morphological features differing from the most closely related genera Gloeocapsa, Gloeocapsopsis and Chroococcus. We propose a new genus Lightfootiella gen. nov. based on the new combination Lightfootiella montana comb. nov. We revise the taxonomy of this entity and compare this species with Gloeocapsopsis magma sensu (Brébisson) Komárek & Anagnostidis 1986.

Within the framework of a taxonomic revision of subfamily Urgineoideae, we here describe a new genus from south-eastern South Africa. Sagittanthera gen. nov. is at first sight related to Rhadamanthus and Tenicroa, but it can be clearly differentiated by the presence of bracteoles and the anthers connate to form a cone-like structure dehiscing by minute apical pores. This genus is based on Rhadamanthus cyanelloides, an enigmatic species occurring in the Eastern Cape Province of South Africa. It was described on the basis of incomplete material. Recently, Drimia cremnophila and D. mzimvubuensis, two species that match the diagnostic characters of the new genus, were described from the same region. A complete description is presented for Sagittanthera, and data on morphology, ecology, and distribution are also reported. Two species are accepted in this genus, and the necessary combinations are stated. Furthermore, we demonstrate that pollen is released by vibration. This fact together with morphological features of the androecium clearly evidence that buzz pollination occurs in this new genus.

AbstractBetween 1960 and 1975, 212 names of foliicolous lichenized fungi (or believed to have such a biological status) were described or used by A. C. Batista and co-workers. A considerable number of the new names were not validly published but mentioned as nomina nuda in various papers, while a further 69 names exist only as herbarium names. A taxonomic revision demonstrates that 36 of the 38 validly described genera ( = 95%) and 56 of the 68 validly published species and varieties ( = 82%) are either synonyms of previously known taxa, or represent non-lichenized or lichenicolous fungi, or cannot be readily identified and remain nomina dubia. Most of the descriptions refer to pycnidia, particularly those of the Strigulaceae (5 genera, 8 species or varieties), the hyphophores of Gomphillaceae (6 genera, 10 species), and the genus Microtheliopsis (3 genera, 3 species), whereas campylidia of the Ectolechiaceae are under-represented. A further six, monotypic genera correspond to lichenicolous or non-lichenized fungi. The following validly described taxa remain as autonomous genera or species of foliicolous lichens: Amazonomyces Bat., a generic name taken up for two species previously placed in Stirtonia and Cryptothecia, with two new combinations: Amazonomyces sprucei (R. Sant.) Lücking, Sérus. & Thor comb. nov. [Bas.: Stirtonia sprucei R. Sant.; Syn.: Amazonomyces palmae Bat. & Cavalc], and Amazonomyces farkasiae (Lücking) Lücking, Sérus. & Thor comb. nov. [Bas.: Cryptothecia farkasiae Lücking]; Lyromma Bat. & H. Maia, a distinctive genus of the Dothideales, with two species described by Batista and co-workers, and one new combination: Lyromma palmae (Cavalc. & A. A. Silva) Lücking & Sérus. comb. nov. [Bas.: Anconomyces palmae Cavalc. & A. A. Silva]; Arthonia lecythidicola (Bat. & H. Maia) Lücking & Sérus. comb. nov. [Bas.: Ameropeltomyces lecythidicola Bat. & H. Maia]; Arthonia orbignyae (H. B. P. Upadhyay) Matzer [Bas.: Opegrapha orbignyae H. B. P. Upadhyay; Syn.: Arthonia opegraphina Lücking]; Asterothyrium aspidospermatis (Peres) Lücking & Sérus. comb, nov. [Bas.: Actinoteichus aspidospermatis Peres] and Asterothyrium pernambucense (Cavalc.) Lücking & Sérus. comb. nov. [Bas.: Actinoteichus pernambucensis Cavalc], two apomictic pycnidial forms of Asterothyrium, in addition to the reinstalled A. umbilicatum (Müll. Arg.) Müll. Arg.; Byssoloma guttiferae (Bat. & Peres) Lücking & Sérus. comb. nov. [Bas.: Crocicreomyces guttiferae Bat. & Peres; Syn.: Byssoloma aeruginascens Vězda]; Phyllobathelium leguminosae (Cavalc. & A. A. Silva) Lücking & Sérus. comb. nov. [Bas.: Septoriomyces leguminosae Cavalc. & A. A. Silva]; Tricharia couepiae (Bat.) Lücking & Sérus. comb. nov. [Bas.: Aderkomyces couepiae Bat.] and Trichothelium brasiliense J. L. Bezerra & L. Xavier. Echinoplaca amapensis Bat. & Poroca, a distinctive species with characters that suggest a placement into the Arthoniaceae, will most probably require a new genus when more material is available. One species is validated and two are described as new: Bapalmuia verrucosa Serus. & Lucking spec, nov., Enterographa batistae Lucking & Serus. spec, nov. and Opegrapha ducket Bat., J. L. Bezerra & Cavalc. ex Lucking & Serus.

In order to contribute to the taxonomic revision of several species of Termitomyces, sequences of 74 strains representing 28 taxa were used to generate a combined nLSU-mtSSU phylogenetic tree. The phylogenetic analysis showed that re-classification was required for 12 taxa originally misidentified under various names. The changes led to the use of 8 valid names for these 12 taxa, including two new forms: T. striatus f. subclypeatus and T. medius f. ochraceus; and a new combination: Termitomyces brunneopileatus according to their placement on various clades and subclades in the phylogenetic trees. Termitomyces letestui and T. medius were taxonomically revised. In addition,    T. letestui collected from China is the first record from the Asian continent. This species was so far collected only in tropical Africa. Similarly, T. robustus is reported for the first time from Cameroon. Moreover, the phylogenetic analysis confirms T. subumkowaan as a new species that was originally described only on the basis of morphological features. The combined phylogenetic analysis and morphological features reveal that different strains of the same taxon show sometimes large variations in macro- and micromorphological features, some very likely with links to genetic factors other than genes sequenced here, thereby justifying the new forms erected within these taxa in order to facilitate their identification.

A taxonomic revision of Bouchea Cham. (Duranteae, Verbenaceae) is presented, updating the last formal revision of the genus by Moldenke from 1940, with a more comprehensive and profound study of herbarium material. The analyses of the morphological features support the recognition of 13 Bouchea species. A new combination is proposed for Stachytarpheta bifurca Benth. (≡ B. bifurca (Benth.) P. Moroni & N. O'Leary), and B. boyacana Moldenke var. glabrata Moldenke is elevated to the species rank. Eight taxa are here synonymized: B. inopinata Moldenke (= B. agrestis Schauer), B. prismatica (L.) Kuntze var. brevirostra Grenzeb. (= B. bifurca), B. beckii Moldenke (= B. boliviana (Kuntze) Moldenke), B. flabelliformis M. E. Jones (= B. dissecta S. Watson), B. prismatica var. laciniata Grenzeb. (= B. dissecta), S. kingii Moldenke (= B. nelsonii Grenzeb.), B. boyacana Moldenke (= B. prismatica), and B. spathulata Torr. var. longiflora Moldenke (= B. spathulata). Lectotypes are designated for the names B. incrassata Lange (second-step), B. rusbyi Moldenke (second-step), and S. laxiflora Turcz. Furthermore, B. boliviana is reported for the first time growing in Argentina, B. notabilis Moldenke in Ecuador, and B. rusbyi in Brazil and Peru.

The worldwide distributed family Mactridae Lamarck, 1809, is well represented in the western Atlantic Ocean. An ex-haustive literature research revealed 54 nominal species from the Brazilian coast. The study was done using morphologicalcharacters of shell and in some cases mantle cavity organs. All type material was examined and illustrated. Eleven validliving species are confirmed from the Brazilian littoral and their synonymies and geographic distributions are updated.Redescriptions are provided for Mactrellona alata (Spengler, 1802); Mactrotoma fragilis (Gmelin, 1791); Mulinia clery-ana (d´Orbigny, 1846) and Anatina anatina (Spengler, 1802). The revision of Trinitasia iheringi (Dall, 1897) new combination, reveals the presence of a Tertiary genus among the Recent fauna of South America.

AbstractA taxonomic revision of Hyboserica uncovers an unexpected diversity of species from Southern African forest remnants. The work results in the description of a new genus, Leoserica gen. nov., a new combination, a new synonymy and 32 new species are described. The lectotypes of Serica capensis and Triodonta caffra are designated. The habitus and male genitalia of all revised species are illustrated. A species distribution map and an identification key to the species are provided. Phylogenetic analysis reveals a deep split into one very diverse eastern clade that is distributed north to Zimbabwe, and one western clade that is restricted to the fynbos of the Cape Region.

Discovery of slides bearing type material of Neotonchus punctatus provides a basis for an analysis of the genus Neotonchus Cobb, 1933 and a related new genus, Gomphionema. Characteristics, unique and common to a rich supply of species of these genera, necessitate the erection of a new subfamily within the Cyatholaimidae for the accommodation of the genera. Neotonchus punctatus, the type species, is redescribed and four new species and one new combination are added to the genus, namely N. phaleratus n. sp., N. chamberlaini n. sp., N. lutosa n. sp., N. melotridus n. sp., and N. corcunda (Gerlach, 1956) n. comb. syn. Comesa corcunda. The genus Comesa Gerlach, 1956 is synonymized with Neotonchus Cobb, 1933. The new genus Gomphionema is created for G. typica n. sp. (type species), G. fellator n. sp., and G. compacta (Gerlach, 1957) n. comb. syn. Neotonchus compactus. Keys to, and descriptions of, all species in the subfamily are provided.

A taxonomic revision of Anostomoides is herein presented based on a comprehensive revision of specimens deposited in fish collections and the literature. The present revision proposes that A. laticeps is a junior synonym of A. atrianalis, while A. passionis is a junior synonym of Leporinus nattereri, and the latter is thus transferred to Anostomoides, forming the new combination Anostomoides nattereri. Principal Components Analysis (PCA) showed that examined specimens form two distinct morphotypes, corroborating the validity of both A. atrianalis and A. nattereri. Anostomoides nattereri is distinguished from A. atrianalis by having four branchiostegal rays (vs. three), three pores in infraorbital one (vs. four), 37–39 pored lateral-line scales (vs. 41–44), lower lip with rounded dermal papillae (vs. forming ridges), three dark  rounded midlateral blotches (vs. three or four vertically elongated blotches and/or a faded dark longitudinal stripe), dark lines between scale series on posterior half of body on specimens smaller than 150 mm SL (vs. dark lines absent), a greater body depth (27.6–36.2 % vs. 24.5–38.7% of SL) and smaller interorbital distance (34.4–53.8 % vs. 42.6–67.3 % of HL). Anostomoides nattereri is distributed across several tributaries of the Amazon and Orinoco rivers, whereas A. atrianalis is widespread throughout the Amazon, Orinoco, and Essequibo basins. The genus Anostomoides is currently diagnosed based on a combination of non-exclusive characters: upturned or slightly upturned mouth with four premaxillary teeth including symphyseal tooth bicuspid or with blunt cutting edge, remaining teeth slightly tricuspid (with medial cuspid distinctly larger); four dentary teeth, symphyseal tooth with truncate cutting edge (without cusps); second tooth with a single large cusp, and two lateral teeth with three or slightly more small cusps.
