The status of Thamnobryum angustifolium (Holt) Crundw.

Abstract

Morphological distinctions between Thamnobryum alopecurum and T. angustifoliumare maintained when the species are grown under standardized conditions, confirming the validity of the present taxonomic separation of the two species. The record from Madeira is erroneous, so T. angustifolium retains its status as a British endemic.     

Thamnobryum cataractarum,a new species from Yorkshire,with observations on T. angustifolium and T. fernandesii

Abstract

Thamnobryum cataractarum sp. nov. is described from Yorkshire, England. It is most closely related to T. fernandesii from Madeira and is also similar to T. angustifolium from Derbyshire, England. The three species are compared, and the habitat of the new species is described. T. fernandesii and T. cataractarum are retained in Thamnobryum rather than in Crassiphyllum Ochyra.     

Thamnobryum subserratum and T. subseriatum (Musci) in Asia

A review of the nomenclatural history ofThamnobryum subserratum andThamnobryum subseriatum shows that the former, which ranges widely from the Himalayas to Southeast Asia, has been misrepresented in the literature asThamnobryum “subseriatum,” and that the latter, which appears to be a Japanese endemic, has been called a superfluous name,Thamnobryum sandei. A new combination,Thamnobryum subseriatum (Mitt. ex Sande Lac.) Tan, is proposed for the Japanese endemic and its lectotype hereby designated. In addition, morphological differences between the two taxa are discussed.     

Notes on the genus Thamnobryum in Macaronesia (excluding the Cape Verde Islands)

Abstract

The genus Thamnobryum is reviewed from Macaronesia (excludingthe Cape Verde Islands). In this area there are three species, T. alopecurum (Hedw.) Gang., T. maderense (Kindb.) Hedenäs, comb. nov. and T. fernandesii C. Sérgio. T. fernandesii is only known from Madeira; the other two also occur on the Canary Islands and the Azores. Thamnobryum canariense (Ren. & Card.) Long is transferred to Isothecium, as I. atlanticum Hedenäs, comb. et nom. nov.     

Obituaries

Abstract

The history and nomenclatural problems of the name Limbella are reviewed, the correct citation of the generic name being Limbella (C. Muell.) Broth. The genus consists of two species, L. tricostata (Sull.) Broth. and L. fryei (R. S. Williams) Ochyra which are described. L. tricostata is endemic to the Hawaiian Islands and L. fryei to Oregon on the Pacific coast of North America. Sporophytes are recorded for the first time in L. tricostata. The family relationships of Limbella are discussed and it is placed in the Thamnobryaceae, close to Thamnobryum.     

Revision of the genus Thermistis Pascoe 1867, with descriptions of three new species (Coleoptera: Cerambycidae: Lamiinae: Saperdini)

The genus Thermistis Pascoe 1867 is revised. T. croceocincta conjunctesignata Rondon & Breuning 1971 is upgraded to a species and newly recorded from China and Myanmar. T. xanthomelas Holzschuh 2007 is newly recorded from Vietnam, Laos and Myanmar. T. sulphureonotata Pu 1984 is newly recorded from Vietnam and Laos. Three new species are described from China: T. hainanensis Lin & Yang n. sp. from Hainan Island, T. kaiyuni Chou & Kurihara n. sp. from Taiwan Island and T. cheni Lin & Chou n. sp. from Yunnan and Sichuan provinces. Photographs of habitus and terminalia and a key to the eleven valid species of Thermistis are presented.     

Descriptions,transferences and synonymies in American Monochamini (Coleoptera,Cerambycidae, Lamiinae), with revised keys to species of Hammatoderus and Taeniotes

Hammatoderus wappesi n. sp. and H. garciaorum n. sp. are described from Mexico, Veracruz and Oaxaca and Veracruz, respectively. Hammoderus brasiliensis Breuning, 1943 and Plagiohammus camillus Dillon & Dillon, 1949 are proposed as synonyms of Hammatoderus confusor (Dillon & Dillon, 1941); Plagiohammus rotundipennis Breuning, 1950 is proposed as a synonym of Hammatoderus pollinosus (Bates, 1880). A replacement name, Deliathis neonivea nom. nov., for Deliathis nivea (Breuning, 1943) n. comb., a secondary homonym of D. nivea Bates, 1869, is proposed. Three other new combinations are proposed: Deliathis imperatrix (Thomson, 1868) n. comb.; Monochamus sargi (Bates, 1885) n. comb.; and Monochamus blairi (Breuning, 1936) n. comb. Monochamus sargi and Hammatoderus pollinosus are redescribed. Hammatoderus sticticus (Bates, 1874) is newly recorded from Bolivia, with H. confusor newly recorded from Argentina and Colombia and its known distribution in Brazil expanded to include the state of Sao Paulo. Distribution of Deliathis imperatrix in Mexico is expanded to include the state of Morelos. A key to species of Hammatoderus and a key to species of Taeniotes “amazonum” group are also provided.     

A contribution to the taxonomy of Piptadenia (Mimosaceae) in South America

Four new species ofPiptadenia are described:P. anolidurus (from Amazonian Ecuador, Peru and Brazil),P. buchtienii (from trans-Andean Bolivia),P. cuzcoënsis (from southern Peru), andP. imatacae (from Venezuelan Guayana); andP. adiantoides var.peruviana J. F. Macbr. is raised in rank toP. peruviana. In relation toP. imatacae the transfer ofP. uaupensis Benth. andP. floribunda Kleinhoonte toAdenopodia Presl is shown to be ill-advised. The affinities of each new species are discussed and critical characters are illustrated.Mimosa tessmanii Harms is newly synonymized withP. uaupensis.

     

A preliminary list of the Muscidae (Diptera) of the Magadan region,Russia

A preliminary list is given of the species of the Muscidae (Diptera) of the Magadan region, including 93 species in 23 genera. Eighty-one species are newly recorded from this territory. Six species [Spilogona aenea Huckett, 1965, S. bifimbriata Huckett, 1965, S. fulvibasis Huckett, 1965, S. incerta Huckett, 1965, S. separata Huckett, 1965, S. trigonifera (Zetterstedt, 1838)] are newly recorded for Russia. All these species, except Spilogona trigonifera, are newly recorded for the Palaearctic region. The species list includes the material examined, ecological data of some species, the distribution and all known references to each species. According to preliminary estimates, this list reflects 60% of expected species in the Magadan region. Two new synonyms are proposed: Coenosia shumshuensis Shinonaga & Zhang, 2000, n. syn. for C. alaskensis Huckett, 1965, and Coenosia remissa Huckett, 1965, n. syn. for C. ciliata Hennig 1961.     

A revision of the Chinese Catops Paykull 1798 of the Catops fuscus species group (Coleoptera: Leiodidae: Cholevinae)

Five species of the Catops fuscus species group are reported from China. Three species are newly described: C. hlisnikovskyi n. sp. from the Beijing municipality and Jiangsu province, C. schuelkei n. sp. from Sichuan and Yunnan provinces, and C. smetanai n. sp. from Sichuan and Yunnan provinces. Female of C. sasajii Nishikawa 2007 is described and the species is reported from Hubei, Sichuan and Yunnan provinces for the first time. Catops nigricans (Spence 1813) is reported for the first time from China (Xinjiang Uygur autonomous region). Important morphological characters are illustrated and the distribution of all species in China is mapped. Preliminar phylogenetic analysis separates (C. hlisnikovskyi n. sp.+C. fuscus fuscus Panzer 1794) as a sister clade to C. nigricans+(C. sasajii+(C. schuelkei n. sp.+C. smetanai n. sp.)), with C. paramericanus Peck & Cook 2002 as outgroup.

Summary

The differences between Anisopodus White, 1853 and Hyperplatys Haldeman, 1847 are discussed and the gender of the latter is corrected. Notes on Hyperplatys pusillus (Bates, 1863) are provided. Hyperplatys nigrisparsus is considered a new rank for H. pusillus nigrisparsus (Bates, 1885). This species is newly recorded from Brazil (Amazonas). Alcidion laetulum Bates, 1880 (currently Nealcidion laetulum), Alcidion costatum Monné & Martins, 1976 (currently Nealcidion costatum), and Nealcidion murinum Monné, 1998, are synonymized with Alcidion bispinum Bates, 1863 (currently Nealcidion bispinum). Anisopodus melzeri Gilmour, 1965 is transferred to Hyperplatys with a new record from the Brazilian state of Mato Grosso do Sul. Notes on a second specimen of Confluentia colombiana (Gilmour, 1950) are provided. Three new species are described from Ecuador: Nealcidion kayi n. sp. (Acanthocinini), Hyperplatys pichinchensis n. sp. (Acanthocinini) and Confluentia quijos n. sp. (Colobotheini).     

Diversity and ecology of the bryophytes in the cave environment: a study on the volcanic and karstic caves of Sicily

The results of a long investigation (20 years) on bryophyte diversity of 28 Sicilian caves are reported; the study regarded both karstic and volcanic caves, located at altitudes ranging from 15 to 2030 m a.s.l. The bryophyte diversity consists of a total of 136 taxa, 20 liverworts, 3 hornworts and 113 mosses. The ecological analysis was performed using the Ellenberg indicator values for moisture, light and soil reaction to the substrate. On the whole, mesophytic and meso-hygrophytic, sciophytic and photo-sciophytic species strongly prevail independently from the geological nature of the caves; the values of the soil reaction to the substrate well reflect the characteristics of the substrate. The phytogeographical analysis shows the prevalence of the Mediterranean species, followed by the temperate and southern-temperate species. It is remarkable the occurrence of boreo-arctic-montane species, which find refuge for their survival in some high-altitude caves. Some typical species well adapted to the cave environment are reported, including Amphidium mougeotii, Isopterygiopsis pulchella, Thamnobryum alopecurum and Rhynchostegiella tenella, showing a troglophilous character. The occurrence of species of phytogeographical significance, as well as of conservation interest, e.g. Ptychostomum cernuum, Tortula bolanderi, Rhabdoweisia fugax, Grimmia torquata, Brachytheciastrum collinum, very rare in Italy, is emphasized too.     

Compositae of the Guayana Highland—XIII. New combinations in Conyza (Astereae), Praxelis (Eupatorieae), and Riencourtia (Heliantheae) based on names proposed by L.C.M. Richard

The new combinations Conyza laevigata (Astereae), Praxelis diffusa (Eupatorieae), and Riencourtia pedunculosa (Heliantheae) are made. Conyza laevigata includes C. apurensis; Praxelis diffusa includes P. pauciflora and the type of the genus, P. villosa; and Riencourtia pedunculosa includes R. glomerata and R. spiculifera, the type of the genus. Lectotypes are designated for names of five species described by Richard. The current names of other species of Compositae described by Richard in 1792 are given, including the reduction of Eupatorium incisum to Chromolaena odorata. Labeling errors are discussed, and the type of Erigeron laevigatus is taken to be from the West Indies. Riencourtia is newly documented for Bolivia and Panama.     

Isotomiella (Isotomidae: Collembola) of China

The relationships between this species and F. calva (Hackel) Richter from the Julian Alps are discussed and the diacritic characters are newly defined.     

Revision of the genera Nemotha Wood-Mason, 1884 and Tricondylomimus Chopard, 1930 stat. rev., with description of a new species (Dictyoptera: Mantodea)

The oriental species previously included in the rarely collected genus Nemotha Wood-Mason, 1884 (Mantodea: Iridopterygidae) are revised. N. coomani (Chopard, 1930) and N. mirabilis Beier, 1933 strongly differ from the type species N. metallica (Westwood, 1845) by family-level morphological features, but share a unique type of forefemoral armament with the genera Hapalopeza Stål, 1877 and Amantis Giglio-Tos, 1915, suggesting Nemotha is of a polyphyletic nature. The genus Tricondylomimus Chopard, 1930 is resurrected from synonymy to accommodate T. coomani, T. mirabilis n. comb. and the species which is newly described in this article, T. intermedius n. sp. The monotypic genus Pseudogousa Tinkham, 1937 and its species P. sinensis Tinkham, 1937 are synonymized with Tricondylomimus and T. mirabilis, respectively. The genus Tricondylomimus is placed in Iridopterygidae, while Nemotha is transferred to Hymenopodidae: Anaxarchini.
