Seven new species of Miliusa (Annonaceae) from Thailand

Seven new species of the genus Miliusa are described from Thailand (M. fragrans, M. hirsuta, M. intermedia, M. nakhonsiana, M. sessilis, M. thailandica, and M. umpangensis). A key to the 19 species of Miliusa in Thailand is provided. In addition, the complete taxonomic nomenclature of all known species of Miliusa in Thailand is given, with several new proposed synonyms. The new as well as the known species of Miliusa in Thailand are classified into four morphological groups on the basis of a combination of flower and/or inflorescence position and inner petal morphology proposed earlier.     

Synopsis of <Emphasis Type="Italic">Mickelia</Emphasis>, a newly recognized genus of bolbitidoid ferns (Dryopteridaceae)

Our recent molecular phylogenetic study revealed a previously unrecognized clade of six species that is sister to Elaphoglossum. Within this clade, four species are currently classified in Bolbitis, one in Lomagramma, and one in Acrostichum. For this clade, we propose the name Mickelia, with M. nicotianifolia as the type species. We also make new combinations for the species in our phylogenetic study shown to belong to Mickelia (M. bernoullii, M. guianensis, M. hemiotis, M. nicotianifolia, M. oligarchica, and M. scandens) and two other species believed to belong to the clade based on morphology (M. lindigii, M. pergamentacea). A new hybrid and two new species are also described (M. ×atrans, M. furcata, and M. pradoi). In total, Mickelia consists of ten species and one hybrid. It is entirely neotropical. We provide a key to the genera of bolbitidoid ferns and a synopsis of Mickelia that gives for each species a complete synonymy, geographical distribution, comparative discussion, and illustration.     

Macrochelid mite fauna in the eastern part of the Lesser Sunda Islands, with description of two new species

Thirteen species in four genera of mites of the family Macrochelidae phoretic on dung beetles were collected in the eastern part of the Lesser Sunda Islands, Indonesia, providing the first record of the family for that area. Of these, two species, Macrocheles entetiensis Hartini and Takaku, sp. nov. and Macrocheles sumbaensis Hartini and Takaku, sp. nov., are new to science. The remaining 11 species are Glyptholaspis fimicola, Holostaspella bifoliata, Macrocheles baliensis, Macrocheles sp. aff. glaber, M. hallidayi, M. kraepelini, M. krantzi, M. limue, M. merdarius, M. oigru and Neopodocinum sinicum.     

A new species of <Emphasis Type="Italic">Mentzelia</Emphasis> section <Emphasis Type="Italic">Bartonia</Emphasis> (Loasaceae) from the Grand Canyon,Arizona

Mentzelia hualapaiensis, a new species of Mentzelia sect. Bartonia, is described from the Grand Canyon region of Arizona. The new species is closely related to M. puberula, which is found west of M. hualapaiensis along the Colorado River, and to M. oreophila, M. polita, and M. tiehmii. It shares with these species a suffrutescent shoot system characterized by a subterranean, branching caudex, multiple annual branches, and similar leaves that have shallowly lobed or toothed to entire laminas. The flowers of M. hualapaiensis differ from those of its closest relatives in having cream-white, linear to narrowly spatulate petals and staminodes, characteristics that are convergent with those of the flowers of the Chihuahuan Desert species M. humilis.     

Mating studies, new species, and new reports of Marasmius from northern Thailand

The mating systems operating in seven species of Marasmius collected recently in northern Thailand were determined. Marasmius cremeus belonging to sect. Sicci subsect. Siccini ser. Leonini, and Marasmius straminiceps belonging to sect. Marasmius subsect. Sicciformes are described as new species. Five members of sect. Marasmius were tetrapolar (bifactorial), viz. M. apatelius, M. guyanensis, M. nigrobrunneus, M. ruforotula, and M. straminiceps. Two members of sect. Sicci were bipolar (unifactorial), viz., M. corneri (syn. M. incarnatus) and M. cremeus. Our data support the hypothesis that the mating system is consistent within infrageneric taxa. The seven species that are herein described, illustrated, and compared with phenetically similar species represent the first reports for this genus in Thailand.     

Myrtlemiris,a new genus and new species of Australian plant bugs (Insecta: Heteroptera: Miridae): systematics,phylogeny and host associations

A new Australian genus of Orthotylinae, Myrtlemiris Cheng, Mututantri & Cassis gen.n. , is described, with nine included species described as new to science (M. agnew sp.n. , M. astartephila sp.n. , M. meanarra sp.n. , M. newmanensis sp.n. , M. rubrocuneatus sp.n. , M. russulatus sp.n. , M. silveirae sp.n. , M. tesselatus sp.n. , M. yalgoo sp.n. ). A phylogenetic analysis based on 39 morphological characters is presented for all Myrtlemiris species and 6 outgroup taxa. This analysis establishes Myrtlemiris as monophyletic, defined by a broad apophysis on the left paramere. A key to species is provided and diagnostic characters are illustrated. Myrtlemiris is endemic to southwest Western Australia. Host plants for Myrtlemiris species are near restricted to the myrtaceous tribe Chamelaucieae.

A STUDY ON MINDARUS KOCH IN CHINA WITH DESCRIPTIONS OF NEW SPECIES AND NEW SUBSPECIES (HOMOPTERA: MIN-DARIDAE)*

Abstract This paper deals with the genus Mindam Koch from China. The phylogeny of the genus is discussed. M. keteleerifoliae is regarded as the most advanced species, M. obliquus and M. piceasuc-tus are more advanced than M. abietinus, M. japonicus and M. victoria. The origin centre of the genus may be in Europe and the differentiation centre of the genus may be in Hengduan Mountains Region of China. Geological distribution of the genus shows island-shaped pattern. Five species from China was described in this paper, including one new species, M. piceasuctus Zhang and Qiao, one new subspecies, M. abietinus triprimesensori Zhang and Qiao and one newly recorded species, M. abietinus abietinus Koch 1856. A key to the Chinese species of Mindarus is given. The specimens of five species from China are deposited in the Institute of Zoology, Academia Sinica.     

The freshwater palaemonid prawns (Crustacea: Decapoda: Caridea) of Myanmar

The taxonomy of the palaemonid freshwater prawns of Myanmar is reviewed and 19 species are recorded. These belong to three genera, with 17 species of Macrobrachium, one species of Palaemonetes and one species of Leptocarpus. The identities of Palaemon spinipes birmanicus Schenkel, 1902, and Palaemon naso Kemp, 1918, are clarified with both recognised as distinct taxa. The taxonomy of several poorly known species of Macrobrachium,viz. M. villosimanus (Tiwari, 1949), M. peguense (Tiwari, 1952), M. hendersoni (De Man, 1906) and M. platyrostrum (Tiwari, 1952) is revised and discussed. Five species are reported from Myanmar for the first time, viz. Macrobrachium lamarrei (H. Milne-Edwards, 1837), M. dayanum (Henderson, 1893), M. lanchesteri (De Man, 1911), M. nipponense (De Haan, 1894), and Palaemonetes sinensis (Sollaud, 1911). One new species, Macrobrachium lanatum, which is closely allied to M. scabriculum (Heller, 1862) and M. dolichodactylus (Hilgendorf, 1879), is described and figured.     

Isolation of Malassezia globosa and M. sympodialis from patients with pityriasis versicolor in Spain

Pityriasis versicolor is a superficial infection of the stratum corneum by several yeast species formerly collectively named Malassezia furfur. The genus Malassezia has been recently enlarged with new species. With the exception of M. pachydermatis, the remaining six species have an absolute requirement in vitro for supplementation of long-chain fatty acids in media. These lipophilic yeasts comprise six species: M. furfur, M. globosa, M. obtusa, M. restricta, M. slooffiae and M. sympodialis. The aim of this study was to establish whether there was any association between the various species of Malassezia and pityriasis versicolor lesions. Thus, we studied the isolates from 79 patients with pityriasis versicolor, both from lesions and from apparently healthy skin close to the visible lesions. In pityriasis versicolor lesions, the species most frequently isolated was M. globosa (90%), followed by M. sympodialis (41%). Almost all isolates (99%) belonged to one of these two species. The most frequent pattern was M. globosa as the sole species (58% of cases), although the association with M. sympodialis was also frequent (30%). These results confirmed M. globosa as the main agent of pityriasis versicolor and M. sympodialis as the second agent in importance. Malassezia globosa was found to be a species with high levels of esterase and lipase enzymes of probable importance in their pathogenicity. This revised version was published online in June 2006 with corrections to the Cover Date.     

Microlicia crassa and M. maculata spp. nov. (Melastomataceae) from Minas Gerais,Brazil: morphology and leaf anatomy

Two new species of Microlicia from campos rupestres of Minas Gerais are described, illustrated and compared with their relatives. Microlicia crassa sp. nov. is similar to M. formosa, and M. maculata sp. nov. is similar to M. isophylla and M. tetrasticha. The trichomes covering both surfaces of the leaves of the two new species and their relative, M. isophylla may be characterized as sessile glands under a stereomicroscope, but anatomical studies revealed the presence of a short stalk. Microlicia crassa and M. maculata are assessed as “Endangered”, according to the IUCN categories and criteria.     

<Emphasis Type="Italic">Mycena haushoferi</Emphasis>, a new species of section <Emphasis Type="Italic">Intermediae</Emphasis> from Germany

Mycena haushoferi, a new species of the section Intermediae collected in Bavaria, is described and compared with four other species of the sect. Intermediae known from the Northern Hemisphere and with M. cystidiosa and M. metuloidifera, two species of sect. Metuloidiferae. The five known species of Northern Hemisphere of section Intermediae are keyed out.     

A revision of West Palaearctic species of the Micropsectra atrofasciata species group (Diptera: Chironomidae)

Phylogenetic relations among selected Micropsectra (Diptera: Chironomidae) species are inferred using mitochondrial COII gene sequences and morphological characters. Both maximum parsimony and Bayesian analyses indicate a monophyletic atrofasciata species group. However, some species morphologically similar to M. atrofasciata (Kieffer) in the adult male, i.e. M. appendica sp. nov. and M. logani (Johannsen), are placed outside the atrofasciata group in the gene trees. The phylogenetic hypotheses based on parsimony analyses of the combined molecular and morphological data sets weakly support a monophyletic atrofasciata group including M. appendica sp. nov. and M. logani if third positions in the COII gene sequences are excluded. In the taxonomic part of this study, adult males, pupae and larvae of Micropsectra aristata Pinder, M. atrofasciata, M. bavarica sp. nov., M. klinki sp. nov., M. logani, M. pallidula (Meigen) and M. schrankelae sp. nov. , and adult males and pupae of M. appendica sp. nov. and M. sofiae sp. nov. as well as adult males of M. andalusiaca Marcuzzi, M. calcifontis sp. nov., M. freyi Storå, M. longicrista sp. nov., M. robusta sp. nov. , and M. zernyi Marcuzzi are described and diagnosed. Micropsectra bidentata (Goetghebuer), M. jokaquarta Sasa & Ogata, M. miki Marcuzzi, M. pallida Goetghebuer, M. subnitens Goetghebuer, M. suecica (Kieffer) and M. shouharasima Sasa are new junior synonyms of M. atrofasciata; Micropsectra groenlandica Andersen and M. utonaitertia Sasa are new junior synonyms of M. logani; Micropsectra candida Chaudhuri & Datta, M. franzi Goetghebuer and M. viridiscutellata Goetghebuer are new junior synonyms of M. pallidula. Comments on the ecology, distribution and systematics of each species are provided. Keys to all known life stages are presented, as well as an annotated list of species morphologically similar to species in the atrofasciata group and nomina dubia in the atrofasciata group. Chironomus mimulus Holmgren is transferred to the genus Micropsectra. © 2006 The Linnean Society of London, Zoological Journal of the Linnean Society, 2006, 146 , 165–225.
