New anamorphic yeast species: Candida infanticola sp. nov., Candida polysorbophila sp. nov., Candida transvaalensis sp. nov. and Trigonopsis californica sp. nov

Three new species of Candida and a new species of Trigonopsis are described based on their recognition from phylogenetic analysis of gene sequences from large subunit ribosomal RNA, ITS1/ITS2 rRNA, mitochondrial small subunit rRNA and cytochrome oxidase II. Candida infanticola sp. nov. (type strain NRRL Y-17858, CBS 7922) was isolated from the ear of an infant in Germany and is closely related to Candida sorbophila. Candida polysorbophila sp. nov. (type strain NRRL Y-27161, CBS 7317) is a member of the Zygoascus clade and was isolated in South Africa as a contaminant from an emulsion of white oil and polysorbate. Candida transvaalensis sp. nov. (type strain NRRL Y-27140, CBS 6663) was obtained from forest litter, the Transvaal, South Africa, and forms an isolated clade with Candida santjacobensis. Trigonopsis californica sp. nov. (type strain NRRL Y-27307, CBS 10351) represents a contaminant from wine in California, and forms a well-supported clade with Trigonopsis cantarellii, Trigonopsis variabilis and Trigonopsis vinaria.

Their cultural features are also presented.     

Description ofGerres chrysops sp. nov. From Thailand and redescription ofGerres setifer (Hamilton, 1822) andG. Decacanthus (Bleeker, 1865) (perciformes: Gerreidae)

Gerres chrysops, a new gerreid species from the Gulf of Thailand, is described on the basis of 29 specimens, 58–83 mm in standard length (SL). A small-sized species (less than 100 mm SL), it is characterized by a silvery-gold sheen on the head and trunk, vivid yellow or yellowish-hyaline fins in life, two supraneural bones (formula 0/0/2/) and dorsal fin rays usually IX, 10. The new species is similar toG. decacanthus (Bleeker, 1865) andG. setifer (Hamilton, 1822), which are redescribed. being similarly small valid gerreid species characterized by two supraneural bones. Together, the three species comprise “theGerres setifer complex.”Gerres chrysops differs from bothG. decacanthus andG. setifer in life and fresh colors, the body being silvery-gold with vivid yellow or yellowish dorsal, caudal, anal and pelvic fins, and yellowish-hyaline pectoral fins (vs. silver body with hyaline fins in the latter two species).Gerres setifer differs fromG. chrysops andG. decacanthus in having the last dorsal fin spine longer than the penultimate spine (vs. almost same length or shorter), usually ten dorsal fin spines and nine soft dorsal rays (vs. usually IX, 10), and 8 or 9 lower series gill rakers (vs. usually 7).Gerres decacanthus differs fromG. chrysops andG. setifer in having a shorter head, lesser body depth at the first anal fin spine base, lesser body width at the pectoral fin base, and shorter second dorsal and third anal fin spines. The new species is currently known only from Angsilla, near Bangsaen, and around Si Chang Island, northeastern Gulf of Thailand.Gerres decacanthus inhabits southern Chinese waters andG. setifer is currently known from the Bay of Bengal to the Andaman Sea.     

Aciculosporium sasicola sp. nov. on witches' broom ofSasa senanensis

A new species ofAciculosporium, A. sasicola (anam.Albomyces sasicola), is described and illustrated. The fungus differs fromAciculosporium take by its small asci and ascospores, though witches' broom and signs probably caused by the former onSasa senanensis are similar to those caused by the latter on bamboos.

A. robusta sp. nov., a new species of Achlya (Saprolegniales, Straminipila) from a polluted Argentine channel

Achlya robusta sp. nov. was found on litter (floating twigs, leaves, and roots) in an artificial polluted channel, near a petroleum refinery, in Buenos Aires province, Argentina. The species is described, illustrated and compared with other species of the genus. A. robusta produces mainly smooth and papillate, tuberculate or bullate oogonia and monoclinous antheridial branches. It develops spherical and subglobose oogonia, with the oogonial wall yellowish and containing mainly immature oospheres. The oospores are eccentric and ranging from (1) 4–17 (30) per oogonium.     

Spirobolbolaimus bathyalis,gen. nov., sp. nov. (Nematoda,Microlaimidae) from the Mediterranean (Calvi)

Spirobolbolaimus bathyalis gen. nov., sp. nov. is described from the continental slope off Calvi (Mediterranean). The new genus Spirobolbolaimus belongs to the Microlaimidae Micoletzky, 1922 and is closely related to the genus Bolbolaimus Cobb, 1920. It can be differentiated from Bolbolaimus by its multispiral amphideal fovea and by its six rows of postamphideal setae.     

Liopropoma dorsoluteum sp. nov., a new serranid fish from Okinawa, Japan

A new serranid fish,Liopropoma dorsoluteum sp. nov., is described on the basis of two specimens from Yaeyama Is., Okinawa, Japan. The new species is most similar toL. erythaeum Randall & Taylor, 1988, in having the following characters: Dorsal fin rays VIII, 12; anal fin rays III, 9; pored lateral line scales 52–53; anterior nostril situated midway between posterior nostril and anterior tip of snout; slightly forked caudal fin with both lobes rounded. It differs from the latter species in having a shorter pectoral fin (23.4–23.8% SL vs. 26.9–29.0% SL), greater preanus length (65.6–68.0% SL vs. 63.3–65.1% SL), fewer gill rakers (6+12 vs. 6–7+14–15) and yellow coloration on the back (vs. light red on head and body) in fresh specimens.     

Notes on the life histories of Boergesenia and Valonia (Siphonocladales,Chlorophyta)

Life history studies were carried out with isolates of Boergesenia forbesii (from Western Australia), Valonia fastigiata (Hawaii) and V. utricularis (Canary Islands, Mediterranean Sea) cultivated under laboratory conditions. Ploidy levels of nuclei were identified by micro spectrophotometric DNA content measurements after Feulgen staining. Fundamentally, the life history in both genera is diplohaplontic. Autodiploidization phenomena have been observed favoring the diploid generation. In contrast to other genera of the Siphonocladales s. str. producing biflagellate diploid zoospores (e.g. Ernodesmis, Boodlea), Valonia develops haploid and diploid zoospores with four flagella. No diploid zoospores were observed in Boergesenia.     

Three new species of anamorphic yeasts phenotypically and phylogenetically related toCandida mesenterica: The description ofCandida fungicola sp. nov.,Candida sagamina sp. nov., andCandida fukazawae sp. nov. isolated from fruit bodies of mushrooms

Four strains of anamorphic yeasts isolated from fruit bodies of mushrooms collected in Japan were found to represent three new species of the genusCandida. These species resembleCandida mesenterica in characteristics commonly employed in the classification of yeasts. On the basis of DNA-DNA reassociation, however, they were clearly distinguished fromC. mesenterica and from one another. Three new species,Candida fungicola, Candida sagamina, andCandida fukazawae, are proposed for these yeasts. The analysis of SSU rDNA sequences suggested that these three species were closely related to each other and toC. mesenterica andC. suecica.     

Lanceispora phyllophila sp. nov. on petioles of unknown dicotyledonous leaves in Singapore

Lanceispora phyllophila is described based on specimens of petioles from an unidentified dicotyledonous host collected at Bukid Timan, Singapore. It is illustrated with interference contrast micrographs and compared with the type speciesL. amphibia. Lanceispora phyllophila differs fromL. amphibia in having smaller ascomata and longer ascospores.     

Pseudomicrodochium fusarioides sp. nov., isolated from human bronchial fluid

A fungus from bronchial lavage fluid from a patient with pulmonary infiltration was isolated in pure culture and identified as a species of Pseudomicrodochium. It is compared and contrasted with other species of the genus, in particular P. suttonii, and formally described as P. fusarioides.     

Phlebotomus (Legeromyia) multihamatus subg. nov., sp. nov. from Gabon (Diptera: Psychodidae)

During a research project aimed at the study of the Culicinae fauna of Gabon and carried out in the National Park of La Lopé, we captured an unknown sandfly male specimen (genus Phlebotomus) by CDC miniature light trap belonging to a new species for Science. Furthermore, the originality of his genitalia does not allow us to include this species in one of the existing subgenus, thus in this paper we propose the creation of a new subgenus, as Phlebotomus (Legeromyia) multihamatus sp. nov., subg. nov. described from the National Park of La Lopé, through one male captured with CDC miniature light trap. A new species and a new subgenus of sandfly is characterised by a short style with three spines, a paramere wearing a basal hook as well as a basal pouch and the absence of basal lobe on the coxite. The originality of the genitalia of the male gives way to discussion about potential primary homologies between P. multihamatus sp. nov. and Phlebotomus (Abonnencius) fortunatarum, Phlebotomus (Anaphlebotomus) stantoni and Phlebotomus (Euphlebotomus) argentipes, which should be verified for future studies. The discovery of this new species in Gabon must encourage the study of sandflies in this country.     

Sorex rohweri sp. nov. (Mammalia, Soricidae) from northwestern North America

Sorex rohweri sp. nov. is described on the basis of a series of specimens from the Olympic Peninsula and adjacent western regions of Washington State, USA, and southwestern British Columbia, Canada. It has been misidentified as Sorex cinereus Kerr, 1792, which occurs in the Cascade Range in west-central Washington, in coastal British Columbia, and regions farther to the northeast. The new species is distinguished from S. cinereus by numerous morphological characters: differences in craniodental dimensions; different location and form of the medial tines of the upper incisors; presence of patent postmandibular foramina; different intensity and distribution of dental pigmentation; and different form of the glans penis, along with other details. The combination of characters also separates it from sympatric species of Sorex. Phylogenetic inference of cytochrome b sequences from two specimens of the proposed new species shows them to be distinct from Sorex cinereus and from five sympatric Sorex species, supporting their designation as members of a new species.
