Abstract The structure and stereochemistry of the siderophore isolated from the culture medium of Ralstonia eutropha (formerly Alcaligenes eutrophus) could be elucidated as staphyloferrin B by spectroscopic methods and chemical degradation. The relationship of the three species of the new genus Ralstonia is reflected in the observation that all three form citrate sidero-phores.

AbstractThe crustose lichen genus Mycoblastus in the Northern Hemisphere includes eight recognized species sharing large, simple ascospores produced 1–2 per ascus in strongly pigmented biatorine apothecia. The monophyly of Mycoblastus and the relationship of its various species to Tephromelataceae have never been studied in detail. Data from ITS rDNA and the genes coding for translation elongation factor 1-α and DNA replication licensing factor mini-chromosome maintenance complex 7 support the distinctness of Mycoblastus s. str. from the core of the Tephromelataceae, but recover M. fucatus and an undescribed Asian species as strongly supported within the latter group. We propose accommodating these two species in a new genus, Violella, which is characterized by its brownish inner ascospore walls, Fucatus-violet hymenial pigment granules and secondary chemistry, and discuss the position of Violella relative to Calvitimela and Tephromela. We describe the new species Violella wangii T. Sprib. & Goffinet to accommodate a new species with roccellic acid from Bhutan, China, India and the Russian Far East. We also exclude Mycoblastus indicus Awasthi & Agarwal from the genus Mycoblastus and propose for it the new combination Malmidea indica (Awasthi & Agarwal) Hafellner & T. Sprib.

Sequential Information

Abstract Chromopeptide siderophores (azotobactin 87-1 and -II) were isolated from an iron deficient culture medium of Azotobacter vinelandii ATCC 12837 (=DSM 87). Their structures were elu­ cidated by chemical degradation studies and spectroscopic methods, especially 2D-NMR-tech-niques. Total assignments of 1H-, 13C-, and 15N-resonances based on 2D-HOHAHA-, 1H/13C-HMQC-, 1H /13C-HMBC-, 1H /15N-HMQC/TOCSY-, and 1H/15N-HMBC-experiments are given as well as sequential information derived from 1H/1H-NOESY-, 1H /13C-HMBC-and 1H/ 13N-HMBC-experiments. Both Az 87-1 and Az 87-11 consist of a tetracyclic chromophore -(1S)8,9-dihydroxy-4-oxo-2,3,4,5-tetrahydro-1H,10cH-3a,5,10b-triazaacephenantrylene-1-carb-oxylic acid -and a decapeptide chain linked with the N-terminus to the carboxy group of the chromophore containing also modified, non-proteinogenic amino acids. The sequence L-Ser-D-Ser-L-Hse-Gly-D-threo-OHAsp-Hse-Hse-Hse-D-N5OH-N5-R-Hbu-Om-L-Hse was determined for Az 87-1, while Az 87-11 contains a C-terminal L-Hse-lactone instead. Iron is chelated by the catecholic group of the chromophore, the β-hydroxy aspartic acid, and the hydroxamate function formed by N5-hydroxyornithine and R-β-hydroxybutyric acid.

AbstractBased mainly on an analysis of the host ranges of the species presently placed in Cactodera, sensu lato, and of selected morphological characteristics, an attempt is made to improve the definition of the genus which, after exclusion of C. betulae and C. johanseni, is considered to be monophyletic. The host range of Cactodera, sensu stricto, appears to be restricted to the subclass Caryophyllidae with the ten known species showing an adaptive radiation on host genera in five families of the orders Caryophyllales and Polygonales. This may be a result of co-evolution. Cactodera betulae cannot be assigned to any of the presently recognised genera of cyst-forming nematodes and therefore Betulodera gen. nov. is proposed with B. betulae comb. nov. as the type and only species. The relationship of Betulodera gen. nov. to other genera of Heteroderidae and to some undescribed heteroderid species has still to be evaluated. The new genus is characterised by circumfenestrate cysts with only a slightly protruding vulval cone, three incisures in the lateral field of the second-stage juveniles and presence of phasmids in the males. The hosts are in unrelated plant orders and subclasses. Cactodera aquatica, a species inquirenda, is returned to the genus Heterodera and Heterodera johanseni (Sharma et al. , 2001) comb. nov. is proposed for C. johanseni.

(Philippines, Mindanao) and A. vitellinus sp. nov. (Indonesian New Guinea), is described. This new genus combines characters with a mosaic spread among other cillaeine genera. We present a wide comparison of genera among the subfamily Cillaeinae, making it possible to elaborate a detailed diagnosis of the new genus and trace some order in character patterns and propose a hypothesis on the relationship of this genus to other groups known from the Indo-Malayan and Australian Regions. A detailed diagnosis of the new genus and key to the new species are given. The Adocimus-complex of the related genera including Allenipeplus gen. nov., Adocimus Murray, 1864, Ithyphenes Murray, 1864, Platynema Ritsema, 1885 and probably Brittonema Kirejtshuk, 2011 is defined. Some notes on the taxonomy of the genera Liparopeplus Murray, 1864 and Xanthopeplus Fairmaire, 1880, stat. nov. are given. Additionally, designation of a lectotype for Liparopeplus colastoides Murray, 1864 is made.

Calixomerialasalleigen. n. et sp. n. is described as a new genus and species of Sceliotrachelinae. Calixomeria most closely resembles genera of the Aphanomerus-cluster but possesses several characters that readily separate it from other sceliotracheline genera. The key of Masner and Huggert (1989) is modified to accommodate Calixomeria, and the relationship of the genus to other members of the subfamily is discussed.

By taking Flavalona gen. nov. out of Alona s.l. (Cladocera: Anomopoda: Chydoridae), the last major clade has now been removed from this polyphyletic assemblage. Flavalona gen. nov. is a monophylum defined by having three, rarely two connected head pores and slit-shaped, rarely rounded lateral head pores. Postabdomen rather long, distally narrowed, with robust marginal denticles and weakly developed lateral fascicles of setules. End-claw weakly curved and with short basal spine. Male postabdomen with gonopores opening at the end of a penis-like outgrowth. Trunk limbs: exopodite of P2 with seta; inner portion of P4 with flaming-torch shaped setae; P5 with filter plate of three setae; P6 a large simple lobe. The relationship of the new genus with other Aloninae remains to be determined. A key to the 11 species of the genus is provided and a discussion of their geographic distribution and habitat type is given.

Inti gen. nov. (Hymenoptera: Eulophidae: Entedoninae), is described from Costa Rica and the Dominican Republic, and includes one new species, I. levis sp. nov. The new genus is characterized by four autapomorphies, and the possession of an additional 14 synapomorphies. Inti is compared to the Australian genus Horismenoides Girault with which it shares the most apomorphies, indicating a possible sister-group relationship. The relationship of Inti to the tribe Euderomphalini and to other groups in the subfamily is discussed briefly.

AbstractThe relationship ofAspicilia uxoriswithinMegasporaceaeis assessed within a phylogenetic context. ‘Aspicilia’uxorisand other related species are recovered as sister to the genusLobothallias. str. and described here as a new genus.Teuvoa(Ascomycota,Megasporaceae) is erected based on nuclear ITS and LSU sequence data and morphological characters. In addition toTeuvoa uxoris, a second species,T. junipericola,is added to the new genus based on material collected from North America.Teuvoa junipericola, T. uxorisandT. tibeticaform a group with 8-spored asci, absence of extrolites, rather short-sized conidia and ascospores, lack of a subhypothecial algal layer, and different substratum preferences (on organic substratum) with a sister relationship to genusLobothallias. lat. (AspiciliasubgenusPachyothalliaClauzade & C. Roux). Based on spore measurements of the holotypes,Lecanora ferganensisTomin from central Asia (Kyrgyzstan, Tajikistan and Uzbekistan),Lecanora atrodiscataGintovt, from Tajikistan andLecanora takyroidesDzhur. from Turkmenistan are new synonyms toT. uxoris. A lectotype forLecanora ferganensisis designated, expanding the known distribution ofT. uxorisfrom Algeria, Morocco and Spain, into Central Asia.

The new genus Polythrinciopsis, with the type species P. phragmitis, is described from a leaf spot of Phragmites communis Trin, in eastern New South Wales. The genus is characterized by hypophyllous conidiophores, which develop in clusters from a few fungal cells in the stomatal opening and which show a strongly unilateral placement of spore scars; by large, hyaline to very pale olivaceous, two-celled, acrogenous conidia; and by an abundant superficial mycelium developing on the under side of the leaf spots. The relationship of this fungus to some other genera of the Fungi Imperfecti is discussed.

A new genus, Pentaceration, in the janiroid asellote family Paramunnidae from the Bass Strait area in south-eastern Australia is diagnosed. The distinguishing characters of species in the new genus are 1 central and 2 lateral spines on the frontal margin of the head, elongate eyestalks, lateral spines of varying length on pereonites 2–7, and reduced width of pereonite 4 compared with 3 and 5. Descriptions are presented of the type species, Pentaceration bassiana, and a second new species, P. spinosissima. The new genus appears to be wide-spread around Australia and New Zealand, where several as yet undescribed species have been noted, ranging from the upper sublitoral to abyssal depth. The relationship of Pentaceration to other paramunnid genera with covered coxae on all legs is discussed.
