The schizomid fauna of the Seychelles is reviewed and the following taxa are recognised: Apozomus gerlachi, sp. nov., Bamazomus aviculus, sp. nov., Mahezomus apicoporus, sp. nov., Anepsiozomus sobrinus, sp. nov., Ovozomus similis (Hirst), Secozomus latipes (Hansen) and Zomus bagnallii (Jackson). Four new genera are recognised, each represented by a single species: Mahezomus, gen. nov. (type species M. apicoporus, sp. nov.); Anepsiozomus, gen. nov. (type species A. sobrinus, sp. nov.); Ovozomus, gen. nov. (type species Schizomus similis Hirst); and Secozomus, gen. nov. (type species Schizomus latipes Hansen). Three species of Schizomus described from Madagascar are transferred to Bamazomus: B. madagassus (Lawrence), comb. nov., B. milloti (Lawrence), comb. nov. and B. vadoni (Lawrence), comb. nov. Problems in the systematics of the subfamily Hubbardiinae are explored, especially with regard to the high number of genera currently recognised. Biogeographic patterns of the arachnid fauna of the Seychelles are briefly explored, and a list of the Scorpiones, Pseudoscorpiones, Amblypygi, Schizomida and Palpigradi is included.

AbstractThe new generic names Metamelanea Henssen and Strotnatella Henssen are described inthe Lichinaceae. They are denned by the developmental morphology of the ascocarp and thallus structure. In both genera the thallus is subfruticose, and the cyanobiont a single-celled member of the Chroococcales. The genus Metamelanea is based on the type species M.umbonata Henssen, newly described from the Alps, and M. melambola (Tuck.) Henssen comb, nov., found in North America. The genus Strotnatella is based on the single species, S. bermudana (Riddle) Henssen, formerly Psorotichia bermudana Riddle. The new genera are compared with species of other genera of the Lichinaceae: Gyrocollema, Lecidopyrenopsis and Porocyphus; some micrographs of Lecidopyrenopsis corticola Vainio. are also included. The new combination Porocyphus ocellatus(Th. Fr.) Henssen is made; Pyrenopsis triptococcus Nyl. is selected as lectotype of Pyrenopsis subgen. Cladopsis Nyl. (syn. Cladopsis (Nyl) Hue).

Two new form-genera of the Fungi Imperfecti, Sphaeropsidales are described. Idiocercus n. gen. is characterized by punctiform, unilocular, pycnidia, annellophores and hyaline, aseptate conidia with an elongated basal frill, and contains two species: I. pirozynskii n. sp. (type species) and I. macarangae (T. S. Ramakrishnan) n. comb. Bellulicauda n. gen. is based on a single species, B. dialii (Syd.) n. comb., and features lacunose stromata, annellophores, and pale brown, aseptate conidia with an elongated basal frill. Idiocercus and Bellulicauda are compared and contrasted with Diachorella, Plagiorhabdus, and Strasseria, genera which are shown to produce appendaged phialospores. Plagiorhabdus is tentatively reduced to synonymy with Strasseria.

A new family of early derivative Parasitengona (Acari: Prostigmata), Allotanaupodidae fam. nov., is described from New Zealand based on adults and deutonymphs of two new genera and five new species and a new superfamily Allotanaupodoidea is erected to accommodate it. The new family is characterized by the absence of prodorsal trichobothria and sensory areas, the presence of one or two pairs of plates with multiple setae on C to PS rows of dorsal hysterosoma, the presence of only two pairs of genital acetabula in adults, and short, distally inserted palptarsus on the palptibia. The family consists of two subfamilies (Allotanaupodinae subfam. nov. and Paratanaupodinae subfam. nov.), with the former endemic to New Zealand. Allotanaupodinae subfam. nov. has a single genus, Allotanaupodus gen. nov., which is represented by three new species from New Zealand: Allotanaupodus williamsi sp. nov. (type species) from Kawau I., Auckland, Allotanaupodus orete sp. nov. from Orete Forest, Te Puia Hut and Allotanaupodus winksi sp. nov. from Mt. Messenger, Taranaki. The eyeless Paratanaupodinae subfam. nov. consists of two genera: Nanotanaupodus gen. nov. and Paratanaupodus Andre & Lelievre-Farjon, 1960. The type genus Paratanaupodus Andre & Lelievre-Farjon, 1960 was previously placed in the Tanaupodidae and is represented by a single species, Paratanaupodus insensus André & Lelievre-Farjon, 1960, from South America. Nanotanaupodus gen. nov. is represented by two new species from New Zealand: Nanotanaupodus andrei sp. nov. (type species) from Waituhi Saddle and Nanotanaupodus gracehallae sp. nov. from Orete Forest, Te Puia Hut. A key to superfamilies of terrestrial Parasitengona (post-larval stages) is provided, along with keys to subfamilies, genera and species of the new family.

Four new genera including five new species are described. All are from north-eastern Queensland. Barbaragraecia comprises two new species. B. unicorn Rentz & Su, gen. et sp. nov. (the type species) and B. richardsoni Rentz & Su, sp. nov. Geoffagraecia is known from a single species, G. gwinganna Rentz & Su, sp. nov. the type species. Greenagraecia Rentz & Su, gen. et sp. nov. is known from two species, G. attenuata Rentz & Su, gen. et sp. nov., the type species and G. cooloola Rentz & Su, gen. et sp. nov.. The unrelated genus Nicsara Walker 1869 is discussed and species with falcate ovipositors are removed and placed in a new genus, Larifugagraecia Rentz & Su gen. nov., with Nicsara spuria Redtenbacher 1891 designated as the type species. Two species are removed from Nicsara and placed in Larifugagraecia. These are N. cornuta (Redtenbacher 1891) and N. spuria. Other species remain in Nicsara until they can be further assessed. Biological and ecological notes accompany detailed descriptions of the new species along with many morphological illustrations. Illustrations also are provided for L. spuria gen. nov. A key to the described fully-winged Australian agraeciine genera is provided at the end of the paper.

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

The development of molecular tools and in particular the use of 16S rRNA gene sequencing has had a profound effect on the taxonomy of many bacterial groups. Gram-positive organisms that encompass the genera Lactobacillus and Clostridium within the Firmicutes are examples of taxa that have undergone major revisions based on phylogenetic information. A consequence of these reorganizations is that a number of organisms are now recognized as being misclassified. Previous studies have demonstrated that Lactobacillus catenaformis and Lactobacillus vitulinus are phylogenetically unrelated to Lactobacillus sensu stricto, being placed within the Clostridia rRNA cluster XVII. Based on the phenotypic, chemotaxonomic and phylogenetic data presented, it is proposed that L. catenaformis and L. vitulinus be reclassified in two new genera, named respectively Eggerthia gen. nov., with the type species Eggerthia catenaformis gen. nov., comb. nov. (type strain DSM 20559T = ATCC 25536T = CCUG 48174T = CIP 104817T = JCM 1121T) and Kandleria gen. nov., with the type species Kandleria vitulina gen. nov., comb. nov. (type strain LMG 18931T = ATCC 27783T = CCUG 32236T = DSM 20405T = JCM 1143T).

ABSTRACTThe systematics of parts of the Odontopleuridae are revised using character analyses tracing homologous structures, and a computerised cladistic analysis. The choice of outgroup is shown to affect the result of the analysis. Several synapomorphies place Selenopeltis, the type genus of the Selenopeltinae Hawle & Corda, 1847 as sister genus to Dicranurus. The latter's close relationship to Miraspis, type genus of the Miraspidinae Richter & Richter, 1917 is confirmed. The Selenopeltinae therefore becomes a senior subjective synonym of the Miraspidinae. The Selenopeltinae includes about 90 of the over 380 named odontopleurid species known to date (excluding accepted synonyms). The Ceratocephalinae is recognised, including about 30 species. The paired, large pygidial border spines present in most odontopleurids are in some species not homologous, and a falsifiable hypothesis is proposed for the homology of the ‘true major border spines’. This structure is the posterior pleural spine of the tenth postcephalic segment in selenopeltines, ceratocephalines and odontopleurines, and in acidaspidines and apianurines it is the serially homologous spine of the eleventh postcephalic segment. The spine belongs to the first pygidial segment in all taxa except ceratocephalines, where it is on the last thoracic segment. The homology in selenopeltines of the progressive restructuring of the cheek border is reviewed, explaining the supramarginal appearance of the genal spine. The presence and homology of the sublobation of L1 in odontopleurids is discussed, and it may be homologous with the sublobation in lichids. The strongly differentiated thoracic segmental lengths (exsag.), with maximum length reached in the anterior part of thorax, and the much reduced length of the posterior segments, are aspects of a single character-complex, uniquely derived within the Selenopeltinae. The ontogenetic origin of the anterior and posterior pleural spines is reviewed. The presence in Ceratocephala of two instars in one meraspid degree is discussed. A cladistic analysis of selenopeltine and ceratocephaline genera does not entirely resolve the topology of the phylogenetic tree of these taxa, but it confirms Selenopeltis as sister taxon to Dicranurus. These two genera belong in a clade also including Miraspis, Selenopeltoides, and Ceratonurus. Two new genera are erected, Ceratocara and Archaeopleura, the latter with type species A. kazakhensis sp. nov.

The authors provide a new circumscription for genera of the “Cryptanthoid complex” of Bromeliaceae subfam. Bromelioideae, originally composed of Cryptanthus, Lapanthus, Orthophytum, and Sincoraea, on the basis of new or re-evaluated ecological, geographical and morphological evidence, as well as molecular phylogenies. A new generic status is proposed for Cryptanthus subg. Hoplocryptanthus and two new genera, Forzzaea, and Rokautskyia, as well as four new subgenera in Orthophytum (Capixabanthus, Clavanthus, Krenakanthus, and Orthocryptanthus) are described to render taxonomic units monophyletic. The recognized taxa are well circumscribed by the combination of geographical range, ecology and morphological characters (sex distribution, leaf succulence, sepal and petal size and connation, petal appendages, pollen and stigma morphology, fruit size, calyx persistency, seed size and number per fruit). Field collected living specimens of 78 of the 81 species of Cryptanthus s.l., all species of Lapanthus, 58 of the 59 species of Orthophytum, and all species of Sincoraea were analysed in habitat and/or in cultivation, allowing the documentation and illustration of new and underutilized characters. The molecular analysis incorporated 91 accessions representing 33 species of Cryptanthus, all species (3) of Lapanthus, 42 species of Orthophytum, and 9 species of Sincoraea, including the type species for the first three genera and four outgroup taxa. The results suggest, that some morphological characters generally considered homoplasious for Bromelioideae, for the “Cryptanthoid complex”, are not homoplasious at least within the obtained, biogeographycally well delimited clades and their taxonomical utility is redeemed.
