Fredericella Sultana

Of the 10 species of freshwater bryozoans previously reported from Australia, only Fredericella australiensis, Hyalinella lendenfeldi and Lophopodella carteri can be positively confirmed from existing preserved material. From a survey of all known museum collections of freshwater bryozoans comes compelling evidence that a specimen labelled ‘Plumatella toanensis’ is actually Hyalinella lendenfeldi, including the only known statoblasts of this species. Plumatella agilis is recognised tentatively pending new material. Fredericella sultana, Plumatella emarginata and P. repens are not represented by any known specimens, although they are likely to occur in Australia. Hyalinella punctata and Gelatinella toanensis have been previously reported in error. Two other previously misidentified specimens, including Hyalinella vaihiriae, are now reported as new species: Plumatella velata and P. rieki. A taxonomic key is given for Australian freshwater bryozoan species, including species both verified from Australia and others only presumed to occur there.

AbstractTwo new species of Camallanus are described from Australian freshwater turtles. Camallanus beveridgei sp. nov. is reported from Elseya dentata in Northern Territory. It differs from other species of the genus parasitic in turtles by several characters including the shape of the median ridge in the buccal capsule and the position of the anterior pair of caudal papillae in males. Camallanus sprenti sp. nov. is reported from Elseya latisternum (type host) and Emydura krefftii in northern Queensland. It is closely related to Camallanus tuckeri, and differs from the latter species in possessing a shorter oesophagus. We summarize data on morphology, distribution and specificity of 5 known Camallanus spp. from Australian turtles and provide a key for their identification. Sequence comparison of more than 500 base pairs at the 5′ end of the nuclear 28S rDNA gene confirms the status of C. sprenti and C. beveridgei as new species. Camallanus sprenti differs from the other 4 species of Camallanus from Australian turtles by 16–59 bases (3.1–11.5%) while C. beveridgei differed from the other 4 species by 23–60 bases (4.5–11.6%). Phylogenetic analysis demonstrates close interrelationships among C. tuckeri, C. sprenti and C. beveridgei, the three species with most similar buccal capsules.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Abstract Bed-by-bed sampling of twelve Barremian sections in southeastern France from pelagic basin (Vocontian Basin) to neritic platforms (Arc of Castellane, Arc of Nice and Provencal Domain) has enabled the collection of isochronous samples of the ammonite genus Gassendiceras. Three poorly known species of the Toxancyloceras vandenheckei Zone (Upper Barremian) are revised: G. alpinum, G. multicostatum and G. hoheneggeri; two new species are described (G. rebouleti nov. sp. and G. bosellii nov. sp.). The intraspecific variability of particular species was recognised. This variability is between slender peramorphic and robust paedomorphic extreme morphologies, with the presence of all intermediates.

Two New Species

This paper continues the publication of new data obtained during field studies in remote and poorly studied regions of Laos in 2015–2018. It provides descriptions of two new species (Bulbophyllum brachyscapum Aver. and Sunipia saccata Aver.), emended descriptions of two previously published but insufficiently known species (Cleisostoma verrucosum Aver., Oberonia vesiculifera Aver.) and reports of eight species newly recorded in the flora of Laos (Biermannia calcarata Aver., Bulbophyllum farreri (W. W. Sm.) Seidenf., Didymoplexiella trichechus (J. J. Sm.) Garay, Eria eriopsidobulbon C. S. P. Parish et Rchb. fil., Habenaria ciliolaris Kraenzl., Liparis caudata Aver. et K. S. Nguyen, Odontochilus umbrosus (Aver.) Ormerod, and Porpax ustulata (C. S. P. Parish et Rchb. fil.) Rolfe). Appropriate citations of regional literature, colour illustrations, data on types and distribution, descriptions, etymology, as well as notes on taxonomy and related species are provided for the studied species.
