Bothriospermum longistylum sp. nov. (Boraginaceae) from north China

Based on field investigations as well as morphological and molecular systematic studies we found a new species of Bothriospermum which can be easily distinguished from all other known congeneric species by its unlobed faucal appendages and very long styles. We conducted molecular phylogenetic analyses based on a combined dataset from nrITS, plastid rps16, trnL‐trnF and trnG‐trnS regions. The results indicated that the new species indeed belongs in Bothriospermum and that it is well separated from other congeneric clusters, but that the genus Bothriospermum is paraphyletic with Nihon and Thyrocarpus clusetered within it. As a result, Bothriospermum longistylum sp. nov. is described and illustrated here. A revised key to species of Bothriospermum and a distributional map are also presented.     

Blastodinium galatheanum sp. nov. (Dinophyceae) a parasite of the planktonic copepod Acartia negligens (Crustacea,Calanoida) in the central Atlantic Ocean

A new dinoflagellate species, Blastodinium galatheanum sp. nov., was found parasitizing the planktonic copepods Acartia negligens and Acartia sp. in the Atlantic Ocean between the Azores and the Cape Verde Islands. These copepods have not previously been reported hosting a Blastodinium species. Characters that distinguish the new species are the shape and size of the trophic stage, its host species, and its predominantly solitary existence. Dinospores of Blastodinium galatheanum sp. nov. are peridinioid in nature and morphologically indistinguishable from dinospores of two other previously investigated Blastodinium species. SSU rRNA gene sequences from two isolates of this new species were almost identical and showed similarities to SSU rRNA sequences of other species of Blastodinium. A phylogenetic analysis based on SSU rRNA gene sequences suggested monophyly for all existing sequences of Blastodinium spp., including a sequence from the type species B. pruvoti, presented here for the first time.     

Aphyllon castilloi sp. nov. (Orobanchaceae) from Veracruz,Mexico

Aphyllon castilloi Franc.‐Gut., Cházaro & Espejo (Orobanchaceae), a new species discovered in central Veracruz, Mexico is herein described, illustrated and compared with other Aphyllon species recorded from Mexico. The new species inhabits tropical semideciduous forest, a novel ecosystem for Aphyllon species native to North America, in contrast to most collections from Mexico, which are from warm sandy deserts. In addition, it parasitizes Simsia foetida (Asteraceae: Heliantheae). As far as known, the distribution of the new species is very restricted.     

Crataegus coriifolia sp. nov. (Rosaceae) from Iran

Crataegus coriifolia Sharifnia & Zarrinkolah is described as a new species from Iran. Its taxonomic relationships, ecology and distribution are discussed. An identification key to C. coriifolia and other two‐styled species of Crataegus occurring in Iran is provided.     

Polystomatidae (Monogenea) of Southern African Anura: Eupolystoma vanasi n. sp. parasitic in Schismaderma carens (Smith)

Eupolystoma vanasi is described as a new species of the Polystomatidae parasitic in the urinary bladder of Schismaderma carens in Northern Province and KwaZulu-Natal Province, South Africa. This is the third Eupolystoma species described from Africa and the first polystomatid from Schismaderma, an anuran genus that is primitive with respect to the other African bufonids in which Eupolystoma has been recorded. The species is distinguished by body size (this is the largest Eupolystoma known; mean length of adults 6 mm), by genital spine number (4 in comparison with 6-9 in other species), marginal hooklet length (greater than in other African species), and by the small size of the ovary and testis. In a sample of 27 toads, 37% were infected with up to 130 parasites per host (mean intensity 37). Worm burdens of this magnitude are exceptional amongst polystomatids in general but are characteristic of Eupolystoma, where there may be repeated re-infection of adult hosts and, uniquely, a direct, internal cycle of auto-infection.     

Cousinia brevicaulis sp. nov. (sect. Lasiandra) for the flora of Iran

Cousinia brevicaulis is described and illustrated as a new species from eastern Iran. This species belongs to the C. sect. Lasiandra Bunge as defined by hairy anther tube, yellow, pale yellow or rarely milky flowers, monocarpic growth form and corymbose branching of stem. It is easily distinguished from other species of the section by its very short‐stemmed habit. The new species is distributed in the same region as other species of C. sect. Lasiandra.     

Lobatiriccardia yunnanensis,sp. nov. (Metzgeriales,Aneuraceae) from Yunnan,China

Abstract

The genus Lobatiriccardia Furuki is reported as new to China, from the Dulong River valley, Gaoligong Shan range, Yunnan Province and this material is described as a new species endemic to China, Lobatiriccardia yunnanensis Furuki & D.G. Long, the fifth known species in the genus. The differences between the new species and the other members of the genus are enumerated, along with a key to all known species of Lobatiriccardia.     

Jurinea tortumensis sp. nov. (Asteraceae) from northeast Anatolia,Turkey

A new species, Jurinea tortumensis A. Duran & B. Dogan (Asteraceae), is described and illustrated from Anatolia, Turkey. The species grows on serpentine stony places in the Tortum district (Erzurum Province) in northeast Anatolia. It is morphologically similar to J. consanguinea DC. The pollen characteristics and achene surface morphology of J. tortumensis and J. consanguinea are examined by SEM. Diagnostic morphological characters from closely similar taxa are discussed and arranged in a key. Ecology, conservation status and biogeography of the species are also presented. In addition, the geographical distributions of the new species and other related species are mapped.     

Siphoderina hustoni n. sp. (Platyhelminthes: Trematoda: Cryptogonimidae) from the Maori snapper Lutjanus rivulatus (Cuvier) on the Great Barrier Reef

A new cryptogonimid trematode, Siphoderina hustoni n. sp., is reported, collected off Lizard Island, Queensland, Australia, from the Maori snapper Lutjanus rivulatus (Cuvier). The new species is moderately distinctive within the genus. It is larger and more elongate than most other species of Siphoderina Manter, 1934, has the shortest forebody of any, a relatively large ventral sucker, a long post-testicular zone, and is perhaps most recognisable for the substantial space in the midbody between the ventral sucker and ovary devoid of uterine coils and vitelline follicles, the former being restricted to largely posterior to the ovary and the latter distributed from the level of the anterior testis to the level of the ovary. In phylogenetic analyses of 28S ribosomal DNA, the new species resolved with the other nine species of Siphoderina for which sequence data are available, all of which are from Queensland waters and from lutjanid and haemulid fishes. Molecular barcode data were also generated, for the ITS2 ribosomal DNA and cox1 mitochondrial DNA markers. The new species is the first cryptogonimid known from L. rivulatus and the first metazoan parasite reported from that fish in Australian waters.

     

Cochliopodium arabianum n. sp. (Amorphea,Amoebozoa)

A new species of Cochliopodium isolated from freshwater at Arabia Lake in Lithonia, GA, USA is described based on light microscopic morphology, fine structure, and molecular genetic evidence. Cochliopodium arabianum n. sp., previously labeled as “isolate Con1” in prior publications, has been shown to group within the genus Cochliopodium in our molecular phylogenetic analysis. Light microscopy and fine structure evidence indicates the new isolate not only shares characters of the genus but also unique distinctive features. Cochliopodium arabianum n. sp. is typically round when stationary; or oval to sometimes broadly flabellate or triangular in shape during locomotion, with average length of 35 μm and breadth of 51 μm. Fine structure evidence indicates C. arabianum n. sp. has tower‐like scales, lacking a terminal spine, sharing high similarity with its closest relative C. actinophorum. However, the scales of C. arabianum n. sp. are unique in height and the breadth of the base plate. Both morphological and molecular data, including SSU‐rDNA and COI, indicate that this new species falls in a clade sufficiently different from other species to suggest that it is a valid new species.     

Descriptions of Wardula bartolii n. sp. (Digenea: Mesometridae) and three newly recorded accidental parasites of Boops boops L. (Sparidae) in the NE Atlantic

Four species of digeneans parasitic in the bogue Boops boops from the Spanish coast of the NE Atlantic are described. All are new records for this host, but one species is new and the other three are considered to be accidental parasites. Wardula bartolii n. sp. (Mesometridae) is distinguished from its two congeners on the basis of a range of morphometrical features, such as the post-ovarian extent of the uterus, the relative length of the attachment organ, the position of the pharynx and vitelline fields, and the absence of anterior caecal diverticula. The other three species are Lecithaster confusus Odhner, 1905, Aponurus laguncula Looss, 1907 (Lecithasteridae) and Accacladium serpentulum Odhner, 1928) (Accacoeliidae).     

Syzygium humbertii and S. mortonianum spp. nov. (Myrtaceae) from Madagascar

Two new species, Syzygium humbertii Byng and S. mortonianum Byng, are described from Madagascar. When compared with other Madagascan Syzygium, S. humbertii Byng is characterised by sessile to subsessile leaves, orbicular to oval blades with usually cordate bases and rounded apices, and an obconic hypanthium. Syzygium mortonianum Byng is characterised by relatively long leaves that are typically wrinkled when dried, widely spaced venation, long petioles, and particularly dense capitate inflorescences with many flowers. Both new species are threatened with extinction and known from few contemporary collections.     

ULTRASTRUCTURE OF PRYMNESIUM NEMAMETHECUM SP. NOV. (PRYMNESIOPHYCEAE)1

Based on material collected from Cape Town, a new sand-dwelling, marine species of Prymnesium is described. Using light and electron microscopy, Prymnesium nemamethecum sp. nov. has been found to resemble other species of the genus in size, organelle arrangement, and swimming behavior. It differs from other described species in that it has three types of scales, one of which is confined to the region of appendage insertion and forms a sheath of simple plate scales over the haptonema. In addition, the scales constituting the proximal body scale layer(s) are unusual because they are not simple plate scales but are specifically ornamented.     

Enteromius pinnimaculatus sp. nov. (Cypriniformes: Cyprinidae) from southern Gabon

We present and describe a new species of Enteromius, adding to the 16 species of Enteromius currently recorded from Gabon, West Africa. This new species is distinguished from all other Gabonese Enteromius by the presence of several distinct spots on the dorsal fin in combination with three or four round spots on the flanks. In Africa, it is superficially similar to Enteromius walkeri and with which it shares an unusual allometry in that the proportional length of the barbels decreases as the fish grows. Nevertheless, one can distinguish these species by vertebral number, maximum standard length, the length of the anterior barbels, the length of the caudal peduncle and in most specimens, the number of lateral-line and circumpeduncular scales. These two species also inhabit widely separated drainages, with E. walkeri occurring in coastal drainages of Ghana including the Pra and Ankobra Rivers and the new species occurring in tributaries of the Louetsi and Bibaka Rivers of Gabon, which are part of the Ogowe and Nyanga drainages, respectively. Despite extensive collections in those drainages the new species is known from only two localities, suggesting the importance of conservation of its known habitat.     

Halosarpheia japonica sp. nov. (Halosphaeriales, Ascomycota) from marine habitats in Japan

A new Halosarpheia species, collected from driftwood from Hakkeijima beach, Yokohama, Japan, is described and illustrated and is compared with other species of the genus. The new fungus was growing together with its anamorph on a piece of decaying wood. SSU and LSU rDNA sequences for both morphs were 99% similar. Phylogenetic analyses of SSU and LSU rDNA sequences of the both morphs confirm their anamorph–teleomorph relationship and placed the new fungus in the Halosarpheia sensu stricto clade with high statistical support. Halosarpheia japonica is characterized by its polar appendage that is initially enclosed in a cellular sheath and dissolves in water, the appendage then swells to form a huge tree-like structure. The other three species currently included in Halosarpheia sensu stricto differ from H. japonica by having two polar appendages that uncoil in water to form long filaments.     

Chamaesium jiulongense sp. nov. (Apiaceae) from Sichuan,China

Chamaesium jiulongense X. L. Guo & X. J. He, a new species of Apiaceae from Mt Haite in Jiulong County, Sichuan Province, China, is described. The new species differs from other Chamaesium species by its ultimate segments of the leaves which are 1–3‐lobed, rarely entire, with a narrow, minutely incised, pale brown margin, as well as by the presence of leaf‐like bracts, bracteoles longer than flowers, pubescent styles and oblong fruit with obsolete calyx. Morphological and micromorphological characters of the new species are provided and illustrated.     

Hoya somadeeae sp. nov. (Apocynaceae,Asclepiadoideae) Thailand and lectotypification of Hoya wrayi

A new species from evergreen montane forests of Thailand, Hoya somadeeae Rodda & Simonsson is here described and illustrated. The new species may be superficially confused with the Peninsular Malaysia endemic H. wrayi King & Gamble, but is clearly separated from it by the very elongated peduncles, up to 20 cm long, the revolute corollas, and outer processes of corona lobes with a membranaceous basal appendage. Morphological affinities between the new species and other Hoya species from Thailand and neighbouring Myanmar and Peninsular Malaysia are discussed.     

Amphicreadium n. g. (Digenea: Lepocreadiidae) from monacanthid fishes (Tetraodontiformes) from the coast of northern Tasmania

A new lepocreadiid genus, Amphicreadium, is erected for the species A. denspeniculus n. sp. from Acanthaluteres vittiger and for an unnamed species from Meuschenia freycineti, both from off northern Tasmania. The new genus is distinguished from all other members of its family by its amphistomatous body plan.
