Phylogeny and biogeography of the genus Pseudectinosoma, and description of P. janineae sp. n. (Crustacea, Copepoda, Ectinosomatidae)

Recent stygobiological investigations carried out in the circum-Mediterranean area resulted in the discovery of a new species of the genus Pseudectinosoma Kunz, described herein as P. janineae sp. n. The taxonomic status of the genus is reviewed in a phylogenetic perspective. The origin of the present-day distribution of the genus Pseudectinosoma is reconstructed both from patterns of relationships among the species and from palaeogeographical data.     

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.     

THE GENUS HYPOGLOSSUM KÜTZING (DELESSERIACEAE,RHODOPHYTA) IN THE TROPICAL WESTERN ATLANTIC,INCLUDING H. ANOMALUM SP. NOV.1

Observations are made on the occurrence and distribution of the red algal genus Hypoglossum Kützing (Delesseriaceae, Ceramiales) in the tropical western Atlantic. In addition to the type of the genus, H. hypoglossoides (Stackh.) Coll. & Herv., three other species are reported: H. anomalum sp. nov., H. involvens (Harv.) J. Ag., and H. tenuifolium (Harv.) J. Ag. A key is presented to distinguish these four species. The newly described species, H. anomalum, is like other species in the genus in that its branches arise endogenously from the primary axial row but it is unique in that the branches emerge from the parent blade at some point between the midline and the margin of the blade. The new species is reported from Puerto Rico and Florida.     

On Dysosma Woodson and Sinopodophyllum Ying,gen. nov. of the Berberidaceae

1. A classification is made on seven species of the genus Dysosma, of which four are proposed as new combinations, and one as new species. 2. The pollens of six species in the genus Dysosma and two species of Podophyllum are examined. Morphologically, the Asiatic. P. emodi is radically distinct from the North American P. peltatum and can be separated from Podophyllum as an independent genus-Sinopodophyllum. 3. The trend of evolution in Dysosma (fig. 2)and its relationships with the genera Sinopodophyllum and podophyllum are discussed. 4. Based on the evidence from an analysis of the ecology and geographical distribution of the component species (fig. 3), the problem of the centre of development of the genus Dysosma has been discussed.     

Description of Scalithrium n. gen. (Cestoda,Tetraphyllidea) with Scalithrium minimum (Van Beneden, 1850) n. comb., a parasite of Dasyatis pastinaca (Elasmobranchii,Dasyatidae), as type species

Scalithrium gen. n. (Cestoda, Tetraphyllidea) is proposed with Scalithrium minimum (Van Beneden, 1850) n. comb., parasite of Dasyatis pastinaca (Elasmobranchii, Dasyatidae) as type-species. The new genus Scalithrium (Tetraphyllidea, Phyllobothriidae, Rhinebothriinae) is erected for several species previously included in the genus Rhinebothrium. These species have a scolex with four bothridia, the distal surface of which is divided by transverse septa in a single row of loculi. Scalithrium minimum (Van Beneden, 1850) n. comb. is redescribed from specimens collected from the type-host Dasyatis pastinaca in Tunisia and becomes the type-species of the new genus. After Braun (1900) Echeneibothrium variabile Van Beneden, 1850 is considered as type-species of the genus Echeneibothrium. Species of Rhinebothriinae to be transferred into the genus Scalithrium are discussed and a key is proposed for the eight species.     

Crassophyllum thessalonicae sp.n. (Octocorallia, Pennatulacea), from the Aegean Sea

A new pennatulacean species, Crassophyllum thessalonicae sp.n. is described from the Mediterranean (North Aegean Sea). This is the first record of a Crassophyllum Tixier-Duri vault, 1961 species from the Mediterranean Sea. The differences between the new species and C. cristatum Tixier-Durivault, 1961, the other known species of the genus, are discussed, and the genus Crassophyllum is critically compared with the other two related genera Pteroeides Herklots, 1858 and Sarcoptilus Gray, 1848.     

On a new trematode, Prohemistomum azimi n. sp. (Trematoda: Cyathocotylidae) from the Egyptian slit-faced bat

Prohemistomum azimi n. sp. is described from one out of four Egyptian slit-faced bats, Nycteris thebaica Geffroy, 1910 captured from Giza, Egypt. The new species is compared with other related species of the genus and its specific diagnosis is outlined. The new species is the first record of the genus Prohemistomum Odhner, 1913 from Chiroptera.     

Multigene phylogenetic analysis of the Trichomonascus, Wickerhamiella and Zygoascus yeast clades, and the proposal of Sugiyamaella gen. nov. and 14 new species combinations

Relationships among species assigned to the ascosporic yeast genera Sporopachydermia, Stephanoascus, Trichomonascus, Wickerhamiella and Zygoascus, and to the associated anamorphic genera Arxula, Blastobotrys, Sympodiomyces and Trigonopsis, were determined from phylogenetic analyses of gene sequences from the nearly complete large-subunit rRNA gene, the mitochondrial small-subunit rRNA gene, and cytochrome oxidase II. The genus Stephanoascus is polyphyletic, resulting in reassignment of two species to the older genus Trichomonascus and the third to Sugiyamaella gen. nov. (type species Sugiyamaella smithiae). The genera Sporopachydermia, Wickerhamiella and Zygoascus appear to be monophyletic. The species Pichia ofunaensis and P. tannicola are proposed for transfer to Zygoascus. Arxula, Blastobotrys and Sympodiomyces are members of the Trichomonascus clade, with the genus Blastobotrys having taxonomic priority for anamorphic states. Trigonopsis variabilis and three species of Candida represent a distinct clade. From the foregoing gene sequence analyses, the new ascosporic genus Sugiyamaella is proposed, as are 14 new species combinations and the new family Trichomonascaceae.     

Catadiscus pomaceae sp. n. (Trematoda, Paramphistomatidae) from Pomacea canaliculata (Lamarck, 1801) (Prosobranchia, Ampullariidae).

Catadiscus pomaceae sp. n. from the intestine of the prosobranch mollusc Pomacea canaliculata (Lamarck, 1801), is described. The host snail was collected from a lenitic biotope belonging to the Riachuelo basin (Corrientes province, Argentina) during 1985-1986. So far the species of the genus Catadiscus Cohn, 1904 have been recorded in amphibians and reptiles. This is the first instance of a species of that genus parasitizing a mollusc.
