A New Species

The classification of the Trematode family Opisthorchiidæ presents some difficulties to the systematist. These difficulties arise partly from the fact that a number of the existing species appear to lack any real morphological characters by which they can be differentiated, slight variations in measurements, together with a difference in host, having been considered sufficient to justify the making of new species. This view has resulted in the placing of undue importance on somewhat minor differences when they do occur in other species, such differences being considered sufficient for creating new genera.The systematist is further confronted with the difficulty of forming definite opinions on the systematic position of some of the species made by earlier workers. Their descriptions and figures are often inadequate owing to the fact that characters which, in the past, were considered of minor importance are now given much closer attention. Examples of the confusion which has arisen from such a position will be referred to in this paper.

Three New Species

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.

A New Species

The taxonomy of Babina sensu lato was controversial in the past decades. In this study, the phylogeny of genus Babina sensu lato was re-constructed based on genetic analysis, morphological comparison and advertisement call analysis. We found that Babina sensu stricto and previous subgenus Nidirana should be two distinct genera in the family Ranidae. N. caldwelli is confirmed to be a synonym of N. adenopleura because of the small genetic divergence and the lack of distinct morphological differences. A new species, Nidirana nankunensis sp. nov. is described based on a series of specimens collected from Mt. Nankun, Guangdong Province, China, which can be distinguished from other known congeners by having a behavior of nest construction, distinctive advertisement calls, significant divergence in the mitochondrial genes, and a combination of morphological characters. Currently, the genus Babina contains two species and the genus Nidirana contains eight species.

A New Species

The Afrotropical species described as Trachyphloeini Lacordaire, 1863 were examined and their taxonomic status is revised. Atrachyphloeus Voss, 1962 is proposed as a junior synonym of Phaylomerinthus Schoenherr, 1842, Cathormiocerus africanus Hoffmann, 1965 as a junior synonym of Tapinomorphus sylvicola Voss, 1962 and Trachyphloeus pustulifer Voss, 1959 as a junior synonym of Platycopes tuberculatus Marshall, 1906. Atrachyphloeus convergens Voss, 1962 is transferred to the genus Phaylomerinthus Schoenherr, 1842, Trachyphloeus hardenbergi Marshall, 1923 and T. notulatus Boheman, 1842 to Glyptosomus Schoenherr, 1847, Trachyphloeus nanus Fåhraeus, 1871 to Pentatrachyphloeus Voss, 1974, Trachyphloeus pustulifer Voss, 1959 to Platycopes Schoenherr, 1823 and Trachyphloeus setiger Fåhraeus, 1871 to Phaylomerinthus Schoenherr, 1842. “Trachyphloeosoma” brevicolle Voss, 1974, “Trachyphloeus” brevis Boheman, 1842, “T”. nodifrons Hoffmann, 1968 and “T”. squalidus Boheman, 1842 are provisionally left in their current genera, but new genera for them will be described in future papers. The genus Phaylomerinthus Schoenherr, 1842 has been redefined and redescribed. Lectotypes for the following species are designated (current names added in brackets where different): Cathormiocerus africanus Hoffmann, 1965 (Tapinomorphus sylvicola Voss, 1962), Trachyphloeus hardenbergi Marshall, 1923 (Glyptosomus hardenbergi (Marshall, 1923)), Trachyphloeus nanus Fåhraeus, 1871 (Pentatrachyphloeus nanus (Fåhraeus, 1871)), Trachyphloeus notulatus Boheman, 1842 (Glyptosomus notulatus (Boheman, 1842)), Trachyphloeus pustulifer Voss, 1959 (Platycopes tuberculatus (Marshall, 1906)), Trachyphloeus setiger Fåhraeus, 1871 (Phaylomerinthus setiger (Fåhraeus, 1871)), “Trachyphloeus” brevis Boheman in Schoenherr, 1842 and “Trachyphloeus” squalidus Boheman in Schoenherr, 1842. Two paralectotypes of Cathormiocerus africanus Hoffmann, 1965 from Tanzania are described as a new species, Tapinomorphus franzi sp. n. All type specimens are illustrated.

A New Species

Phymaraphiniidae Schrammen 1924 (Porifera: Astrophorina) is a family of lithistid demosponges that has received little attention in the past decades. The systematic problems within this family have not been addressed for a long time due to the absence of new records and material. The genus Exsuperantia Özdikmen 2009 was first described by Schmidt (1879) as Rimella to allocate the species Rimella clava, found in the Caribbean. In 1892, Topsent found what he thought to be the same species described by Schmidt in the Azores, and synonymized it with Racodiscula clava, as he thought this species belonged to the family Theonellidae Lendenfeld 1903. However, Rimella and Racodiscula belong to distinct families: Rimella to Phymaraphiniidae, and Racodiscula to Theonellidae. Due to the fact that the genus Rimella was already preoccupied by a gastropod, it was renamed as Exsuperantia. In result of the poor preservation of Schmidt’s material and the absence of new specimens, the attribution of Topsent’s specimens to the family level remained obscure. Here, we review the genus Exsuperantia based on the analysis of new material recently collected during various research expeditions in the northeast Atlantic Ocean. The comparison of these new specimens with Schmidt’s and Topsent’s type material, allowed us to assign Topsent’s specimens to a new species, Exsuperantia archipelagus sp. nov., and confirm its attribution to the family Phymaraphiniidae (not Theonellidae). Phylogenetic reconstructions using newly generated sequences of the cytochrome subunit (COI) marker also support the assignment of the new species to the family Phymaraphiniidae (not Theonellidae).

This research presents three new species of carnivorous sponges from the family Cladorhizidae from the Great Australian Bight, South Australia. This research also shows a clear separation within the species currently known as Cladorhiza into those with an arbuscular or tree-like morphology from the Atlantic, to those of differing morphologies and propose three new genera, i.e. Bathytentacular gen. nov., Abyssosdiskos gen. nov. and Nullarbora gen. nov. and the resurrection of an old genus Axoniderma. nov. The three new species described in this paper are Nullarbora heptaxia sp. nov., Abyssocladia oxyasters sp. nov. and Lycopodina hystrix sp. nov. A new species in the family Guitarridae, Guitarra davidconryi sp. nov., a family closely related to the carnivorous sponges is also described in this paper. These new species are the first recorded carnivorous species from South Australia and increase the number of species recorded from around Australia to 25.

A New Species

The genus Biscogniauxia is paraphyletic to members of the family Xylariaceae and includes at least 52 species to date that are mainly pathogens of dicotyledonous angiosperm trees. Most of these are forest trees, such as those in the genera Acacia, Acer, Alnus, Eucalyptus, Fraxinus, Populus, and Quercus, and other species of minor importance. Biscogniauxia spp. have been reported as endophytes or secondary invaders that attack only stressed plants. During a survey in rosaceous orchards in southern Italy, several charcoal cankers were observed and stroma samples were collected. A collection of 31 Biscogniauxia isolates was analyzed. Their phylogenetic relationships were determined through study of the internal transcribed spacer, β-tubulin, and actin gene sequences. Combining morphological, cultural, and molecular data, a new species of Biscogniauxia is described here as Biscogniauxia rosacearum. This new species was isolated for the first time from rosaceous hosts in Apulia. Pathogenicity tests showed that it causes symptoms on stems when artificially inoculated and produces stromata on the bark surface.
