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.

PionosyllisMalmgren, 1867 is revised based on a cladistic analysis of the 41 species considered herein as valid, two newly described species in this paper (Basidiosyllis victoriaeandOpisthodonta russelli), 11 species from other genera actually belonging, or related to,Pionosyllis, and 13 syllid species from different subfamilies. The phylogenetic analysis is based on 55 characters; a strict consensus of 1200 equally parsimonious trees (length = 314 steps) was obtained. The clades containing species usually included withinPionosyllisare newly named within the frame of a new Linnean classification of the group (except for one, belonging to another subfamily). The diagnosis ofPionosyllisis emended, and five new genera are proposed:Synmerosyllis,Basidiosyllis,Westheidesyllis,PerkinsyllisandBrevicirrosyllis.ParaehlersiaSan Martín, 2003, proved to be closely related toPionosyllis. Seven species are transferred toOpisthodontaLangerhans, 1879, here emended, and three transferred toNudisyllisKnox & Cameron, 1970 (according to San Martín & Hutchings, 2006).Opisthodonta uraga(Imajima, 1966) comb. nov. andPerkinsyllis longisetosacomb. nov. are redescribed.Pionosyllis compactaMalmgren, 1867,P. styliferaEhlers, 1913,P. giganteaMoore, 1908,P. enigmatica(Wesenberg-Lund, 1950), andNudisyllis magnidens(Day, 1953) comb. nov., are redescribed.Pionosyllis marquesensisMonro, 1939 andP. proceraHartman, 1965 likely belong to the Syllinae, thus they are not treated in the taxonomic account.

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.

Water Surfaces

Water striders and their allies (Hemiptera, Gerromorpha) are familiarinhabitants of water surfaces throughout the world. One of the mostspecies-rich groups is the subfamily Microveliinae (Veliidae) that comprisessmall or very small bugs inhabiting the nearshore areas of stagnant orslow-flowing freshwater. Accumulation of material during the past 30 years hasshown that the Australian fauna of Microveliinae is much richer and morediverse than previously recognised. In the present paper we discuss thegeneric classification of the subfamily and describe three new genera forspecies previously classified in the genus MicroveliaWestwood as well as three other new genera and nine new species. The new taxaare: Drepanovelia, gen. nov. (type-species:Microvelia dubia Hale),D. millennium (NSW, Queensland),D. biceros (NSW), and D. nielseni(Queensland) spp. nov., Lacertovelia hirsuta, gen. etsp. nov. (NSW), Petrovelia, gen. nov.,P. agilis (Queensland) andP. katherinae (NT) spp. nov.,Nesidovelia, gen. nov. (type species:Microvelia howense Hale),Microvelopsis, gen. nov. (type species:Microvelia melancholica Hale),M. exuberans (Queensland) andM. minor (Queensland) spp. nov.,Tarsoveloides brevitarsus, gen. et sp. nov.(Queensland). We also redescribe and give additional Australian records fortwo species of the genus Phoreticovelia D. Polhemus & J. Polhemus. Keys to adults of all species are provided and theirdistributions mapped.

A New Species

In order to establish the phylogenetic relationships and to resolve the natural classification of species in Dothideomycetes, it is necessary to use multi-gene phylogeny as well as morphology. Phaeodothis mori is a new species collected from dead leaves of Morus australis from Chiayi, Taiwan. Maximum parsimony, maximum likelihood and Bayesian analyses were performed based on multi-locus phylogenies of ITS, LSU, SSU and tef1-α to clarify the phylogenetic affinities of the species. Phaeodothis mori is distinguished from the other Phaeodothis species based on distinct size differences in ascomata, asci, ascospores and base pair differences in DNA sequence data. Remarkably, this is the first Phaeodothis species recorded from Morus australis. The new species was compared with the type species of Phaeodothis and a comprehensive description and micrographs were provided.

Anarthrurid tanaidaceans are common in the bathyal zone west of the British Isles and their identification has been difficult. The complex history of the taxonomy and classification of the Family Anarthruridae Lang is summarised and H.J. Hansen s Leptognathia group d from the Ingolf expeditions is transferred to the Anarthruridae. Three known species are re-described (Anarthrurasimplex, Leptognathia latiremis, and L. glacialis). In addition, five new genera are erected and five new species described. A key to their identification is given. Zoogeographic patterns indicate a cold-water fauna north of the Faeroes and Iceland and a separate Atlantic Deep Sea fauna along the Hebrides-Porcupine-Biscay slope.

AbstractSixteen species of lichenicolous fungi are documented fromSiphula-like lichens. Two new genera based on new species are introduced.AmylogallaSuija, Motiej. & Kantvilas, characterized by I+ blue, K/I+ violet vegetative hyphae and ascomatal wall, immersed, cleistohymenial, yellowish to orange ascomata, unitunicate, non-amyloid, 8-spored asci and hyaline, ellipsoid, aseptate ascospores, is described fromParasiphulain Tasmania.SaaniaZhurb., characterized by superficial, stromatic, multilocular ascomata, non-amyloid hymenial gel, persistent periphysoids, bitunicate, non-amyloid, 4(–8)-spored asci and narrowly obovate to ellipsoid, 1(–3)-septate, initially hyaline and smooth-walled, later sometimes brown and verruculose ascospores, is described fromSiphulain South Africa. Four additional species are described as new: two fromSiphula(Cercidospora santessoniiMotiej., Zhurb., Suija & Kantvilas andStigmidium kashiwadaniiZhurb.) and two fromParasiphula(Endococcus hafellnerianusMotiej., Suija & Kantvilas andPyrenidium macrosporumMotiej., Zhurb., Suija & Kantvilas). Additional hosts and/or expanded geographical ranges are reported forAabaarnia siphulicola,Epigloea soleiformis, Plectocarpon gayanumandPyrenidium actinellum. The Southern Hemisphere is the centre of species richness for siphulicolous fungi, with 12 species restricted to this region. Taxa recorded for the Northern Hemisphere areSphaerellothecium siphulae(arctic and boreal) and the subcosmopolitanEpigloea soleiformisandPyrenidium actinellum, both of which are also known from various lichen hosts. The distribution of siphulicolous fungi strongly underpins the current generic classification ofSiphula-like lichens, with five species being confined exclusively toParasiphulaand nine toSiphula. A key to the taxa occurring onSiphulaandParasiphulais provided.

While the Oriental and Neotropical Trypaneids have been the subject in recent times of extensive studies, those of the Ethiopian Region are still almost in the same condition in which they were left by H. Loew in his valuable paper of 1861. Only more recently Prof. Hendel has made an attempt to erect some Ethiopian genera in his general classification of the family; but all these genera are only shortly characterised by means of dichotomic tables, and most of their type-species have been given names as new species, but without any description.

One New Species

The genus-level classification of New World Erythroneurini is revised based on results of a phylogenetic analysis of 100 morphological characters. The 704 known species are placed into 18 genera. Erasmoneura Young and Eratoneura Young, previously treated as subgenera of Erythroneura Fitch, and Erythridula Young, most recently treated as a subgenus of Arboridia Zachvatkin, are elevated to generic status. Three species previously included in Erasmoneura are placed in a new genus, Rossmoneura (type species, Erythroneura tecta McAtee). The concept of Erythroneura is thereby narrowed to include only those species previously included in the nominotypical subgenus. New World species previously included in Zygina Fieber are not closely related to the European type species of that genus and are therefore placed in new genera. Neozygina, n. gen., based on type species Erythroneura ceonothana Beamer, includes all species previously included in the “ceonothana group”, and Zyginama, n. gen., based on type species Erythroneura ritana Beamer, includes most species previously included in the “ritana group” of New World Zygina. Five additional new genera are described to include other previously described North American Erythroneurini: Hepzygina, n. gen., based on type species Erythroneura milleri Beamer and also including E. aprica McAtee; Mexigina, n. gen., based on type species Erythroneura oculata McAtee; Nelionidia, n. gen., based on type species N. pueblensis, n. sp., three additional new species, and Erythroneura amicis Ross; Neoimbecilla, n. gen., based on type species Erythroneura kiperi Beamer and one new species; and Illinigina, n. gen., based on type species Erythroneura illinoiensis Gillette. Five new genera, based on previously undescribed species, are also recognized: Aztegina, n. gen, based on A. punctinota, n. sp., from Mexico; Amazygina, n. gen., based on type species A. decaspina, n. sp., and three additional new species from Ecuador; Hamagina, n. gen., based on type species H. spinigera, n. sp., and two additional new species from Peru and Ecuador; Napogina, n. gen., based on type species N. recta, n. sp., and one additional new species from Ecuador; Perugina, n. gen., based on type species P. denticula, n. sp., from Peru; and Spinigina, n. gen., based on type species S. hirsuta, n. sp., and an additional new species from Peru. Phylogenetic analysis suggests that the New World Erythroneurini consist of three lineages resulting from separate invasions from the Old World.

Orthopteroid Insects

The tribal status of Phlugidini Eichler, 1938, is confirmed. A new definition of the tribe is suggested and the taxonomic relationships among genera related to the tribe are discussed. Two new genera, nine new species and one new combination are described from East Africa, New Guinea, Northern Australia, Sulawesi and Borneo. These new taxa are Phlugidia africana Kevan, Tenuiphlugis Kevan, Tenuiphlugis gressitti (Chopard, 19691, comb. nov., T. maai Jin, T. brittoni Jin, T. malkini Jin, Phlugis sulawesi Jin, P. borneoensis Jin, P. burgersi Jin, P. novaeguineaensis Jin, P. rapax Jin and P. philippina Jin.*There is more than one system dealing with the higher classification of orthopteroid insects (for detail, see Jago 1977; Kevan 1977; Ragge 1977; Rentz 1977; Vickery 1977). Among them, Rentz (1979), Kevan (1982) and Vickery and Kevan (1986) are the major recent representatives of different opinions. The designation of the Phlugidini in this paper follows the system of Vickery and Kevan (1986).
