Summary

The relationships between the genera Colanthura Richardson, Califanthura Schultz, Cruranthura Thomson and Cruregens Chilton are discussed and presented from a cladistic point of view. Of the 17 species known three are described as new, Colanthura bruscai, Colanthura kensleyi and Califanthura lowryi.     

The Mollissima subgroup of fannia Desvoidy,with the description of a new species from Burma and a revised key to species (Diptera: Muscidae)

Synopsis

A comparison of the type-species of the genus Coelomyia Haliday (C. mollissima Haliday) with that of the genus Fannia Desvoidy (F. scalaris Fabricius) shows that these two genera cannot be maintained as equivalent phylogenetie taxa. Coelomyia is synonymized with Fannia and its species placed in Fannia, four new combinations thus being established. The mollissima subgroup is defined and its affinities shown, a new species is described, and a revised key to species is given.     

Some new African Ulopini (Homoptera,Cicadellidae, Ulopinae)

Summary

Two new genera and two new species of Ulopini are described from Africa; the distribution, and some aspects of the evolution, of genera in this tribe are discussed. It is suggested that Ulopa damaspina Dlabola belongs to the genus Moonia Distant and a new synonmy is suggested. In an Appendix the genera and species of the Ulopini are listed according to their geographical distribution.     

Considerations about the genus Pentoniscus Richardson, 1913 (Crustacea: Isopoda: Oniscidea) with description of a new species

The status of the neotropical genus Pentoniscus Richardson, 1913 is reconsidered and a diagnosis of this genus is given. It is shown that Pentoniscus Richardson, 1913 is a valid genus and not a synonym of Philoscia Latreille, 1804 as discussed by Schultz (1968). The type species, Pentoniscus pruinosus Richardson, 1913 is redescribed and for the first time figured in detail. A new species of Pentoniscus Richardson, 1913 is described from Costa Rica, Central America, which differs remarkably from its congeners in being unpigmented and blind.

Plantes Cryptogames de France. Par I. B. H. I. Desmazières. Fasc. XVII. Lille, 1836

Summary

A new genus and species of pilargid polychaete, Litocorsa stremma, is described from silty grounds on the west coast of Scotland. Its relationship to other pilargid genera is discussed. Notes on two other pilargid species and a revised key to the genera of the Pilargidae are given.     

Revision of the sesarmid crab genera Labuanium Serène and Soh, 1970, Scandarma Schubart,Liu and Cuesta, 2003 and Namlacium Serène and Soh, 1970 (Crustacea: Decapoda: Brachyura: Sesarmidae), with descriptions of four new genera and two new species

ABSTRACT

The systematics of the arboreal sesarmid crab genera Labuanium Serène and Soh, 1970 and Scandarma Schubart, Liu and Cuesta, 2003 is revised. Also included is the poorly known genus Namlacium Serène and Soh, 1970, which is morphologically similar to Labuanium and may also be arboreal in habit. The present study restricts Labuanium to its type species, L. politum (De Man, 1887), and congeners are transferred to Scandarma, Geosesarma De Man, 1892, and three new genera established herein: Circulium gen. nov., Shinobium gen. nov. and Mindanium gen. nov. Two new species of Scandarma are described from Papua New Guinea and Madagascar. Sesarma jacquinoti Ortmann, 1894, previously regarded as a synonym of Scandarma gracilipes (H. Milne Edwards, 1853) (comb. nov.), is here shown to be a junior synonym of Sesarmops angustifrons (A. Milne-Edwards, 1869). Labuanium schuetteii (Hess, 1865) is regarded as conspecific with Scandarma gracilipes (H. Milne Edwards, 1853) (comb. nov.) and the lectotype of the latter species (here designated) is also selected as the neotype of the former, making the two names objective synonyms. Material which had been identified as ‘Labuanium finni Alcock, 1900’ by Pretzmann (1984) from the South Andaman Islands is actually the poorly known Geosesarma thelxinoe (De Man, 1908), which is here referred to a new genus, Andamanium gen. nov. Sesarma finni Alcock, 1900 s.s. is herein assigned to Scandarma. Namlacium crepidatum (Calman, 1925), the only species in the genus, is redescribed and figured and compared with Labuanium and Scandarma. Keys to species of Circulium and Scandarma are provided.

Re-evaluation of the fossil Phoridae (Diptera)

I re-evaluated the known fossil phorids after re-examining much of the Baltic amber and Dominican amber fauna. Many extant genera reported from Eocene Chinese and Eocene/Oligocene Baltic amber are actually not present; instead there are representatives of relatively primitive stem-group taxa. A new genus and species of fossil phorid, Limulomyia tyche, based on a male and a limuloid female, is described from Baltic amber. Some changes in the taxonomy of amber phorids are proposed: Pseudometopina Disney is synonymized with Metopina Schmitz (new synonymy), Diplonevra meunieri Brues is transferred to the genus Godavaria Brown (new combination), Protophorites fimbriatus Brues is considered a junior subjective synonym of Protoplatyphora tertiaria Brues (new synonymy) and Phalacrotophora tertiara Statz is transferred to the genus Gymnophora (new combination). The oldest confirmed dates for extant phorid genera are given.     

IX.—The Goniatites named in Martin's “Petrificata Derbiensia, 1809”

Abstract

The International Commission on Zoological Nomenclature has recently published its 1948 decision that the new names in W. Martin's 1793 and 1809 publications on Carboniferous fossils from Derbyshire are invalid at Martin's dates, since the names are not considered to be binominal. The effect of this decision on the names of the type-species of the well-known goniatite genera Goniatites and Gastrioceras is discussed, and the proposed type-specimens are illustrated, as also a second specimen in the case of Gastrioceras.     

A new genus and two new species of Philotarsidae. (Insecta: Psocoptera) from East Africa

Summary

Genus Tarsophilus and its species lineatus and aequabilis (Insecta: Psocoptera: Philotarsidae) are described as new. The specimens, all males, were collected in highland areas of East Africa. The new genus is placed in Philotarsidae rather than Pseudocaeciliidae on characters of hypandrium, phallosome, and lacinial tip. Its position in the subfamily Philotarsinae is justified and it is compared to the other genera of this group on both male and on trans-sexual characters.     

A new genus and species of Ricaniidae from Palaeocene deposits in North Dakota

Summary

A new genus and species, Cotradechites lithinus Fennah, are proposed for a fossil tegmen of a Ricaniid (Homoptera : Fulgoroidea) collected in clay deposits of Latest Palaeocene age near Dickinson, North Dakota. The new genus is considered to be most nearly related to the modern tropical American genera Cotrades and Semestra.     

I.—Notes on the Natural History of East Finmark

Synopsis

A new species of Argyrophylax, parasitic on the Banana Scab-Moth Nacoleia octasema Meyrick, is described and the Oriental and Australasian species of this genus are reviewed; a key is given for their identification. Six species and a subspecies hitherto placed in other genera are here assigned to Argyrophylax, and seven new combinations are established; two specific names are newly placed in synonymy.     

A revision of the genus Heliconema Travassos, 1919, Physalopteridae (Nematoda)

Summary

It is accepted that the genus Ortleppina Schulz, 1927, is a synonym of the genus Heliconema Travassos, 1919.

Five valid species of Heliconema are recognized: H. heliconema, H. ahiri, H. baylisi, H. brevispiculum and H. longissima.

A new species, H. baylisi is described, and H. heliconema, H. brevispiculum and H. longissima are redescribed.     

XLI.—Note on a Megalosaurian tibia from the lower Lias of Wilmcote,Warwickshire

Summary

A new species of Dolichomiris Reuter from India and another from South Africa are described, while costicollis Berg is excluded, bringing the total number of species in the genus to seven. All species are figured and keyed. D. linearis Reuter is recorded from Australia, New Guinea, Indonesia and the New Hebrides. Lectotypes are designated where necessary. A revised key to the genera of Stenodemini is presented.     

The Villa group of genera in Africa and Eurasia with a review of the genera comprising Thyridanthrax sensu Bezzi 1924 (Diptera: Bombyliidae)

Summary

Bombyliidae are particularly abundant in arid regions where the greatest diversity of genera and species is found. The Villa group of genera (Anthracinae, Exoprosopini) are especially well represented in the Saharo-Sindian desert region. Difficulty in segregating genera has resulted from reliance on single key characters. Using a suite of characters, including the spermathecae largely overlooked previously, a key is provided to the eleven known genera in the Old World. The genus Thyridanthrax sensu Bezzi (1924) is reviewed and five genera are recognized: Thyridanthrax Osten-Sacken, Exhyalanthrax Becker, Pachyanthrax François, Veribubo Evenhuis, and Caecanthrax gen. nov. Species are allocated to these genera and new species Pachyanthrax laconae, Veribubo gazella and V. saffra and Caecanthrax auratus are also described.     

LXVII.—The classification of the thecidean brachiopods

Abstract

The evolution and classification of thecidean brachiopods is discussed. The shell-structure of the geologically earlier genera is shown to be of pseudopunctate pattern, that of the later genera punctate. The pseudopunctate Rhaetic Bactrynium is not considered a thecidean, and the Tiassic Thecospira is shown to be a pseudopunctate spire-bearer. The new genera Moorellina, Vermiculothecidea and Eolacazella are proposed, and the species Moorellina prima (Rhaetic) and Bifolium lacazelliforme (Cenomanian) are described. The possibility of a neotenous origin of the thecideans from the strophomenoids is examined, and the nonthecidean genus Gwynia discussed in connection with this. The heterochronous thecidiform genera are grouped as the subfamily Thecideinae, and the series of thecidelliniforms from which the thecidiforms evolved as Thecidellininae, the two together forming the family Thecideidae, which is placed in the superfamily Thecideacea to express the divergence of thecidean evolution from strophomenoids.     

Genus Baseodiscus (Nemertea: Heteronemertea): Molecular identification of a new species in a phylogenetic context

A new heteronemertean, Baseodiscus jonasii sp. nov., is described from Guadalcanal, Solomon Islands. It resembles B. delineatus in inner morphology but can be distinguished from this species by its different colour pattern and differences in the nucleotide sequence of the mitochondrial 16S rRNA gene. The monophyletic status of the genus is investigated by reconstructing the phylogeny of six specimens from four species assigned to this genus, together with 22 specimens from nine other heteronemertean genera, using parsimony and Bayesian analysis. The results imply that Baseodiscus is a monophyletic group while several other heteronemertean genera are non‐monophyletic.
