Molecular phylogeny and systematics of Australian and East Timorese Stenothyridae (Caenogastropoda: Truncatelloidea)

The Australian and East Timorese species belonging to the truncatelloid family Stenothyridae are revised using molecular data and morphological characters from the shell, operculum, radula and external and reproductive anatomy. The Australian species Stenothyra australis is redescribed and two previously recognised subspecies are shown to be synonyms. The New Guinean species Stenothyra paludicola van Benthem Jutting, 1963 Benthem Jutting, W.S.S. van (1963) Non-marine Mollusca of West New Guinea. Part I: Mollusca from fresh and brackish waters. Nova Guinea, Zoology 20, 409–521. [Google Scholar] is redescribed and recorded from the Torres Strait region of northern Australia, and two new subspecies of S. paludicola are described from the Northern Territory and East Timor; S. paludicola topendensis n. subsp. and S. paludicola timorensis n. subsp. respectively. Stenothyra gelasinosa n. sp. is described from Australia, comprising three allopatric subspecies; S. gelasinosa gelasinosa n. sp. and n. subsp. from the eastern seaboard, S. gelasinosa phrixa n. subsp. from northern Australia and S. gelasinosa apiosa n. subsp. from the Pilbara region of Western Australia. Stenothyra frustillum is considered a nomen dubium. Molecular phylogenetic analysis of these taxa and other Asian stenothyrids supports these systematic decisions and provides a preliminary interpretation of relationships within Stenothyridae.     

Small‐scale genetic structuring in a tropical cave snail and admixture with its above‐ground sister species†

We analyse the phylogeographical structure in the cave snail Georissa filiasaulae Haase & Schilthuizen, 2007 (Gastropoda: Hydrocenidae) and its above‐ground sister species G. saulae (van Benthem‐Jutting, 1966) at limestone outcrops in Sabah, Malaysian Borneo. Morphometric and 16S mitochondrial DNA data for some 220 individuals reveal strong morphological differentiation, despite ongoing unidirectional gene flow from the epigean into the hypogean environment, strong, small‐scale genetic structuring within the cave and underground dispersal between caves that were previously thought to be isolated. We discuss these results – which constitute the first phylogeographical analysis of a terrestrial cave snail – in the light of speciation in cave organisms and across ecotones in general. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, 105 , 727–740.     

Panbiogeography and rails of the genus Gallirallus

Abstract

An investigation of flightlessness in the Rallidae led me to question the theories of Olson (1973); that all rails in the genus Gallirallus were distributed over their present range by recent flighted dispersal; and that flightlessness is a recent process conferred by the paedomorphic process neoteny. The current distribution of some members of Gallirallus (Olson 1973a) are interpreted using the panbiogeographic method of Croizat (1958, 1958a). This method indicates that the distribution of some rails is similar to other biota. I suggest the group may be ancient, and its distribution the result of vicariism. Consequently, the evolution of flightless morphology need not be fast, and the flightless rails on different land masses could be the result of flightless radiations.     

A peculiar new species in the genus Landouria Godwin-Austen, 1918 from China (Gastropoda: Heterobranchia: Stylommatophora: Camaenidae)

Landouria omphalostoma n. sp. is described from northern Yunnan, China. The new species is placed in the genus Landouria Godwin-Austen, 1918 based on the presence of tuberculated flagellum and swollen basal part in the bursa copulatrix, and on the absence of dart sacs and mucous glands. L. omphalostoma n. sp. is characterized by a horizontal aperture of the shell which is unique in the genus. This feature resembles those of only two other camaenid/bradybaenid taxa, species of the Chinese genus Pseudaspasita Möllendorff, 1902 and species of the Japanese genus Coelorus Pilsbry, 1900. This is the first verified record of the genus in China and the easternmost record of Landouria. This paper provides the taxonomic ground work for further studies of the repeated evolution of a horizontal aperture.     

Preliminary notes on the genus Aeschnosoma Selys 1870 (Odonata: Anisoptera: Corduliidae s. str.)

Three new species of the genus Aeschnosoma are briefly described and illustrated. A. pseudoforcipula n. sp. and A. heliophila n. sp., both from the Brazilian Central Plateau are respectively related to the two Amazonian species A. forcipula Hagen in Selys 1871, and A. auripennis Geijskes 1970. A. louissiriusi n. sp. from Northern Brazil is not closely related to any known species. Based on larval and adult derived characters, the genus Aeschnosoma appears closely related to the Australian genus Pentathemis Karsch 1890, and also to the Madagascan genus Libellulosoma Martin 1907. The clade Aeschnosomata nov. is erected to receive the three genera. Some putative plesiomorphies would place this clade sister group of the remaining Corduliidae s.str.     

The genus Troglophilus Krauss, 1879 (Orthoptera: Rhaphidophoridae) in the west Balkans

We present a revision of the genus Troglophilus in the western part of the Balkan Peninsula based on morphological and genetic analysis, and provide distribution data for the species. The results of these analyses reduced the number of the known taxa within the genus Troglophilus in this area to five valid species: Troglophilus cavicola ( Kollar, 1833 ), Troglophilus neglectus Krauss, 1879 , Troglophilus ovuliformis Karny, 1907 , Troglophilus brevicauda Chopard, 1934, and Troglophilus lazaropolensis Karaman, 1958. A new species Troglophilus zorae sp. nov. is described and Troglophilus neglectus serbicus Maran, 1958, Troglophilus neglectus vlasinensis Maran, 1958, Troglophilus bukoviki Karaman, 1968 and Troglophilus pretneri Us, 1970 are synonymized. The distribution pattern of the western Balkan species supports a general east?west migration route. We also determined the centres of origin and spreading directions of particular species according to the distribution of the taxa and the structure of the haplotypes. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163 , 1035–1063.     

The wine yeasts of the Cape

Summary Ascospore formation has been observed in three species of the genusBrettanomyces, viz. Brett. bruxellensis. Brett, intermedius andBrett. schanderlii. On media of adequate vitamin content these species form 1–4 hat-shaped ascospores. The spores are liberated rather soon after maturation. Heat treatment of ascogenous cultures indicated that these species are homothallic. In view of the fact that ascospore formation has been observed in the type species,Brett. bruxellensis, the transfer of the genus to theEndomycetaceae should be considered.

Tropidofusus ypotethys: a new genus and new species of Columbariidae (Mollusca: Gastropoda: Turbinelloidea)

ABSTRACT

The genus Tripidofusus n. gen. is proposed to include Tropidofusus ypotethys n. sp. from bathyal depths off New Zealand, as well as Fulgurofusus aequilonius and Columbarium benthocallis from the abyssal zones of the Bering Sea and Scotia Sea, respectively. Tropidofusus can be distinguished from both Fulgurofusus and Coluzea on the basis of its lower spire, prominent peripheral keel, long, thin siphonal canal, as well as in having a much thinner shell that lacks axial sculpture. The type species, Tropidofusus ypotethys n. sp., differs from its congeners in having a broader peripheral keel, smaller aperture and longer siphonal canal, as well as by inhabiting bathyal rather than abyssal depths. The genus is reviewed and the relationships of Tropidofusus to other supraspecific taxa within Columbariidae are discussed, as are relationships among the families within Turbinelloidea.

A STUDY ON GENUS INDOMEGOURA (HOMOPTERA: APHIDIDAE) AND NOTES ON NEW SPECIES*

Abstract The genus Indomegoura Hille Ris Lambers, 1958 was inveatigated in this paper. One new species I. crassirostra Qiao and Zhang was described. Based on the study of all four known species (including the new species above), a key to species was given. According to the geographical distribution of the genus and phytogeographical of host plants, the recent differentiation center of this genus could be located in Center China sub-region, Oriental Realm. All the specimens examined are deposited in Institute of Zoology, Academia Sinica.     

Taxonomic revision and phylogeny of the genus Aneorhachis Kleine 1923 (Coleoptera: Brentidae: Microtrachelizini)

A taxonomic revision of the genus Aneorhachis Kleine 1923 (Coleoptera: Brentidae) and a phylogenetic analysis of species belonging to this genus are carried out. The genus Ipsopisthius Kabakov 2001 is synonymised with Aneorhachis, and two new combinations are proposed: Aneorhachis hirta (Kabakov 2001), n. comb. and A. incerta (Kleine 1935), n. comb. Higonius nitens Goossens 2008 is synonymized with A. incerta. One new species is described from New Guinea, A. papuana n. sp. All the species are redescribed and type-specimens are illustrated; an identification key is proposed. A maximum parsimony analysis is provided on the base of 23 characters from adult morphology. This analysis confirms the monophyly of the genus and seems to show that Aneorhachis originated on continental Asia and then spread out eastward to colonize Pacific islands.     

Contributions to relational biology

The principle of biotopological mapping (Rashevsky, 1954,Bull. Math. Biophysics,16, 317–48) is given a generalized formulation, as the principle of relational epimorphism in biology. The connection between this principle and Robert Rosen’s representation of organisms by means of categories (1958,Bull. Math. Biophysics,20, 317–41) is studied. Rosen’s theory of (M,R)-systems, (1958,Bull. Math. Biophysics,20, 245–60) is generalized by dropping the assumption that only terminalM _i components are sending inputs into theR _i components. It is shown that, if the primordial organism is an (M,R)-system, then the higher organisms, obtained by a construction well discussed previously (1958,Bull. Math. Biophysics,20, 71–93), are also (M,R)-systems. Several theorems about such derived (M,R)-systems are demonstrated. It is shown that Rosen’s concept of an organism as a set of mappings throws light on phenomena of synesthesia and also leads to the conclusion that Gestalt phenomena must occur not only in the fields of visual and auditory perception but in perceptions of any modality.     

Splitting Asperula (Rubiaceae): a proposal for consistency purposes within sections Cynanchicae,Thliphthisa and Hexaphylla

Abstract

Authors report 139 new nomenclatural combinations in the sections Cynanchicae, Thliphthisa and Hexaphylla of the genus Asperula L. (Rubiaceae). These changes were deemed necessary as a consequence of numerous molecular phylogenetic studies which have provided abundant evidence on the polyphyletic nature of the genus. As the complete species-level phylogeny of the tribe Rubieae, and especially, of the genus Galium L. is not available as yet, the authors preferred to instigate changes only in the sections of Asperula whose phylogenetic position is deemed stable.     

Allolarinus,a new genus and species of Lixini (Coleoptera: Curculionidae: Lixinae) from Congo

A new weevil genus, Allolarinus n. gen., with type species, Allolarinus demeyeri n. sp., is described from Congo in the tribe Lixini. The illustrations and diagnostic characteristics of this genus have been presented in a table and figure plates. This new genus is related to Larinus Dejean in terms of the type of elytra and general shape of the prothorax but clearly differs from Larinus with respect to its tooth-bearing femora and granulose pronotum. The trapezoidal short-neck prothorax and general shape of the elytra of this new genus are similar to those of Larinus; the granulose pronotum to that of Lixomorphus Faust; the dentate femora to that of Holcolixus Voss, Erilixus Voss, and Sublarinus Petri; while the existing cubito-anal vein on metathoracic wings to those of Allolixus Voss.     

Pselaphotumulus,a new genus of pselaphine endemic to New Zealand (Coleoptera: Staphylinidae: Pselaphinae: Pselaphitae)

ABSTRACT

Pselaphotumulus Owens and Carlton, gen. nov., is described as the sixth genus in the tribe Pselaphini known from New Zealand. Three new species are described: Pselaphotumulus aorerei, sp. nov., Pselaphotumulus dubius, sp. nov. and Pselaphotumulus unus, sp. nov.. Three species, Pselaphus cavelli (Broun 1893), Pselaphus oviceps (Broun 1917) and Pselaphus urquharti (Broun 1917) are transferred to Pselaphotumulus, nov. combs. Lectotypes from type series in the New Zealand Broun Collection (Natural History Museum, London) are designated for these three species. Habitus photographs, distributional maps and line drawings of diagnostic characters are provided for each species. A key to species is provided. Searches of museum collections have not yielded representatives outside of New Zealand, suggesting that this is the first endemic genus in the tribe Pselaphini described from the New Zealand’s main islands, specifically, the South Island. Pselaphotumulus species exhibit restricted distribution patterns that approximately coincide with the Pacific/Indo Australian Plate boundary.     

Revision of the genus Adorodocia Brenske 1893 (Coleoptera: Scarabaeoidea: Rutelinae: Adoretini) endemic to Madagascar

Summary. The Adoretini of the Malagasy endemic genus Adorodocia Brenske 1893 is revised. Fourteen new species and one new subspecies are described and compared with their most closely related species: A. constricta n. sp., A. cuccodoroi n. sp., A. flava n. sp., A. liliae n. sp., A. marginata n. sp., A. peyrierasi n. sp., A. pseudoconstricta n. sp., A. pseudoflava n. sp., A. pseudostrigata n. sp., A. recta n. sp., A. robusta n. sp., A. sogai n. sp., A. vadoni n. sp., A. viettei n. sp. and A. vittaticollis flavipes n. ssp. The synonymy between Adoretus strigatus Waterhouse 1878, and Pseudadorodocia aenigma Arrow 1901, is confirmed. Thus, based on the results of this study, the genus Adorodocia includes 16 species, and one of them is represented by two subspecies. Diagnostic characters to separate the species in the genus deal mostly with the shape of parameres, color of body and legs, shape of pronotum and female eighth tergite, setation of pronotum and elytra. Key to species, diagnoses and distribution for each species are provided. Endophallus and female genitalia are illustrated for the first time for this genus.     

A revision of genus Atalophlebioides (Ephemeroptera: Leptophlebiidae)

Abstract

Atalophlebioides Phillips is redescribed as a monotypic genus endemic to New Zealand. All life stages of A. cromwelli (Phillips) are described, and a lectotype is designated. The relationships of the genus and the ecology of A. cromwelli are discussed.     

Taxonomic reconsideration of the genus Chorioptes Gervais and van Beneden, 1859 (Acari: Psoroptidae)

The present review of the literature on mites of the genus Chorioptes Gervais and Van Beneden, 1859 argues for a support of the validity of C. bovis (Hering, 1845) and C. texanus Hirst, 1924 based on biological, morphological and molecular genetic studies. However, the validity of three further species, C. crewei Lavoipierre, 1958, C. mydaus Fain, 1975 and C. panda Fain and Leclerc, 1975, is regarded as questionable because discriminations of mites, which were described as isolated cases only, were based on morphological features while transfer or cross-breeding studies were not done.
