On the Paleozoic bryozoans of the genus <Emphasis Type="Italic">Ascopora</Emphasis> Trautschold

Based on the study of the neotype and the astogeny of the type specimens of the species Ascopora nodosa (Fischer von Waldheim, 1837), the diagnosis and species composition of the genus Ascopora Trautschold, 1876 are emended. The genus Ascopora and three species out of the five included in this genus—A. nodosa (Fischer von Waldheim, 1837); A. sokolovae Schulga-Nesterenko, 1955; and A. latiaxis Schulga-Nesterenko, 1955—are described. A new genus, Tetrasella gen. nov., with the type species T. blanda sp. nov. is described. This genus comprises five species, transferred from the composition of the genus Ascopora. An emended diagnosis of the genus Ascoporella Krutchinina, 1986, is provided. This genus comprises nine species, of which two, A. lecta sp. nov. and A. mera sp. nov., are described as new species.     

Monophyletic origin of Caryophyllia (Scleractinia,Caryophylliidae), with descriptions of six new species

The genus Caryophyllia Lamarck, 1816 is the most diverse genus within the azooxanthellate Scleractinia comprising 66 Recent species and a purported 195 nominal fossil species. Examination of part of the deep-sea scleractinian collection made by the Paris Museum off New Caledonia and part of the material collected by CSIRO off Australian waters revealed the occurrence of 23 species of Caryophyllia, of which six are new to science. All new records, including the new species, are described, and synonyms, distribution, type locality, type material and illustration are provided for each species. An identification key to all Recent species of Caryophyllia is presented. In addition, the validity of the genus Caryophyllia was investigated by phylogenetic analyses of a dataset consisting of partial mitochondrial 16S rRNA sequences from 12 species assigned to this genus together with seven species representing some of the most morphologically similar caryophylliid genera, and 14 non-caryophyllid species representing 14 scleractinian families. Irrespective of the method of analysis employed, all of the Caryophyllia species formed a well-supported clade together with Dasmosmilia lymani and Crispatotrochus rugosus. Although based on a subset of the Recent Caryophyllia species, these results are consistent with Caryophyllia being a valid genus, but call for a reexamination of Dasmosmilia and Crispatotrochus.

A STUDY ON MINDARUS KOCH IN CHINA WITH DESCRIPTIONS OF NEW SPECIES AND NEW SUBSPECIES (HOMOPTERA: MIN-DARIDAE)*

Abstract This paper deals with the genus Mindam Koch from China. The phylogeny of the genus is discussed. M. keteleerifoliae is regarded as the most advanced species, M. obliquus and M. piceasuc-tus are more advanced than M. abietinus, M. japonicus and M. victoria. The origin centre of the genus may be in Europe and the differentiation centre of the genus may be in Hengduan Mountains Region of China. Geological distribution of the genus shows island-shaped pattern. Five species from China was described in this paper, including one new species, M. piceasuctus Zhang and Qiao, one new subspecies, M. abietinus triprimesensori Zhang and Qiao and one newly recorded species, M. abietinus abietinus Koch 1856. A key to the Chinese species of Mindarus is given. The specimens of five species from China are deposited in the Institute of Zoology, Academia Sinica.     

A record of the Plain Tiger,Danaus chrysippus,in Turkey

Summary

In this publication, a subdivision of the genus Annenica O. Boettger, 1877 sensu Auct. is proposed. One result of our study is the recognition of the genus Sprattia O. Boettger, 1883 for most of the South Anatolian species of the former genus Armenica. The genus Astrogena Szekeres, 1970, which was synonymised by H. NORDSIECK (1975: 98) with Armenica is redefined and used as a subgenus of Armenica for some species. Extensive recent collections contain new species and subspecies of this genus, which are described here.

A new genus of broad-winged moths of the family Cryptolechiidae (Acryptolechia,Lepidoptera, Gelechioidea) from southeastern Asia

The new genus, Acryptolechia (Lepidoptera, Cryptolechiidae), with the type species Cryptolechia malacobyrsa Meyrick, 1921 is described. The differences between this species and the type species of the genus Cryptolechia, Zeller 1852 (C. straminella Zeller, 1852) are shown. The genus Meleonoma Meyrick, 1914 is the closest to the new one. In addition to the type species, the new genus includes Acryptolechia facunda (Meyrick, 1910) comb. n. from India and A. torophanes (Meyrick, 1935) comb. n. from China.     

Relationships and divergence of some taxa of the subfamily Lycodinae (Zoarcidae,Pisces) based on molecular-genetic and morphological data

An integrated molecular-genetic and morphological study of 14 species of 6 genera of Zoarcidae of the subfamily Lycodinae was performed. A high coincidence of study results obtained using both methods was found. The generic independence of the genus Petroschmidtia that includes species P. albonotata and P. toyamensis was justified. It was shown that species L. schmidti and L. nigrocaudatus belong to the genus Lycogrammoides; and the generic status of the genus Bothrocarichthys with species B. microcephalus and of the genus Allolepis with species A. hollandi was restored. The studied taxa fall into three large monophyletic groups that include species of the genus Petroschmidtia, species of the genus Lycodes, and species of the genera Bothrocara, Allolepis, Bothrocarichthys, and Lycogrammoides. Taxa of the last group are characterized by a large complex of morphological differences from the first two groups, including the absence of ventral fins. A key to species and genera of Lycogrammoides and Bothrocarichthys was compiled. The problem of determination of the time of divergence of the studied zoarcid-like fish using the concept of “molecular clock” and its calibration according to paleontological and paleogeographic data is discussed.     

Three new species of gnathostomulida from the West Atlantic

Two new species of Gnathostomulida from Bermuda and one from North Carolina are described. All belong to the higher Bursovaginoidae with two occurring in the genus Austrognathia and one in the genus Gnathostomula. Tables of major diagnostic characters showing morphological variability within species and between previously described species in the same genus are included. Clarification in recognition of Gnathostomula jenneri and Gnathostomula brunidens is given under “Remarks on Known Species”.     

Phylogenetic Relationships of Species of the Genus Kluyveromyces van der Walt (Saccharomycetaceae) Deduced from the Partial Sequences of 18S and 26S Ribosomal RNAs

In order to clarify the phylogenetic relationships of the species classified in the genus Kluyveromyces (Saccharomycetaceae), three partial base sequences of 18S and 26S rRNAs of eighteen strains were determined. The regions determined of the strains corresponded to positions 1451 through 1618 (168 bases) of 18S rRNA and to positions 1611 through 1835 (225 bases) and 493 through 622 (130 bases) of a strain (IFO 2376) of Saccharomyces cerevisiae. The analyses of the partial base sequences suggested that the genus Kluyveromyces is phylogenetically heterogeneous, ranging from the strains that are quite close to the strain of S. cerevisiae to the strains that are distinct enough to be classified in genera separate from the genus Saccharomyces. From our sequence data, we concluded that the extent of the genus Kluyveromyces should be restricted to only one species, K. polysporus, the type species of the genus. Kluyveromyces phaffii was also distinct enough to deserve another genus. Kluyveromyces cellobiovorus was not close to any of the strains of Kluyveromyces species examined, and should be excluded from the genus. Most of the strains of the species examined were fairly close to the strain of S. cerevisiae.     

New data on perittocrinids and hybocrinids (Crinoidea, Echinodermata) from the Middle Ordovician of the Baltic region

Age variation of radial plates of perittocrinids and aberrant cups of the hybocrinid genus Hoplocrinus from the Middle Ordovician of the St-Petersburg region are examined. Three patterns for the development of folds on the radial plates of perittocrinids are recognized. The differences between patterns are of species level. It is proposed here that the folded structures of perittocrinids (as well as the pore-structures of other pelmatozoans) were not only used for respiration, but also very likely for feeding. Tetracionocrinus transitor is a young individual of a species of the genus Perittocrinus or a paedomorphic species of this genus. The study of aberrant cups of Hoplocrinus suggests that its ancestor could have had biserial arms. Phylogenetic implications of this interpretation are discussed, and homologies within the phylum Echinodermata, reassessed. The three-armed genus Baerocrinus may be an aberrant form of a species of the genus Hoplocrinus.

CHROMOSOME NUMBERS IN CUPHEA (LYTHRACEAE): NEW COUNTS AND A SUMMARY

The American genus Cuphea with ca. 260 species is extremely diverse with respect to chromosome number. Counts are now available for 78 species and/or varieties, or 29% of the genus. Included in this study are first reports for 15 taxa from Brazil, Cuba, Dominican Republic, Mexico, and Venezuela. Twenty-two different numbers are known for the genus, ranging from n = 6 to n = 54. The most common number in the primary center of species diversity in Brazil is n = 8, which is regarded as the base number of the genus. Two numbers are most common in the secondary center in Mexico, n = 10 and n = 12. Species with n = 14 or higher are considered to be of polyploid origin. Polyploids comprise 46% of the total species counted and appear in 9 of the 11 sections for which chromosome numbers have been reported. Aneuploid species comprise ca. 25% of the genus and are known from 7 of the 11 sections. The two subgenera are not characterized by different chromosome numbers or sequences of numbers. None of the 14 sections are circumscribed by a single chromosome number. Morphological and ecological variability in widespread, weedy species is correlated with differing chromosome numbers in some species whereas in others the chromosome number is stable. Summary of chromosome numbers by taxonomic section is presented. Section Euandra, centered in eastern Brazil, and the largest section of the genus, appears to be chromosomally most diverse. In section Trispermum, characterized by difficult, variable species with intermediate forms, two of the four species studied have polyploid races. Section Heterodon, endemic to Mexico and Central America and comprising most of the annual species of the genus, is best known chromosomally. Chromosome numbers have been counted for 25 of 28 species, and 12 different numbers are reported. The most advanced sections, Melvilla and Diploptychia, with numerous species occurring at higher altitudes, are characterized by high polyploids. Apomictic species occur in sect. Diploptycia. The cytoevolution of Cuphea is complex with frequent polyploid and aneuploid events apparently playing a significant role in speciation in both centers of diversity.     

Molecular phylogenetics of the burrowing crayfish genus Fallicambarus (Decapoda: Cambaridae)

Ainscough, B.J., Breinholt, J.W., Robison, H.W. & Crandall, K.A. (2013). Molecular phylogenetics of the burrowing crayfish genus Fallicambarus (Decapoda: Cambaridae). —Zoologica Scripta, 42, 306–316. The crayfish genus Fallicambarus contains 19 species of primary burrowing freshwater crayfish divided into two distinct subgenera. We test current hypotheses of the phylogenetic relationships among species within the genus as well as the monophyly of the genus. Our study samples all 19 species for five gene regions (both nuclear and mitochondrial) to estimate a robust phylogenetic hypothesis for the genus. We show that the genus is not a monophyletic group. The subgenus Creaserinus does fall out as a monophyletic group, but distinct from the subgenus Fallicambarus. The subgenus Fallicambarus appears to be monophyletic with the exception of the species Procambarus (Tenuicambarus) tenuis, which falls in the midst of this subgenus suggesting that it might be better classified as a Fallicambarus species. We also show that the species Fallicambarus fodiens is a species complex with distinct evolutionary lineages that are regionalized to different geographic areas.     

A new genus: Sporopachydermia

In two species of the yeast genus Cryptococcus ascospores have been found. A genus is described to accommodate the two species, because the spore wall is extraordinarily thick and its ultrastructure differs from that found in all other yeast genera. The spores are easily liberated from the ascus at maturation. The name Sporopachydermia is proposed for the genus and the names S. lactativora and S. cereana are proposed for the species.
