On the basis of external morphology and anatomy, 17 scpeies of the genusSilurus Linnaeus including a new species,S. torrentis from Thailand and Burma, are recognized as valid.S. bedfordi Regan is synonymized withS. asotus, andS. goae Haig is transferred to the genusOmpok. From an anatomical study of 12 species, the diagnostic feature of the genusParasilurus Bleeker is revealed to be invalid, and the genus is synonymized withSilurus. From the phylogenetic analysis, the genusSilurus is divided into two major species groups, thecochinchinensis group which is disributed mainly in Southeast Asia, and theglanis group which is further separated into three subgroups occurring separately in East Asia and Europe. The pattern of distribution
and relationships between ontogeny and phytogeny in the genusSilurus are briefly discussed. 相似文献

Summary A new haploid, homothallic yeast isolated from the larval feed ofXylocopa caffra is described.
A study of its properties shows that the evolution of its sexual and biochemical characteristics has not taken place at the
same rate as in the genusHansenula and the proposed genusDekkeromyces. This led the author to the conclusion that in the yeast domain phylogenetic lines may exist in which a unilateral evolution
of biochemical characteristics has taken place.
At least thre groups of yeasts exist where such discrepancies exist between the evolution of their sexual and biochemical
characteristics. The inclusion of the new species in these groups is discussed.
The new species has provisionally been classified in the genusPichia (in sensu Phaff).
A Latin diagnosis of the species is given. 相似文献

A new yeast species,Bullera piricola, is described. The three strains studied were all isolated from the pear phylloplane. This species differs from allBullera species known at present by forming symmetrical as well as asymmetrical ballistospores. The problem of its integration into
the genusBullera Derx is discussed. An amended diagnosis of the genusBullera is given.

The genusCheirolophus has an interesting western Mediterranean and Macaronesian distribution. Here we investigate the delimitation of the genus and its exclusion from the large genusCentaurea, the systematic position of the related genusPaleocyanus, the delimitation of some species and the phylogeny of the group. We have carried out a phylogenetic analysis of the PCR-generated sequences of the internal transcribed spacers (ITS-1 and ITS-2) of the nuclear ribosomal DNA. The results suggest that the genus, includingPaleocyanus crassifolius is monophyletic; thus, a new combination of this species underCheirolophus is proposed. The Macaronesian group of species is also monophyletic, indicating a single colonization of the archipelago. The poor resolution of microspecies in the Macaronesian group reinforces the hypothesis of a very recent differentiation of the group. 相似文献

A new species ofMarasmius sectionGlobulares, Marasmius brunneospermus sp. nov., found in the lowland forest of Kanagawa and Chiba, Japan, is described and illustrated. This species is characterized
by a hygrophanous pileus with rugulose-reticulate disk, well-developed basal mycelium attached to an extensive mycelial mat
in leaf litter, and conspicuous fusoid-ventricose pleurocystidia. In addition, its brown spore print mottled with white parts
is unusual as an infrageneric character in the genusMarasmius. 相似文献

A new caprellid species, Caprellinoides singularis, is described and illustrated based on the material collected on the Polarstern Cruise ANT XVII/3 from the Branfield Strait. The most striking characteristic of this species is the presence of bilobed
gills on pereonites 3 and 4. The genus Caprellinoides is revised. Caprellinoides antarctica Schellengerg, 1926 and Caprellinoides spinosus Barnard, 1930 are considered junior synonyms of Caprellinoides tristanensis Stebbing, 1888 and Caprellinoides mayeri (Pfeffer, 1888), respectively. The new species, C. singularis, is compared with the remaining species in the genus Caprellinoides: C. tristanensis and C. mayeri, which are illustrated in detail.

Anthocyanins contained in plants belonging to the genusEpimedium in Japan are discussed in this study. Two kinds of anthocyanin, delphinidin 3-p-coumaroyl-sophoroside-5-glucoside (cayratinin) and cyanidin 3-p-coumaroylsophoroside, were identified, and the latter is new to the literature. Only cayratinin was found in the colored
petals of theEpimedium species, but cayratinin and cyanidin glucoside were contained in the stems, young leaves and autumn leaves of all the species
surveyed. 相似文献

Summary A new budding yeast species isolated from soil is described. Its outstanding features are, firstly, the formation of asci
containing up to sixteen long oval to reniform ascospores and, secondly, a fermentative as well as oxidative metabolism. The
assimilation of nitrate is absent and no pseudomycelium is formed.
The taxonomic position of the yeast is discussed and it is pointed out that, due to its exceptional ascospore number (1–16),
it cannot be classified in any of the existing fermentative genera of theEndomycetaceae (in sensu Lodder et Kreger-van Rij). The reniform shape of its ascospores indicates, however, its close relationship with the multispored
genusKluyveromyces, on the one hand, and the newly proposed one to four-spored genusDekkeromyces on the other. The species is provisionally classified as aKluyveromyces species,Kluyveromyces africanus nov. spec., until further information regarding its sexual characteristics becomes available.
By virtue of its more or less intermediate ascospore number, it establishes the direct derivation of the genusDekkeromyces fromDipodascus uninucleatus via the multispored yeast genusKluyveromyces. 相似文献

Detailed studies of various aspects of the morphology and reproduction ofAntithamnion subcorticatum Itono andAntithamnion crouanioides Itono show that these species are incorrectly referred to as the genusAntithamnion. To include these species, a new genus,Balliella, is proposed. In addition, some other algae possibly referable to this genus are briefly discussed. The genusBalliella is here recognized as a member of the new tribeDelesseriopsieae which is most nearly related to the tribe Antithamnieae in the Ceramiaceae. The tribe Delesseriopsieae is now recognized
to include the two genera, i.e.,Delesseriopsis andBalliella. 相似文献

There are 19 species in genusMacaca and some of them are living in sympatry (Fooden, 1980). Although inter-specific hybrids are relatively easy to produce under artificial conditions, hybridization does not
occur naturally. What is preventing that among the species of genusMacaca?
Three rhesus monkeys acquired a discrimination between pictures with rhesus monkeys and without rhesus monkeys. All subjects
showed positive transfer of this discrimination to new pictures with rhesus monkeys and without rhesus monkeys. A further
test showed that these monkeys could discriminate between pictures of rhesus monkeys and pictures of Japanese monkeys. The
results suggest that rhesus monkeys recognize rhesus monkeys as a class, independent of the actual stimuli such as a picture
or an individual monkey.
The ability to recognize members of their own species and the opportunities for such learning may be an important factor preventing
hybridization among the species of genusMacaca. 相似文献
