The penicillate genus Unixenus Jones, 1944 is widespread, with species found in Africa, Madagascar, India and Australia. Each of the two Australian species was originally described from single samples from Western Australia. In this study, collections of Penicillata from museums in all states of Australia were examined to provide further details of the two described species, to revise the diagnoses for both the genus and the species, and to better understand the distribution of the two species in Australia. In addition, two new species Unixenus karajinensissp. n. and Unixenus corticolussp. n. are described.  相似文献

A chromatographic method involving medium-pressure liquid chromatography on alumina impregnated with silver nitrate is described for the separation of a series of closely related C27 sterol precursors of cholesterol differing only in the number and location of olefinic double bonds. The features of the described system are compared with those of previously described thin-layer, gas-liquid, gravity column, and high-pressure liquid chromatographic methods.  相似文献

Two brothers are described with a severe syndrome of postnatal growth and mental retardation which includes extreme microcephaly, obesity developing during infancy, microgonadismsm, and a characteristic amphora-shaped facies. The neurological exam is highly abnormal, with hypertonia and hyperreflexia, nystagmus, and an extremely irritable and agitated behavior. The first child, who died at 4/1/2 years, also presented neonatal hypoglycemia and chronic constipation. Although the etiology of this syndrome is unknown, it is tempting to consider an X-linked recessive gene, given the importance of the X chromosome in mental retardation. Among the over 70 syndromes of X-linked mental retardation already described, our patients resemble individuals with the B?rjeson-Forssman-Lehmann (BFL) syndrome the most. However, the severity of their dwarfism and mental retardation is much greater than described in any BFL patient to date, and the neurological and dysmorphic features vary significantly from those described in the BFL. Although a particularly severe variant, perhaps allelic, is a possibility, an as yet undescribed disorder is also plausible, the etiology of which would probably be recessive, either autosomal or X-linked.  相似文献

Fossil beetles are described from Kedrovka beds of the locality Babii Kamen’, Kuznetsk Basin, Siberia. According to different authors, this locality is dated to the terminal Permian or basal Triassic. SEM studies have shown that Ademosynoides asiaticus Martynov, 1936, described from this locality, should be placed in the family Trachypachidae, which makes it the earliest known extant family of beetles. In addition to the re-studied holotype, further material is described for this species; a new species of the same genus and a new genus and species of the same family are also described. As a result, almost 10% of the 78 beetle fossils known from this locality are identified as belonging to Trachypachidae. Unfortunately, the study of these beetles is complicated by the rather poor preservation quality and very small size of the majority of the fossils, which usually cannot be properly studied without using SEM. However, even in this case there is no full certainty that the results are absolutely reliable.  相似文献

Twenty-three species of Conus were described by authors other than Linnaeus between 1766 and 1786. Of these, 3 are Eocene species from England described by Solander in Brander (1766), and the remainder are Recent. Chemnitz (1777) described one valid species. Of the 10 species described by Born (1778), 7 are valid, 2 are junior synonyms of Linnaean species, and 1 is a nomen dubium. Solander in [Lightfoot] (1786) described 5 species, of which 3 are valid and 2 are junior synonyms of Linnaean species. Lightfoot (1786) described 4 species, of which 1 is valid and 3 are junior synonyms of Linnaean species.
Holotypes of 7 species and lectotypes of 3 species exist, and representatives of lecto-types of 10 species have been selected. All of these types are illustrated photographically.
Between 1758 and 1786, 60 species of Conus were described, of which 45 are now considered valid. Of these, 42 are Recent.  相似文献

Casale A 《ZooKeys》2011,(100):47-54
Calleida desenderi Casale, sp. n., is described from Ecuador, Napo Province, surroundings of San Rafael. The new taxon is mostly characterized by the head and appendages rufous, the disc of elytra with marked metallic green reflection, the median lobe of aedeagus ring-like, and the endophallus with a long, twisted flagellum. A key for identification of the closer Neotropical species described so far is also provided.  相似文献

The Permian terebratulids of Eurasia are revised. The taxonomic composition of the Permian terebratulids of the Russian Platform, Northern Caucasus, Transcaucasia, northern and southeastern Pamirs, and northern China (Inner Mongolia) is elucidated. Fifty-one species (13 described here as new), 21 genera (3 described here as new), 7 families, and 6 superfamilies are described. During the progress of the study, the author (Smirnova, 2004a, 2004b, 2006a, 2006b) and Smirnova and Grunt (2002, 2003a, 2003b) described for the first time 19 species, nine genera, two families, and one superfamily. Morphofunctional analysis reveals a great diversity of internal structures, of the time of their appearance in the ontogeny, and of their taxonomic significance. Ontogenetic study reveals phylogenetic relationships between the Permian and Meso-Cenozoic terebratulids, the presence of the superfamilies Terebratuloidea and Loboidothyroidea in the Permian, and a new type of brachidium ontogeny characterizing the superfamily Compositelasmatoidea. This book is intended for paleontologists and biologists interested in problems of taxonomy and phylogeny, and includes 5 plates, 80 figures, and 75 bibliographic references.  相似文献
