Three species of the genus Teratorhabditis (Osche, 1952) Dougherty, 1953 collected from sewage and manure samples of North India are described. The species T. andrassyi Tahseen & Jairajpuri (1988) synonymised by Sudhaus (1991) has been reinstated and is characterized by oviparous females having bluntly rounded lips with labial sensilla not raised
beyond labial contour; lip margins and axils heavily cuticularised; three lines in lateral field; considerably wide and tubular
stoma having swollen metastegostomal walls with prismatic inner lining bearing five teeth on each plate; basal bulb with usually
single haustrulum; tail conoid with a terminal spike; eggs with ridged shells and males with 40–45% distally-fused spicules
and a smooth, non-indented bursa having slender papillae in 2/4 + p + 3 configuration. Other populations identified as T. synpapillata and T. palmarum Gerber and Giblin-Davis (1990) are reported for the first time from India. An identification key to species is provided. Relationships within the genus
are discussed.

In this note the taxonomic position of the tiny eomyid genus Keramidomys (Hartenberger, 1967) from the Early/Middle Miocene boundary locality of Sandelzhausen in the Bavarian Upper Freshwater Molasse is reexamined.
As the chronological dating of the Sandelzhausen fossil site has been modified in the past from formerly the Neogene mammal
unit MN6 to now MN5 and thanks to new abundant material this rodent is compared with other European forms. It is shown that
the Sandelzhausen eomyid must be called K. thaleri Hugueney & Mein, 1968 on the basis of several morphological dental differences from K. carpathicus Schaub & Zapfe, 1953. This rodent seems to be an immigrant from East Asia into Europe. Even if K. thaleri is known in many European localities, all correlated to MN5, it is always a rare element of European rodent faunas. Differentiation
from K. carpathicus is not easy and requires a sufficiently large sample.

Summary Seven new names at species rank are proposed in Memecylon sect. Afzeliana Jacq.-Fél., a group of forest shrubs and small trees confined to Guineo-Congolian Africa. The group is centred in Cameroon,
where 17 of the 20 species occur. A new flower type, the “star-flower” in Memecylon is revealed, and its taxonomic and ecological importance discussed. Three new, locally endemic species from the South West
Province of Cameroon are described, mapped and illustrated: M. kupeanum R. D. Stone, Ghogue & Cheek, M. bakossiense R. D. Stone, Ghogue & Cheek, and M. rheophyticum R. D. Stone, Ghogue & Cheek. Two new names, M. accedens R. D. Stone, Ghogue & Cheek and M. hyleastrum R. D. Stone & Ghogue and one new combination, M. mamfeanum (Jacq.-Fél.) R. D. Stone, Ghogue & Cheek are provided at species level for three taxa originally proposed as varieties of
M. afzelii G. Don. The taxon M. arcuatomarginatum var. simulans Jacq.-Fél. is also elevated to species status, as M. simulans (Jacq.-Fél.) R. D. Stone & Ghogue. Conservation assessments are provided for all the newly named taxa. A key is provided
to the species of Memecylon sect. Afzeliana. 相似文献

Summary Three closely affiliated species of Heterospathe Scheff. (H. elegans (Becc.) Becc., H. humilis Becc. and H. versteegiana Becc.) from New Guinea are revised. They are reduced to a single species which is divided into two subspecies, and the new
combination H. elegans subsp. humilis (Becc.) M. S. Trudgen & W. J. Baker is made. The subspecies can be readily distinguished by their growth habit. Epitypes
are designated for the three previously published names, as informative material on the habit is not included in the existing
type specimens. A new, potentially related species is described as H. pullenii M. S. Trudgen & W. J. Baker. 相似文献

The type specimens of platycephalid Platycephalus endrachtensis Quoy and Gaimard 1825 are regarded as being conspecific with Platycephalus arenarius Ramsay and Ogilby 1886, so the latter becomes a junior synonym. This species is characterized as having a caudal fin with four or more longitudinal
dark bands and lacking a yellow blotch. It is also found that Platycephalus westraliae (Whitley 1938), which had been considered to be a junior synonym of Platycephalus bassensis Cuvier 1829, is a valid species. Specimens that recently had been mistakenly identified as “P. endrachtensis,” having the caudal fin with three or four longitudinal dark bands and a yellow blotch on the upper lobe, should be referred
to P. westraliae. 相似文献

Carotenoids are red, yellow and orange pigments, which are widely distributed in nature and are especially abundant in yellow-orange
fruits and vegetables and dark green leafy vegetables. Carotenoids are essential for photosynthesis and photoprotection in
plant life and also have different beneficial effects in humans and animals (van den Berg et al. 2000). For example, β-carotene plays an essential role as the main dietary source of vitamin A. To obtain further insight into
β-carotene biosynthesis in two important economic plant species, Lycium barbarum and Gentiana lutea L., and to investigate and prioritize potential genetic engineering targets in the pathway, the effects of five carotenogenic
genes from these two species, encoding proteins including geranylgeranyl diphosphate synthase, phytoene synthase and δ-carotene desaturase gene, lycopene β-cyclase, lycopene ε-cyclase were functionally analyzed in transgenic tobacco (Nicotiana tabacum) plants. All transgenic tobacco plants constitutively expressing these genes showed enhanced β-carotene contents in their
leaves and flowers to different extents. The addictive effects of co-ordinate expression of double transgenes have also been
investigated. 相似文献

The systematics of the eelpout genus Bothrocara Bean 1890 is reviewed on the basis of 941 specimens. Eight mostly eurybathic, demersal species are recognized, distributed mainly along
the continental slopes of the North and South Pacific oceans, with one species entering the South Atlantic. Distributions
are: B. brunneum ranges from the Sea of Okhotsk to the Gulf of Panama at depths of 199–1,829 m; B. elongatum ranges from the Gulf of Panama to Chile at depths of 720–1,866 m; B. hollandi ranges from the Sea of Japan to the southeastern Bering Sea at depths of 150–1,980 m; B. molle ranges from the western Bering Sea to the South Atlantic at depths of 106–2,688 m; B. nyx is known only from the eastern Bering Sea at depths of 790–1,508 m; B. pusillum ranges from the northern Bering Sea to British Columbia, Canada, at depths of 55–642 m; B. tanakae is found along the northern coasts of Honshu and Hokkaido islands, Japan, at depths of 274–892 m; B. zestum ranges from the Izu Islands, Japan, and central Honshu, Japan, to the Gulf of Alaska at depths of 199–1,620 m (an unidentifiable
specimen from off Taiwan may be B. zestum). The species are distinguished from one another mainly on the basis of head pore patterns, gill raker morphology, coloration
and various meristic and morphometric values. A determination key to the species is provided. 相似文献

Summary Sleumer’s (1971) revision of Casearia (formerly Flacourtiaceae, now Salicaceae) is reviewed to correct the specific delimitation, nomenclature and geography of some of the West and Central African species.
As a result, Casearia inaequalis Hutch. & Dalz. and C. prismatocarpa Mast. are resurrected, the latter to replace C. calodendron Gilg ex Engl. Casearia michelsonii, from the mountains of East Congo (Kinshasa), is described as new. A revised key to the species of West and Central Africa
is presented and their distributions are mapped. 相似文献

Saccocoelium Looss, 1902 is revised and a key to its recognised species is presented. S. obesum Looss, 1902 (type-species) and S. tensum Looss, 1902 are redescribed based on material from Liza spp. (Pisces: Mugilidae) in Spanish Mediterranean and, in the case of the former, Bulgarian Black Sea waters. Two new species,
S. cephali n. sp. and S. currani n. sp., are described from Mugil cephalus L. in Spanish Mediterranean waters. S. gohari Ramadan, Saoud, Ashour & Mansour, 1989b is recognised and commented upon. Lecithobotrys helmymohamedi Ramadan, Saoud, Ashour & Mansour, 1989a, S. portsaidensis El-Shahawi, El-Gindy, Imam & Al-Bassel, 1992, S. saoudi El-Shahawi, El-Gindy, Imam & Al-Bassel, 1992, Neosaccocoelium aegyptiacus El-Shahawi, El-Gindy, Imam & Al-Bassel, 1992 are considered to be synonyms of S. tensum and Neosaccocoelium El-Shahawi, El-Gindy, Imam & Al-Bassel, 1992 a synonym of Saccocoelium. S. obesum, S. tensum and the two new species are compared morphometrically and distinguished by univariate and multivariate analyses. Lecithobotrys mugilis Rekharani & Madhavi, 1985 is transferred to Unisaccus Martin, 1973 as U. mugilis (Rekharani & Madhavi, 1985) n. comb., and Lecithobotrys sprenti Martin, 1973 [= Saccocoelium sprenti (Martin, 1973) Overstreet & Curran, 2005] is transferred to Unisaccus as U. sprenti (Martin, 1973) n. comb. S. megasacculum Liu, Wang, Peng, Yu & Yang, 2004 is transferred to Elliptobursa Wu, Lu & Zhu, 1996 as E. megasacculum (Liu, Wang, Peng, Yu & Yang, 2004) n. comb. S. tripathi Dutta, 1995 (syn. Saccocoelium tripathi Datta & Manna, 1998) is considered to be a species inquirenda.

The invertebrate fauna of many Antarctic ice-free areas, even those close to permanent research stations, can be poorly known.
Here we describe some nematodes from freshwater and saline, marine-derived lakes of the Vestfold Hills, East Antarctica. The
freshwater lakes contained the widespread East Antarctic endemic species, Plectus frigophilus Kirjanova, 1958. The saline lakes were inhabited by two recently described species, Halomonhystera halophila Andrássy, 2006 and Halomonhystera continentalis Andrássy, 2006, and by a new species described in this report, Hypodontolaimus antarcticus sp. n. Originally marine but now brackish Highway Lake contained a nematode fauna with both freshwater and marine-derived
components. The nematode fauna of Antarctica now consists of 54 named species, 22 of which are found in East Antarctica. 相似文献

Marenzelleria bastropi, a new species of Spionidae (Polychaeta) from the brackish water Currituck Sound, North Carolina, is described. The new species
is characterized by the great number of chaetigers between the first neuro- and notopodial hooded hooks, the extension of
the nuchal organ up to the end of chaetiger 2/middle of chaetiger 3 and the presence of about 60–90 branchiate chaetigers.
Marenzelleria bastropi sp. nov. is closely related to M. neglecta (Sikorski and Bick, 2004) and Marenzelleria viridis (Verrill, 1873). Marenzelleria wireni Augener, 1913 is described here for the first time from western Spitsbergen. Adult specimens are investigated and compared with specimens
from other areas of distribution. A key for subadult and adult specimens of all Marenzelleria species is provided. 相似文献

A taxonomic review of the cottid genus Cottiusculus Jordan and Starks 1904 established three species, C. nihonkaiensis sp. nov., C. schmidti, and C. gonez. Cottiusculus nihonkaiensis sp. nov., which had been previously confused with C. schmidti, is described on the basis of 32 specimens (44.8–77.9 mm, SL) collected from the Sea of Japan. The new species is very similar
to C. schmidti in having a curved barbless uppermost preopercular spine and the lateral line extending past the caudal fin base, but is
distinguishable as follows: nasal spines simple or sometimes weakly bicuspid (vs. deeply bicuspid in C. schmidti); first dorsal fin not elongated in either males or females (vs. elongated in males); ventral lateral and lateral line cirri
present (vs. absent). The former is known from the Sea of Japan coasts of Hokkaido, Honshu, Kyushu and the Korean Peninsula,
and Volcano Bay, Hokkaido, and the latter from the Pacific coast of Tohoku District, Japan. Cottiusculus gonez, known from the Sea of Japan, Sea of Okhotsk and Pacific coast of Hokkaido, is characterized by having a simple nasal spine,
the uppermost preopercular spine almost straight with two small cusps dorsally, posterior cusp barbed, and the lateral line
almost reaching to the caudal fin base. A lectotype of C. gonez is designated here. Sequence differences in the cytochrome b gene among the above three species of Cottiusculus are also presented. 相似文献

Summary
Marcetia candolleana A. K. A. Santos & A. B. Martins, is apparently restricted to Mucugê, Bahia (Brazil), where it occurs in areas of campo rupestre vegetation. This new species is closely related to the sympatric M. mucugensis Wurdack, but can be easily recognised by its semi-prostate to procumbent habit, reddish glandular-hirsute indument, loose
and flexuous branches, leaves with inconspicuous reticulation on the abaxial surface, connectives very shortly prolonged below
the thecae, style curved towards the apex, not exceeding the anthers, and pendulous fruit.
