Marfan Database (third edition): new mutations and new routines for the software.

The Marfan database is a software that contains routines for the analysis of mutations identified in the FBN1 gene that encodes fibrillin-1. Mutations in this gene are associated not only with Marfan syndrome but also with a spectrum of overlapping disorders. The third version of the Marfan database contains 137 entries. The software has been modified to accommodate four new routines and is now accessible on the World Wide Web at http://www.umd.necker.fr     

Paeonia rotundiloba (D. Y. Hong) D. Y. Hong: A new status in tree peonies (Paeoniaceae)

Abstract Paeonia decomposita Hand.‐Mazz. subsp. rotundiloba D. Y. Hong is here raised to the specific rank, P. rotundiloba (D. Y. Hong) D. Y. Hong, based on its distinctiveness of four diagnostic characters: number of carpels; height of disk; number of leaflets of the lower leaves, and shape of the terminal leaflets; and unpublished molecular data. Paeonia rotundiloba differs distinctly from P. decomposita in having carpels mostly 3, less often 2 or 4, very rarely 5 (vs. almost always 5, very occasionally 4 or 3), disk 8–15 mm high (vs. 4–9.6 mm), leaflets mostly 19–39 (vs. 29–63) in number, and ratio of length to width of the terminal leaflets 1.09–1.93 (vs. 1.81–2.99).

A new microsporidian species Glugea mesocotti sp. n. (Microsporidia:Glugeidae) from Mesocottus haitej (Scorpaeniformes:Cottidae)

A new microsporidian parasite of a freshwater fish Mesocottus haitej from the Amur River basin of Russia is described using light microscopy. The numerous whitish xenomas, round or oval, up to 3.0 mm large were found to be located in subcutaneous tissue of the body and mouth cavity, in the intestine and other internal organs. The formol fixed spores are elongate oval, measuring 4.8 (4.5-5.0) x 2.3 (2.2-2.5) microm in a wet smears. Posterior vacuole occupies about half of the spores. Sporophorous vesicles measuring up to 13 microm contain a great number of spores.     

Steinernema ichnusae sp. n. (Nematoda: Steinernematidae) a new entomopathogenic nematode from Sardinia Island (Italy)

A new Steinernema species was isolated from three different sandy soil samples along the Platamona Beach, in the north-west coast of Sardinia Island (Italy). This new species is characterized by the following morphological characters: infective third-stage juvenile with a body length of 866 ± 61 (767-969) μm, distance from head to excretory pore of 63 ± 2.7 (59-68) μm, tail length of 81 ± 3.2 (76-89) μm, ratio E (%) 77 ± 3.4 (68-83); male tail with a mucron only in the second generation, spicule length of 66 ± 1.4 (64-67) μm and gubernaculum length of 44 ± 1.4 (43-46) μm in the first generation male; female of first generation with a slight vulval protrusion and ratio D (%) of 53 ± 4.0 (47-63). The new species differs distinctly from the related species (S. feltiae, S. kraussei, S. litorale, S. oregonense and S. cholashanense) in some morphometric values such as percentage of hyaline portion, ratios of gubernaculum/spicule length, spicule head length/width. The DNA analyses of the internal transcribed spacers and D2D3 regions show that the studied nematode isolates are a new species. Cross hybridisation tests with S. feltiae, S. kraussei, S. litorale, S. weiseri and S. oregonense showed that these species were reproductively isolated.     

A new intraoral flap: facial artery musculomucosal (FAMM) flap.

By combining the principles of nasolabial and buccal mucosal flaps, we have designed a new axial musculomucosal flap based on the facial artery. This flap has been designated the facial artery musculomucosal (FAMM) flap. The flap has proven to be reliable either superiorly based (retrograde flow) or inferiorly based (antegrade flow). It is versatile and has been used 18 times in 15 patients, with one failure and two partial losses. It has been used successfully to reconstruct a wide variety of difficult oronasal mucosal defects, including defects of the palate, alveolus, nasal septum, antrum, upper and lower lips, floor of the mouth, and soft palate.     

A new species of Osteocephalus (Anura: Hylidae) from Guyana.

A new member of the genus Osteocephalus is described from the Pakaraima mountains of western Guyana. This species is the smallest known member of the genus and is probably closely related to O. subtilis. Both share a small size (less than 40 mm snout-vent length), large and bulgy eyes directed somewhat rostrally, green bones, smooth and brownish dorsal skin, relatively short and truncate snout, small tympanum, subgular and laterally expanded vocal sac, poorly developed subarticular and supernumerary tubercles, a supra-anal glandular ridge, and cream-white venter and subocular region. The new species can be distinguished from O. subtilis by the Buff iris (vs black), smaller overall size (32.7 vs 35.8-38.8 mm snout-vent length), relatively larger toe disks, and less developed foot webbing. The cranium of the new species is well ossified, relatively reduced in width between the orbits, without an exposed frontoparietal fontanelle and with the anterior arm of the squamosal extending to about half the distance to the maxillary. The vocal sac is subgularly poorly developed and possess lateral extensions to the area behind the jaw angles. Well developed supraocular and suprasquamosal cartilages give support to the enlarged eyes of this species.     

Sphinctocystis phyllodoces gen. n., sp. n. (Eugregarinida: Lecudinidae)--a new gregarine from Phyllodoce citrina (Polychaeta: Phyllodocidae)

A new species of aseptate gregarine, Sphinctocystis phyllodoces gen. n., sp. n., from the gut of a polychaete Phyllodoce citrina Malmgren, 1865 from White Sea is described. The electron and light microscopic data on trophozoits are presented. Taxonomy of the described species is discussed. Certain ultrastructural characters are included in generic and specific diagnoses. Order Eugregarinida Leger, 1900; suborder Aseptata Chakravarty, 1960; family Lecudinidae Kamm, 1922. GENUS: Sphinctocystis gen. n. TYPE SPECIES: Sphinctocystis phyllodoces sp. n. DIAGNOSIS: Characters of the family. Free trophozoits elongated, often with several annular constrictions. Anterior end asymmetric, without hooks, not separated from the body, with small apical papilla encircled by smooth area. Epicyte "classical", without additional axial formations at the tops of folds; epicytic folds high, monomorphic in cross sections, finger-shaped, with parallel sidewalls. In the gut of polychaetes. DIFFERENTIAL DIAGNOSIS: The new genus differs from Lecudina by having asymmetric anterior end, developed smooth area around the apical papilla, and monomorphic epicytic folds looking finger-shaped in cross sections. It also differs from Lankesteria by the absence of additional axial formations at the tops of the epicytic folds. It differs from both named genera by presence of annular constrictions on the trophozoit body. Sphinctocystis phyllodoces sp. n. DIAGNOSIS: Characters of the genus. Free trophozoits elongated, large, up to 617 x x 77 um. The average height of epicytic folds 976 nm, thickness 194 nm; there are 6-8 apical filaments and rippled dense structures per fold. Nucleus spherical (ellipsoid after fixation), 24-52 microm along longest axis, localised in anterior third of the body, carries several karyosomes of various size; 25-30 nm thick fibrils (possible fragments of nucleolonema) may be present in karyolymph. Other stages unknown. TYPE SERIES: Microscope preparation with 7 trophozoits, Karacci's haematoxylin stained, is kept in the Zoological museum of the Moscow State University (collection number: Z-1). TYPE HOST: Phyllodoce citrina Malmgren, 1865 (Polychaeta: Phyllodocidae). LOCALISATION: Mid-gut.

A new species of blastobotrys: Blastobotrys navarrensis sp. nov. (Hyphomycetes)

A new species of Blastobotrys Klopotek (1, 2, 4, 5) has been recovered from white pepper. It appears to be sufficiently distinct from B. nivea v. Klopotek. (5), B. proliferas Marvanová, and B. aristata Marvanová (2), to be described as a new species under the name of Blastobotrys navarrensis. Both morphological as well as physiological characteristics were taken in account to differentiate the new species from Blastobotrys species known up to date.     

A new family and a new genus for two taxa previously assigned to Apodachlyella completa (J. E. Humphrey) H. Indoh (Peronosporomycetidae: Leptomitales)

DICK, M. VV., 1986. A new family and a new genus for two taxa previously assigned to Apodachlyella completa (J. E. Humphrey) H. Indoh (Peronosporomycetidae: Leptomitales) . At present two distinct taxa are referrable to Apodachlyella completa. New genus and species names (I'lerogone helodes M. W. Dick genus & sp. nov.) are necessary for the taxon reported from the British Isles. Confirmation of the unique wall membranes in the antheridia and oogonia is used to justify the placement of A. completa in a new, monotypic family of the Leptomitales (Apodachlyellaceae M. W. Dick fam. nova). Plerogone is placed provisionally in the Leptomitaceae.
