中国青藓科研究资料(Ⅰ)

根据Handel-Mazzetti 1914至1918年在中国湖南、贵州、云南诸省采集的青藓科标本,1929年V． F. Brotheus发表了青藓科的诸分类群。笔者向赫尔辛基大学植物标本馆借阅了上述类群(8个种、1个 变型)的主模式标本共12份。经过对这些标本逐一鉴定与研究并进行形态指标测量之后,本文订正了部分学名,提出3个新异名。

Mandible and Taxonomy of the Earliest European Homo

Although variability of the mandible makes it problematic for taxonomy, the holotypes of three of the oldest European species, Home georgicus, H. antecessor, H. heidelbergensis, are mandibles. Moreover, the distinctive validity of these three species cannot be established from these particular mandibles. The holotype of H. georgicus is pathological and similar to H. erectus in some important features, while others features are so widely spread that they are of little taxonomic value. H. antecessor shows juvenile mandibular features which are chronologically and geographically widespread, and similarities with H. pekinensis do not appear significant. The mandible from Mauer, H. heidelbergensis, is generally plesiomorphic, but similar to Neanderthals in a few important features. Neanderthals are a highly peculiar human group from the anatomical, geographical and chronological points of view. They are genetically different from H. sapiens and they seem to emerge in Europe during Middle Pleistocene. Mauer could be one of their earliest representatives.     

Reassessment of type specimens of Cordyceps and its allies described by Dr. Yosio Kobayasi preserved in the mycological herbarium of the National Museum of Nature and Science (TNS). Part 1: the genus Torrubiella

Nineteen holotype specimens of the genus Torrubiella described by Dr. Yosio Kobayasi and Mr. Daisuke Shimizu were relocated and accession numbers (TNS-F number) were given. A new scientific name, Torrubiella plana Hiroki Sato, Ban, Masuya & Hosoya nom. nov. (TNS-F-12061), was proposed for T. minutissima Kobaysi & Shimizu (homonym of T. minutissima Lagarde). The other 18 species follow: T. alboglobosa (TNS-F-12067), T. aurantia (TNS-F-12069), T. corniformis (TNS-F-12064), T. ellipsoidea (TNS-F-12055), T. formosana (TNS-F-12059), T. fusiformis (TNS-F-234548), T. globosostipitata (TNS-F-12057), T. longissima (TNS-F-12071), T. mammillata (TNS-F-12060), T. miyagiana (TNS-F-12062), T. neofusiformis (TNS-F-12058), T. oblonga (TNS-F-12070), T. ooaniensis (TNS-F-12063), T. pallida (TNS-F-12789), T. rosea (TNS-F-12065), T. ryogamimontana (TNS-F-12058), T. ryukyuensis (TNS-F-11932), and T. superficialis (TNS-F-12072).     

Reassessment of type specimens of Cordyceps and its allies, described by Dr. Yosio Kobayasi and preserved in the mycological herbarium of the National Museum of Nature and Science (TNS). Part 3: Cordyceps s. l. on Cicadidae

Twenty taxa of Cordyceps s. l. (belonging to three genera in the latest taxonomic system) from Cicadidae had been described by Kobayasi and Shimizu. Among them, 13 holotype specimens of Cordyceps were rediscovered from preserved specimens partially without ordering, and their registration numbers (TNS-F-number) were given: viz. (1) Elaphocordyceps inegoensis TNS-F-230289, (2) Elaphocordyceps paradoxa TNS-F-230313, (3) Elaphocordyceps toriharamontana TNS-F-230288, (4) Ophiocordyceps heteropoda TNS-F-230294, (5) Ophiocordyceps longissima TNS-F-230285, (6) Ophiocordyceps prolifica f. terminalis TNS-F-230295, (7) Ophiocordyceps pseudolongissima TNS-F-197983, (8) Ophiocordyceps takaoensis TNS-F-3026, (9) Cordyceps kanzashiana TNS-F-198015, (10) Cordyceps kobayasii Koval’ (≡C. sinclairii Kobayasi, not C. sinclairii Berk.) TNS-F-212384, (11) Cordyceps minuta TNS-F-11933, (12) Cordyceps ramosopulvinata TNS-F-197979, and (13) Cordyceps ryogamimontana TNS-F-230292. Two specimens were selected as lectotype: viz. (14) Ophiocordyceps prolifica TNS-F-230300 and (15) Ophiocordyceps yakusimensis TNS-F-230287. A paratype specimen of (16) Cordyceps pleuricapitata TNS-F-197965, and an authentic specimen of (17) Cordyceps imagamiana TNS-F-197966, were also rediscovered.

Notes on Chinese Brachytheciaceae (Ⅰ)

In 1929, V. F. Brotherus published eight species and one form of Chinese Brachytheciaceae based on Handel-Mazzetti's collections from Hunan, Guizhou and Yunnan provinces of China during 1914～1918. The holotypes of all the taxa mentioned above were studied by the present authors. Three names are newly reduced to synonyms: Brachythecium subcurvatulum≡ Brachythecium velutinum ; Rhynchostegium gracilescens≡ Eu-rhynchium savatieri and Rhynchostegium obsoletinerve≡Herzogiella turfacea.     

The “Plastotype Problem” in Ichnological Taxonomy

Abstract

When naming ichnotaxa based on uncollectable trace fossils, the holotype is the actual ichnofossil in the outcrop, though some ichnologists identify the holotype as a replica (cast) held in a museum collection, and refer to it as a “plastotype,” although not all such replicas are made from plaster. Nevertheless, through its Code, the International Commission on Zoological Nomenclature (ICZN) makes it clear that an artificial, human-made replica (plaster cast or otherwise) is not eligible to be the holotype of an ichnotaxon. This directive is potentially destabilizing to much ichnological taxonomy, which is based on holotypes left in the field that have disappeared or will disappear. One possible solution for ichnologists will be to petition the ICZN to recognize that artificial, human-made replicas of ichnofossils can serve as name-bearing types. These may best be called “axiotypes” (from the Greek axios, meaning “of equal value”).
