查看更多>>摘要:The Columbariinae have been represented in the fauna of New Zealand from the Paleocene until the Recent, providing the longest known continuous record for the subfamily. Seven living species, representing the genera Columbarium, Coluzea, and Fulgurofusus, are recognized, and include two species, Fulgurofusus maxwelli and Fulgurofusus marshalli that are described as new. The New Zealand columbariine fauna is unusually diverse at the generic level, and includes the largest members of the subfamily, aswell as the only primarily sublittoral species. The morphology, anatomy, and distribution of the living species are discussed, as are their relationships to living and fossil congeners.
查看更多>>摘要:Arthroleptis krokosua Ernst, Agyei & Rodel, 2008 is a recently described, morphologically distinct squeaker species. It has no apparent affiliations to any other West African member of the genus (Ernst et al. 2008), but instead is most closely relatedto some Central African Arthroleptis (Blackburn et al. 2010). It differs from all known West African Arthroleptis by its large size (> 40 mm snout-vent-length), coloration and other morphological characters, such as a very broad head. Until now the species is only known from the type locality, the Krokosua Hills Forest Reserve and only from the holotype (Ernst et al. 2008). Other large Arthroleptis (larger than 35 mm SVL) are known from Central and East Africa (Blackburn et al. 2009). As A. krokosua might be locally endemic, i.e. amphibian assessments in other Ghanaian and eastern Ivorian forests failed to detect this species (Hillers et al. 2009 and literature cited therein); we herein aim to add more data on the variability, distribution and ecology of A. krokosua.

Our preferred phylogenetic tree inferred from Maximum Parsimony and Bayesian methods reveal six major clades within the genus leading to recognition of S. natator, S. nubilus, S. guttatus, S. tuberilinguis, S. parvus, and S. latopalmatus. For species where multiple populations were assessed, we found high genetic variation that may eventually support the recognition of new species.
查看更多>>摘要:The Taiwan population of the Polypedates leucomystax complex has been assigned to P. megacephalus, which was originally described from Hong Kong. The Taiwan and Hong Kong populations, however, are markedly differentiated in DNA sequences, and advertisement call and morphological characteristics. The Taiwan population is therefore regarded as a distinct species, for which the name P. braueri (Vogt 1911) is available. Since the holotype of P. braueri was not designated, a lectotype is chosen among thenine syntypes examined.

Several lines of evidence show that both taxa refer to the same biological species. Various morphologic characters enumerated by the two research teams for A. polopi and A. viridescens are coincident. The brownish coloration of the dorsal pelage, the chin with a small but distinguishable white patch, the tail of approximately 70% of head and body length, and the broad rostrum are among the diagnostic characters cited for both forms. Other additional characters mentioned in the diagnosis of only one of the nominal forms are also enumerated in the general description of the other.
查看更多>>摘要:The Diplopoda is a megadiverse group, comprising > 12,000 nominal species with an estimate of total global diversity as high as 80,000 (Adis & Harvey 2000; Hoffman 1980; Sierwald & Bond 2007). An electronic, searchable database of the Diplopoda is currently being compiled at the Field Museum of Natural History in Chicago, IL. This catalog, and others like it, provides the basis and quality assurance for future taxonomic works and larger initiatives like the Encyclopedia of Life (EOL). The catalog will contain the most up-to-date and researched account of millipede diversity and literature records ever compiled and will be made accessible online.
