摘要:

Of the thaumastodermatid gastrotrichs that were collected in the years 1989–1991, during a faunistic survey of the Italian coasts, several have been placed in the genusTetranchyroderma. On the basis of their distinctive morphological characters, four that bear pentancres are being described as new species, three with a complete dorsal covering of ancres:T. kontosomum, T. polyprobo‐lostomum, T. tanymesatherum, and one with an incomplete covering:T. anomalopsum.

摘要:

The present work constitutes the first catalogue with commentaries of the earthworms of Madeira. The catalogue comprises a total of 25 species, of which Lumbricidae are the most numerous and representative, while Octochaetidae and Ocnerodrilidae are scarcely represented and have a very limited distribution range. Two species,Eisenia parvaandMicroscolex poulteni, are treated as doubtful, and another five,Dendrobaena lusitana, Dendrobaena hortensis, Pithemera bicincta, Microscolex phosphoreus, andDichogastersp., are cited for the first time for Madeira.Eisenia parvaseems to prefer the shady environment of the degraded laurisilva, while the remaining species live preferentially in the sunny areas devoted to tropical crops.
