Erséus, C. (Department of Zoology, University of Göteborg, S‐400 33 Göteborg, Sweden) and Lasserre, P. Taxonomic status and geographic variation of the marine enchytracid genus Grania Southern (Oligochaeta) . Zool. Scr. 5 (3–4): 121–132, 1976.—New material from Europe, Bermuda and the eastern coast of North America allow more realistic determination of the generic characteristics of the marine enchytraeid genus Grania . This re‐evaluation of Grania necessitates the consideration of Hemigrania as a junior synonym, because of the now established absence of peptonephridia in Grania . Full enumeration of known localities shows the genus Grania to have a broad, disjunct distribution, low species number, and morphological conservatism. G. postclitellochaeta (Knöllner) and G. macrochaeta (Pierantoni) are considered as polytypic species, containing respectively two (including G. postclitellochaeta longiducta subsp.n.) and three (including G. macrochaeta bermudensis subsp.n.) subspecies. G. maricola Southern, G. roscoffensis Lasserre, G. vario‐chaeia sp.n. and G. monospermatheca sp.n. are considered as monotypic species.
