Coccotylus truncatus (Pallas) M.J.Wynne & J.N.Heine 1992: 75

Published in: Wynne, M.J. & Heine, J.N. (1992). Collections of marine red algae from St. Matthew and St. Lawrence Islands, the Bering Sea. Nova Hedwigia 55: 55-97.

Type species
The type species (holotype) of the genus Coccotylus is Coccotylus brodiei (Turner) Kützing.

Status of name
This name is of an entity that is currently accepted taxonomically.

Fucus truncatus Pallas

Type information
Type locality: "Eismeer", Eastern Siberia (Index Nominum Algarum). Lectotype: LE (Le Gall & Saunders 2010: 382). Notes: Dixon & Irvine (1977: 227) cite "lectotype: LE" Arctic Seas but do not indicate who it was designated the lectotype. Le Gall & Saunders (2010: 382) designate as lectotype, a specimen labeled "truncatus" in what must be Pallas's hand (shown in a copy of photographs of Pallas's collection). Le Gall & Saunders (2010: 382) write "Although Newroth (1970, p. 30; see also Newroth and Taylor 1971) did not view the type collection at the time he wrote his PhD dissertation, he relays correspondence with Zinova in which a specimen with Pallas’s handwriting is discussed and presumably provides the basis for figure 1 in her own work (Zinova 1970, the figure caption in Russian indicating essentially ‘‘Typical form’’) in which the new combination Phyllophora truncata (Pall.) Zinova is presented. Subsequently, Newroth received two photographs of Pallas’s collection and kindly provided us with a copy, which shows a specimen labeled ‘‘truncatus’’ in what must be Pallas’s hand that we designate as the lectotype of C. truncatus."

Origin of species name
Adjective (Latin), truncate, i.e., ending very abruptly as if cut straing across (Stearn 1985).
