remarks (from publication):
Weyenbergh in 1877 described Synbranchus döringii from lakes near Santa Fé, Argentina. Synbranchus döringii is considered as a synonym of Synbranchus marmoratus, a widespread species occurring throughout Central and South America (Kullander 2003). Synbranchus Döringii, as spelled in the original description, is frequently listed sub S. doringii by recent authors (e.g. Eschmeyer 1998; Kullander 2003). Eschmeyer emended Döringii to doringii and additionally said “Species name originally spelled as Döringii; if based on a German name the correct spelling would be doeringii”…
… The family name Döring originates from the low German dialect spoken in northwestern Germany, including the Hannover area, and means ‘thuringian’ or ‘one from Thuringia’ (Kohlheim 2005), today a german province.
A family name with its origin in the medieval dialect of a German region with a meaning referring to another German region is to be considered a German name.
The specific name Synbranchus döringii is based on the stem Döring, a family name of German origin, latinized to Döringius. In accordance with articles 19.2., and 33.2.2. of the International Code of Zoological Nomenclature (International Commission for Zoological Nomenclature 1999) it is hereby emended to Synbranchus doeringii Weyenbergh, 1877.
