Etymology Not stated by the authors. The specific epithet aulogastrella is composed by the name of the species Ammotrypane aulogaster Rathke, 1843, type of the genus Ammotrypane Rathke, 1843 (junior synonym of Ophelina Örsted, 1843), and the Latin suffix -ella, normally added to a noun to form a diminuitive of that noun, in the sense of 'little one resembling', and refers presumably to the reduced size and resemblance of the new species with A. aulogaster: "Length of body [of A. aulogastrella] ranges from 15.5 to 22.5 mm, width 1 to 2 mm, and setigers number 28 to 33 [vs. 25-60 mm long, 2-5 mm wide, 50-60 setigers, in A. aulogaster; see: McIntosh, 1915: 15; Fauvel, 1927: 133; Hartmann-Schröder, 1996: 427] [...] A. aulogastrella differs from A. aulogaster in that it lacks branchiae in its posterior half" (Hartman & Fauchald, 1971: 130-131).
