Photographs of the dorsal aspect of the Linnaean collection pinned specimen of this species are available at the Linnean Society of London (2017). The specimen is macropterous and is likely a female as European males are usually micropterous. Specimens of D . bicaudata examined for this study are consistent with previous descriptions and illustrations of this species (Klapálek 1909, 1912 (as Dictyopterygella recta , Dictyopterygella septentrionis – vide Brinck 1949), Hanson 1940 (as Dictyopterygella hudsonica - vide Brinck 1949), Hynes 1940 (as Dictyopterygella recta – vide Brinck 1949), 1941, Brinck 1949, 1954, Koponen 1949 (as Dictyopterygella recta – vide Brinck 1949), Illies 1955, Raušer 1966, Lillehammer 1974, 1988, Stewart & Oswood 2006).
