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).
