|Comment||PETERS (1869) ascribes “C. Borckiana” to Merrem 1809 who may have described the species in the “Ann. d. Wetterauischen Gesellschaft 1809”. See also Myers et al. 2011. Centropyx copii Garman, 1887 was described by Cope (1861) as an example of C. intermedius Schlegel, fide G.R. Zug, January 1969 (fide USNM catalog).|
Distribution: Has been erroneously reported from Trinidad (BOOS & QUESNEL 1971).
|Etymology||Named after Johann Graf von Borcke (1781-1862) who joined the Prussian Army (1797), served temporarily in the Westphalian Army in Spain and in Russia, before re-joining the Prussian army. He fought at both Ligny and Waterloo. He retired from the army (1832). Merrem reported that Major von Borcke had presented a number of specimens to the Berlin Museum and that they had come originally from the sale of Albertus Seba’s collection. Peters, who re-described the animal (1869), remarked that unfortunately the original specimen of the Borcke collection got lost.|
