Macroparalepis Harry 1953    macro-, long, allusion not explained, perhaps referring to longer, more elongate body compared to Paralepis (name proposed by Ege in 1933 but unavailable since he included multiple species without designating which one was the type; many sources credit authorship to Burton 1934 (an entry in the Zoological Record for 1933, published 1934), but Burton merely repeated Ege’s list of species without designating type; Harry was the first to designate a type and hence becomes the author of the genus)
