Spelling Although the ending of the species name may seem feminine and thus incorrect, it is in fact a compound noun formed from "hople" [Greek: thorn] and "akantha" [a Greek nymph]. According to ICZN regulation species names based on compound nouns are not adujusted to the gender of the generic name (Art. 31.2.1.). [details]
