Species names are not systematic because species are not systematic. The most common definition is reproductive compatibility but that is so complex it's effectively random. Almost identical organisms could consistently fail to produce fully working offspring yet the hybrid of two completely different strains of terran life could theoretically luck into a reproducing cell pattern. For less esotheric examples for the limitations of the species concept look no further than "ring species". Species are not discrete points, they are a continuum that just happens to have a lot of gaps between many of the populated (surviving) areas. Species names are effectively GUIDs, that sometimes encode a bit of proximity assumptions (which may or may not be true). The traditional method of designating those GUIDs (some descriptive plays with a dead language, often namespaced to origin and/or the person who did the first description) surely isn't less mnemonic than other GUID patterns that could have been used instead.
