Labia minor

Labia minor is a good example of the unexpected surprises and humour which exist in the world of biological nomenclature. In this case the name applies not just to the “two longitudinal cutaneous folds on the human vulva” but is also the specific name for the Lesser Earwig.

Fortunately such eclecticisms are being collected by Mark Isaak at Curiosities of Biological Nomenclature. As Isaak says:

Scientific names of organisms are not usually known for their entertainment value. They are indispensable for clarity in communication, but most people skip over them with barely a glance. Here I collect those names that are worth a second look.

Some names are interesting for what they are named after (for example, Arthurdactylus conandoylensis, Godzillius), some are puns (La cucaracha, Phthiria relativitae), and some show other kinds of wordplay (such as the palindromic Orizabus subaziro). Some have achieved notability through accident of history, and many show the sense of humor of taxonomists.

If you’re interested in either biology or words it’s well worth a look. But prepare to be amazed for amongst the collected examples you’ll also find:

  • Unifolium bifolium (European May Lily); basically “single leaved plant with two leaves”
  • Abra cadabra (a clam)
  • Ba humbugi (a snail); from the Fijian island of Mba
  • Panama canalia (braconid fly)
  • Mozartella beethoveni (encyrtid wasp)
  • and of course Labia minor (Lesser Earwig); “small lips”; don’t ask why this would be appropriate for an earwig!

Isaak has even included an essential guide to the basic rules of biological binomial nomenclature. And a section on the (increasingly weird) names being given to genes – the well known gene sonic hedgehog isn’t the half of it!

My favourite? Well one of the best named is surely Boselaphus tragocamelus, an antelope (below) whose name translates from the Latin as “ox-deer goat-camel”. Clearly named, as well as designed, by a committee!
