You say dominula, I say dominulus

Meet the European Paper Wasp, Polistes dominulus.  Or is it Polistes dominula? Most biologists I know refer to this common Holarctic insect as P. dominulus, but I've just learned via that the common spelling is a grammatical misunderstanding of the original latin:

So it's P. dominula.  Damn taxonomists.

Yeah, I just learned about this one, too. Indeed, I should have caught it earlier. But let's not curse the taxonomists, most of whom have a rather poor handle on Latin grammar, and themselves suffer from the interminable linguistic hegemony of the ancient Roman Empire! (Better than phylocode though, eh?)

Most Latin words ending in -ulus, -ulum, -ula are diminutive nouns, maybe even all of them in the classical language. There are a few exceptions though in taxonomic Latin, such as the specific epithet of Paratrechina parvula, a diminutive of a diminutive, if you will. Parvus means small, so parvulus means, roughly, itty-bitty!

I once read a translation of "dominulus" as "builder of a small home in the city," which accurately describes the paper wasps near me.

you can find, at the start of the discussion of the wasp, the following comment:

74. Polistes dominula (Christ, 1791)

Figs B10.1, 3, 4, 44; C74.1â8.

NOMENCLATURAL NOTE. J.M. Carpenter (pers.

comm.) kindly pointed out to us that the correct

gender ending for this species is dominula.

âDominulaâ is the diminutive form of the Latin

noun domina (= mistress) and therefore indeclinable

(the original combination is Vespa dominula
