|Comment||Abundance: only known from its original description (Meiri et al. 2017).|
|Etymology||The specific epithet punctatonuchalis, is derived from the Latin adjective punctatus, meaning spotted and the Latin noun nuchalis, meaning neck and is in reference to the large, white ocellus on the side of the throat.|
