“Several groups developed active predatory larvae, still showing the spoon-shaped labium.”

“Biplica, in addition, lacks the strongly tubercled and denticulate labium of Eriptycha.”

“One of the most unusual features of odonate larvae is the large, hinged lower lip, or labium.”

“Among the very few cases where they do, are pharyngealization in Nootka, which occurs on the glottal stop only, and labialization in Kabardian.”

“Common secondary articulations are labialisation, palatalisation, velarisation and pharyngealisation.”

“If either of the two was voiceless, the whole cluster was devoiced, and the first obstruent also lost its labialisation, if it was present.”
