1872 A. S. Packard Insects 29 The roof of the mouth is formed by the labrum and the epipharynx,..a small fleshy tubercle concealed beneath the labrum.

1897 T. J. Parker & W. A. Haswell Text-bk. Zool. I. xi. 592 A projection of the roof of the mouth cavity (epipharynx) is present in some Insects.

1909 Cambr. Nat. Hist. IV. xviii. 459 In those free living Mites which have undergone no great modification of the mouth parts two other portions can be distinguished, the upper lip or ‘epipharynx’, and the ‘lingua’.

1957 O. W. Richards & R. G. Davies Imms's Gen. Textbk. Entomol. (ed. 9) iii. 589 (Diptera) The labrum..is dorsally well sclerotized but ventrally more membranous, this surface sometimes being termed the epipharynx.

1957 O. W. Richards & R. G. Davies Imms's Gen. Textbk. Entomol. (ed. 9) iii. 669 [Siphonaptera] The epipharynx is a long slender organ which is ventrally grooved.

1957 O. W. Richards & R. G. Davies Imms's Gen. Textbk. Entomol. (ed. 9) iii. 676 (Hymenoptera) An epipharynx is well developed and trilobed in the higher forms, the median lobe being pointed and projecting.
