protomeriten.

Brit.

/prəʊˈtɒmərʌɪt/, U.S.

/proʊˈtɑməˌraɪt/

Origin: A borrowing from Greek, combined with English elements. Etymons: proto- comb. form, Greek μέρος , -ite suffix¹.

Etymology: < proto- comb. form + ancient Greek μέρος part (see mero- comb. form¹) + -ite suffix¹. Compare deutomerite n. at deuto- comb. form 2, epimerite n.

Zoology.

In certain gregarine protozoans: a distinct anterior section of the main body. Cf. deutomerite n. at deuto- comb. form 2, epimerite n.
