Uniramian.

Brit.

/ˌjuːnɪˈreɪmɪə/, U.S.

/ˌjunəˈreɪmiə/

Origin: A borrowing from Latin. Etymon: Latin Uniramia.

Etymology: < scientific Latin Uniramia (see quot. 1972) < classical Latin ūni- uni- comb. form + rāmus branch (see ramus n.) + -ia -ia suffix². Compare earlier uniramous adj. at uni- comb. form 1a.

Zoology.

With plural agreement: a subphylum or phylum of arthropods having unbranched (uniramous) limbs, comprising the insects and myriapods, and formerly (in Manton's original scheme) also the onychophorans. Also: animals of this subphylum or phylum (collectively or individually).Arthropod taxonomy is currently under review and Uniramia is being replaced by other taxa. In schemes that do not include crustaceans in the Mandibulata, the latter is effectively synonymous with Uniramia.
