(Order Stomatopoda):

Outer branch (ramus) of biramous appendage. Refers to twosegmented branch of antennae, one-segmented, gill-bearing branch of pleopods, and twosegmented branch of uropods, while it is considered to represent inner branch of last three thoracopods. (See also endopod). (Syn. exopodite) [Stachowitsch, 1992].

Outer branch (ramus) of biramous appendage. (elongate and slender, flattened = lamellar = scale-like = plate-like). (Syn. exopodite) [Stachowitsch, 1992].

(Subclass Branchiura):

Setose outer branch (ramus) of thoracic appendage (thoracopod). Exopod of first two thoracopods may bear medially directed flabellum. (See also endopod) [Stachowitsch, 1992].

(Subclass Copepoda):

A dorsal extension of the proximodistal axis of a limb originating on the basis of the protopod and usually segmented. Segments of the exopod bear a dorsal seta and often a ventral seta, but usually there is only one of each kind of seta on a segment [Ferrari and Dahms, in press].
