Definitions

Lateral expansion of coxa broadly joined to lateral mergin of tergite. [McLaughlin, 1980]
Lateral expansion of pereiopod coxa joined broadly to lateral margins of tergites. [Moore and McCormick, 1969]
Pereopodal coxae that are expanded as lateral side plates in some of the more derived groups of isopods and in some amphipods. [Brusca and Brusca, 2002]
(Taxon-specific: Order Amphipoda) Modification of proximal segment (coxa) of appendage (e.g., pereopod) into immovable, plate-like structure. Serves protect gills and accentuates laterally compressed shape of body, (contiguous, discontiguous; bilobed, rectangular, rounded, spiniform; margin: setose, serrate, smooth; ornamentation: setose, with ridges, spines, tubercles). [Stachowitsch, 1992]
(Taxon-specific: Order Isopoda) Coxae of the pereopods laterally expanded into flattened lamellar structures extending freely (as "plates") to overhang the coxa-basis hinge of the leg. [Wetzer et al. 1997]
(Taxon-specific: Order Isopoda) Lateral extension of proximal segment (coxa) of pereopod; may be fused to body wall.
(syn. epimere) [Stachowitsch, 1992]
