Antennal scale (Fig. 2) [Williams, 1984].
Exopod(ite) of antenna in Eumalacostraca; (Similar structure occurs on antennules of Leptostraca.). (Syn. scale) [Moore and McCormick, 1969].
Lateral plate attached to distal margin of second article of antenna, equivalent to exopod (sometimes anntennal scale or acicle when small). (Syn. antennal scale, acicle) [Poore, 2004].
Laterally rigid lamellate exopod of the antenna; the antennal scale (Fig, 1) [Perez Farfante and Kensley, 1997].
Platelike exopod of antenna of shrimps (see "Antennal scale") (Fig. 13) [Hobbs and Jass, 1988].
See: antennal scale [Hobbs, Hobbs, and Daniel 1977].
(Order Decapoda):
In antenna, variously shaped outer branch (exopod) projecting from peduncle. (broad, flat, lanceolate, ovoid, rounded, slender; serrate, setose). (Syn. antennal scale, squama) [Stachowitsch, 1992].
(Order Mysida):
Antennal scale [Stachowitsch, 1992].
(Order Stomatopoda):
Antennal scale [Stachowitsch, 1992].
(Superorder Syncarida):
In antennae of anaspidacean, scale-like outer branch (exopod) arising from second segment of peduncle. May also refer to small exopod in antenna of bathynellacean. (anaspidacean: longer/shorter than first two segments of endopod). (Syn. antennal scale) [Stachowitsch, 1992].
(Order Euphausiacea):
Scale-shaped outer branch (exopod) of each antenna. (Syn. antennal scale, squama) [Stachowitsch, 1992].
