(Order Cumacea):

Second of five segments (ischium, merus, carpus, propodus, dactylus) of endopod of thoracopod (maxillipeds and pereopods). (Syn. meropod, meropodite) [Stachowitsch, 1992].

(Order Tanaidacea):

Fourth of basically seven segments (coxa, basis, ischium, merus, carpus, propodus, dactylus) of thoracopod. (Syn. meropod, meropodite) [Stachowitsch, 1992].

(Order Decapoda):

Fourth segment of appendage (thoracopod); positioned between ischium and carpus. May be fused to ischium to form ischiomerus. (Syn. meropod, meropodite) [Stachowitsch, 1992].

(Order Amphipoda):

Fourth of basically seven segments (coxa, basis, ischium, merus, carpus propodus, dactylus) of thoracopod; represents third movable (free) segment. (Syn. meropod, meropodite) [Stachowitsch, 1992].

^{Schematic representation of an isopod illustrating morphological terms. [Kensley and Schotte, 1989]}

Fourth segment of pereopod; located between ischium and carpus. (Syn. meropod, meropodite) [Stachowitsch, 1992].

(Order Mysida):

Third of basically six segments (preischium, ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) of thoracopod. (Syn. meropod, meropodite) [Stachowitsch, 1992].

(Order Stomatopoda):

Fourth segment of thoracic appendage (thoracopod). Considered to represent fused ischium and merus (ischiomerus), yet also interpreted as being separate from and following ischium [Stachowitsch, 1992].

(Order Thermosbaenacea):

Second of basically five segments (ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) of thoracopod. Frequently interpreted as being fused to ischium. (Syn. meropod, meropodite) [Stachowitsch, 1992].

(Order Euphausiacea):

Fourth segment of thoracopod (second segment of fivesegmented endopod); positioned between ischium and carpus. (Syn. meropod, meropodite) [Stachowitsch, 1992].
