- See: praecoxa [Martin, 2005].Limb segment proximal to coxa, present only in certain subclasses. (Syn. pleuropod) [Moore and McCormick, 1969].Segment of protopod proximal to coxa, rarely present. (Syn. pleuropod) [Butler, T.H.].(Order Tanaidacea):In certain tanaidaceans, apparent segment of pereopod proximal to coxa. According to this interpretation, basal part (protopod) of pereopod consists of three segments (precoxa, coxa, basis) [Stachowitsch, 1992].(Order Isopoda):Segment of appendage occasionally distinguished proximal to coxa [Stachowitsch, 1992].(Order Stomatopoda):First segment of thoracic appendage (thoracopod). Also interpreted as being fused to and therefore also termed coxa [Stachowitsch, 1992].(Subclass Branchiura):In thoracopod, ring-like proximal segment of protopod. (Syn. precoxal ring) [Stachowitsch, 1992].(Subclass Copepoda):The proximal segment of the three-segmented protopod of a postmandibular appendage [Boxshall and Halsey, 2004].(Subclass Mystacocarida):Protopod [Stachowitsch, 1992].
