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.]
(Taxon-specific: 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]
(Taxon-specific: Order Isopoda) Segment of appendage occasionally distinguished proximal to coxa. [Stachowitsch, 1992]
(Taxon-specific: Order Stomatopoda) First segment of thoracic appendage (thoracopod). Also interpreted as being fused to and therefore also termed coxa. [Stachowitsch, 1992]
(Taxon-specific: Subclass Branchiura) In thoracopod, ring-like proximal segment of protopod.
(syn. precoxal ring) [Stachowitsch, 1992]
(Taxon-specific: Subclass Copepoda) The proximal segment of the three-segmented protopod of a postmandibular appendage. [Boxshall and Halsey, 2004]
(Taxon-specific: Subclass Mystacocarida) Protopod. [Stachowitsch, 1992]
