Ischium

Schematic drawing of a thoracic leg. [Holthuis, 1993]
(Figure only.) [Holthuis, 1993]
Endopod of Mxp 3, lateral; and endopod of Mxp 3, including basal 2 articles, distal articles omitted, central. Based on Munidopsis. [Baba, 2005]
(Figure only.) [Baba, 2005]
Article 3 of pereopod (not always present in tanaids). [Holdich and Jones, 1983]
Fifth article from distal end of leg; usually first large article of maxilliped.
(syn. ischiopodite) [Williams, 1984]
Fifth segment of a pereiopod counted from the distal end. [Ingle, 1983]
See ischiopodite. [Hobbs and Jass, 1988]
See ischiopodite. [Hobbs, Hobbs, and Daniel 1977]
The third segment from the proximal end of a typically 7-segmented appendage.
(pl. Ischia) [Chace and Hobbs, 1969]
The third segment of a thoracic appendage.
See: Pereopod [Wilson, 1989]
Third article of limb (first article of endopod). [Poore, 2004]
Third limb segment distal from body articulating with basis and comprising first segment of endopod.
(syn. ischiopod(ite)) [Moore and McCormick, 1969]
Third podomere from the proximal end of a tyically 7-segmented appendage (Fig. 3C).
(pl. Ischia) [Perez Farfante and Kensley, 1997]
Third segment from the proximal end of a typically 7-segmented appendage.
(pl. ischia) [Butler, T. H.]
Third segment of pereopod or 1st segment of endopod articulating with basis.
(syn. ischiopod) [McLaughlin, 1980]
(Taxon-specific: Order Cumacea) First of five segments (ischium, merus, carpus, propodus, dactylus) of endopod of thoracopod (maxillipeds and pereopods).
(syn. ischiopod, ischiopodite) [Stachowitsch, 1992]
(Taxon-specific: Order Tanaidacea) Third of basically seven segments (coxa, basis, ischium, merus, carpus, propodus, dactylus) of thoracopod. Relatively short; may be fused
with basis.
(syn. ischiopod, ischiopodite) [Stachowitsch, 1992]
(Taxon-specific: Order Decapoda) Third segment of appendage (thoracopod), positioned between basis (last segment of protopod) and merus and thus representing first segment of endopod. May be fused with basis to form ischiobasis or with merus to form ischiomerus.
(syn. ischiopod, ischiopodite) [Stachowitsch, 1992]
(Taxon-specific: Order Amphipoda) Third of basically seven segments (coxa, basis, ischium, merus, carpus, propodus, dactylus) of thoracopod; represents second movable (free) segment.
(syn. ischipopd, ischiopodite) [Stachowitsch, 1992]
Schematic representation of an isopod illustrating morphological terms. [Kensley and Schotte, 1989]
(Taxon-specific: Order Isopoda) Article 3 of pereopod. [Kensley and Schotte, 1989]
(Taxon-specific: Order Isopoda) Third segment of pereopod; located between basis and merus.
(syn. ischiopod, ischiopodite) [Stachowitsch, 1992]
(Taxon-specific: Order Mysida) Second of basically six segments (preischium, ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) of thoracopod.
(syn. ischiopod, ischiopodite) [Stachowitsch, 1992]
(Taxon-specific: Order Stomatopoda) Merus. [Stachowitsch, 1992]
(Taxon-specific: Superorder Syncarida) Second of basically six segments (preischium, ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) or thoracopod.
(syn. ischiopod, ischiopodite) [Stachowitsch, 1992]
(Taxon-specific: Order Thermosbaenacea) First of basically five segments (ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) of thoracopod. Frequently interpreted as being fused to second segment (basis) of protopod in maxilliped, to merus in the other thoracopods (pereopods).
(syn. ischiopod, ischiopodite) [Stachowitsch, 1992]
(Taxon-specific: Order Euphausiacea) Third segment of thoracopod (first segment of endopod); positioned between basis and merus.
(syn. ischiopod, ischiopodite) [Stachowitsch, 1992]
