Marsupium

A ventral pereonal enclosure on females for developing embryos. It is composed of oostegites projecting medially from the coxae of the anterior pereopods (Pereopoda I-VI in the munnopsids). [Wilson, 1989]
Brood pouch. [Moore and McCormick, 1969]
Brood pouch. [McLaughlin, 1980]
Chamber on ventral surface of female formed by overlapping oostegites in which the eggs, embryos and mancas are brooded. [Holdich and Jones, 1983]
Ventral brood pouch formed from inwardly directed plates of the leg coxae (called oostegites) in most peracarids. [Brusca and Brusca, 2002]
(Taxon-specific: Order Cumacea) Brood chamber. [Stachowitsch, 1992]
(Taxon-specific: Order Tanaidacea) In female, chamber formed on ventral surface of pereon by oostegites.
See: Ovisac [Stachowitsch, 1992]
(Taxon-specific: Order Amphipoda) Brood pouch. [Stachowitsch, 1992]
(Taxon-specific: Order Isopoda) Brood pouch. [Stachowitsch, 1992]
(Taxon-specific: Order Isopoda) Structure in which eggs and embryos are retained and brooded by female the broodpouch. Isopod marsupia are typically formed by overlapping medial plates (oostegites) arising from certain pereonal coxae in females; in a few groups the oostegites have been reduced or lost in lieu of internal brooding. [Wetzer et al. 1997]
(Taxon-specific: Order Isopoda) Structure in which eggs are retained by female, the broodpouch. [Kensley and Schotte, 1989]
(Taxon-specific: Order Mysida) In female, chamber formed on ventral surface of thorax on two to seven pairs of oostegites. Serves to brood eggs and embryos.

(Taxon-specific: Order Thermosbaenacea) Brood pouch. [Stachowitsch, 1992]
