oostegites

oostegites
Flattened plates arising from inner proximal margin of coxa of certain pereopods [Holdich and Jones, 1983].
Inner medially directed lamella arising from coxa of pereipod in females participating in formation of mid-ventral marsupium [Moore and McCormick, 1969].
Inwardly directed plates of the leg coxae that form a brood pouch or marsupium [Brusca and Brusca, 2002].
Lamellar lobes of cuticle extending medially from the coxa of an adult female isopod. They may be Seen in two forms: developing oostegites are small fat lobes that do not cross the ventral midline; oostegites of the brooding female are broad, long lamellae that overlap on the ventral midline, forming a marsupium for the developing embryos [Wilson, 1989].
Unique, thinly flattened thoracic coxal endites that form a ventral brood pouch in all peracarids except thermosbaenaceans [Brusca and Brusca, 2002].
(Order Cumacea):
In female, one in a series of flattened plates projecting from basal segments (coxae) of last maxilliped pair and first three pereopod pairs. Overlap to form brood chamber. (See also rudimentary oostegite). (Syn. brood plate) [Stachowitsch, 1992].
(Order Tanaidacea):
In female, one in a series of flattened plates projecting from basal segments (coxae) of second through fifth pereo-pods. Overlap to form marsupium or ovisac [Stachowitsch, 1992].
(Superorder Peracarida):
Inner, medially directed lamella arising from coxa of pereopod in female, part of midventral marsupium [McLaughlin, 1980].
(Order Amphipoda):
In female, one in a series of flattened plates projecting from basal segments (coxae) of second through fifth pereopod pairs. Overlapping or interlocking to form brood chamber (marsupium). (pentagonal, rectangular, subrectangular). (Syn. brood plate) [Stachowitsch, 1992].
(Order Isopoda):
On female, one in a series of flattened plates typically projecting from basal segments (coxae) of second through fifth or sixth pereopods. Overlap to form brood chamber (marsupium). (Syn. brood plate) [Stachowitsch, 1992].
(Order Isopoda):
Thin ventromedial plates, born on coxae of some pereopods in female peracarids forming the marsupium, or broodpouch [Wetzer et al. 1997].
(Order Mysida):
In female, one of two, three, or seven pairs of flattened plates projecting from bases of thoracopods. Overlap to form brood chamber (marsupium). (Syn. brood plate) [Stachowitsch, 1992].
