- A specialized genital modification of the three posterior sternites in female penaeidean shrimps. (Pl. thelyca) [Chace and Hobbs, 1969].External pocket on ventral side of thorax in panaeid female serving as seminal receptacle [McLaughlin, 1980].External pocket on ventral side of thorax in penaeid females which functions as seminal receptacle (receptaculum seminalis) [Moore and McCormick, 1969].External seminal receptacle, variously developed, lying on sternum of thorax and formed by outgrowths from last and next to last thoracic somites [Williams, 1984].Female copulatory organs situated in the ventral region of the thorax [Mauchline, 1984].Female genitalia comprising modified posterior two or three sternal plates (Dendrobranchiata) [Poore, 2004].On the ventral surface of the thorax of a female penaeid shrimp; receives the spermatophore from the male during mating [Bliss, 1982].Specialized genital structure of the three posterior sternites in female penaeidean shrimps. (Pl. thelyca) [Butler, T.H.].The female genetalia consisting of modifications of the posterior two, or sometimes three thoracic sternites (XII-XIV) serving for the storage or transfer of the sperm, usually in spermatophores, and often shielding seminal receptacles (Fig. 4A). (Pl. thelca) [Perez Farfante and Kensley, 1997].(Order Decapoda):In female reproductive system of certain shrimp-like (natantian) decapods, pouch-like accessory copulatory structure formed by sternites of last and next to last thoracic somites. Serves as seminal receptacle and may be composed of several lobes or plates [Stachowitsch, 1992].(Order Euphausiacea):In female reproductive system, pouch-like accessory copulatory structure on underside of thorax; associated with female gonopores and formed by sternite and coxal plates of posterior thoracic somite. Receives spermatophore of male [Stachowitsch, 1992].
