| Description: | In order to introduce a forthcoming paper devoted to the different types of spermatheca within the Coreidae (Hemiptera: Heteroptera), the morphology of the cuticular parts of the coreine spermatheca is here described in detail and illustrated through the example of Coreus marginatus (Linnaeus, 1758), the type species of the type genus of the Coreinae, the subfamily comprising the majority of coreid bugs. Definition and terminology are given for the three morphologically and functionally distinct parts of the organ: (1) the apical seminal receptacle (sperm storage chamber) covered with the efferent ductules of the numerous glandular units forming the spermathecal gland; (2) the intermediate part (muscular pump apparatus) and its own distinct regions, distal, middle and proximal; (3) the spermathecal duct, either simple or with differentiated part along its length. Main variations of these different parts within the Coreinae are mentioned. The presence of two vaginal structures often associated with the coreid spermatheca is also briefly mentioned: the sclerotized ring encircling the parieto-vaginal gland and the fecundation groove. |
