3 as spermathecal diameter, spermathecal common duct shortest than spermatheca
, and individual spermathecal duct at least 4.
Queens instrumentally or naturally inseminated showed a complete filling of the spermatheca
, leading to a positive correlation between the queen weight, the brood area of the colony and the number of sperm in the spermatheca
(Akyol et al.
1758) based on the anatomical changes of the spermatheca
(Decapoda, Brachyura, Portunidae).
The female needs the sperm to stay healthy whilst they are in storage in the spermatheca
, so that they are viable each time she uses them to reproduce.
The male embolus was inserted completely into the female vulva with the tip of the embolus inserted into the orifice of the spermatheca
is nothing more than a bud of gland developing from the wall of the uterus externus.
An expanded region at the base of the spermatheca
houses a valve-like structure with a narrow pore; under the light microscope the valve is translucent and membranous (Fig.
The subfamily Proscopiinae contains two tribes, each with genera clearly related by their external and internal morphology, their habits and their distribution: tribe Proscopiini--Amazonic, arboreal, mostly of large size, with marked sexual dimorphism, male genitalia with complex sclerotized structures in the endophallus, and female genitalia with a single spermatheca
more or less complex.

Soon after her birth, a queen mates with as many as 18 drones from other hives and the spermatheca
becomes filled with a lifetime supply of sperm.
During copulation the flagellum is threaded up the female's long and convoluted spermathecal duct and into the ampulla and occasionally also into the spermatheca
