The produced spermatophores
are then transferred and stored in MVD.
Preston-Mafham 2000): when the first spermatophore
is ready to transfer, the male turns his back while raising his forewings perpendicularly to the body, which exposes the glandular structures located on the metanotum below the base of the forewings.
and spermantangias were cleared with trypsin and then transferred to glycerol (Vecchione, 1991).
We also judged, based on the frequent mating activities observed, that the 26 d period was sufficient for females to pick up necessary spermatophores
were placed in a seminal receptacle below the mouth.
After being discharged from the spermatophore
in the spermatophoric reaction, the sperm mass is encased in a thin covering, with the cement body at one end.
Cloacal glands have been implicated in the production of different components of the male spermatophore
(Sever and Houck, 1985).
In this species, the fecundity and viability of the eggs from females paired with virgin males, and with males who had several matings in 24 hour intervals was not significantly different, even though the spermatophore
transferred in the first copula was significantly larger compared to those later released in additional matings (Knight 2007).

Mate guarding may prevent other males from mating with the female, as these males may dislodge the spermatophore
inserted in a previous mating.
in Aphodiinae (Coleoptera: Scarabaeidae).
One question Zamudio hopes to answer is how female salamanders tell a cousin's spermatophore
from the hundreds of others.
