We studied the macroscopic and histological morphology of the reproductive male tract for Macroperipatus aff. geayi and its development from fetuses through neonates to individuals of different body sizes. We also determined if there were similar or shared characteristics with other onychophorans belonging to the Peripatidae family. Additionally
the body size at which males reach the sexual maturity was elucidated. The general anatomy was similar to the one reported for other species of the Peripatidae family. Neonates and specimens with different body sizes were mature producing spermatozoa at the seminal vesicle
and reproductively active because they produce spermatophores within the vas deferens. The pigmented fetuses
near to birth and found in the descendent oviduct of females
were recognized as sexually mature but not reproductively active
since although they produce spermatozoa they did not have spermatophores in their vas deferens. The partially pigmented fetuses
also found in the descendent oviduct but in a more anterior position and in a previous developmental stage
did not have spermatozoa
however
spermiogenesis is already occurring. Consequently
the individuals of this population initiate the spermiogenesis process during their fetal development and produce spermatozoa as advanced fetuses. Males can be reproductively active from neonates
because at this stage they are capable of producing spermatophores for transferring into the female gonopore

La anatomía general es similar a la reportada en otras especies de la familia Peripatidae. Los neonatos y toda la serie de tamaños encontrada fueron maduros, produciendo activamente espermatozoides a nivel de la vesícula seminal y reproductivamente activos ya que producen espermatóforos en el conducto deferente. Los fetos pigmentados próximos al nacimiento y encontrados en el oviducto descendente de las madres fueron considerados sexualmente maduros, pero no reproductivamente activos, ya que no se encontraron espermatóforos en el lumen del conducto deferente. Los fetos parcialmente pigmentados, que también se encuentran en el oviducto descendente de sus madres pero en una posición más anterior y en un estado previo de desarrollo, no presentan aún espermatozoides, pero la espermiogénesis ya está ocurriendo. Así, los individuos de esta población inician el proceso de espermiogénesis durante su desarrollo fetal y producen espermatozoides como fetos avanzados. Sólo serían reproductivamente activos cuando neonatos, pues sólo en este estado son capaces de producir espermatóforos para transferir al gonoporo de la hembra
