It is scarce the information about the reproductive biology of the highland tropical snakes and even more if they are fossorial. This work describes the morphology of the female reproductive tract of a population of Atractus sp
and its reproductive activity during some months. Atractus sp has a paired and asymmetric tract. The vitellogenic females exhibit a maximum of 12 ovarian follicles of different sizes; these follicles are grouped in series of two follicles of similar size and growth state per ovary. Thus
the clutch size varies from two to four eggs. Histologically
the oviduct is divided in infundibulum
uterus
transition uterus-vagina
and vagina. The luminal epithelium of the entire oviduct is columnar to cuboidal with ciliated and nonciliated cells in constant secretory activity. Abundant shell glands are found in the uterus; they have increased secretory activity in vitellogenic females. Sperm storage was found in vitellogenic females in the posterior infundibulum at the bottom of sacs formed by invaginations of the luminal epithelium. Sperm was also found in adult females (vitellogenic and no vitellogenic) in the transition uterus-vagina and in the vagina
located sparse in the lumen and organized in the basal areas of epithelial folds in which the luminal epithelium is mainly ciliated. The minimum size of sexual maturity was 216 mm and during the sampling time reproductive females were ever found

Atractus sp presenta un tracto pareado asimétrico. Los ovarios en hembras vitelogénicas muestran un número máximo de 12 folículos de diversos tamaños, estos folículos se agrupan entre sí en series de tamaños y estados de crecimiento similares. En hembras en vitelogénesis avanzada dichas series no exceden los dos folículos por ovario; así el tamaño de la postura varía entre dos a cuatro huevos. El oviducto se divide en infundíbulo, útero, zona de transición útero-vagina y vagina. El epitelio luminal de todo el oviducto muestra células ciliadas y no ciliadas con constante actividad secretora, y forma abundantes glándulas de la cáscara en la región uterina; la actividad secretora se incrementa en hembras en vitelogénesis. El almacenamiento de esperma ocurre en la zona posterior del infundíbulo, en la transición útero-vagina y en la vagina. El almacenamiento de esperma en el infundíbulo posterior ocurre en el fondo de bolsas formadas por invaginaciones del epitelio luminal y fue observado en hembras vitelogénicas. En la zona de transición útero- vagina y en la vagina se encuentran los espermatozoides en las zonas basales de los pliegues del epitelio, el cual es mayoritariamente ciliado; se observaron en hembras no vitelogénicas adultas y en vitelogénesis. El tamaño mínimo de madurez sexual fue de 216mm y durante el tiempo muestreado se encontraron hembras reproductivas permanentemente, sugiriendo una actividad reproductiva continua
