Resumen Parachondria neglectus es un molusco terrestre de la familia Annulariidae, endémico de Cuba y microlocalizado en la provincia de Granma. En la presente investigación se caracterizaron la dinámica temporal del subnicho etario y algunos aspectos de la biología reproductiva de una población de P. neglectus localizada en Manzanillo, GranmaCuba. Se realizaron 30 expediciones entre diciembre 2013 y febrero 2015. Las comparaciones del largo (t = 8.05, P = 0.007) y diámetro mayor (t = 6.24, P = 0.0001) de las conchas de los juveniles truncados y los juveniles completos mostraron diferencias estadísticas significativas, indicando que ambos grupos representan dos clases de edades diferentes. La comparación del diámetro mayor de las conchas de los adultos truncados y los adultos completos (t = 1.50, P = 0.16) demostró que conforman un misma clase de edad en la población. La existencia de diferencias estadísticas significativas entre el largo (t = 19.45, P = 0.0003) y el diámetro mayor (t = 13.19, P = 0.006) de las conchas de las hembras y los machos reafirmaron el dimorfismo sexual en la especie, resultando las hembras de mayores dimensiones respecto a los machos. La mancha circular blancuzca en las conchas es una característica morfológica externa válida para diferenciar a las hembras adultas y ya apareadas en ocasiones anteriores, del resto de los miembros de la población. El período reproductivo comprendió de julio a diciembre 2014. Las cópulas se observaron de julio a octubre 2014 y estuvieron asociadas a condiciones de precipitaciones abundantes y temperaturas altas del verano. El período de reclutamiento ocurrió de septiembre a diciembre 2014. Abstract Parachondria neglectus is a land snail of the Annulariidae family, endemic to Cuba and microlocalized in Granma province. In the present research, the temporal dynamics of age-related subniche and some aspects of the reproductive biology of a P. neglectus population, located in ManzanilloGranma-Cuba, were characterized. Thirty expeditions were performed from December 2013 to February 2015. The comparisons between the length (t = 8.05, P = 0.007) and biggest diameter (t = 6.24, P = 0.0001) of the shells of truncated juveniles and the shells of full juveniles showed significant statistical differences, indicating that both groups represent two kinds of different ages. The comparison between the biggest diameter of the shells of truncated adults and the shells of full adults (t = 1.50, P = 0.16) showed that both groups represent the same kind of age in the population. The existence of significant statistical differences between the length (t = 19.45, P = 0.0003) and the biggest diameter (t = 13.19, P = 0.006) of the females’ shells and the males’ shells verify the sexual dimorphism in the species, proving to be the females of bigger dimensions in relation to the males. The whitish circular spot in the shells is a valid external morphological characteristic to differentiate the adult females already mated in previous occasions from the rest of the members of the population. The reproductive period was from July to December 2014. Copulations were observed from July to October 2014 and they were associated to conditions of abundant precipitations and high temperatures of summer. The recruitment period took place from September to December 2014.
