Resumo(s)
The land snail Oxychilus (Drouetia) atlanticus is endemic to São Miguel (Azores). In this species, the reproductive system, especiailly the glandular organs, changes in size and shape during the reproductive cycle. As maturation-diagnostic organs, the seminal vesicle and the
albumen gland have complementary interpretations. While the former is appropriate to establish the phase of the pre-copulatory and copulatory periods the latter appears a more accurate way to define pre-egg-laying and egg-laying periods. Concerning the effects of photoperiod and temperature on both organs, it seems that while the former triggers the physiological phenomena related to reproduction, inducing the seminal vesicle and the albumen gland to mature, the latter acts mainly as a regulatory factor for these organs, delimiting the distinct phases of reproduction.
