Abstract

SummaryThe first data on the developmental life cycle of Acinipe segurensis (Bolívar, 1908) are provided as well as a morphological description of the nymphal stages. Data provided refer to the number of nymphal stages in the two sexes and their duration. The species hibernate in the egg stage. Males undergo four nymphal stages before reaching the adult stage, while females undergo five, the extra stage being the third one. Morphological features studied concerning the number of antennal segments, the morphology of the wing rudiments on lateral lobes of the meso- and metanotum and the morphology of the external genitalia both in male and female, allowed us to briefly describe and illustrate the different nymphal stages. The life cycle is different from other Pamphagini species as concerns the hibernation period and the rate of nymphal growth. A discussion on the possible causes of such divergences is given.
