A spine was observed in the hind wings of male coffee berry borers, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), although it was not present in all males. Females do not exhibit the spine. The function of the spine remains unknown although one possibility is that it might have had a stridulatory role in acoustic communication.



La presencia de una espina fue observada en las alas posteriores de machos de la broca del café, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), pero no todos los machos la tienen. Las hembras no poseen la espina en el ala. La función de la espina es desconocida, pero es posible que haya tenido un rol en estridulación y comunicación acústica en esta especie.
