The larva of Libellula foliata (Kirby, 1889) (Odonata: Libellulidae)

摘要

The larva of Libellula foliata (Kirby) is described based upon mature larvae from the Biosphere Reserve of “El Triunfo” in the state of Chiapas. It belongs to the small group of species without dorsal protuberances, L. composita (Hagen), L. comanche Calvert and L. saturata Uhler. The following combination of characters permits the separation of L. foliata larva from the other aforementioned larvae: tergites 6–10 uniformly colored, no lateral spines on segments 8–9, 5–6 palpal setae and 3 long premental setae. After this finding, only the larvae of Libellula gaigei Gloyd and L. nodisticta Hagen remain undiscovered for the Mexican species of Libellula.
