title: The larva of Aphylla protracta (Hagen, 1859), and a redescription of the larva of A. angustifolia Garrison, 1986 (Odonata: Gomphidae).
abstract: The larva of Aphylla protracta is described and figured. It is characterized by 3rd antennomere subcylindrical, flattened on ventral surface, 4.2 times longer than its widest part. Abdomen with dorsal protuberances well developed on S2-4, reduced on S5, vestigial or absent on S6-9; lateral spines lacking entirely, tergites 5-8 with minute reddish setae, tergite 9 with abundant, small, reddish setae on most of its surface and the whole posterior margin; S10 cylindrical, very long, five times longer than its base, much longer than S6+7+8+9. Also, a redescription and figures of A. angustifolia are provided, and a comparison of both species is made. Mainly differences between both species were found in abdominal dorsal protuberances and the presence/absence of small setae on abdominal tergites.
