Description
Typical of Anastrepha larvae with the following specific characteristics for the third instar:
Body. Body length 5.8–8.3mm.
Head. Number of oral ridges 20–30. Median oral lobe absent or not protruding (?).
Spinules and creeping welts. Dorsal spinules on segments T1-A5.
Anterior spiracles. Anterior spiracular tubules 17–22.
Caudal segment (a8) and anal lobes. Anal lobes plainly visible, but not protuberant; simple.
Posterior spiracles. Posterior spiracles: slits 2.4–3.6x longer than wide. Dorsal spiracular processes with numerous trunks arising from a short or semicircular base, or with fewer trunks radiating from a short or semicircular base (short processes). Number of dorsal spiracular processes ~ 10. Number of ventral spiracular processes ~ 9. Number of lateral spiracular processes ~ 7–8. Dorsal and ventral spiracular processes: average number of tips 8–14. Dorsal and ventral spiracular processes: ratio of number of tips to number of trunks 2.7–3.3.
