Anastrepha interrupta

Common name  

Schoepfia fruit fly

Description

Typical of Anastrepha larvae with the following specific characteristics for the third instar:

Body. Length 5.8–9.3mm.

Head. Number of oral ridges usually 15–20 (occ.13–14).

Cephalopharyngeal skeleton.

Spinules and creeping welts. Dorsal spinules on segments T1-T3, or T1-A1.

Anterior spiracles. Anterior spiracular tubules 10–13 in a single row.

Caudal segment (A8) and anal lobes.  Anal lobes plainly visible, but not protuberant; simple, or grooved, or bifid.

Posterior spiracles. Length of dorsal and ventral rimae 67–89 µm; slits 2.6–3.9x longer than wide. Dorsal spiracular processes (SPI) with 4–8 trunks and 5–11 tips. Ventral spiracular processes (SPIV) with 4–7 trunks and 4–10 tips. Basal width of SPI spiracular processes 7–12 µm. Basal width of SPIV spiracular processes 5–10 µm. Dorsal and ventral spiracular processes: ratio of number of tips to number of trunks 1–2. Lateral spiracular processes 3–6 trunks and 3–8 tips.
