Diagnosis of third instar.

Medium-sized muscidiform larvae with mandibular tooth ventrally grooved, with minute subapical mandibular tooth; with 10-11 oral ridges; accessory plates present; petal-like secondary stomal lobes present, sclerotized stomal guards absent; dorsal spinules present on segments T1-T2; anterior spiracles with 10-13 tubules in a single straight to slightly curved or sinuous row; base of anterior spiracle cylindrical, ca. half as wide as apical width; posterior spiracles with rimae ca. 3 times longer than wide; spiracular processes mostly unbranched to mostly branched with narrow bases; caudal ridge present; anal lobes grooved, posterior portion often larger than anterior portion.

Description of third instar

(differences from Ceratitis rosa description above are noted in bold font). Similar to Ceratitis rosa , except length 3.8-8.9 mm; oral ridges 10-11; accessory plates present, well-developed; parastomal sclerite straight to slightly curved, not hooked apically; CPS length 1.16-1.23 mm, mandible secondary tooth present, mandible tip to notch 0.59-0.63 mm, dorsal cornu length 0.43-0.44, ventral cornu length 0.75-0.80 mm; mandible length a 0.20-0.25 mm, mandible length b 0.25-0.26 mm, mandible length c ca. 0.16 mm, mandible height 0.16-0.17 mm; hypopharyngeal sclerite length 0.16-0.18 mm, dorsal arch height 0.29-0.31 mm. Anterior spiracle with 10-13 tubules, closely spaced in a single slightly sinuous row, apical width 0.19-0.24 mm (n = 7); segments T1-T2 with broken rows of weak, conical spinules on dorsal anterior margin; on T1 the spinulose area encircles the body, while on T2 the ventral spinulose area is separated from that of the dorsum; dorsal spinules absent on T3-A8; posterior spiracle rimae 0.08-0.09 mm long, ca. 0.025 mm wide; spiracular processes mostly unbranched to mostly branched, base of SP-I and SP-IV narrow, numbers of trunks and tips as follows; I (dorsal) (9-12, 13-21), II (3-6, 6-9), III (4-8, 5-11), IV (ventral) (6-11, 11-16); anal lobes grooved, posterior portion often larger than anterior portion.
