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.
