Carpomya pardalina (Bigot)

Carpomyia pardalina Bigot, Myiopardalis pardalina (Bigot), Carpomyia caucasica Zaitzev

Baluchistan melon fly, Russian melon fly. Body length 8–10mm; elongate-cylindrical (?). Integument unsclerotized, entirely whitish to yellowish. Caudal ridge absent. Mature larvae unable to jump.

Head. Head of normal shape; cephalic lobes slightly developed. Antenna 2-segmented. Stomal organ: primary lobe rounded, protuberant; number of peg sensilla one (small); peg sensilla unbranched; other peg-sensilla-like structures absent. Stomal region: secondary lobes absent; sclerotized stomal guards present; number of sclerotized stomal guards 3 (large). Oral ridges present; number of oral ridges 4–7; margins dentate (sharply pointed teeth;sparse). Accessory plates present; number of accessory plates 1 (~~); margins serrated. Elongate, finger-like lobes arising above mandibles absent. Median oral lobe absent or not protruding. Labium broad.

Cephalopharyngeal skeleton. Mandibles: subapical teeth absent; base stout, nearly perpendicular to a line from ventral part of base to apex of mandible. Parastomal bars elongate, free from hypopharyngeal sclerite. Dental sclerites apparently absent, not visible in lateral view.

Spinules and creeping welts. Dorsal spinules on segments T1-A6.

Caudal segment (a8) and anal lobes. Sensilla on caudal segment 10 pairs, with at least 7 pairs visible under dissecting microscope. Intermediate caudal sensilla I1a&b obvious, on a single papilla or tubercle, not bifid apically (?), or obvious, on a single papilla or tubercle, bifid apically (?). Intermediate caudal sensillum I2 obvious (?). Intermediate caudal sensilla I1a&b and I2 on a single tubercle. Ventral caudal sensilla ?. Anal lobes plainly visible, but not strongly protuberant (small).

Anterior spiracles. Anterior spiracle elevated, margin convex to straight, or elevated, margin concave medially, appearing bilobed (?). Anterior spiracular tubules 26–28 (9–10~Janjua 1954); in a single irregular row (long).

Posterior spiracles. Posterior spiracular area not distinctly set off from caudal segment. Posterior spiracles: slits 3–4x longer than wide. Dorsal spiracular processes with a few trunks radiating from a short or semicircular base (medium processes). Number of dorsal spiracular processes 7–9 (?). Number of ventral spiracular processes 7–9 (?). Number of lateral spiracular processes 4–8 (?; SPII: 4–5; SPIII: 6–8). Dorsal and ventral spiracular processes: average number of tips 7–10. Dorsal and ventral spiracular processes: ratio of number of tips to number of trunks 1–1.4. Area between posterior spiracles with a cellular or rugose appearance.

Host plants. Cucurbitaceae (Citrullus lanatus, Cucumis sativus, C. melo, Ecballium elaterium, as “Citrullus vulgaris, Cucumis spp., Cucurbita spp., Ecballium elaterium, Melo sp.” ~Kandybina 1977).

Part of plant attacked: fruit.

Biogeographic region. Palearctic.

Specimens examined. Based on description by Kandybina (1965; 1977).

Sources of data and SEM numbers: 349.
