Ceratitis pedestris (Bezzi)

Pardalaspis pedestris Bezzi

Strychnos fruit fly. Body length 6–8mm (range estimated, LEC coded as 7); slender, elongate, tapering anteriorly, or stout, elongate, tapering anteriorly (?). Integument unsclerotized, entirely whitish to yellowish. Caudal ridge present. Mature larvae able to jump (?).

Head. Head of normal shape; cephalic lobes moderately developed. Antenna 2-segmented. Stomal organ: primary lobe small, round; number of peg sensilla three (small, peg-like); peg sensilla unbranched; other peg-sensilla-like structures absent. Stomal region: secondary lobes present, short, leaf-like (5 preoral lobes); margins of secondary lobes all entire; sclerotized stomal guards absent (?). Oral ridges present; number of oral ridges 6–8 (range estimated, LEC coded 7); margins serrate (short, bluntly rounded teeth). Accessory plates absent. Elongate, finger-like lobes arising above mandibles absent. Median oral lobe absent or not protruding. Labium broad (?).

Cephalopharyngeal skeleton. Mandibles: subapical teeth absent. Parastomal bars elongate, free from hypopharyngeal sclerite (?). Dental sclerites present, posterior to mandibles (?).

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

Caudal segment (a8) and anal lobes. Sensilla on caudal segment 10 pairs, with at least 7 pairs visible under dissecting microscope (?).

Anterior spiracles. Anterior spiracle elevated, margin convex to straight, or elevated, margin concave medially, appearing bilobed. Anterior spiracular tubules 13–17 (range estimated, LEC coded 15); in a single uniform row, or in a single irregular row (?).

Posterior spiracles. Posterior spiracular area not distinctly set off from caudal segment. Posterior spiracles: slits 2.5–3.5x longer than wide (range estimated, LEC coded about 3). Dorsal spiracular processes with numerous trunks arising from an elongate base (long processes). Number of dorsal spiracular processes 9–13. Number of ventral spiracular processes 9–13. Number of lateral spiracular processes 4–6. Area between posterior spiracles smooth.

Host plants. Loganiaceae, Solanaceae.

Part of plant attacked: fruit.

Biogeographic region. Afrotropical.

Specimens examined. Based on description by White and Elson-Harris (1992; South Africa: ex Strychnos pungens Soler., (n=1)).

Sources of data and SEM numbers: (Pterandrus)305SEM.
