| | Pest fruit flies of the world – larvae |
Body length 11–15mm (range estimated, LEC coded as 13); slender, elongate, tapering anteriorly (?). Integument unsclerotized, entirely whitish to yellowish. Caudal ridge present. Mature larvae able to jump (?).
Head. Head of normal shape; cephalic lobes well developed. Antenna 2-segmented. Stomal organ: primary lobe small, round (?); other peg-sensilla-like structures ?. Stomal region: secondary lobes present, medial ones elongate, like oral ridges (?); sclerotized stomal guards absent (?). Oral ridges present; number of oral ridges 17–19 (some branched); margins scalloped (long, deeply serrated, parallel-sided, bluntly rounded teeth ?). Accessory plates present (numerous, long ?); margins serrated (deeply serrated; ?). Elongate, finger-like lobes arising above mandibles absent (?). Labium broad (?).
Cephalopharyngeal skeleton. Mandibles: subapical teeth present; tooth much smaller than apical tooth, and delicate, or smaller than apical tooth, and very stout, or about the same size as apical tooth (?); with a single ventral tooth (?); base ?. Parastomal bars elongate, free from hypopharyngeal sclerite (?). Dental sclerites present, posterior to mandibles (?).
Spinules and creeping welts. Dorsal spinules on segments T1-A1, or T1-A2.
Caudal segment (a8) and anal lobes. Sensilla on caudal segment 10 pairs, with at least 7 pairs visible under dissecting microscope (?).
Anterior spiracles. Anterior spiracular tubules 23–25; in a single uniform row, or in a single irregular row (?).
Posterior spiracles. Posterior spiracular area not distinctly set off from caudal segment. Area between posterior spiracles smooth.
Host plants. Cucurbitaceae.
Part of plant attacked: fruit.
Biogeographic region. Afrotropical.
Specimens examined. Based on description by Silvestri (1913). Sources of data and SEM numbers: 334.
Illustrations. • Head (anteroventral).
We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
