### Anastrepha matertela Zucchi

Thorax. Mesonotum length 3.2–3.8 mm (3.5, n=1, Zucchi 1979). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Subscutellum yellow to red brown medially, dark brown laterally. Mediotergite yellow to red brown medially, dark brown laterally.

Wings. Wing length 7.25–8.75 mm (8.0, n=1, Zucchi 1979). Wing pattern typical Anastrepha pattern (S-band complete or at most interrupted at crossvein r-m, C-band and at least proximal arm of V-band present). C-band broadly extending to vein M in cell br along cell bm; covering base of cell r2+3; yellow or orange area posterior to pterostigma broad, extending distally into cells r1 and r2+3 at least to level of midlength of pterostigma. C-band and S-band connected (along vein R4+5, cell r1 with basomarginal hyaline spot). Basal hyaline area between C-band and S-band extended to vein R4+5. Cell r1 basomarginal hyaline spot triangular to quadrate. Cell r1 basomarginal hyaline spot apex aligned proximal to crossvein r-m. S-band extended anteriorly to vein R4+5 and covering all of crossvein r-m. S-band base without extension in middle of cell cu1 to posterior wing margin; without extension in cell a1 to or almost to posterior margin, or with extension in cell a1 to or almost to posterior margin (Zucchi 1979, fig. 15 shows extention but needs verification). Subapical hyaline area in radial cells distal to r-m extending anteriorly to vein R2+3. S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. S-band distally not extended to apex of vein M. V-band proximal arm as dark as apical half of S-band; extending more than 1/3 distance from apex of vein Cu1 to apex of vein A1+Cu2; connected anteriorly to S-band along vein R4+5 or in cell r2+3; not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band. Vein R2+3 not sinuous; without accessory vein.

Abdomen. Oviscape length 2.5–3 mm (2.75, n=1, Zucchi 1979); ratio (oviscape length/mesonotum length) 0.5–0.65 (0.57, n=1, Zucchi 1979). Aculeus length 1.8–2.2 mm (2.0, n=1, Zucchi 1979). Aculeus tip not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with medium sized serrations, or with large serrations; serrated part 0.65–0.75 times length of tip (0.69, estimated from Zucchi 1979, fig. 4). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.

Miscellaneous. Data source: Zucchi 1979. Sex of recorded specimens: female. Species group: fraterculus group.

Biology and economic significance. This species is not considered economically important. Refer to the 'Tephritidae Databases' in the USDA Compendium of Fruit Fly Host Information (https://coffhi.cphst.org/) for host plant information.

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.
