### Anastrepha hamata (Loew) complex 1

Body. Setae orange, or orange brown.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–4. Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face without brown markings.

Thorax. Mesonotum length 3.6–4.8 mm (3.70–4.68, n=16). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Basal scutellar seta strong, longer than scutellum. Mesonotum yellow, or orange. Mesopleuron mostly yellow to orange, without brown markings.

Wings. Wing length 8.7–10.7 mm (8.76–10.60, n=16). 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). Cell c mostly or entirely infuscated to subhyaline, or paler posteriorly, without distinct subapical hyaline area. C-band broadly extending to vein M in cell br along cell bm. Cell bm entirely hyaline or infuscated only along subapical fold. S-band base without extension in middle of cell cu1 to posterior wing margin. Vein R2+3 without accessory vein. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Lateral surstylus in posterior view very short, barely extended beyond prensisetae, rounded apically. Lateral surstylus in posterior view not boot-shaped. Glans absent. Oviscape length 4.6–6.1 mm (4.74–5.97, n=17); ratio (oviscape length/mesonotum length) 0.95–1.45 (1.03–1.39, n=17). Eversible membrane with dorsobasal denticles all small, weakly developed, in triangular to semicircular pattern. Aculeus length 4.2–4.95 mm (4.27–4.84, n=12). Aculeus length/oviscape length 0.75–0.95 (0.79–0.91, n=12). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length/aculeus length 0.02–0.05 (0.031–0.039, n=8). Aculeus tip length 0.14–0.18 mm (0.145–0.171, n=8; difficult to measure, proximal limit of tip difficult to distinguish).

Miscellaneous. Data recording very inadequate. Sex of recorded specimens: male and female. Species group: dentata group.

Biology and economic significance. This species is not considered economically important. Both of the reported host plants belong to the family Sapotaceae. The larva feeds inside a seed within the fruit. Refer to the 'Tephritidae Databases' in the USDA Compendium of Fruit Fly Host Information (https://coffhi.cphst.org/) for host plant information.

Illustrations. • Wings. • Terminalia, female. • Terminalia, male.

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.
