### Anastrepha lutea Stone male

Body. Setae dark red brown, or dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–4. Orbital setae 2, or 1 (rarely). Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face with ventral part gradually tapered laterally; without brown markings. Antenna not extended to ventral margin of face. Arista of male without preapical expansion. Palpus in lateral view evenly setulose.

Thorax. Mesonotum length 2.9–3.75 mm. Postpronotal lobe and notopleuron entirely microtrichose. Scutum mostly or entirely microtrichose. Scutellum disc entirely microtrichose. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length; postpronotal seta on posterior half of postpronotal lobe. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Katepisternal seta weak, no larger than postocellar seta. Mesonotum yellow, or orange. Scutum presutural dorsocentral pale vitta absent; with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta narrow posteriorly, not expanded, or with posterior end ovoid (extended laterally to or slightly beyond acrostichal seta); pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings. Scutum without brown vittae. Scutellum entirely yellow or with dark markings only on extreme base of disk. Mesopleuron mostly yellow to orange, without brown markings. Subscutellum entirely yellow to orange. Mediotergite entirely yellow to orange. Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.

Wings. Wing length 7.25–7.9 mm. Wing pattern without typical bands. C-band broadly extending to vein M in cell br along cell bm. Cell bm entirely infuscated. 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. Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. Area between S-band and V-band entirely microtrichose in cells dm and cu1. Cell c: pterostigma ratio (cell c length/pterostigma length) 1.11–1.23. Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.53–0.58. Vein R2+3 not sinuous; without accessory vein. Vein R4+5 distal to crossvein r-m more or less evenly curved or not strongly bowed medially, or strongly bowed slightly distal to level of anterior end of crossvein dm-cu. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.66–0.70. Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.9–1.2 (0.96–1.14). Cell bcu ratio (length/anterior margin length along vein Cu) 1.43–1.57. Cell bcu posteroapical lobe shorter than vein A1+Cu2. Costa in male with setulae on anterior margin between crossvein h and apex of vein R1 similar to other setulae. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdomen ovate or parallel-sided, syntergite 1+2 gradually broadening or parallel-sided. Abdominal tergite with brown markings. Abdominal tergites dark brown on anterior half of tergites 3 and 4 and lateral third of tergite 5 (lateral margins of tergites 3 and 4 and dark areas of tergite 5 with large blackish setae); with dense silvery white microtrichia on white areas, nonmicrotrichose on brown lateral areas of tergite 5. Epandrium posterodorsal margin evenly rounded. Lateral surstylus in posterior view without basolateral lobe. Phallus length 4.95–5.5 mm; ratio (phallus length/mesonotum length) 1.33–1.95 (1.41–1.90). Glans present; with minute spinules apically. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally.

Miscellaneous. Other names for this species: Anastrepha bellicauda Norrbom. Data source: Norrbom & Korytkowski 2007. Sex of recorded specimens: male. Species group: schausi 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.
