### Anastrepha zernyi Lima

Body. Setae golden to pale orange, or orange, or orange brown.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 2–4 (3, n=2). Orbital setae 2. 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. Face without whitish markings. Antenna not extended to ventral margin of face. Palpus in lateral view evenly setulose.

Thorax. Mesonotum length 3.5–4.2 mm (3.80–3.91, n=2). 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. Mesonotum yellow, or orange. Scutum posteriorly without brown or orange brown markings, or with pair of brown spots or markings, or with brown or orange brown band or other transverse marking or larger posteromedial mark. Scutum posteriorly with only pair of ovoid brown spots on or slightly lateral to dorsocentral line; with dark band or broad marking on posterior margin, or with irregular brown markings; scutal posterior brown band not extended laterally to include intra-alar seta; 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 7.8–9.8 mm (8.5, Stone 1942a; 9.0, Lima 1934). 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; 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. Cell bm entirely hyaline or infuscated only along subapical fold. S-band posterior margin without incision in cell cu1, or with weak incision in cell cu1. 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. S-band middle section predominantly or entirely orange, often with brown margins. Subapical hyaline area in radial cells distal to r-m extending anteriorly into cell r1, or 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; 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, or incomplete, not reaching vein R4+5, but extended from vein M to wing margin, or present only in cell m (presumed variation), or absent (presumed variation); isolated, not connected to proximal arm of V-band or to S-band. S-band distal section width ratio (width of S-band/width of cell r2+3, both measured perpendicular to costal margin at apex of vein R2+3) 0.4–0.65 (0.49, n=1). 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) 1.1–1.4 (1.24, n=1). Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.59, n=1. 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. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.66–0.71 (0.68, n=1; 0.69, Lima 1934, fig. 3). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.6–0.9 (0.74, n=1). 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 without brown markings. Lateral surstylus in posterior view not boot-shaped. Glans absent. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape entirely yellow to orange brown; straight; length 3.5–4.5 mm (4.01, n=1); length ratio (oviscape length/mesonotum length) 0.95–1.15 (1.06, n=1); spiracle ratio (distance from base to spiracle/oviscape length) 0.26, n=1; spiracle ratio to mesonotum length (distance from base to spiracle/mesonotum length) 0.28, n=1. Eversible membrane with dorsobasal denticles all small, weakly developed, in triangular to semicircular pattern. Aculeus length broken, tip missing in examined specimen. Aculeus tip width 0.02–0.04 mm (presumed to be as in other species of dentata group).

Miscellaneous. Sex of recorded specimens: male and female. Species group: dentata group.

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

Illustrations. • Terminalia, female.

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.
