### Anastrepha murrayi Norrbom

Body. Setae orange brown, or red brown, or dark red brown.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 2–4 (3 in holotype). Orbital setae 1. 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.

Thorax. Mesonotum length 2.2–2.75 mm (2.35–2.57, n=2). Scutum entirely nonmicrotrichose. Scutellum disc mostly or entirely without microtrichia. 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 medium brown, or dark brown; with short presutural lateral pale vitta on lateral margin of scutum, not extended onto notopleuron. Scutum presutural dorsocentral pale vitta present and connected anteriorly with pale area of postpronotal lobe; with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta with posterior end bilobed; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings (scutum predominantly brown). Scutum without brown vittae. Scutellum with at least basal third of sides and disk brown or orange, distinctly darker than apex. Mesopleuron mostly yellow to orange, without brown markings. Subscutellum entirely brown to dark brown. Mediotergite entirely yellow to orange. Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.

Wings. 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). 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. S-band base without extension in middle of cell cu1 to posterior wing margin; with 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 to vein R2+3, or extending into cell r2+3 but not reaching 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 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; not connected anteriorly to S-band; not connected to S-band in cell dm. V-band distal arm absent. 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) 0.6–0.67 (0.64, 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 very short, barely extended beyond prensisetae, rounded apically. Lateral surstylus in posterior view not boot-shaped. Lateral surstylus in lateral view short, apex blunt. Phallus length 0.1–0.3 mm; ratio (phallus length/mesonotum length) 0.02–0.15. Glans absent. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape straight; length 3.5–4.2 mm (3.80–3.91, n=2); length ratio (oviscape length/mesonotum length) 1.35–1.75 (1.52–1.62, n=2); spiracle ratio (distance from base to spiracle/oviscape length) 0.19–0.25 (0.22, n=1). Eversible membrane with dorsobasal denticles mostly small and weak, apical row very large, stout, strongly sclerotized, and divided medially. Eversible membrane, subbasally on ventral side without cluster of hairs. Aculeus length 3–3.65 mm (3.24–3.40, n=2). Aculeus length/oviscape length 0.89, n=1. Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length/aculeus length 0.03–0.06 (0.044, n=1). Aculeus tip length 0.12–0.18 mm (0.15, n=1); width 0.02–0.04 mm (0.025–0.030, n=2); lateral margins not curved dorsally; slender, needle-like, with circular cross-section; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with minute serration, visible only with compound microscope, or with fine serrations; serrated part 0.1–0.33 times length of tip (0.20, n=1). Aculeus tip with serrations separated by less than width of serration. Spermathecae membranous.

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

Biology and economic significance. This species is not considered economically important. Its host plants are unknown, although it probably attacks fruits of species of Sapotaceae like other species of the daciformis species group. 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.
