Anastrepha maculata Norrbom

Morphology

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

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–5 (usually 3–4). 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 (2.25–2.70, n=4). Scutum mostly or entirely microtrichose. 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 yellow, or orange; with presutural lateral pale vitta on lateral margin of scutum and posterior part of notopleuron (including posterior corner) (sometimes poorly differentiated). 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 (lobes broad); pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings, or with pair of brown spots or markings. Scutum posteriorly with brown spot or vitta between postalar and intra-alar lines; without brown vittae. Scutellum with at least basal third of sides and disk brown or orange, distinctly darker than apex (orange basally, with 3 dark brown spots at midlength (1 on each side and 1 medially), sometimes narrowly connected, white apical spot occasionally divided by extension of medial dark brown spot). Mesopleuron mostly yellow to orange, with dark brown spots or bands on at least anepisternum, katepisternum and anepimeron. Subscutellum entirely brown to dark brown. Mediotergite entirely brown to dark brown, or orange with 3 dark brown vittae. Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.

Wings. Wing pattern with basal half of S-band divided into 3 parts by interruptions along veins R4+5 and Cu1 (i.e., a spot or partial band present in basal half of cell dm), 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. C-band and S-band connected along costal margin (connection extending beyond vein R2+3). S-band not extended anteriorly to vein R4+5 and not covering all of crossvein r-m (not extending anteriorly beyond vein M). Cell bm entirely hyaline or infuscated only along subapical fold. 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. Cubital streak (isolated base of S-band) entirely covering cell bcu. Cubital streak (isolated base of S-band) bordering base of vein Cu1 but not extending to dm-cu. Subapical hyaline area in radial cells distal to r-m extending into cell r2+3 but not reaching vein R2+3. S-band distally extended to apex of vein M, or not extended to apex of vein M. V-band proximal arm as dark as apical half of S-band; not connected anteriorly to S-band. V-band distal arm complete; connected to proximal arm of V band. 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) 0.53–0.62 (0.55–0.60). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Epandrium posterodorsal margin evenly rounded. 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. Glans absent. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape straight; length 2.5–2.95 mm (2.58–2.85, n=4); length ratio (oviscape length/mesonotum length) 0.95–1.25 (1.03–1.15, n=4). Eversible membrane with dorsobasal denticles mostly small and weak, apical row very large, stout, strongly sclerotized, and divided medially. Aculeus length 2.1–2.55 mm (2.33). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip 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. 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 Fruit Fly Databases for host plant information.
