Anastrepha punctata Hendel

Morphology

Head. Frontal setae 2–4. Orbital setae 2. Ocellar seta weak, small or absent. 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 2.25–3.05 mm (2.34–2.95, n=18). Scutum mostly or entirely microtrichose. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Mesonotum yellow, or orange. Scutum with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta with posterior end ovoid (usually), or with posterior end broadly quadrate; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly with pair of brown spots or markings. Scutum posteriorly with only pair of ovoid brown spots on or slightly lateral to dorsocentral line (between dorsocentral and intra-alar lines); without brown vittae (but with posterior spot). Scutellum entirely yellow or with dark markings only on extreme base of disk. 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 5.4–6.7 mm (5.48–6.64, 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). 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. 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 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 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; not connected anteriorly to S-band; not connected to S-band in cell dm. V-band distal arm complete; isolated, not connected to proximal arm of V-band or to S-band (usually), or connected to proximal arm of V band. Apex of V-band not extended from vein R4+5 to vein M, hyaline area present between band and vein M. Vein R2+3 not sinuous; without accessory vein. Vein R4+5 distal to crossvein r-m strongly bowed slightly distal to level of anterior end of crossvein dm-cu. 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.

Abdomen. Abdomen ovate or parallel-sided, syntergite 1+2 gradually broadening or parallel-sided. Abdominal tergite with brown markings. Abdominal tergites 3–5 with sublateral or lateral dark brown spots or short bands, or at least with syntergite 1+2 with dark brown band. Lateral surstylus in posterior view short and narrow, posterolaterally projected, rounded apically. Phallus length 2.25–2.85 mm (2.38–2.70, n=5); ratio (phallus length/mesonotum length) 0.78–1.15 (0.85–1.08, n=5). Glans present; without spinules. Oviscape straight; length 1.55–2 mm (1.60–1.95, n=13); length ratio (oviscape length/mesonotum length) 0.58–0.77 (0.6–0.75, n=10). Aculeus length 1.25–1.7 mm (1.33–1.55, n=13). Aculeus length/oviscape length 0.75–0.87 (0.77–0.85, n=13). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length/aculeus length 0.02–0.05 (0.03–0.04, n=6). Aculeus tip length 0.04–0.07 mm (0.05–0.06, n=6); width 0.02–0.05 mm (0.03–0.04); lateral margins not curved dorsally; gradually tapering, blade-like, with flattened cross-section, or slender, needle-like, with circular cross-section; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; not serrate; serrated part 0 times length of tip. Spermathecae sclerotized; ovoid.

Miscellaneous

Other names for this species: Anastrepha dangeloi Blanchard, Anastrepha goldbachi Blanchard, Anastrepha hendeli Greene, Anastrepha minor Lima, Anastrepha pseudopunctata Blanchard, Anastrepha pseudopunctata var. distenta Blanchard. Sex of recorded specimens: male and female. Species group: punctata group.

Biology and economic significance

This species is possibly a pest of guava (Psidium guajava L.), its only reliably recorded host. Records from other hosts are doubtful. Refer to the Fruit Fly Databases for host plant information.
