Anastrepha manizaliensis Norrbom & Korytkowski

Morphology

Body. Setae dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 4–6. 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. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 2.57–3.65 mm. 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. Katepisternal seta moderately developed, larger than postocellar seta, but much smaller and weaker than anepimeral 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; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly with only single medial brown spot on scuto-scutellar suture. 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 yellow to red brown medially, dark brown laterally. Mediotergite entirely yellow to orange, or entirely brown to dark brown (rarely; 2 of 37 specimens brown dorsolaterally).

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). 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 (narrowly along R4+5 (32 of 38 specimens), cell r1 with basomarginal hyaline spot), or separated (by hyaline band from cell bm to costal margin distinctly narrowed along R4+5). Cell r1 basomarginal hyaline spot triangular to quadrate. 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. 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; extending more than 1/3 distance from apex of vein Cu1 to apex of vein A1+Cu2; not connected anteriorly to S-band. V-band distal arm complete; connected to proximal arm of V band (usually), or 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) 0.5–0.65 (0.53–0.60, n=5). Vein R2+3 without accessory vein. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.66–0.72 (0.67–0.71). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Phallus length 4.5–4.7 mm; ratio (phallus length/mesonotum length) 1.3–1.55. Glans present; without spinules. Proctiger lateral and ventral sclerotized areas separate, lateral areas separate dorsally. Oviscape straight; length 2.65–3.4 mm; length ratio (oviscape length/mesonotum length) 0.8–1.1 (0.86–1.05, n=17). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Aculeus length 2.7–3.3 mm (n=15). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.5–0.66 mm (n=15); width 0.16–0.19 mm (n=14); lateral margins not curved dorsally; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with fine serrations, or with medium sized serrations; serrated part 0.39–0.49 times length of tip. Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration. Spermathecae sclerotized.
