Anastrepha cryptostrepha Hendel

Morphology

Body. Setae orange, or dark red brown.

Head. Frons without brown markings except ocellar tubercle, or with paired brown mark on orbital plate, separate from mark on ocellar tubercle, or with narrow transverse or U-shaped brown mark on orbital plate and vertex, not extending to eye, connected only to posterior side of mark on ocellar tubercle. Occiput without brown marks. Frontal setae 2–3. 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 2.75–3.5 mm (2.98–3.20, n=4). Postpronotal lobe and notopleuron entirely microtrichose. Scutum nonmicrotrichose. 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. Katepisternal seta weak, no larger than postocellar seta, or absent. Mesonotum yellow, or orange. Scutum presutural dorsocentral pale vitta absent; with 2 (sublateral) pale postsutural vittae, or with 3 (both medial and sublateral) pale postsutural vittae. Scutum posteriorly with brown or orange brown band or other transverse marking or larger posteromedial mark. Scutum posteriorly with dark band or broad marking on posterior margin; scutal posterior brown band 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.

Wings. Wing length 6.75–8.25 mm (7.30–7.75, n=4). 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 small or absent, not extending beyond cell r1 nor distally beyond level of basal third of pterostigma. C-band and S-band connected (broadly along vein R4+5, cell r1 with basomarginal hyaline spot). Basal hyaline area between C-band and S-band extended to vein R4+5, or extended into cell br but not reaching vein R4+5 (more elongate anteriorly, 1.0–1.5 times as long as distal colored area of cell). Cell r1 basomarginal hyaline spot triangular to quadrate. Cell r1 basomarginal hyaline spot apex aligned with crossvein r-m, or apex aligned distal 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 with weak incision in cell cu1, or with distinct 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, 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 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; connected anteriorly to S-band along vein R4+5 or in cell r2+3 (connected broadly to very broadly); not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band, or connected to proximal arm of V-band and broadly connected with apical part of 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) 0.6–0.8 (0.69–0.70, n=4). Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. Cell c: pterostigma ratio (cell c length/pterostigma length) 0.92–0.97, n=4. Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.59–0.60, n=4. 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) 0.62–0.66, n=4. Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 1.25–1.5 (1.36–1.47, n=4). Cell bcu ratio (length/anterior margin length along vein Cu) 1.45–1.55, n=3. Cell bcu posteroapical lobe shorter than vein A1+Cu2. 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. Abdominal tergites evenly microtrichose. Epandrium posterodorsal margin evenly rounded. Phallus length 5–6.7 mm (5.67–6.00, n=2); ratio (phallus length/mesonotum length) 1.88–2.00, n=2. Glans present; without spinules. Proctiger lateral and ventral sclerotized areas connected, lateral areas connected dorsally. Oviscape at least apex brown; straight; length 3.9–4.9 mm (4.27–4.50, n=2); length ratio (oviscape length/mesonotum length) 1.25–1.55 (1.40–1.41, n=2); spiracle ratio (distance from base to spiracle/oviscape length) 0.27–0.28, n=2. Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 30–40 denticles (slender, medium length, hooklike dorsobasal denticles in 3–4 irregular rows in semicircular to subtriangular pattern). Aculeus length 3.2–4.2 mm (3.71–3.73, n=2). Aculeus length/oviscape length 0.83–0.87, n=2. Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length 0.13–0.18 mm (0.14–0.17, n=2); width 0.07–0.09 mm (0.08, n=1); length/width in ventral view 1.75, n=1; depth (width in lateral view)/width (in ventral view) 0.81, n=1; lateral margins not curved dorsally; 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. Egg egg shape unknown.
