Anastrepha striata Schiner

Recognition
Anastrepha striata differs from all other species of Anastrepha except A. bistrigata Bezzi in having the dorsal posterior margin of the epandrium with a narrow, V-shaped, medial indentation, and by by the following combination of characters: mesonotum with large, somewhat U-shaped, brown area, often interrupted at transverse suture, but without other brown markings; mediotergite and subscutellum entirely brown or at least brown laterally; thoracic pleuron and abdomen without brown areas; and scutum microtrichose, with broad nonmicrotrichose stripe, sometimes interrupted at transverse suture, on dorsocentral line. These two species share additional characters, including: wing bands, particularly middle section of S-band, mostly orange brown; cell br with hyaline area posterior to pterostigma extending width of cell, reaching vein R₄₊₅; aculeus tip broad, at least 0.17 mm wide, and bluntly triangular; and lateral surstylus with rounded subapical lateral lobe. Anastrepha striata differs from A. bistrigata by the following characters: oviscape less than 2.8 mm long, less than 0.90 times mesonotum length; aculeus less than 2.5 mm long; scutum with brown areas usually interrupted at transverse suture; setulae usually strongly contrasting white and dark brown, absent on narrow area lateral to postsutural nonmicrotrichose area; distal section of S-band slightly narrowed to moderately broad, at apex of vein R₂₊₃ 0.44-0.63 times width of cell r_2+3; aculeus tip 0.24-0.31 mm long; and lateral surstylus slightly longer and narrower and more or less parallel to the opposite surstylus. The scutal microtrichia are usually denser and whiter in appearance in oblique anterior view than in A. bistrigata, and the wing bands are usually slightly paler.

The third stage larva is very similar to that of A. bistrigata. These two species differ from the larvae of the other Anastrepha species described to date by the following combination of characters: dorsal spinules separate, conical, in fewer than 5-6 rows on meso- and metathorax, but present on first, second, and usually third abdominal segments; anterior spiracle with 12-23 tubules; posterior spiracular processes SP-I and SP-IV with average of 13-23 trunks and 23-49 tips, hair length at least one-third length of spiracular opening  (Steck et al. 1990).

Description
Body largely orange with dark brown and yellow markings. Setae redbrown to dark brown.

Head: Yellow except ocellar tubercle brown. Facial carina, in profile, concave. 3-6, usually 4-5, frontal setae; 2 or rarely 1 orbital setae (posterior seta absent on one side in 2 of 25 specimens sampled), posterior seta well developed. Ocellar seta weak and small or minute. Antenna extended 0.70-0.85 distance to lower facial margin.

Thorax: Mostly orange with following areas yellow and often contrasting: postpronotal lobe; single medial and paired sublateral vittae on scutum, the slender medial vitta extended nearly full length of scutum, broadened posteriorly, extended laterally half to 3/4 distance from level of acrostichal seta to that of dorsocentral seta; sublateral vitta extended from transverse suture almost to posterior margin, including intra-alar seta; scutellum except extreme base of disc (brown area well separated from basal seta); propleuron; dorsal margin of anepisternum; dorsal half of greater ampulla; dorsal margin of katepisternum; katepimeron; and most of anatergite and katatergite. Mesonotal pattern with following orange areas: broad area bordering medial vitta, usually small sublateral presutural area, usually narrow area bordering mesal margin of sublateral vitta, and area lateral to sublateral vitta except extreme posterior margin. Dark brown, somewhat U-shaped mark narrowed or usually interrupted at or anterior to transverse suture. Darker areas of pleuron orange. Subscutellum and mediotergite dark brown, narrowly to broadly orange medially. Mesonotum 2.91-3.41 mm long. Scutum with microtrichia relatively dense giving white appearance when viewed from oblique anterior angle; with short medial presutural bare area sometimes (Brazilian and Bolivian specimens examined) extended narrowly along medial vitta as far as transverse suture; always with broad nonmicrotrichose areas on parts of dark brown marks, 1 presutural, 1 postsutural between medial and sublateral vittae and extended to or almost to level of dorsocentral seta; these areas usually well separated at transverse suture, but rarely narrowly connected (one female, Huitanaã, Brazil, CMP, USNM00053080); setulae usually strongly contrasting, whitish medially, dark brown on and lateral to nonmicrotrichose areas except for patch of white setulae on lateral part of presutural nonmicrotrichose area; brown setulae especially dense on nonmicrotrichose areas on brown marks and sparse to absent on narrow area lateral to postsutural nonmicrotrichose area. Katepisternal seta moderately developed, weaker than but longer than postocellar seta, pale to dark brown.

Wing: Length 6.41-7.32 mm. Vein M strongly curved apically; section between BM-Cu and R-M 1.83-2.44 times as long as section between R-M and DM-Cu; section between R-M and DM-Cu 0.75-0.91 times as long as DM-Cu. Crossvein DM-Cu oblique, with anterior end more distal than posterior end. Pattern mostly yellow to orange brown and moderate brown. C-band and S-band usually narrowly connected or separated, occasionally broadly connected, along vein R₄₊₅; often connected in cells r₁ and/or r₂₊₃; separated basally by hyaline area extending width of cell br and aligned with pterostigma, and covering basal seventh to fourth of cell dm and all of cell bm. C-band with cell bc and most of cell c yellowish, the latter sometimes subhyaline medially or darker anteriorly and basally; with large yellow area in base of cell sc and cells r₁ and r₂₊₃ posterior to pterostigma, extending distally to or almost to level of apex of vein R₁; most of pterostigma, usually narrow distal margin, and base of cell br dark orange brown to moderate brown. S-band with middle section between costa and vein Cu₁ largely yellow to orange with narrow brown margins, darkening distally; distal section of band slightly narrowed to moderately broad, at apex of vein R₂₊₃ 0.44-0.63 times width of cell r₂₊₃; separated from apex of vein M. Hyaline spot in cell r₁ nearly triangular, sometimes extended to vein R₄₊₅, but often interrupted in cell r₁ or r₂₊₃ or absent in r₂₊₃; its apex aligned distinctly basal to R-M. V-band with distal arm usually complete and connected to proximal arm, but often fainter anteriorly, sometimes (especially in specimens from Guianas and northern Brazil) partially to entirely absent; proximal arm usually extended to vein R₄₊₅, often fainter in cell r₄₊₅; separated from S-band; extended basally along posterior wing margin almost to vein A₁+Cu₂ but not connected to extension from base of S-band.
