Anastrepha tumbalai Tigrero & Salas

Morphology

Body. Setae dark red brown, or dark brown to black (cafe oscuro (Tigrero & Salas 2007)).

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 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.

Thorax. Mesonotum length 2.4–3.3 mm (2.85, n=1 (Tigrero & Salas 2007)). 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 well developed, at least half as large as anepimeral seta. Mesonotum yellow, or orange. Scutum with 2 (sublateral) pale postsutural vittae, or with 3 (both medial and sublateral) pale postsutural vittae (without defined medial vitta in holotype (Tigrero & Salas 2007)). Scutum posteriorly without brown or orange brown markings. 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 entirely yellow to orange. Mediotergite entirely yellow to orange.

Wings. Wing length 5.55–6.55 mm (6.047(Tigrero & Salas 2007)). 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 separated (broadly by hyaline band from cell bm to costal margin in cell r1). 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; extending more than 1/3 distance from apex of vein Cu1 to apex of vein A1+Cu2, or extending less than 1/3 distance from apex of vein Cu1 to apex of vein A1+Cu2; 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, or connected to proximal arm of V band. Vein R2+3 not sinuous; without accessory vein. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Oviscape length 3.75–4.4 mm (4.072 (Tigrero & Salas 2007)); ratio (oviscape length/mesonotum length) 1.25–1.6 (1.43 (Tigrero & Salas 2007)). Aculeus length 3.3–3.7 mm (3.50 (Tigrero & Salas 2007)). Aculeus length/oviscape length 0.8–0.95 (0.86 (Tigrero & Salas 2007)). Aculeus tip length 0.23–0.28 mm (0.256 (Tigrero & Salas 2007)); width 0.04–0.05 mm (0.045 (Tigrero & Salas 2007)); length/width in ventral view 5.2–6 (5.63 (Tigrero & Salas 2007)); lateral margins not curved dorsally; flared outward at or proximal to base, lateral margin strongly concave; without ridges or lobes; without elongate dorsolateral depressions apically; with minute serration, visible only with compound microscope, or with fine serrations. Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
