Anastrepha mikuymono Tigrero

Morphology

Body. Setae dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 4–5. Orbital setae 1. Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3.

Thorax. Mesonotum length 2.9–3.25 mm (2.98–3.18 (Tigrero 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; without pale spot or vitta on presutural lateral margin of scutum or posterior part of notopleuron. Scutum presutural dorsocentral pale vitta absent; with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta with posterior end ovoid; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. 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. Femora entirely yellow to orange.

Wings. Wing length 7.1–8.1 mm (7.53–7.68 (Tigrero 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). Cell c mostly or entirely infuscated to subhyaline, or paler posteriorly, without distinct subapical hyaline area. C-band broadly extending to vein M in cell br along cell bm; covering base of cell r2+3, or not covering base of cell r2+3 (base of r2+3 appears almost entirely hyaline in Tigrero (2007) figs. 8–9, but specimens also appear to be teneral); 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 along veins R2+3 and R4+5 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 (sometimes with short projection but well separated from wing margin (Tigrero 2007, fig. 9)); 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 (broad and relatively narrowly separated from base of S-band in figs. 8–9 of Tigrero (2007)); not connected anteriorly to S-band; not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band. Cell c: pterostigma ratio (cell c length/pterostigma length) 0.85–1.05 (0.95, measured on Tigrero 2007, fig. 9). Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.52–0.58 (0.55, measured on Tigrero 2007, fig. 9). 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) 0.65–0.69 (0.67, measured on Tigrero 2007, fig. 9). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.8–1.1 (0.95, measured on Tigrero 2007, fig. 9). 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. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in posterior view not boot-shaped. Surstylus in posterior view with lateral margin concave. Surstylus in posterior view with mesal margin convex. Lateral surstylus in lateral view flattened, slightly curved, apex acute. Glans present. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally (tentatively scored from Tigrero 2007 fig. 11). Oviscape entirely yellow to orange brown; straight; length 3.4–3.95 mm (3.57–3.80 (Tigrero 2007)); length ratio (oviscape length/mesonotum length) 1.1–1.3 (1.19–1.20 (based on ratio of shortest/ shortest and longest/ longest values of oviscape and mesonotum lengths given by Tigrero (2007))). Aculeus length 3.2–3.6 mm (3.28–3.50, Tigrero 2007). Aculeus tip length 0.23–0.28 mm (0.25–0.26, Tigrero 2007); width 0.1–0.13 mm (0.11–0.12, Tigrero 2007); length/width in ventral view 2–2.35 (2.16–2.20 (based on ratios of shortest/shortest and longest/longest values given by Tigrero 2007)); 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.
