Diagnosis. In the key of Steyskal (1977), A. arevaloi runs to A. chiclayae Greene or A. pseudoparallela (Loew) , and in that of Zucchi (2000) it runs to A. alveatoides Blanchard. It can be distinguished from the former two species by seta color (orange vs. brown), scutal microtrichia, and its shorter aculeus tip (0.20–0.25 vs. 0.29–0.35 or 0.35–0.50 mm long). It differs from A. alveatoides in its relatively longer oviscape (0.65–0.90 vs. 0.52–0.57 times as long as mesonotum), longer aculeus (1.78–2.05 vs. 1.64–1.72 mm long), and narrower (0.11–0.13 vs. 0.20–0.23 mm wide) and less serrate aculeus tip. In the shape of the aculeus tip it resembles A. barrettoi Zucchi , which differs in having longer terminalia (oviscape 4 mm long, aculeus 3.75 mm long), and A. nascimentoi Zucchi , which differs in the shape of the aculeus tip (1.00–1.30 vs. 1.53–1.92 times as long as wide) and in having the serrations of the tip extended beyond its basal margin. A. arevaloi is also similar to A. xanthochaeta Hendel and A. similis Greene , which have the C- and S-bands separated, the oviscape greater than 2.3 mm long, and the aculeus tip less serrate. Anastrepha similis further differs in having red brown to dark brown setae.

Description. Mostly yellow to orange. Setae pale orange to orange brown.

Head: Yellow to orange except brown ocellar tubercle. 2–3 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most 2 times longer than ocellar tubercle. Facial carina, in profile, slightly concave on dorsal two-thirds. Antenna not extended to ventral facial margin. Palpus in lateral view dorsally curved, evenly setulose.

Thorax ( Fig. 1 ): Mostly yellow to orange, without brown markings; with following areas white to pale yellow [not well differentiated in type specimens]: postpronotal lobe and lateral margin of scutum bordering it; sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; scutellum; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite; medial vitta absent anteriorly, but diffuse whitish rectangular area present between dorsocentral setae. Subscutellum and mediotergite entirely pale yellow to orange. Mesonotum 2.00– 2.88 mm long. Postpronotal lobe, notopleuron, scutum and scutellum entirely microtrichose; scutal setulae yellow to orange. Chaetotaxy typical for genus. Katepisternal seta usually weak, yellowish, at most 0.67 times length of anepisternal seta, usually less than half as long.

Legs: Entirely yellow to orange.

Wing ( Fig. 5 ): Length 5.75–7.33 mm, width 2.58–3.32 mm, ratio 2.23–2.47. Apex of vein R 1 at 0.51–0.53 wing length, proximal to level of anterior end of crossvein r-m. Cell c 1.16–1.38 times as long as pterostigma; pterostigma 2.87–3.73 times as long as wide. Vein R 2+3 not sinuous. Crossvein r-m at 0.65–0.7 distance from bm-m to dm-m on vein M 1. Vein M 1 moderately curved apically; cell r 4+5 0.76–0.96 times as wide at apex as at level of dm-m. Cell cu a with distal lobe relatively short, length of cu a 1.26–1.63 times as long as anterior margin, lobe 0.62–0.89 times as long as vein CuA+CuP. Wing pattern mostly orange and moderate brown. C-band mostly orange, without hyaline area in cell c, distal margin in cells r 1 and r 2+3 narrowly brown, pterostigma mostly moderate brown. C-band and S-band connected along vein R 4+5; hyaline marginal spot in cell r 1 triangular to subquadrate, with apex aligned proximal to crossvein r-m. Basal hyaline area in cell dm small. Basal half of S-band mostly orange, posterodistal margin partly to mostly narrowly brown, more broadly in cell m 4 but brown not reaching apex of cell cu a, without incision in cell m 4; distal section narrowly brown on most of margins, relatively broad, at apex of vein R 2+3 0.68–0.73 times width of cell r 2+3, not extended to apex of vein M 1, without marginal hyaline areas; hyaline area proximal to apex of band extended to vein R 2+3. V-band with proximal arm narrow, mostly orange, margins in cells dm and m and sometimes in r 4+5 narrowly brown, and entire part in cell m 4 brown; separated from S-band along vein R 4+5; on posterior wing margin extended approximately three-fourths distance to vein CuA+CuP; distal arm slender, brown except anteriorly, broadly connected to proximal arm, hyaline area between band and vein M 1 absent or very small, extended at most one-fifth across cell.

Abdomen: Mostly orange, without brown markings.

Male terminalia ( Figs. 41–42 ): Epandrium in lateral view shorter than high, in posterior view without V-shaped medial indentation in posterodorsal margin. Lateral surstylus relatively long, extended beyond prensisetae by 2.60– 3.25 times length of prensiseta; in lateral view elongate, apex slender and posteriorly curved; in posterior view with medial margin convex, lateral margin straight or slightly concave or convex. Proctiger with lateral and ventral sclerotized areas separated. Phallus 2.40–2.78 mm long, 0.87–1.03 times as long as mesonotum; glans 0.4–0.6 mm long.

Female terminalia ( Figs. 17–18 , 22 , 30–31 ): Oviscape 1.84–2.22 mm long, 0.65–0.9 times as long as mesonotum, straight in lateral view; entirely orange; spiracle at basal 0.31–0.40. Eversible membrane ( Figs. 17–18 ) with dorsobasal denticles in subtriangular pattern, with approximately 25–30 relatively short hooklike denticles in 4–5 V-shaped rows. Aculeus ( Fig. 22 ) slightly ventrally curved in lateral view, 1.78–2.05 mm long, 0.94–1.00 times oviscape length; in ventral view base distinctly expanded, 0.17–0.24 mm wide, shaft 0.11–0.13 mm wide at midlength; tip ( Figs. 30–31 ) 0.20–0.25 mm long, 0.10–0.13 times aculeus length, 0.11–0.15 mm wide, 1.53–1.92 times as long as wide; in ventral view slightly expanded or parallel-sided basally, distal 0.74–0.91 triangular, very finely serrate, lateral margin of triangular part straight or slightly convex; 0.04–0.05 mm wide in lateral view, 0.31–0.42 times ventral width. Spermathecae not examined.

Distribution. Anastrepha arevaloi is known only from Colombia (Antioquia, Caldas, Cesar, Cundinamarca, Risaralda and Santander Departments, Eastern and Central Cordilleras between 526–2400m elevation).

Biology. The host plants and other aspects of the biology of this species are unknown.

Etymology. This species is named in honor of Emilio Arévalo Peñaranda, in recognition of his contributions to our knowledge of the Colombian Anastrepha fauna.

Comments. This species is tentatively placed in the pseudoparallela species group due to its similarity to A. xanthochaeta Hendel.
