Diagnosis. Anastrepha intermedia differs from most other species of Anastrepha in having the facial carina produced and convex near its midheight, a complete S-band that is broadly fused to the C-band along the costa with no distinct marginal hyaline mark in cell r1, and the V-band complete. It differs from all other species of Anastrepha except A. neogigantea in having uneven setation of the palpus, a flattened preapical expansion on the male arista, and the complex shape of the lateral surstylus. It differs from A. neogigantea in having the V-band complete, from A. gigantea Stone, which has a similar facial carina and wing pattern, in having the V-band separate from the Sband, and from both species in having the scutum and scutellum entirely microtrichose, and much shorter terminalia. The area distal to the apex of vein R1 is often diffusely paler than adjacent parts of the bands, but there is no distinct hyaline mark. Anastrepha intermedia differs from species of the grandis group, which also lack a hyaline mark distal to the apex of vein R1, in having the distal arm of the V-band complete.
Description. Mostly yellow to orange, with white to pale yellow markings. Setae dark red brown to black. Head (Figs. 13–16): Yellow to orange except ocellar tubercle brown. 3–4 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most 1.5 times as long as ocellar tubercle. Facial carina, in profile, strongly produced and convex near midheight. Antenna extended ca. 0.67 distance to ventral facial margin. Female arista (Fig. 14) filiform; male arista (Fig. 13) with short triangular preapical expansion. Palpus (Fig. 16) in lateral view parallel-sided or slightly expanded on apical half, rounded truncate apically, unevenly setulose, with subapical ventral area with denser and some larger setulae, apical bare area, and 2–3 larger marginal apical setulae.
Thorax: Mostly yellow to orange, without brown markings, with following areas white to pale yellow (sometimes poorly differentiated in dry specimens): postpronotal lobe and lateral margin of scutum bordering it, not extending onto notopleuron; medial scutal vitta, slender except posterior sixth slightly expanded and rounded, extended laterally beyond acrostichal seta but not to dorsocentral seta; sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; entire scutellum; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite. Subscutellum and mediotergite entirely orange. Mesonotum 4.00– 5.04 mm long. Postpronotal lobe, scutum, and scutellum entirely microtrichose; scutal setulae yellowish anteromedially, pale brownish posteriorly and laterally. Chaetotaxy typical for genus. Anepimeral seta sometimes relatively weak. Katepisternal seta weak, at most three-fifths as long as anepisternal seta, but much weaker, yellowish to reddish brown.
Legs: Entirely yellow to orange.
Wing (Figs. 29, 30): Length 10.23–12.10 mm, width 3.55–4.32 mm, ratio 2.76–2.90. Apex of vein R1 at 0.58–0.60 wing length, slightly proximal to or aligned with level of anterior end of crossvein r–m. Cell c 1.02–1.21 times as long as pterostigma; pterostigma 5.53–6.74 times as long as wide. Vein R2+3 not sinuous. Crossvein r–m at 0.66–0.69 distance from bm–cu to dm–cu on vein M. Vein M moderately curved apically; cell r4+5 0.91–1.04 times as wide at apex as at level of dm–cu. Cell bcu with distal lobe moderately long, length of bcu 1.50–1.65 times as long as anterior margin, lobe 0.72–0.85 times as long as vein A1+Cu2. Wing pattern mostly orange and orange brown. C-band mostly orange, slightly darker orange brown in pterostigma and cell br. C-band and S-band extremely broadly connected between costa and vein R4+5; cell r1 without distinct marginal hyaline area distal to apex of vein R1 although this area often paler or diffusely subhyaline. Hyaline area in cell br large and elongate, reaching or narrowly separated from vein R4+5 and 1.5–2.0 times as long as distal colored area of cell; cell dm with basal hyaline area large. Basal half of S-band mostly orange, most of section in cell cu1, except extreme base, and margins, except proximal margin in cell dm, orange brown to moderate brown, without or with weak incision in cell cu1; distal section orange to orange brown, broad, at apex of vein R2+3 0.83–0.90 times width of cell r2+3, slightly to distinctly broadening or even in width, separated from apex of vein M; hyaline area proximal to apex of band extending to or more commonly almost to vein R2+3. V-band complete; proximal arm of medium width, mostly orange brown to moderate brown, fading anteriorly in cell r4+5, separate from S-band anteriorly, on posterior margin with faint, diffuse proximal extension half distance to vein A1+Cu2; distal arm complete, broadly connected to proximal arm anteriorly, apex of V-band sometimes fainter than rest of band, relatively broad, with small or no hyaline area between band and vein M.
Abdomen: Mostly orange, without brown markings. Setulae brown.
Male terminalia (Fig. 104, 105): Lateral surstylus relatively short, extended beyond prensisetae by ca. 1.5 times length of prensiseta; complex, in lateral view thin but folded, subbasally sometimes with acute ridge on anterior margin curving posteriorly and extending to about midlength, and with second acute ridge beginning near midlength on anterior margin, curving to posterior margin and back to anterior margin apically; in posterior view clearly delimited basally from epandrium, broad, on basal half with lateral margin evenly convex, extending mesally to form ridge, crossed by more distal and posterior ridge forming lateral margin distally, convex then strongly concave; mesal margin gradually convex. Proctiger with ventral and lateral sclerotized areas connected but lateral areas separate dorsally. Phallus 3.80–4.20 mm long, 0.88–0.94 times as long as mesonotum; glans 0.71 mm long, ca. 6 times as long as wide.
Female terminalia: Oviscape 3.08–3.60 mm long, 0.69–0.77 times as long as mesonotum, straight in lateral view, entirely yellow to orange; spiracle at basal 0.31–0.38. Eversible membrane (Fig. 52) with numerous short stout denticles and 50–70 medium length hooklike dorsobasal denticles in 6–7 V-shaped rows in subtriangular pattern. Aculeus (Figs. 73, 74) straight in lateral view, 1.78–1.98 mm long, 0.54–0.60 times as long as oviscape, in ventral view base strongly expanded, 0.27–0.32 mm wide; shaft 0.085–0.100 mm wide at midlength; tip (Fig. 87) 0.25–0.29 mm long, 0.14–0.15 times aculeus length, 0.090–0.105 mm wide, 2.60–2.89 times as long as wide, very weakly constricted basally or weakly expanded subbasally, lateral margin slightly convex and gradually tapered to blunt apex, nonserrate, 0.07–0.08 mm wide in lateral view, 0.71–0.80 times ventral width. Spermathecae not examined.
Distribution. Anastrepha intermedia is known only from Panamá.
Biology. The only known host plant is Pouteria buenaventurensis (Aubrév.) Pilz (Sapotaceae), which is known from Panamá, Colombia and Ecuador (TROPICOS database). The larvae feed inside the large seeds (Figs. 114, 115).

Etymology. The name of this species is a Latin adjective meaning between, in reference to its uncertain relationships.
Comments. Anastrepha intermedia is most closely related to A. neogigantea based on the setation of the palpus, the preapical expansion on the male arista, and the complex shape of the lateral surstylus, which are all apomorphic states that are unknown in other species of Anastrepha and other Toxotrypanini. The latter two character states could possibly occur in A. gigantea Stone, in which the male is unknown. The broad marginal connection of the C-band and S-band, which is uncommon in Anastrepha (only in A. bezzii Lima, the grandis group, and some species of the daciformis group), is probably a synapomorphy for A. gigantea, A. intermedia and A. neogigantea. These three species are here tentatively included in the benjamini species group (see Norrbom 1997, Norrbom et al. 1999b) based on their medially produced facial carina. This character state is apomorphic, but other characters suggest that it has arisen independently in A. grandicarina, here tentatively placed in the grandis group, and some species of the pallidipennis clade within the pseudoparallela group, so further testing of the monophyly of the benjamini group is warranted. The terminalia in A. neogigantea are elongate as in other species of the benjamini group, but they are much shorter in A. intermedia.
