Diagnosis. Anastrepha stangei differs from most other species of Anastrepha by its very short and simple aculeus tip. In the key of Steyskal (1977) it runs to A. edentata Stone or A. tubifera (Walker) (p. 14), but it differs from A. edentata in having the scutum mostly nonmicrotricose, from A. tubifera in having shorter terminalia (aculeus 3.05 mm long vs. 3.94 mm), and from both species in having the aculeus tip much shorter (0.06 mm long vs. 0.20–0.28 mm in A. edentata) and stouter (1.1 times as long as wide vs. 4.1 in A. tubifera). It differs from A. montei Lima and species of the panamensis group which have a somewhat similar, very short aculeus tip, in having the postpronotal lobe, notopleuron, and scutellum entirely microtrichose, the C-band and S-band separated along vein R4+5, and the denticles of the eversible membrane longer, more numerous, and continuous.
Description. Mostly yellow to orange. Setae red brown to dark red brown.
Head: Yellow to orange except brown ocellar tubercle. 3 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, slightly longer than ocellar tubercle. Facial carina, in profile, slightly convex on dorsal two-thirds. Antenna not extended to ventral facial margin. Palpus in lateral view dorsally curved, evenly setulose.
Thorax: Mostly yellow to orange, without brown markings; typical white to pale yellow areas poorly differentiated in holotype except dorsal margin of anepisternum. Subscutellum and mediotergite entirely orange. Mesonotum 2.88 mm long. Postpronotal lobe, notopleuron, and scutellum entirely microtrichose; scutum nonmicrotrichose except narrowly along transverse suture and postsutural lateral margin; scutal setulae orange. Chaetotaxy typical for genus. Katepisternal seta relatively large, 0.75 length of anepisternal seta, orange.
Legs: Entirely yellow to orange.
Wing (Fig. 37): Length 6.73 mm, width 2.78 mm, ratio 2.42. Apex of vein R1 at 0.55 wing length, proximal to level of anterior end of crossvein r–m. Cell c 1.15 times as long as pterostigma; pterostigma 4.42 times as long as wide. Vein R2+3 slightly sinuous. Crossvein r–m at 0.66 distance from bm–cu to dm–cu on vein M. Vein M weakly curved apically; cell r4+5 0.98 times as wide at apex as at level of dm–cu. Cell bcu with distal lobe moderately long, length of bcu 1.67 times as long as anterior margin, lobe 0.81 times as long as vein A1+Cu2. Wing pattern mostly orange and moderate brown. C-band mostly orange including all of cells bc and c; moderate brown in most of pterostigma; distal and posterior margins in cells r1 and r2+3 partially narrowly brown. C-band and S-band narrowly connected along vein R2+3; hyaline marginal spot in cell r1 triangular, with apex proximal to crossvein r–m. Basal half of S-band mostly orange, posterodistal margin brown, very broadly in cell cu1, without incision in cell cu1, proximal margin narrowly brown in cells br and r2+3; distal section orange except brown on margins of part bordering costa and in cell r4+5, relatively broad, at apex of vein R2+3 0.81 times width of cell r2+3, not extended to apex of vein M; hyaline area proximal to apex of band extending almost to vein R2+3. V-band complete, mostly brown except in cell r4+5, proximal arm separated from S-band, on posterior margin extended two-thirds distance to vein A1+Cu2; distal arm connected to proximal arm; cell r4+5 without hyaline area between V-band and vein M.
Abdomen: Mostly orange, without brown markings.
Female terminalia: Oviscape 3.30 mm long, 1.15 times as long as mesonotum, straight in lateral view; entirely orange; spiracle at basal 0.28. Eversible membrane (Fig. 59) with 25–30 slender, hooklike dorsobasal denticles in 3 irregular rows in subtriangular pattern. Aculeus (Fig. 79) ventrally curved in lateral view, 3.05 mm long, 0.92 times oviscape length; in ventral view base strongly expanded, 0.15 mm wide; tip (Fig. 93) 0.06 mm long, 0.02 times aculeus length, 0.055 mm wide, 1.09 times as long as wide; in ventral view bluntly triangular, nonserrate. Spermathecae not examined.
Distribution. Anastrepha stangei is known only from western Venezuela.
Biology. The host plants and other aspects of the biology of this species are unknown.
Type data. Holotype Ƥ (FSCA USNMENT 00214859), VENEZUELA: Aragua: Rancho Grande, 10°20'58"N 67°41'8"W, 4 Jul 1988, L. Stange & C. Porter.
Etymology. This species is named in honor of Lionel Stange, one of the collectors of the holotype.
Comments. Anastrepha stangei appears to belong to the mucronota species group (Norrbom et al. 1999b), in which vein R2+3 often is sinuous.
