Anastrepha matertela Zucchi, 1979:37 (description, wing, aculeus tip, Brazil, Bahia, Cruz das Almas); Zucchi, 1978 (in PhD thesis); Norrbom et al., 1999a:337 (in catalog); Norrbom et al., 1999b:80 (classification); Zucchi, 2000: 24 (in key); Uchôa & Pontes, 2011 (record in the state of Mato Grosso); Norrbom et al., 2012 (interactive key).

Diagnosis. This species can be recognized from other species of Anastrepha by the following combination of characters: subscutellum and mediotergite with dark brown mark on lateral margin; V-band proximal arm connected anteriorly to S-band along vein R4+5 or in cell r2+3; V-band distal arm broadly connected to proximal arm; aculeus 2.10–2.19 mm long; broadened at cloacal opening and gradually tapering distally, with medial constriction, serrated part 0.66–0.77 times length of aculeus tip. A. matertela resembles A. fraterculus (Wiedemann) , but it differs in having the aculeus and the aculeus tip longer and the serrate part more than 0.6 times length of aculeus tip, with more numerous serrations.

Description. Mostly yellow to orange. Setae dark brown.

Head. Yellow to orange except blackish ocellar tubercle. Facial carina, in profile, concave. 4–5 frontal setae; 2 orbital setae (1 in 1 of 6 specimens), posterior seta slightly more slender than anterior one; ocellar setae weak, small. Antenna not extended to ventral margin of face. Palpus in lateral view dorsally curved, evenly setulose.

Thorax. Integument mostly yellow to orange with following areas white: postpronotal lobe; medial vitta, slightly broaded posteriorly, but not extended laterally beyond acrostichal seta; paired sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; and entire scutellum; dorsal margins of anepisternum and katepisternum. Postpronotal seta on posterior half of postpronotal lobe. Scuto-scutellar suture without darker band or spot. Subscutellum and mediotergite with dark brown mark on lateral margin. Mesonotum 3.5– 4.1 mm long; 2.5–2.7 mm wide. Postpronotal lobe, scutum and scutellum entirely microtrichose. Scutal setulae yellowish. Setae dark brown. Acrostichal, dorsocentral and intra-alar setae well developed. Katepisternal seta yellowish, moderately developed but weaker than postocellar seta. Legs entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.

Wing ( Fig. 21 ). Length 7.56–8.58 mm, width 3.22–3.50 mm, ratio 2.34–2.45. Veins dark brown. Apex of vein R1 at 0.53–0.5 wing length, proximal to level of anterior end of crossvein r-m. Cell c 1.07–1.11 times as long as pterostigma; pterostigma 3.21–3.72 times as long as wide. Ratio of costa length between apices of Sc and R1/ length between apices of R1 and R2+3 0.52–0.59. Crossvein r-m at 0.64–0.67 distance from bm-cu to dm-cu on vein M. Vein M moderately curved apically, not reaching S- band; cell r4+5 1.02–1.12 times as wide at apex as at level of dm-cu. Vein R 2+3 not sinuous. Cell bcu with distal lobe moderately long, length of bcu 1.63–1.75 times as long as anterior margin, lobe 0.86–0.95 times as long as vein A1+Cu2. Pattern mostly orange and moderate brown. Cell c mostly or entirely infuscated to subhyaline. C-band mostly orange; most of pterostigma moderate brown. C-band broadly extending to vein M in cell br along cell bm; covering base of cell r2+3; orange area posterior to pterostigma broad, extending distally into cells r1 and r2+3 except narrow anterior margin distally in cell r1 and narrow distal margin in both cells. C-band and S-band connected along vein R 4+5. Basal hyaline area between C-band and S-band extended to vein R 4+5. Cell bm entirely hyaline. Cell r 1 basomarginal hyaline spot triangular to rectangular, its apex aligned proximal to crossvein r-m. S-band mostly orange; base without posterior extensions in middle of cell cu1 or in cell a1; distal margin of band brown posteriorly in cells r4+5, dm and cu1; distal section brown along costal margin, distal part of cell r2+3 and in cell r4+5. S-band distal section at apex of vein R2+3 0.64–0.67 times width of cell r2+3; without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. Subapical hyaline area in radial cells distal to r-m extending anteriorly to vein R2+ 3. V- band proximal arm as dark as apical half of S-band; extending 0.74–0.79 distance from apex of vein Cu1 to apex of vein A1+Cu2; connected anteriorly to S-band along vein R4+5 or in cell r2+3. V-band distal arm complete; broadly connected to proximal arm. Apex of V-band not extended to vein M, hyaline area present between band and vein M. Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterodistal to it along vein Cu1. Area between S-band and V-band entirely microtrichose in cells dm and cu1.

Abdomen. Pale brown. Tergites without markings, entirely microtrichose; setulae pale brown.

Female terminalia ( Figs. 22–24 ). Oviscape entirely yellow to orange brown; straight; entirely microtrichose; 2.53–2.75 mm long; length ratio (oviscape length/mesonotum length) 0.68–0.79; spiracle at basal 0.35–0.40. Eversible membrane ( Fig. 24 ) with about 30 strong, hooklike denticles (all sclerotized) in subtriangular pattern.

Aculeus ( Fig. 22 ) 2.10–2.19 mm long; in ventral view parallel-sided (0.13–0.18 mm wide at midlength), extreme base expanded (0.25–0.28 mm wide), broadened at cloacal opening (0.13–0.20 mm wide). Aculeus length/ oviscape length 0.76–0.87. Aculeus tip ( Fig. 23 ) 0.29–0.32 mm long, 0.13–0.15 times aculeus length; width at base 0.16–0.18 mm; lateral margins gradually tapering, but with medial constriction (nonserrate part with margins concave); distal 0.21–0.24 mm with 17–23 small serrations, serrated part 0.66–0.77 times length of tip; serrations not extending onto dorsal side basally, and separated by less than width of serration.
