Diagnosis. This species is similar to A. acuminata Canal, but differs in the shape and serration of the aculeus tip, which is more serrate and with the serrate part less tapered. In the key of Zucchi (2000a) A. matogrossensis runs to A. dissimilis Stone and in that of Steyskal (1977) it runs to that species or A. chiclayae Greene, but it differs from both species in its less elongate and more serrate aculeus tip. This species may vary in the connection of the C-band and S-band, and if these bands are sometimes connected the specimens would run to A. lutzi Lima in the key of Zucchi (2000a) and to A. rheediae Stone or A. ethalea (Walker) in that of Steyskal (1977). It differs from A. rheediae in the shape of the hook-like dorsobasal scales of the eversible membrane, which do not have elongate bases. It differs from all three species in the shape of the aculeus tip. The tip in A. matogrossensis is not as broad nor outwardly flared basal to the tip as in A. rheediae and A. lutzi, and it is less triangular with the lateral margin more curved than in both of those species. It is also more elongate than in A. rheediae (length/width ratio of broadest part approximately 2.0 in A. matogrossensis and 1.5 in A. rheediae). It is not as elongate as in A. ethalea which has an aculeus tip similar to those of A. dissimilis and A. chiclayae.
Description. Mostly dark orange, with white to pale yellow markings. Setae dark red brown.
Head: Yellow to orange except brown ocellar tubercle. Frons with 3–4 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, 1.2 times as long as ocellar tubercle. Facial carina, in profile, slightly concave dorsally and medially. Antenna extended 0.70 distance to ventral facial margin.
Thorax: Mostly dark orange, without brown markings, with following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it; medial scutal vitta, slender except posterior fourth strongly expanded and rounded, extended laterally almost to dorsocentral seta; paired 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. Subscutellum and mediotergite entirely orange. Mesonotum 3.65 mm long. Postpronotal lobe, scutum and scutellum entirely microtrichose; scutal setulae yellowish. Chaetotaxy typical for genus. Katepisternal seta weak, ca. twice as long as setulae, orange.
Legs: Entirely yellow to orange.
Wing (Fig. 1): Length 8.80 mm, width 3.60 mm, ratio 2.44. Apex of vein R1 at 0.57 wing length. Cell c 1.13 times as long as pterostigma; pterostigma 4.0 times as long as wide. Vein R2+3 not sinuous. Crossvein r-m at 0.67 distance from bm-cu to dm-cu on vein M. Vein M strongly curved apically; cell r4+5 0.72 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.45 times as long as anterior margin. Wing pattern orange and moderate brown. C-band mostly orange; most of pterostigma, part of band in cell br, and narrow distal margin of band in cells r1 and r2+3 brown. C-band and S-band separated, hyaline area between them slightly narrowed along vein R4+5. Cell dm with basal hyaline area relatively small. S-band with margins, except proximal margin in cell dm, mostly narrowly brown, distal margin broadly brown posteriorly in cell dm and in cell cu1; posterior margin without incision in cell cu1; distal section of band relatively narrow, at apex of vein R2+3 0.47 times width of cell r2+3, even in width, separated from apex of vein M, brown along costal margin, in distal part of cell r2+3, and in r4+5; hyaline area proximal to apex of band extending to vein R2+3. V-band complete, brown except most of proximal arm in cell r4+5 and anterior half of distal arm in that cell, proximal arm separated from S-band, with basal extension along wing margin extending more than two-thirds distance to vein A1+Cu2; distal arm slender, connected to proximal arm and extending to vein R4+5.
Abdomen: Mostly orange, without brown markings.
Female terminalia: Oviscape 2.93 mm long, 0.80 times as long as mesonotum, straight in lateral view, entirely orange; spiracle at basal 0.34. Eversible membrane not dissected, with approximately 40 hook-like dorsobasal scales (visible through oviscape). Aculeus straight in lateral view, 2.70 mm long, 0.92 times oviscape length; in ventral view base (Fig. 6) very slightly expanded (broken on right side in holotype); shaft nearly parallel-sided, distal fourth slightly tapering, 0.20 mm wide at midlength; tip (Fig. 7) 0.22 mm long, 0.08 times aculeus length, 0.115 mm wide, 1.91 times as long as wide, 0.06 mm wide in lateral view, 0.52 times ventral width, distal 0.23 mm of aculeus serrate, serrate part 1.05 times as long as tip, in ventral view elongate triangular, in lateral view serrations slightly more to dorsal side. Spermathecae not examined.
Distribution. Anastrepha matogrossensis is known only from Brazil (Mato Grosso).
Biology. The host plants and other aspects of the biology of this species other than date of capture of the holotype are unknown.
Type data. Holotype female (UFGD USNMENT 00671880), BRAZIL: Mato Grosso: Chapada dos Guimarães, Fonte de Água Mineral Lebrinha, 15°27'22"S 55°45'04.5"W, McPhail trap A3, 7 Mar 2005, M. Uchôa & A. Pontes.
Etymology. The name of this species is derived from the state of the type locality.
