Diagnosis. This species runs to p. 11 in the key of Steyskal (1977), but all of the species with an aculeus 2.0– 3.5 mm long differ in having the aculeus tip not expanded basally nor entirely serrate. The shape of the tip resembles that in A. rheediae Stone, A. lutzi Lima, and A. tecta Zucchi, but in those species the aculeus is less than 2.5 mm long. Anastrepha lopezi is also similar to A. enkerlini Hernández-Ortiz, but it lacks a brown spot on the scutoscutellar suture, the aculeus is slightly longer, 3.17 vs. 2.4–2.9 mm, and the length of tip from the broadest point is slightly shorter, 0.23 vs. 0.27–0.31 mm, and the tip shape differs, with the lateral margin distinctly concave basal to the serrate part and the basal margin of the serrate part slightly concave. The tip also resembles that of A. acris Stone, but is more extensively serrate, and the serrations are about half as large as in A. acris.
Description. Mostly yellow to orange, with white to pale yellow markings. Setae dark red brown to black. Head: Yellow to orange; ocellar tubercle brown; 3–4 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta absent. 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; with following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it; extremely slender medial scutal vitta, ovoid posteriorly and extended laterally to acrostichal seta; sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; scutellum except extreme base of disc; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite. Subscutellum and mediotergite entirely orange. Mesonotum 3.35 mm long. Postpronotal lobe, scutum, and scutellum entirely microtrichose; scutal setulae yellowish to brownish. Chaetotaxy typical for genus. Katepisternal seta poorly differentiated from setulae, onethird as long as anepisternal seta, weak, orange.
Legs: Entirely yellow to orange.
Wing (Fig. 31): Length 8.53 mm, width 3.34 mm, ratio 2.55. Apex of vein R1 at 0.57 wing length, distinctly proximal to level of anterior end of crossvein r–m. Cell c 1.04 times as long as pterostigma; pterostigma 4.26 times as long as wide. Vein R2+3 not sinuous. Crossvein r–m at 0.71 distance from bm–cu to dm–cu on vein M. Vein M very strongly curved apically; cell r4+5 0.75 times as wide at apex as at level of dm–cu. Cell bcu with distal lobe moderately long, length of bcu 1.52 times as long as anterior margin, lobe 0.65 times as long as vein A1+Cu2. Wing pattern mostly orange and moderate brown. C-band mostly orange; orange brown in pterostigma; distal margin in cells br, r1 and r2+3 partially narrowly brown. C-band and S-band broadly separated along veins R2+3 and R4+5 by hyaline band that extends from cell bm to costa, slightly narrowed along vein R4+5. Basal half of S-band mostly orange, posterodistal margin brown, very broadly in cell cu1, with weak incision in cell cu1, anterobasal margin narrowly brown anterior to vein M; distal section orange except margins narrowly brown, relatively narrow, at apex of vein R2+3 0.56 times width of cell r2+3, not extended to apex of vein M; hyaline area proximal to apex of band extending to vein R2+3. V-band incomplete; proximal arm mostly brown, portion in cell r4+5 mostly orange, extending faintly to vein M, separate from S-band anteriorly, on posterior margin extended at least four-fifths distance to vein A1+Cu2; distal arm isolated, extended anteriorly more than half width of cell r4+5.
Abdomen: Mostly orange, without brown markings. Setulae pale brown.
Female terminalia: Oviscape 3.29 mm long, 0.98 times as long as mesonotum, straight in lateral view, entirely orange; spiracle at basal 0.27. Eversible membrane (Fig. 53) with ca. 30 medium sized, hooklike dorsobasal denticles in 3–4 irregular rows in suboval pattern. Aculeus (Fig. 75) slightly ventrally curved in lateral view, 3.17 mm long, 0.96 times as long as oviscape, in ventral view base slightly expanded, 0.195 mm wide; shaft 0.11 mm wide at midlength; tip (Fig. 88) 0.25 mm long, 0.08 times aculeus length, 0.15 mm wide, 1.67 times as long as wide, flared outward at base, then triangular and minutely serrate, serrate part 0.92 times as long as tip, 1.53 times as long as wide, lateral margin slightly concave at base, then straight. Spermathecae not examined.
Distribution. Anastrepha lopezi is known only from Guatemala.
Biology. The host plants and other aspects of the biology of this species are unknown.
Type data. Holotype Ƥ (USNM USNMENT 00104579), GUATEMALA: Escuintla: Palín, Granja El Coronel, 1 Mar 1993, J. López, McPhail trap.
Etymology. This species is named in honor of Jorge López, the collector of the holotype, whose efforts have greatly advanced our knowledge of Anastrepha taxonomy and distribution in Guatemala.
Comments. The sagittate, finely serrate aculeus tip and the relatively small number of hooklike denticles of the eversible membrane suggest the relationship of A. lopezi with the spatulata group.
