Diagnosis. Anastrepha microstrepha   can be distinguished from other species of Anastrepha   by the following combination of characters: Frons and vertex with narrow U-shaped or pair of separated brown spots not extended laterally to eye; C-band and S-band connected, hyaline mark in cell r 1 aligned with or distal to crossvein r-m; C-band predominantly orange posterior to pterostigma. As in other species of the cryptostrepha   species group, it has vein M 1 weakly curved apically, the S-band and V-band connected, the aculeus tip narrow (<0.10 mm wide), deep, and nonserrate, and the proctiger sclerites connected dorsally. It is most similar to A. cryptostrepha Hendel   , from which it differs in having the C-band predominantly orange posterior to the pterostigma and longer terminalia (oviscape 5.23–6.89 mm long, 2.03–2.27 times as long as mesonotum vs. 4.27–4.50, 1.40–1.41 in A. cryptostrepha   ); A. cryptostrephoides Norrbom & Korytkowski   from which it differs by the position of the r 1 hyaline mark and having shorter terminalia (oviscape 6.91–8.22 mm long, 2.32 times mesonotum length in A. cryptostrephoides   ); and A. disticrux Norrbom & Korytkowski   , from which it differs in having the brown posterior scutal band, the position of the r 1 hyaline mark, and longer terminalia (oviscape 3.24 mm long, 1.40 times mesonotum length in A. disticrux   ).

In the key of Zucchi et al. (2011) A. microstrepha   runs to A. concava Greene   , from which it differs in having the wing pattern largely orange and the aculeus tip much shorter, A. flavipennis Greene   , from which it differs in having cell bm hyaline, and much longer terminalia, or A. belenensis Zucchi   , from which it differs in having the V-band complete and connected to the S-band and much longer terminalia. It also differs from all three of these species in having the hyaline marginal mark in cell r 1 aligned with or distal to crossvein r-m.

Six sequences of A. microstrepha   ( MT672143 View Materials MT672148 View Materials ), all from adult specimens from Brownsberg, Suriname, were included in the COI barcode analysis of Moore et al. (in prep.). There were three unique sequences. The six sequences of A. microstrepha   formed a separate cluster (i.e., with a COI barcode gap), with a range in intraspecific K2P distance of 0.0–0.6%. The smallest interspecific K2P distance was 1.6% with A. cryptostrepha   .

Description. Mostly yellow to orange. Setae dark red brown.

Head: Mostly yellow to orange, ocellar tubercle brown, vertex with bown marking, typically narrow, shallow and U-shaped or linear and connected to posterior margin of ocellar tubercle, usually curving forward to or towards posterior orbital seta, not extended laterally to eye, sometimes divided into pair of brown marks not connected to ocellar tubercle; sometimes connected to brown mark on occiput. Medial occipital sclerite often with pair of dotlike red brown spots at midheight and sometimes with diffuse brown medial mark or larger somewhat V-shaped mark connected to but paler than brown mark on vertex. 2–4 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, subequal in length to as ocellar tubercle or absent. Facial carina, in profile, straight or concave on dorsal two-thirds. Antenna not extended to ventral facial margin. Palpus in lateral view dorsally curved, evenly setulose.

Thorax: Mostly yellow to orange, most of scutum orange; with following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it; sublateral scutal vitta from transverse suture to intra-alar seta or posterior margin, often faint or poorly differentiated posteriorly; scutellum except sometimes extreme base; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite. Medial scutal vitta absent. Scutum with narrow brown band on posterior margin, extended to base of intra-alar seta. Subscutellum diffusely brown laterally or entirely orange; mediotergite narrowly brown medially or laterally or both or entirely orange. Mesonotum 2.32–3.24 mm long. Postpronotal lobe, notopleuron, and scutellum microtrichose, scutum nonmicrotrichose except postsutural lateral margin lateral to postsutural supra-alar seta; scutal setulae pale brown, evenly distributed sublaterally. Chaetotaxy typical for genus. Katepisternal seta weak, orange, at most half length of anepisternal seta.

Legs: Entirely yellow to orange.

Etymology. The name of this species is a noun in apposition derived from the Greek mikros (little) and strepho (turn), in reference to the weak apical curvature of vein M 1.

Comments. This species belongs to the cryptostrepha   species group, as indicated by the weak apical curvature of vein M 1, the wing pattern with the C-band and S-band connected and S-band and V-band connected, the dorsally connected proctiger sclerites, and the short, deep, nonserrate aculeus tip (Norrbom & Korytkowski 2009). In a preliminary phylogenetic analysis using anchored hybrid enrichment (Wiegmann et al., in prep.), A. microstrepha   is clustered with A. cryptostrepha   , the only other species of the cryptostrepha   group included in the analysis. In the COI analysis of Moore et al. (in prep.), the sequences of A. microstrepha   cluster with those of A. cryptostrepha Hendel   , A. cryptostrephoides Norrbom & Korytkowski   , and A. cordata Aldrich   , the only species of the cryptostrepha   group included.
