Diagnosis. Anastrepha crassaculeus can be distinguished from most species of Anastrepha by its dorsally curved aculeus, and from all other species by its aculeus shape, which in ventral view is broadest near midlength. Other useful diagnostic characters include: Scutum with slightly to distinctly darker orange brown band on posterior margin, not extended to intra-alar seta; S-band with posterior extension in cell m 4 not reaching posterior wing margin and not connected to proximal arm of V-band; C-band and S-band broadly connected; V-band complete, connected to S-band; vein M 1 not reaching S-band; eversible membrane with dorsobasal denticles in slightly elongate pattern; and aculeus short, tip very short, broad and nonserrate. In the key of Zucchi et al. (2011) A. crassaculeus runs to A. flavipennis Greene or A. belenensis Zucchi , from which it differs in aculeus length and shape, and in having the S-band with a posterior extension in cell m 4, among other characters.
Three sequences of A. crassaculeus ( MT 672185 View Materials – MT 672187 View Materials ), all from adults from Brownsberg , Suriname, were included in the COI barcode analysis of Moore et al. (in prep.). All three sequences are unique, and they formed a separate cluster (i.e., with a COI barcode gap), with a range in intraspecific K2P distance of 0.2–0.4%. The smallest interspecific K2P distance was 9.8% with A. fenestrella Norrbom & Korytkowski .
Description. Mostly orange. Setae red brown to dark red brown.
Head: Mostly yellow to orange, except ocellar tubercle brown. 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, 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 but sometimes poorly differentiated: postpronotal lobe and lateral margin of scutum bordering it; medial scutal vitta, broadly quadrate posteriorly, extending laterally to dorsocentral seta; sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; scutellum except extreme base; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite. Scutum with slightly to distinctly darker orange brown band on posterior margin, not extended to intra-alar seta. Subscutellum and mediotergite entirely orange. Mesonotum 3.19–3.65 mm long. Postpronotal lobe, notopleuron, scutum and scutellum entirely microtrichose; scutal setulae orange, evenly distributed sublaterally. Chaetotaxy typical for genus. Katepisternal seta weak, orange, less than half length of anepisternal seta.

Etymology. The name of this species is a noun in apposition, from the Latin crassus (fat, thick) and aculeus in reference to the shape of the aculeus.
Comments. This species belongs to the robusta species group as indicated by the dark posterior band on the scutum, the wing pattern (C-, S- and V-bands connected; base of S-band with posterior extension and distinct incision), and the dorsally curved aculeus. In a preliminary phylogenetic analysis using anchored hybrid enrichment (Wiegmann et al., in prep.), A. crassaculeus is clustered with the four other species of the robusta group included in the analysis. In the COI analysis of Moore et al. (in prep.), the three sequences of A. crassaculeus form a cluster as the sister group to multiple species of the robusta clade of the robusta group.
