Diagnosis. Anastrepha juxtalanceola can be distinguished from other species of Anastrepha by the following combination of characters: Setae red brown to dark red brown; subscutellum and mediotergite entirely orange; cell c with subapical hyaline area; C-band mostly orange posterior to pterostigma; oviscape 2.44–2.72 mm long, 0.84– 0.95 times as long as mesonotum; aculeus 2.28–2.47 mm long; tip 0.130 –0.155 mm long, 0.065 –0.070 mm wide, somewhat saddle-shaped, distal 0.34–0.43 triangular, finely serrate. It resembles other species of the lanceola clade, but differs from most of them, including A. latilanceola Norrbom which has a similar aculeus tip and is sympatric with A. juxtalanceola in Suriname and Pará, Brazil, in having shorter terminalia (oviscape 3.00– 3.76 mm long, 1.09–1.22 times mesonotum length in A. latilanceola ). It further differs from A. kimi Norrbom , which has only slightly longer terminalia, and A. soroana Fernández & Rodríguez , which has similar length terminalia, in having a relatively broader aculeus tip and the C-band and S-band often connected. In the key of Zucchi et al. (2011) A. juxtalanceola runs to A. montei Lima, but differs in having vein M 1 less strongly curved apically and a less tapered aculeus with a longer, saddle-shaped tip.

Five sequences of A. juxtalanceola , from four adult specimens from Brownsberg ( MT672225 View Materials , MT672226 View Materials , MT672228 View Materials , MT672228 View Materials ) and one from Berg en Dal ( MT672227 View Materials ), Suriname, were included in the COI barcode analysis of Moore et al. (in prep.). There were four unique sequences. The five sequences of A. juxtalanceola formed a cluster with five sequences of A. latilanceola , three sequences of an undescribed species near A. tumbalai , and one sequence of A. ericki Norrbom , which also belong to the lanceola clade. Thus, there is no COI barcode gap for this species. The A. juxtalanceola COI barcodes display a range of intraspecific K2P distances from 0.0–1.0%. The smallest interspecific K2P distances were ca. 0.5% with A. latilanceola , A. sp. nr. tumbalai , and A. ericki .

Etymology. The name of this species is a Latin adjective, formed from juxta, meaning like or near, combined with lanceola , the name of a related species.

Comments. This species belongs to the lanceola clade of the mucronota species group as indicated by the mostly nonmicrotrichose scutum, the wing shape (somewhat elongate, with anterior margin relatively straight) and wing pattern (particularly the hyaline area in cell c, the narrow basal half of the S-band, and the proximal arm of the V-band often constricted or interrupted in cell r), the slender female terminalia and phallus, the long but relatively few dorsobasal denticles on the eversible membrane, the somewhat saddle-shaped aculeus tip, with the lateral margin concave medially, and with the apex triangular and finely serrate. In a preliminary phylogenetic analysis using anchored hybrid enrichment (Wiegmann et al., in prep.), A. juxtalanceola is grouped with A. lanceola and A. latilanceola , the other species of the lanceola clade included in the analysis. In the COI analysis of Moore et al. (in prep.), A. juxtalanceola clusters with seven other species of the lanceola clade.
