Anastrepha tenebrosa can be distinguished from other species of Anastrepha by the following combination of characters: Scutum without medial white to yellow vitta; cell bm mostly to entirely infuscated, at most orange only medially; and S-band with middle section mostly brown, at most with small orange area posteriorly in cell br and/or small mottled orange area in cell r 2+3 . It differs from most other species of Anastrepha by its predominantly brown wing pattern, with the C-band and S-band broadly connected, and the V-band complete, broadly connected to the S-band anteriorly and also connected to it in cell dm. In wing pattern it resembles A. brunnealata Norrbom & Caraballo , A. caudata Stone , A. concava Greene , A. fuscoalata Norrbom , A. hendeliana Lima and A. melanoptera Norrbom , which have the C-band and S-band connected in cell dm or at least the hyaline area between them narrowed. It differs from A. brunnealata and A. fuscoalata in lacking an orange area in the C-band posterior to the pterostigma, from all of these species except A. concava in having the aculeus tip nonserrate, from A. concava in having vein M 1 more strongly curved apically, shorter terminalia, and a much shorter aculeus tip, and from A. melanoptera in having larger and more sclerotized hooklike dorsobasal denticles on the eversible membrane, longer terminalia, and a broader aculeus tip. The shape of the aculeus tip in A. tenebrosa is also distinctive, with its lobelike expansions near midlength. The tip somewhat resembles species of the doryphoros group. The pattern of denticles on the eversible membrane, which almost connect ventrally, resembles that of A. acca Norrbom. In the key of Zucchi et al . (2011) A. tenebrosa runs to A. isolata Norrbom & Korytkowski , from which it differs in lacking an extension from the S-band in cell m 4 , having much longer terminalia, and a non-serrate aculeus tip, to A. furcata Lima , from which it differs in having longer terminalia and the aculeus not dorsally curved, or to A. hendeliana . Two sequences of A. tenebrosa ( MT763883 , MT763884 ), both from adult specimens from ExplorNapo, Peru , were included in the COI barcode analysis of Moore et al . (in prep.). Both are unique, and they formed a separate cluster (i.e., with a COI barcode gap), with an intraspecific K2P distance of 0.6%. The smallest interspecific K2P distance was 8.4% with A. sodalis . Description. Mostly yellow to orange. Setae dark red brown to black. Head: Yellow to orange except brown ocellar tubercle. 4–6 frontal setae; 2 orbital setae, posterior seta well developed.

This species has not been assigned to a species group. In wing pattern it resembles the species of the caudata group, and to a lesser extent A. concava Greene , which has the base of the S-band entirely brown. Unlike the caudata group, however, A. tenebrosa lacks the medial scutal vitta and its aculeus tip is nonserrate, with a large steplike margin, somewhat resembling species of the doryphoros group. The surstyli in the male are at least superficially similar to those of A. concava . In a preliminary phylogenetic analysis using anchored hybrid enrichment (Wiegmann et al ., in prep.), A. tenebrosa is clustered with A. conjuncta Hendel , the only species of the doryphoros group included in the analysis. In the COI analysis of Moore et al . (in prep.), A. tenebrosa clusters closest to A. sodalis Stone and an undescribed species from Ecuador . The single female from Pará, Brazil has the aculeus tip broken, and is relatively small, with shorter terminalia, but is tentatively considered to be conspecific with the Peruvian females.
