Diagnosis. Anastrepha neptis can be distinguished from other species of Anastrepha by the following combination of characters: Subscutellum entirely orange; mediotergite brown laterally; aculeus 1.26–1.66 mm long; aculeus tip with distal 0.36–0.49 slightly expanded, distal 0.49 or less minutely serrate or nonserrate. In the key of Zucchi et al. (2011) A. neptis runs to A. bahiensis Lima, from which it differs in having the subscutellum entirely orange, the V-band complete (usually incomplete in A. bahiensis ), and the aculeus tip more finely or not serrate. It is also similar to some other species of the fraterculus group, including A. amita Zucchi , from which it differs in having the aculeus tip longer compared to aculeus length (tip 0.19–0.22 times aculeus length vs. 0.16–0.17 in A. amita ) and more rapidly tapered and with finer or no serrations; A. canalis Stone and A. compressa Stone , from which it differs by having a longer aculeus tip with finer or no serrations and the lateral margin not dorsally curved; A. obliqua (Macquart) , from which it differs in having the aculeus tip longer and less extensively and more finely or not serrate; A. perdita Stone , from which it differs in having the V-band separate from the S-band, and the aculeus tip longer and less extensively and more finely or not serrate; A. sobrina Norrbom , from which it differs in having fewer hooklike dorsobasal denticles on the eversible membrane and the aculeus tip longer and less extensively and more finely or not serrate; and A. suspensa (Loew) , from which it differs in having the distal section of the S-band narrower, and the aculeus tip longer and more finely or not serrate. The aculeus tip resembles A. belenensis Zucchi , from which A. neptis differs in having the mediotergite brown laterally, and shorter terminalia (aculeus 2.50 mm long in A. belenensis ).

Two sequences of A. neptis ( MT672223 View Materials , MT672224 View Materials ), both from adult specimens from Brownsberg, Suriname, were included in the COI analysis by Moore et al. (in prep.). Both of the sequences are unique. Although many species of the fraterculus group cannot be distinguished by COI sequences, the sequences of A. neptis form a distinct cluster (i.e., with a COI barcode gap), with an intraspecific K2P distance of 0.2%. The smallest interspecific K2P distances were about 1.0% with specimens of the A. fraterculus complex from Ecuador ( MT884312 View Materials ) and Peru ( MN454443 View Materials ). Two subsequently obtained COI sequences, from adults from Brownsberg ( MZ702883 View Materials ) and Yasuní, Ecuador ( MZ702884 View Materials ) are identical to sequence MT672223 View Materials . A single partial ITS1 sequence from a female from Yasuní, Ecuador also differs from other species of the fraterculus group.

Etymology. The name of this species is a Latin noun in apposition meaning niece or granddaughter, following the theme of naming some species of the fraterculus group for family members ( fraterculus = little brother; sororcula = little sister; amita = aunt; matertela = aunt).

Comments. This species belongs to the fraterculus species group as indicated by the lateral brown marks on the mediotergite and the shape of the aculeus tip. In the COI analysis by Moore et al. (in prep.) the two sequences of A. neptis were grouped with other species of the fraterculus group.
