Anastrepha ornata differs from all other species of Anastrepha in having the middle section of the S-band very slender, but the distal section broad. It is unusual in having the proximal arm of the V-band connected along the posterior wing margin to a basal extension of the S-band along vein A1+Cu2; within the serpentina group this occurs only in some A. pulchella. A. ornata further differs from the other species of the serpentina group in having the C-band and S-band well separated. It is one of the species with the thoracic pleuron largely brown and with the abdomen partially brown. It differs from the other predominantly brown species in having broad dorsocentral nonmicrotrichose areas on the scutum and the aculeus tip broadly triangular.

Classification and Evolutionary Relationships
Order: Diptera. Family: Tephritidae. Genus: Anastrepha. Species: ornata. Author: Aldrich.
Relationships among the species of Anastrepha were analyzed by Norrbom et al. (1999) and McPheron et al. (1999). Click here for more detailed discussion of Anastrepha phylogeny. Anastrepha ornata has been placed in the serpentina species group. Norrbom (2002) analyzed the relationships among the species of the serpentina group (see Phylogeny of the Anastrepha serpentina group), but could not resolve the relationships of A. ornata. It may be the sister taxon to A. striata Schiner + A. bistrigata Bezzi, but in some trees resulting from the analysis it was grouped with other species of the serpentina group.

Type Data
Holotype - Female (National Museum of Natural History (USNM), USNM52985), ECUADOR: Oriente, Baños [probably Tungurahua: Baños (1°24'S 78°25'W)], 6000 ft., 30 Oct 1922, F. X. Williams.

Distribution
Anastrepha ornata is known from Colombia, Ecuador, and Peru. In Colombia it is known only from Antioquia (Yepes & Vélez 1989, Norrbom 2002). In Ecuador, A. ornata has been reported from the provinces of Azuay, Chimborazo, Cotopaxi, Morona-Santiago, Napo, Pastaza, Pichincha, and Tungurahua (Stone 1942, Hedström 1987, Molineros et al. 1992, Tigrero 1998, Norrbom 2002). It was reported from Peru by Korytkowski (2001).

Biology
The following plants have been reported as hosts of A. ornata: Myrtaceae - Acca sellowiana (O. Berg) Burret (Yepes & Vélez 1989, as Feijoa sellowiana); Psidium guajava L. (Campos 1960, Hedström 1987, Molineros et al. 1992, Tigrero 1998); Syzygium jambos (L.) Alston (Tigrero 1998, as Eugenia jambos); Rosaceae - Prunus persica (L.) Batsch (Campos 1960, as Persica vulgaris); and Pyrus communis L. (Stone 1942, Campos 1960). Of these, only P. guajava is a native host. Pouteria lucuma (Ruiz & Pav.) Kuntze (Sapotaceae) was reported as a host by Tigrero (1998), but the record he cited from Aldrich (1925) was clearly based on a specimen that was collected on the plant and not reared.

Economic Significance
Anastrepha ornata is a minor pest of various Myrtaceae and Rosaceae, especially guava, in the Andean countries [refs.?].
