Rhagoletotrypeta xanthogastra differs from all other species of Rhagoletotrypeta in lacking microtrichia on the scutum and having the lateral scutal white mark on the transverse suture comma-shaped and not extended posteriorly beyond the postsutural supra-alar seta. Other useful diagnostic characters include: postpronotal lobe brown or white with brown margins; notopleuron entirely brown; scutellum with apical white area small, the basal scutellar seta within the dark brown area (basal seta in white area in other species except R. pastranai); wing with discal and subapical bands divergent anteriorly; accessory costal band at least faintly present; aculeus tip length less than 0.4 times aculeus length, apex in ventral view deeply trilobed; 3 spermathecae.

Classification and Evolutionary Relationships
Order: Diptera. Family: Tephritidae. Subfamily: Trypetinae. Genus: Rhagoletotrypeta. Species: annulata. Author: Aczél.

Specimen data
ARGENTINA: Córdoba: Sierra Zala, San Javier, reared ex fruit Celtis tala Gill., emerged Nov 1938, J. A. Pastrana, 2m "allotype" and "paratype" (IML, MACN).
ARGENTINA: Tucumán: Finca Horco Mde., 11 Jan 1953, 1f (IML).
ARGENTINA: Tucumán: Villa Padre Monti, 17 Jan - 7 Feb 1948, R. Golbach, 1f holotype (IML).

Biology
Rhagoletotrypeta xanthogastra breeds in fruit of Celtis tala Gill. (Ulmaceae), commonly known in Argentina as tala (Aczél 1954). The record from "ciruelo" (Aczél 1954) (probably a Spondias sp.) is doubtful. Other aspects of the biology of R. xanthogastra are poorly known.

Economic Significance
Rhagoletotrypeta xanthogastra is not considered economically important.
