(Figs. 2, 5, 14‒16)
Diagnosis. Rhagoletotrypeta gelabertae belongs to the xanthogastra species group, as indicated by the presence of a sublateral white vitta on the scutum, and the lateral surstylus with a distinct anterior lobe. It differs from the other species of the xanthogastra group, except R. cubensis Norrbom and R. parallela Norrbom, in having the wing bands relatively broad and the scutum presuturally without brown markings between the dorsocentral lines. It differs from both species in having the basal brown area on the scutellum extending to the basal seta, and the sublateral white vitta on the scutum not extended to the intra-alar seta. It further differs from R. cubensis as follows: scutum with large lateral presutural brown markings; notopleuron entirely brown; and wing with subapical hyaline area extending slightly into cell r2+3, and cell bm brown apically. It further differs from R. parallela in having the discal and subapical bands diverging anteriorly, the presence of an accessory costal band, and in having the brown presutural sublateral area on the scutum connected to the brown area on the notopleuron.
Description. Body length 5.14 mm. Wing length 4.40 mm. Mesonotum length 2.08 mm. Body predominantly orange with dark brown to black markings. Setae very dark brown to black.
Head yellow to orange except reddish brown ocellar tubercle. Frons with 3 frontal and 2 orbital setae. Ocellar seta well developed. Facial carina strong, ventral half very broad. Antenna short, extended about half distance to ventral facial margin; first flagellomere 2.20 times as long as wide (on mesal side), rounded dorsoapically.
Thorax orange and dark brown, with following white or pale yellow areas: postpronotal lobe and small presutural lateral area on scutum extended posteriorly towards presutural supra-alar seta; medial and sublateral scutal vittae (unpaired medial vitta narrow, not extended laterally to base of acrostichal seta (0.6 times as wide as distance between acrostichal setae), and not reaching posterior scutal margin; paired sublateral vitta narrowly bordering medial part of transverse suture and extended posteriorly almost to level of postalar seta, not reaching intra-alar seta); distal four-fifths of disk of scutellum, and distal half laterally; rectangular area covering dorsal twofifths of anepisternum (extending ventrally almost to second large anepisternal seta); and greater ampulla. Dark brown areas including: scutum, except white areas and orange presutural area between dorsocentral lines and extending very narrowly along medial part of transverse suture; entire notopleuron; basal fifth of scutellum on disk, laterally extending to about midlength, well beyond basal seta; continuous broad mark covering most of ventral three-fifths of anepisternum (except narrowly bordering anterior spiracle and very narrowly on ventral margin) and entire anepimeron, katatergite, anatergite, subscutellum and mediotergite; and narrow stripe on katepisternum bordering white area ventrally. Dorsocentral seta aligned slightly posterior to level of postsutural supra-alar seta. Scutum nonmicrotrichose except for tiny postsutural lateral microtrichose area bordering wing base. Notopleuron entirely nonmicrotrichose. Scutellum entirely microtrichose. Legs mostly orange; tibiae mostly brown.
Wing (Fig. 5) predominantly hyaline with 5 relatively broad brown bands: subbasal band from crossvein h to base of vein CuA+CuP, filling all of cell bm (except subapical fold); discal band from distal part of cell c and pterostigma to posterior margin near midpoint between apices of veins CuA+CuP and M4, covering crossvein r-m but not extreme base of cell r2+3; narrow accessory costal band, extended from costa to vein R4+5; relatively broad subapical band, diverging anteriorly from discal band and separated from it on posterior margin; and broad anterior apical band, broadly connected to subapical band in cells r1 and r2+3, extending slightly posterior to apex of vein M1 (its width measured at apex of vein R4+ 5 2.25 times width of hyaline area between it and subapical band measured along vein R4+5). Hyaline area between subapical and anterior apical bands extended about one-third across cell r2+3. Crossvein r-m at 0.48 distance from crossvein bm-m to crossvein dm-m. Wing length/width ratio 2.44.
Abdomen mostly orange; tergites 3‒5 each with medially interrupted dark brown bands. Tergites evenly black setulose; tergite 5 with slightly larger apical setae.
Male terminalia (Figs. 14‒16) with medial surstylus short; lateral surstylus with distinct anterior (mesal) lobe and moderately long posterior lobe; glans relatively slender, strongly and complexly sclerotized, without distinctive apical or subapical lobes.
