Material examined. Type. Holotype ♀: “ Peru: Cuzco: Paucartambo / Puente San Pedro (50 km NW Pilcopata) / 13.1468W 71.6159S / 1600 m, 3 Sep. 1988 / leg. A. Freidberg ”. The holotype is in good condition and is to be deposited in the collection of TAUI.

Diagnosis. Ulivellia amnoni differs from all the other species of the genus by having the subbasal and discal bands in the wing connected, and therefore cell br entirely brown and crossvein dm-m bent basally in the apical fifth ( Fig. 4 A ).

Description. Female. Head ( Figs 50 B, C ) ratio (length: height: width) 1: 1.36: 1.56, mostly black, except frons, gena and parafacial brown. Frons 0.9× longer than wide (from lunule to anterior ocellus), orange brown with black ocellar triangle and vertical plates; orbits silver-white microtrichose, brown. Parafacial narrow, 0.2– 0.3× broader than postpedicel, slightly white microtrichose. Frontal plates with 6–7 parafrontal setulae and 5–7 frontal setae, frontal vitta with 4–6 interfrotal setae on each side, anterior ones the longest, about 1/3 as long as ocellar seta; 2 orbital setae, posterior longer than anterior, about 0.5–0.6× longer than inner vertical seta and 3–4× longer than outer vertical seta; postocellar long, 0.5× longer than inner vertical setae; outer vertical seta short, 0.2–0.25× longer than inner vertical seta and hardly distinguishable from postocular setae forming one row allied by 8–10 dorsal and 10–15 ventral occipital setae. Lunule very narrow, indistinguishable, orange-yellow. Eye 1.5× higher than long. Face (above suture) as high as wide at transverse fold, brown, obscured ventrally, densely white microtrichose; epistome brown to black, sparsely white microtrichose, metallic shining, often with greenish or cyan sheen, strongly produced anteriorly and separated from upper part of face by deep suture. Clypeus brown to black, sparsely white microtrichose, metallic shining, often with cyan sheen, 0.3–0.4× higher than epistome. Gena brownish yellow, with long genal seta and 3–4 peristomal setae anterior of it, 0.5–0.8× longer than genal seta. Occiput black, except postgena brown, with silver to cyan metallic sheen, moderate densely covered with white microtrichia partly hiding underlying cuticle; ventral part of occiput (postgena) with 4–5 setae almost as long as genal seta. Antenna brownish yellow; scape and pedicel with black setulae; postpedicel brown, blackish antero-dorsally, whitish microtrichose, 1.8× longer than wide, apically rounded; arista black except yellow at base, almost bare. Mouthparts black, prementum black, shining. Palp brown, yellowish apicoventrally with long black setulae, except for basal 1/4, with shorter setulae, about 0.3–0.5× longer than apical setulae.

Thorax ( Fig. 50 E ) black, metallic shining with yellowish-green in apical half or cyan sheen and sparse yellow microtrichia not hiding underlying cuticle. Mesonotal scutum 1.46× longer than wide; presutural area with silvery cyan sheen and without inconspicuous yellowish-green vittae, postsutural area with yellowish-green sheen, black setulose, with 8–10 rows of setulae between dorsocentral setulae; 1 pair of acrostichal setae; prescutellar area devoid of setulae. Scutellum dorsally flattened, black or brownish posteriorly, finely shagreened, sparsely microtrichose, devoid of setulae. Subscutellum subshining, black with metallic silvery cyan sheen. Mediotergite shining black with metallic silvery cyan sheen, sparsely microtrichose. Anepisternum, anepimeron as well as katepisternum with only metallic silvery cyan sheen. All the setae and setulae black.

Wing ( Fig. 4 A ) 5.6 mm (♀) long: 2.7× longer than wide, basicostal cell hyaline; costal cell very long, 8.2× longer than wide, brown in basal fifth, with costa almost straight, forming neither lobe nor cleft; pterostigma entirely brown, narrow triangular, 8× longer than wide, vein R 1 setulose dorsally at pterostigma level, ending at level of crossvein dm-m; vein R 2+3 at apex bent anteriorly and then subparallel to costa, turning towards it before very apex; vein R 4+5 arcuate, first upwards from crossvein r-m and downwards distally, ending just shy of wing apex; vein M 1 curved similarly but in opposite direction, ending well beyond apex of wing; crossvein r-m at basal ¼ of cell dm; crossvein dm-m bent basally in the apical fifth. Cell r 4+5 5.5–6× longer than wide, broadest just beyond the middle and apically narrowed; Cell m1 narrow triangular; ultimate section of M 1 3×. as long as crossvein dm-m and 1.5x as long as penultimate section. Vein CuA slightly convex in upper part, cell cua with short posteroapical lobe along vein CuP. Wing pattern similar to U. inversa and U. laetitiae , subbasal band broader and more or less oblique, not continued on alula, and connected with discal band therefore cell br entirely dark, discal band strongly arched, stronger than in U. inversa and U. laetitiae , broader at cell br and clearly narrowed at posterior end, preapical band slightly less arched than in U. inversa . Calypters white, with white ciliae. Halter light with light knob.

Legs ( Figs 50 A, D ) all entirely black bluish cyan sheen, except trochanters yellow-brown and knees narrowly brown, all sparse with microtrichia except for coxae of fore legs. Mid tibia ventrally with one spur-like seta 3× longer than tibia width.

Abdomen ( Fig. 50 F ) entirely black, tergites very finely shagreened and sparsely microtrichose, with metallic bluish cyan sheen, less shiny than pleura; setulae and setae black.

Male. Unknown.

Etymology. This species is named in honor of the late Dr. Amnon Freidberg, a renowned scientist with a huge knowledge on Tephritoidea , who collected the specimen. See Friedman (2019) for an account of his life and work.
