Body. Setae orange, or orange brown.
Head. Frons with brown band or mark including ocellar tubercle and extending to eye margin (usually rectangular or rounded anteriorly, broad). Anterior or single orbital seta at margin of brown band, or within brown band. Occiput with pair of brown marks on medial and lateral sclerites (with curved brown vitta extending from ventral to lateral vertical seta onto margin of medial sclerite). Frontal setae 3–4. Orbital setae 1. Ocellar seta weak, small or absent. Gena with brown spot below eye. Facial carina in profile concave or flat on dorsal 2/3. Face with ventral part gradually tapered laterally; without brown markings. Antenna extended to or beyond ventral margin of face.
Thorax. Mesonotum length 3.6–4.2 mm (3.66–4.08, n=5). Scutum microtrichose except paired elongate bare areas (with very narrow, paired, nonmicrotrichose vitta on dorsocentral line, also bare medially anterior to transverse suture). Scutellum disc entirely microtrichose. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length; postpronotal seta on posterior half of postpronotal lobe. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Mesonotum medium brown, or dark brown; with presutural lateral pale vitta on lateral margin of scutum and posterior part of notopleuron (including posterior corner). Scutum presutural dorsocentral pale vitta present and connected anteriorly with pale area of postpronotal lobe; with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta with posterior end bilobed (Y-shaped, lobes slender); pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings (scutum predominantly brown). Scutum without brown vittae. Scutellum with at least basal third of sides and disk brown or orange, distinctly darker than apex. Propleuron yellow to orange, much paler than darker area on anepisternum, or mostly yellow to orange, dorsal margin narrowly brown. Mesopleuron mostly dark orange to brown. Subscutellum entirely brown to dark brown. Mediotergite entirely brown to dark brown. Femora at least one femur partly to entirely brown (femora yellow with distal third to half brown, tibiae brown, basitarsi yellow, rest of tarsi orange). Fore femur with posterodorsal and ventral rows of well developed setae.
Wings. Wing pattern with basal half of S-band reduced to streak in cubital cells, costal band continuous to wing apex, proximal arm of V-band variable. Cell c mostly or entirely infuscated to subhyaline, or paler posteriorly, without distinct subapical hyaline area. C-band broadly extending to vein M in cell br along cell bm; covering base of cell r2+3; yellow or orange area posterior to pterostigma filling all of band in cells r1 and r2+3. Cell bm entirely hyaline or infuscated only along subapical fold. S-band base without extension in cell a1 to or almost to posterior margin. Cubital streak (isolated base of S-band) entirely covering cell bcu. Cubital streak (isolated base of S-band) extending, sometimes faintly, along both sides of vein Cu1 to dm-cu. Subapical hyaline area in radial cells distal to r-m S-band entirely covering cell r2+3 distal to r-m. S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. S-band distally not extended to apex of vein M. V-band proximal arm absent or diffuse and much paler than apical half of S-band. V-band distal arm absent. S-band distal section width ratio (width of S-band/width of cell r2+3, both measured perpendicular to costal margin at apex of vein R2+3) 1. Vein R2+3 without accessory vein. Vein R4+5 distal to crossvein r-m more or less evenly curved or not strongly bowed medially. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.61–0.67 (0.62–0.65). Crossvein dm-cu orientation with anterior end more distal than posterior end.
Abdomen. Epandrium posterodorsal margin evenly rounded. Lateral surstylus in posterior view very short, barely extended beyond prensisetae, rounded apically. Lateral surstylus in posterior view not boot-shaped. Lateral surstylus in lateral view short, apex blunt. Phallus length 0.1–0.3 mm. Glans absent. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape straight; length 7.2–7.9 mm (7.32–7.78, n=5); length ratio (oviscape length/mesonotum length) 1.8–2.05 (1.83–2.00, n=5). Eversible membrane with dorsobasal denticles mostly small and weak, apical row very large, stout, strongly sclerotized, and divided medially. Aculeus length 6–6.8 mm (6.41). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip slender, needle-like, with circular cross-section; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically. Spermathecae membranous.
Sex of recorded specimens: male and female. Species group: daciformis group.
This species is not considered economically important. Its host plants are unknown, although it probably attacks fruits of species of Sapotaceae like other species of the daciformis species group. Refer to the Fruit Fly Databases for host plant information.
