### Anastrepha katiyari Norrbom

Body. Setae orange, or orange brown, or red brown.

Head. Frons with brown band or mark including ocellar tubercle and extending to eye margin (usually narrow, occasionally extended anteriorly beyond level of orbital seta, sometimes broader along eye margin). Anterior or single orbital seta anterior or mesal to brown band, or at margin of brown band, or within brown band. Occiput with brown marks only on medial sclerite, or with pair of brown marks on medial and lateral sclerites (with pair of spots or vittae laterally on medial sclerite or with curved vitta extending from ventral to lateral vertical seta onto medial sclerite). Medial occipital sclerite with brown marks restricted to lateral margins. Frontal setae 2–4 (usually 3–4). Orbital setae 1, or 2 (rarely). 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 2.6–3.2 mm (2.70–3.12, n=11). Scutum nonmicrotrichose (except on and lateral to sublateral vitta and on posterior margin). 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 dark orange, or orange brown, or 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 triangular, or with posterior end bilobed; 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. Mesopleuron mostly dark orange to brown. Subscutellum entirely brown to dark brown, or yellow to red brown medially, dark brown laterally. Mediotergite entirely brown to dark brown, or yellow to red brown medially, dark brown laterally. Femora entirely yellow to orange (femora yellow, mid and hind femora often with apex dark orange posteriorly, tibiae dark orange to pale brown, tarsi yellow). 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 not extending to vein M in cell br adjacent to cell bm; not covering base of cell r2+3; yellow or orange area posterior to pterostigma filling all of band in cells r1 and r2+3, or elongate, extending in cell r1 at least to level of one-third length of pterostigma but not into cell 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) covering at most anterior 2/3 of cell bcu, posterior third or more of bcu hyaline or faintly infuscated. Cubital streak (isolated base of S-band) extending at most slightly beyond bm-cu. Subapical hyaline area in radial cells distal to r-m extending anteriorly to vein R2+3. 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 extended to apex of vein M. V-band proximal arm as dark as apical half of S-band (extended only to or slightly anterior to vein M); not connected anteriorly to S-band. V-band distal arm absent. 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) 0.5–0.59 (0.51–0.57). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. 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 3.9–5.05 mm (3.95–4.99, n=11); length ratio (oviscape length/mesonotum length) 1.25–1.65 (1.27–1.64, n=11). Eversible membrane with dorsobasal denticles mostly small and weak, apical row very large, stout, strongly sclerotized, and divided medially. Aculeus length 3.1–4.6 mm (3.16–4.53). 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. Spermathecae membranous.

Miscellaneous. Sex of recorded specimens: male and female. Species group: daciformis group.

Biology and economic significance. This species is not considered economically important. Its only reported host plant is a species of Sideroxylon (Sapotaceae). Refer to the 'Tephritidae Databases' in the USDA Compendium of Fruit Fly Host Information (https://coffhi.cphst.org/) for host plant information.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
