Diagnosis. Anastrepha cheslavoi resembles species of the serpentina group, especially three species with the C- and S-bands broadly fused, and cell br without a hyaline area distal to crossvein bm-m. It differs from these three species, A. anomoiae Norrbom , A. pulchella Norrbom and A. pulchra Stone , in having all abdominal tergites orange without brown markings or bands, predominant color of the mesonotum orange, wing color pattern predominantly orange, shorter terminalia (oviscape length 2.3 mm, aculeus length 1.92 mm vs. both over 3.0 mm in the other 3 species), and the proximal arm of the V-band extended anteriorly only to vein M 1 or very faintly into cell r 4+5 vs. at least partially distinct in cell r 4+5). In the keys of Steyskal (1977) and Norrbom (2002), A. cheslavoi runs with some difficulty to A. pulchra Stone , which differs additionally in having brown markings on the orbital plate and occiput and lacking serrations on the aculeus tip.

Description. Mostly orange. Setae dark brown to black.

Head: Yellow to orange except brown ocellar tubercle. 4–5 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most 2 times longer than ocellar tubercle. Facial carina, in profile, concave. Antenna extended 0.75–0.80 distance to ventral margin of face. Palpus in lateral view dorsally curved, evenly setulose.

Thorax ( Fig. 2 ): Mostly orange, scutum mostly dark orange, with very slender and faint red brown dorsocentral vitta, extended anteriorly to transverse suture and posteriorly curving slightly laterally, ending in darker brown mark between dorsocentral and intra-alar lines; scuto-scutellar suture with single broad irregular medial brown spot; area between posterior brown marks slightly darker orange brown than rest of scutum. Following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it; sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; scutellum except extreme base; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite; medial scutal vitta, slender anteriorly, ovoid posteriorly, extending laterally to midway between acrostichal and dorsocentral seta. Subscutellum entirely orange; mediotergite orange medially, dark brown laterally. Mesonotum 3.10–3.27 mm long. Postpronotal lobe, notopleuron, scutum and scutellum entirely microtrichose; scutal setulae brown. Chaetotaxy typical for genus. Katepisternal seta undifferentiated from setulae or absent.

Legs: Entirely yellow to orange.

Wing ( Figs. 6–7 ): Length 7.16–7.18 mm, width 2.77–2.94 mm, ratio 2.40–2.53. Apex of vein R 1 at 0.55–0.58 wing length, proximal to level of anterior end of crossvein r-m. Cell c 1.37–1.54 times as long as pterostigma; pterostigma 2.97–3.36 times as long as wide. Vein R 2+3 not sinuous. Crossvein r-m at 0.68–0.70 distance from bmm to dm-m on vein M 1. Vein M 1 moderately curved apically; cell r 4+5 0.96–1.04 times as wide at apex as at level of dm-m, 0.90 times as wide as maximum subapical width. Cell cu a with distal lobe relatively short, length of cu a 1.49–1.59 times as long as anterior margin, lobe 0.58–0.71 times as long as vein CuA+CuP. Wing pattern mostly orange. C-band mostly orange, without hyaline area in cell c, pterostigma mostly pale brown; cell br with large dark brown transverse mark at level of crossvein h and base of cell bm, area anterior to cell bm with irregular orange brown markings; fork of vein Rs with narrow dark brown spot. C-band and S-band broadly connected from base to vein R 2+3; cell bm pale orange brown, base of cell dm and apical half of cell br entirely orange, without hyaline areas; hyaline marginal spot in cell r 1 ovoid to triangular, extended near or touch to vein R 2+3, with apex aligned with or distal to crossvein r-m. Basal half of S-band mostly orange, posterodistal margin partly to mostly narrowly pale brown, more broadly in cell m 4, extended to apex of lobe of cell cu a; distal section mostly orange, narrowly pale brown on most of margins in cell r 2+3 and in cell r 4+5, slender, at apex of vein R 2+3 0.21–0.23 times width of cell r 2+3, not extended to apex of vein M 1, without marginal hyaline areas; hyaline area proximal to apex of band extended to vein R 2+3. V-band with proximal arm narrow, mostly pale brown, narrowly orange along crossvein dm-m, extended anteriorly only to vein M 1 or sometimes faintly into cell r 4+5, on posterior wing margin extended approximately three-fourths distance to vein CuA+CuP; distal arm absent.

Abdomen: Mostly orange, without brown markings.

Male terminalia ( Figs. 43–44 ): Epandrium in lateral view shorter than high. Lateral surstylus relatively long, extended beyond prensisetae by 3.2–3.4 times length of prensiseta; in lateral view elongate, apex blunt and posteriorly curved, lateral margin straight or slightly concave or convex. Proctiger with lateral and ventral sclerotized areas separated. Phallus 2.0– 2.5 mm long, 0.61–0.80 times as long as mesonotum; glans 0.6 mm long.

Female terminalia ( Figs. 19 , 23 , 32 ): Oviscape 2.30 mm long, 0.70 times as long as mesonotum, straight in lateral view; entirely orange; spiracle at basal 0.36. Eversible membrane ( Fig. 19 ) with dorsobasal denticles in subovoid pattern, with 30–35 relatively short and thick hooklike denticles in 4–5 irregular rows. Aculeus ( Fig. 23 ) straight in lateral view, 1.92 mm long, 0.83 times oviscape length; in ventral view base distinctly expanded, 0.24 mm wide, shaft 0.11 mm wide at midlength; tip ( Fig. 32 ) 0.25 mm long, 0.13 times aculeus length, 0.12 mm wide, 2.08 times as long as wide; in ventral view parallel-sided or slightly narrowed basally, distal 0.80 triangular, gradually tapered, very finely serrate, apically acute, lateral margin of triangular part straight or very slightly convex; 0.04 mm wide in lateral view, 0.33 times ventral width. Spermathecae not examined.

Distribution. Anastrepha cheslavoi is known only from Colombia (Casanare Department), from the region is known as “Piedemonte llanero” because of its overlapping Andean and Orinoquian natural regions.

Biology. The host plants and other aspects of the biology of this species are unknown.

Etymology. This species is named in recognition of the late Cheslavo A. Korytkowski, professor of the Programa Centroamericano de Maestría en Entomología (PCMENT) of the Universidad de Panamá, a passionate researcher on fruit flies and who for decades mentored and inspired many entomologists from Latin America.

Comments. This species could possibly be an aberrant member of the serpentina species group, although it lacks brown markings on the abdomen and the wing pattern is almost entirely orange, not predominantly brown, which Norrbom (2002) considered synapomorphies of the species currently in the serpentina group (sensu Norrbom et al. 2012). The extent of the pattern (cell br without hyaline area reaching vein R 4+5; distal section of S-band very slender; distal arm of V-band absent) does resemble some species of the serpentina group. The shape of the aculeus tip (finely serrate as in most species of the serpentina group) and the surstyli are not inconsistent with placement in the serpentina group.
